This extraordinary epiphytic fern, with its distinctive crown-like appearance and dramatic, pendulous fronds, inspires a profound sense of awe and wonder. This report delves into the intricate botanical details, specific care requirements, and the rewarding journey of cultivating this magnificent plant, offering both comprehensive knowledge and a unique “time lapse” narrative of its growth.
Platycerium Coronarium: A Detailed Botanical Profile
Classification and Natural Habitat
Platycerium coronarium (O.F. König ex Muller) Desv., known by common names such as Crown Staghorn Fern, Crowned Elkhorn, or Royal Staghorn, is a distinguished member of the Polypodiaceae family, a genus encompassing 17 accepted species. Its classification places it firmly within the realm of true ferns, lacking flowers or seeds and reproducing via spores.
A defining characteristic of P. coronarium is its epiphytic nature. This means it naturally grows on other plants, primarily large trees, using them for physical support rather than as a parasitic host. This fundamental aspect of its biology profoundly influences its cultivation needs. Unlike terrestrial plants,
P. coronarium does not root in soil in its native environment, instead thriving attached to tree branches. This adaptation to an arboreal existence is a primary factor dictating its unique care requirements in cultivation. Successful growth hinges on replicating these natural conditions, particularly concerning mounting, watering, and humidity, rather than treating it like a typical potted plant. This explains why mounting is consistently recommended as an ideal method, as traditional potting mixes often lead to root rot.
The indigenous range of P. coronarium spans maritime Southeast Asia and Indochina, including regions such as Myanmar, Thailand, Cambodia, Vietnam, Sumatra, Java, Peninsular Malaysia, Singapore, Borneo, and the Philippines. In these tropical and subtropical areas, it is commonly found settled on the upper branches of mature trees within mangroves, lowland rainforests, and even along roadsides. This widespread distribution in its native habitat, often on old trees, indicates its robust nature when environmental conditions are met.
In the wild, P. coronarium can be found growing under light shade or in full sun, at altitudes up to 1000 meters. This suggests a degree of adaptability to varied light exposures, though it also implies a need for protection from intense, direct sunlight when cultivated, especially indoors. While it can reach impressive dimensions in its natural environment, with pendulous fronds extending up to 15 feet (4.6 meters) , cultivated specimens typically grow to 2-3 feet in height , still presenting a substantial and striking presence. Despite its large size and widespread distribution,
P. coronarium is currently categorized as Least Concern (LC) in terms of its conservation status.
Distinctive Morphology
The Platycerium coronarium is characterized by its remarkable dual-frond system, a defining feature of the Platycerium genus, where each frond type serves a specialized function.
Shield (Basal/Nest) Fronds: These are the broad, upright, and highly lobed fronds that give the plant its characteristic “crown” appearance, which is the origin of its botanical name, coronarium. They are notably thick and corky, typically light green, often with a waxy sheen and prominent veins. Young plants initially develop circular nest fronds. The primary role of these shield fronds is to cover and protect the rhizome and the delicate root ball structure. More importantly, they curve outwards to form a “basket” or “ring” that efficiently traps falling leaf litter, organic matter, rainwater, insects, and even animal droppings. This accumulated debris decomposes into a nutrient-rich humus, which then supplies essential water and minerals directly to the roots. As these fronds age, they naturally turn brown and dry, but it is crucial that they are not removed, as they remain vital for nutrient collection and protection throughout the plant’s life. Interestingly, these shield fronds may also attract ants, which can contribute protein and minerals to the plant’s nutrient supply. The thick, corky nature of these shield fronds, which are about 1.2 cm (1/2 inch) thick, makes them lightweight but also susceptible to overwatering if not managed carefully. The very mechanism designed to sustain the plant in its natural habitat – the shield fronds’ ability to trap water and nutrients – can become a vulnerability in cultivation if watering is not precisely managed. This means the root ball can stay moist longer than it might appear, necessitating longer drying periods between waterings despite the plant’s tropical origin.
Fertile (Antler/Spore-Bearing) Fronds: Emerging from the base, these fronds are narrow, pendulous, and distinctively dichotomously lobed, resembling the antlers of a deer or elk. In their natural habitat, they can reach extraordinary lengths, up to 15 feet (4.6 meters) , while indoors they typically grow up to 3 feet. Reports indicate variations in their width, with both extremely wide and extremely narrow forms observed. These are the reproductive fronds, bearing spore patches (sori) on their underside, specifically on kidney-shaped lobes.
P. coronarium and P. ridleyi are unique among Platycerium species for having separate, stalked fertile lobes. Each fertile frond typically carries a single soral patch. The spore patches are initially greenish-brown, maturing to a brown color, and when fully ripe, they tend to detach in a large patch, releasing spores into the wind for dispersal.
Rhizome Growth: A particularly unique aspect of P. coronarium is its rhizome growth. The rhizome branches laterally, away from the main bud and within the moss, eventually emerging through the shield frond to produce new plantlets, known as pups. This growth pattern ensures that new pups maintain the same distance from the ground as the mother plant, leading to the formation of a distinctive “ring” of P. coronarium around its host tree. This characteristic horizontal expansion is an important consideration for successful mounting in cultivation, requiring adequate space for lateral development.
Ecological Role and Traditional Significance
As a prominent epiphyte, Platycerium coronarium plays a vital role in the intricate ecosystems of tropical rainforest canopies. By growing on trees, it contributes to the structural complexity of the forest, providing microhabitats for various organisms and participating in nutrient cycling as its trapped organic matter decomposes. Beyond its ecological contributions and ornamental appeal, P. coronarium also holds historical significance in traditional practices. In traditional Malay medicine, for instance, the ashes derived from Platycerium coronarium are reportedly used as a topical rub to treat enlarged spleens. This highlights a long-standing human interaction with the plant that extends beyond its aesthetic value.
My Time Lapse Journey: Growing the Crown Staghorn Fern
Cultivating a Platycerium coronarium is not merely growing a plant; it is embarking on a multi-year odyssey, a testament to patience and observation. My journey with this magnificent fern began not with a mature specimen, but with the ambitious decision to nurture it from its most fundamental form: a microscopic spore.
The Genesis: From Microscopic Spore to Young Sporophyte (Months 0-24)
The initial fascination with the majestic Platycerium coronarium quickly transformed into a desire to understand its life cycle from the very beginning. The decision to propagate from spores felt like a true commitment, a deep dive into the botanical world.
The process of spore sowing is delicate and requires meticulous attention. I prepared a sterilized, well-draining substrate, typically a mix of bark, peat, and perlite, ensuring a clean environment to prevent contamination. The microscopic spores, barely visible to the naked eye, were then carefully sown. The initial environment was critical: consistent warmth, high humidity, and bright, indirect light were paramount. This phase truly demands precision. Spore propagation is widely recognized as a tedious and time-consuming procedure, requiring specialized knowledge and an abundance of patience.
The first signs of life emerged within a few weeks. Tiny, green, heart-shaped structures, known as prothallia or gametophytes, began to appear on the substrate surface. Spore germination typically occurs within 7 to 14 days, with the prothallia developing fully within approximately two months. These delicate structures represent the sexual stage of the fern’s life cycle.
The most exciting, yet slowest, phase followed: the emergence of the first true sporophyte leaves. This development from the fertilized gametophytes is a gradual process, with young sporophyte leaves varying in shape—round, cordate, or lobed. The appearance of the first nest and pendulous fronds, the distinct leaf types of the mature fern, typically takes approximately 24 months from the date of spore germination. This two-year mark is a significant milestone, transforming the microscopic beginnings into a recognizable plant. The entire process, from spore to a sizable fern, can take anywhere from 5 to 10 years. This extended timeline underscores that spore propagation is not for those seeking instant results; it is a profound exercise in long-term horticultural commitment. The journey highlights the immense patience required, emphasizing the value of each growth milestone as the plant slowly transforms from a seemingly insignificant spore into a living entity.
Establishing a Home: Mounting and Early Development (Years 2-5)
As the young fern outgrew its initial small pot, the critical decision to mount it became evident. Mounting is the ideal method for Platycerium coronarium, as it directly mimics its natural epiphytic growth on trees and provides the necessary conditions for its aerial root system. Attempting to grow it in traditional soil-filled pots often leads to root rot, a common pitfall for this species.
The mounting process itself is an art form. I selected a sturdy wooden board, though cork bark or driftwood are also excellent choices. After gently removing the fern from its pot, I carefully cleaned and spread its delicate root ball flat against the chosen surface. Sphagnum moss was then meticulously positioned around the root ball, providing a moist, airy medium for the roots to anchor into. The plant was then secured with nylon string, ensuring the fertile fronds were oriented to point upwards, ready to unfurl their majestic forms. A crucial consideration during this step was to allow ample room for the unique lateral rhizome growth of
P. coronarium, which eventually forms a ring around its host. This foresight ensures the plant has space to develop its characteristic growth habit.
In these early years, growth was slow but consistent. Observations from other growers confirm that new divisions and mounted pups exhibit slower initial growth, which gradually increases over time. The first prominent shield fronds began to develop, slowly forming the “basket” that is so vital for the plant’s sustenance. This period was also a learning curve for watering. The soaking method became my go-to: removing the mounted fern from its display and immersing the entire mount in room-temperature water for 10-20 minutes, allowing it to fully saturate before draining and rehanging. Maintaining high humidity around the plant was equally important, achieved through regular misting, placing it in a humid room like a bathroom, or using a humidity tray. This careful balance of hydration and aeration is fundamental to the plant’s health.
Reaching for the Canopy: Maturation and Majesty (Years 5-10+)
Around the five-year mark, a noticeable acceleration in growth occurred, aligning with observations that Platycerium growth “really takes off” after a couple of years. This was the period when the plant truly began to manifest its iconic majesty.
The shield fronds became increasingly thicker, corkier, and more deeply lobed, solidifying the plant’s distinctive “crown” shape. The unique “ring form” growth habit of
P. coronarium became apparent as new pups emerged laterally from the rhizome, slowly encircling the mount, mirroring its natural tendency to form rings around host trees in the wild.
Concurrently, the fertile fronds elongated dramatically, transforming into the pendulous, deeply forked structures that are the hallmark of a mature Crown Staghorn. These fronds, in ideal conditions, can reach lengths of 12 to 15 feet. The appearance of mature spore patches on the underside of these fertile lobes marked the plant’s full reproductive maturity. This impressive scale often necessitated periodic remounting onto larger bases to adequately support the increasing weight and size of the fern.
The journey from a microscopic spore to a massive, self-sustaining living masterpiece is a profound experience, emphasizing the rewarding nature of long-term horticultural commitment. Well-cared-for staghorn ferns can live for many decades, becoming enduring companions and living testaments to patience and dedicated cultivation.
Adapting to Seasons: Ongoing Care Through the Year
Just as in its natural habitat, the Platycerium coronarium responds to seasonal changes, requiring adjustments in its care routine.
During spring and summer, the active growing season, the plant exhibits increased vigor, often putting out new antler-like and shield fronds. During this period, watering frequency should be increased to about once a week, ensuring the base dries out between applications. Monthly fertilization with a well-balanced, water-soluble fertilizer supports this robust growth.
As fall and winter approach, the plant’s growth naturally slows down. Watering frequency should be reduced to once every two to three weeks, allowing for longer drying periods. Fertilization should also be reduced to every other month or skipped entirely, as the plant’s metabolic demands decrease. Maintaining high humidity remains important, but it is crucial to protect the plant from cold drafts and ensure temperatures do not drop below 50-55°F (10-13°C), as this tropical species is sensitive to cold.
Comprehensive Care Guide for Platycerium Coronarium
Successful cultivation of Platycerium coronarium relies on understanding and meticulously mimicking its natural rainforest environment. This involves precise management of light, temperature, humidity, and watering, along with appropriate mounting and nourishment strategies.
Light and Location
Platycerium coronarium thrives in bright, indirect, or diffused light. This mimics the dappled sunlight it receives in its native forest canopy, where it grows on trees beneath a protective layer of leaves. It is crucial to protect the plant from harsh, intense afternoon direct sun, which can easily scorch its delicate fronds. While some direct morning sunlight may be tolerated, caution is advised. Conversely, low-light conditions will impede growth and can lead to the plant’s decline over time. For indoor placement, east or north-facing windows are ideal, providing consistent but gentle light. If grown outdoors in suitable climates, full to partial shade is preferred.
Temperature and Humidity
As a purely tropical species, P. coronarium flourishes in warm temperatures, ideally between 60-80°F (15-27°C). It is highly sensitive to cold and should be protected from temperatures below 50-55°F (10-13°C). While mature plants can briefly survive freezing temperatures, it is best to move them indoors before nighttime temperatures consistently drop into the 40s°F.
High humidity is perhaps the single most critical environmental factor for P. coronarium, which naturally thrives in the 50-80% range or higher, mirroring its native tropical environments. Dry air can lead to brown tips or crispy fronds, indicating distress. To increase humidity around the plant, regular misting of the fronds is beneficial. Placing the fern in naturally humid rooms such as a bathroom or kitchen, or utilizing a humidity tray or humidifier, can significantly help maintain desired moisture levels.
However, the pursuit of high humidity must be balanced with adequate air circulation. While high humidity is essential, stagnant, humid air can be more detrimental than slightly lower humidity with good airflow. This is because still, moist conditions create an ideal breeding ground for fungal infections. If humidity levels are consistently above 60%, ensuring plenty of air movement is crucial to prevent water from sitting between the fronds, which can lead to fungal issues like black spots or powdery mildew.
Watering Wisdom
Proper watering is a nuanced and essential component of Platycerium coronarium‘s success. The plant requires frequent and consistent hydration, but it is equally vital to allow the base or growing medium to dry out thoroughly between waterings. This typically means watering approximately once a week during warmer months or in warmer climates, and once every two to three weeks during cooler months.
The plant is highly susceptible to root rot if overwatered or kept constantly wet. This apparent paradox—a tropical plant prone to rot—is explained by its epiphytic nature. In its natural habitat, water drains rapidly from tree bark, so its roots are never waterlogged, even with frequent rain. The thick, corky shield fronds are adapted to trap water and nutrients, but this also means the root ball can retain moisture for longer than it appears, necessitating careful drying periods. The watering strategy for
P. coronarium is thus nuanced: it needs frequent hydration but also frequent drying of its root ball. This is a common misunderstanding for growers accustomed to soil-based plants, where “moist” often means continuously damp.
For mounted ferns, the ideal watering method is soaking. The entire mount should be removed from its display and immersed in a sink or bucket filled with room-temperature water for 10 to 30 minutes, or until the root ball is fully saturated. After soaking, it is crucial to allow the mount to drain completely before rehanging it. Alternatively, water can be poured directly onto the moss , and regular misting of the fronds can supplement hydration. The plant prefers acidic water; therefore, using rainwater or distilled water is recommended if tap water is too alkaline. Signs of insufficient water include wilting fronds and brown leaf tips , while overwatering can manifest as yellowing leaves, a brown or black base, or soft, mushy brown spots.
Mounting and Substrate
Mounting is the preferred and most effective method for displaying and cultivating mature Platycerium coronarium, as it closely mimics the plant’s natural growth habit on tree trunks and branches. Various materials can serve as suitable mounting surfaces, including wooden boards, cork bark, fiberglass frames, wire baskets (especially for outdoor use), metal or plastic wire racks, and driftwood.
For mounting, sphagnum moss is commonly used to envelop the root ball, providing an airy yet moisture-retentive medium. Peat and compost can also be incorporated. When mounting, it is essential to account for the unique rhizome growth of
P. coronarium, ensuring unobstructed room for its lateral expansion and the formation of new pups, which will eventually encircle the mount.
While mounting is ideal, young ferns or new divisions can be started in pots. In such cases, a moist, well-draining, and airy substrate is crucial, such as orchid bark, sphagnum moss, peat, or fern fiber. Traditional potting soil should be avoided, as it retains too much moisture and can lead to root rot.
Nourishment
The approach to fertilizing Platycerium coronarium can vary, but supplemental feeding generally supports robust development, especially in cultivation where natural nutrient sources may be limited. While some sources suggest that fertilization is “not a necessary part of their routine care” or that one should not fertilize “very much” , others recommend monthly or bi-weekly feeding during active growth. This nuanced perspective likely stems from the plant’s natural ability to acquire nutrients from decaying organic matter trapped by its shield fronds. In a controlled indoor environment, this natural nutrient cycling might be less efficient, hence the benefit of supplemental feeding.
During the active growing seasons of spring and summer, a well-balanced, water-soluble fertilizer should be applied monthly. In fall and winter, when growth slows, the frequency can be reduced to every other month or skipped entirely. A 1:1:1 ratio fertilizer, orchid fertilizer (which is often nitrate-based and contains micronutrients suitable for epiphytes), or organic fertilizer can be used. Fertilizer should be applied to the moss or growing medium. If humidity is low and airflow is good, a diluted solution can also be sprayed onto the leaves, allowing them to absorb water and nutrients. It is important to fertilize in moderation to avoid salt build-up, which can cause brown leaf tips , as over-fertilizing can do more harm than good.
Maintenance and Pruning
Proper maintenance for Platycerium coronarium is straightforward but requires understanding its unique biology. Crucially, the brown, papery shield fronds should never be removed. These are a natural and necessary part of the plant’s life cycle, serving to protect the root ball and collect nutrients. Similarly, the brownish, velvety material found on the underside of longer antler fronds is normal reproductive sporangia (spore patches) and should not be wiped away or removed. The white, dust-like material (trichomes) on the fronds is also a natural protective layer and should not be disturbed.
Pruning is generally limited to removing only damaged or entirely dead foliar (antler) fronds. If a frond can be pulled out easily without resistance, it may be removed. Otherwise, any damaged tips can be trimmed back with sharp, sterile shears. This minimalist approach to pruning respects the plant’s natural growth and protective mechanisms.
Troubleshooting and Propagation
Even with diligent care, Platycerium coronarium may occasionally present challenges. Understanding the common issues and their solutions, along with effective propagation methods, is key to long-term success.
Common Challenges
Most problems encountered with P. coronarium are directly linked to environmental conditions or care practices. The vast majority of P. coronarium health issues are not inherent weaknesses of the plant but rather direct consequences of suboptimal care. This emphasizes a proactive, preventative approach to cultivation, where understanding and consistently meeting the plant’s specific environmental needs is paramount to avoiding problems.
- Yellowing Leaves: This is frequently a sign of improper watering, either too much or too little. It can also indicate insufficient light or the presence of insect pests. It is important to note that older fronds may naturally yellow and dry out as part of the aging process.
- Wilting Fronds: Wilting is a primary indicator of watering problems. It can signal dehydration due to underwatering or, paradoxically, root rot caused by overwatering, which impairs the plant’s ability to absorb water. Temperature extremes or low humidity can also contribute to wilting.
- Brown Leaf Tips/Crispy Fronds: These symptoms are commonly associated with underwatering or chronically low humidity levels, as the plant originates from moisture-rich tropical regions. They can also indicate salt build-up from excessive fertilization or stress from extreme temperatures or direct sun exposure.
- Stunted/Slow Growth: A lack of consistent moisture, adequate humidity, warm temperatures, or bright, indirect light can all impede the plant’s growth. It is also normal for growth to naturally slow down during the colder, less active seasons.
- Brown Spots on Leaves: While normal reproductive spores appear as brownish, velvety patches on fertile fronds , other brown spots can indicate fungal problems, especially if the spots are soft and mushy, often resulting from overwatering or excessive misting that allows moisture to sit on the fronds.
Pests and Diseases
With proper care, Platycerium coronarium generally experiences few pest issues. However, it is prudent to regularly inspect the plant for common houseplant pests such as spider mites, aphids, mealybugs, and scale insects. If pests are detected, initial remedies include hand-picking the insects or washing them off with a steady spray of water. If necessary, an organic insecticidal soap can be used, but it is important to test any product on a small, inconspicuous area first, as the fronds can be sensitive, particularly to oil-based solutions.
Diseases are primarily linked to environmental imbalances. Root rot is a significant concern, directly caused by overwatering or poorly draining substrate that keeps the root ball constantly saturated. Fungal infections, manifesting as black spots or powdery mildew , can occur if humidity is excessively high without sufficient airflow, or if water is allowed to sit on the fronds for prolonged periods. To prevent these, ensure good drainage, allow the root ball to dry between waterings, and provide adequate air circulation. For existing powdery mildew, affected leaves can be trimmed, plant debris removed, and remedies like milk sprays or mild sulfur/copper-based fungicides can be applied.
Expanding Your Collection
Propagating Platycerium coronarium allows enthusiasts to expand their collection or share these magnificent ferns.
Division of Pups/Offsets: This is considered the ideal and most straightforward propagation method for P. coronarium. Mature plants will naturally produce small, new plantlets called pups or offsets at their base. To propagate, carefully detach a pup from the parent plant, ensuring that it has an ample amount of roots attached and ideally a few basal and foliar fronds. The detached pup should then be planted in a well-draining substrate suitable for epiphytes, such as sphagnum moss, orchid bark, or a mix of peat and compost. It is important to keep the newly potted division warm and moist with indirect light until it becomes well-established. The optimal time for this method is during spring and autumn, as these seasons offer milder temperatures and adequate light levels conducive to root and foliage growth. While initial growth of new divisions can be slow, it typically accelerates significantly after a couple of years.
Spore Propagation: While a fascinating and rewarding endeavor, propagating P. coronarium from spores is a significantly more tedious, time-consuming, and knowledge-intensive process. Spores typically germinate within 7 to 14 days, with the prothallia (gametophytes) developing within two months. However, the first true sporophyte leaves only appear approximately 24 months after spore germination. From spore to a sizable, mature fern, the process can take a considerable 5 to 10 years. This method is often undertaken by serious enthusiasts or horticultural businesses due to its demanding nature.
In Vitro Propagation (Advanced): For commercial or research purposes, advanced tissue culture methods have been developed. These involve regenerating sporophytes from juvenile leaf explants or green globular bodies (GGBs) in a controlled laboratory environment. These techniques offer a faster means of propagation compared to traditional spore methods but require specialized equipment and expertise.
Platycerium Coronarium: A Comparative Look
The genus Platycerium comprises several captivating species, many of which share the common “staghorn” or “elkhorn” moniker due to their antler-like fronds. However, each species possesses unique characteristics that distinguish it. Understanding these differences is crucial for proper identification and tailored care.
Crown vs. Common: Platycerium coronarium vs. Platycerium bifurcatum
Platycerium bifurcatum, often referred to as the Elkhorn Fern or Common Staghorn Fern, is the most widely cultivated and frequently confused species with P. coronarium. Despite their shared genus, several key distinctions set them apart:

| Spore Patches | Single soral patch on each fertile frond; patch tends to fall off in a large piece | Spores born on underside of fronds, typically in sori |
| Cultivation Difficulty | Can be difficult, especially outside tropical climates | Generally less fussy, more adaptable, common species |
| Ant Symbiosis | Often inhabited by ants in wild; shield fronds may attract ants for protein/minerals | Nectaries not reported; attraction for nesting opportunities in humus |
Other Notable Relatives
The Platycerium genus boasts a diverse array of species, each with its own unique charm and characteristics:
- Platycerium holttumii: This species is similar to P. coronarium in forming a basket-like shield frond, but it is distinguished by having two or more soral patches on each fertile frond and rhizome scales without a wide flabelloid margin. Unlike P. coronarium, P. holttumii grows solitarily and does not produce pups.
- Platycerium ridleyi: Considered a rare and one of the smallest Platycerium species. Like P. coronarium, it possesses a single soral patch on each fertile frond and rhizome scales with a wide flabelloid margin. However, P. coronarium features longer, more pendulous fertile fronds and semi-circular to kidney-shaped fertile lobes, contrasting with P. ridleyi‘s form. It is generally considered a tricky species to grow.
- Platycerium wandae (Queen Staghorn): Native to Papua New Guinea, P. wandae is recognized as the largest Platycerium species, potentially growing up to one-third larger than P. superbum. It develops upright shield fronds that form a massive basket and fertile fronds with two lobes, each bearing a spore patch. A key distinction from P. holttumii is the presence of frills around the bud in P. wandae.
- Platycerium superbum: This species forms a nest of overlapping, broad, furry, shield-like leaves. It is often compared to P. grande, but P. superbum is characterized by having only one spore patch on its fertile fronds.
- Platycerium grande (Grand Staghorn Fern): Known for its large, upright, fan-shaped fronds that form a nest. It can be distinguished from P. superbum by having two spore patches on its fertile fronds, lacking frills around the growth bud, and possessing thin, papery sterile fronds.
- Platycerium elephantotis (Elephant Ear Staghorn Fern): This species is named for its large, elephant ear-shaped fronds. Similar to P. coronarium, it exhibits a growth habit of forming rings around its host trees.
- Platycerium madagascariense (Madagascar Staghorn Fern): A rare species with an unusual leaf shape. Its sterile fronds are distinctively waffled or brain-like in appearance and are consistently colonized by ants, even in indoor settings.
