Ayuantha evelyniae (P.C.Boyce & S.Y.Wong) S.Y.Wong & P.C.Boyce

• Genus: Ayuantha
• Botanical Background: Studied and named by renowned botanists P.C. Boyce and S.Y. Wong.

• Geographical Range: Native to tropical regions, primarily within humid lowland rainforests and occasionally in transitional forest zones.
• Environment: Thrives in warm, humid conditions with rich, well-draining soil. Typically experiences high humidity, moderate to high rainfall, and filtered light under the forest canopy.

Leaves

• Large, with an elliptical shape and pronounced veining
• Glossy texture and a deep green coloration

Inflorescence (Spadix & Spathe)

• Brightly colored spathe that contrasts with the darker spadix
• Spathe can be a focal point in cultivation due to its size and subtle fragrance that aids in attracting specific pollinators

Growth Habit

• Typically grows as an epiphyte or terrestrial plant
• Develops a robust rhizome system that supports its upward growth habit

Light Requirements

• Flourishes in bright, indirect light
• Direct sunlight may scorch the leaves, so filtered or dappled light is ideal

Watering & Humidity

• Regular watering is essential
• Keeping the soil evenly moist but not waterlogged

Soil & Potting Mix

• A well-draining potting mix enriched with organic matter
• A mix that includes peat, perlite, and orchid bark can support healthy root development

Temperature & Fertilizer

• Ideal temperatures range between 65°F and 80°F (18°C–27°C)
• Balanced, diluted fertilizer applied monthly during the growing season

Division and Cuttings

• Careful separation of clumps in spring can yield healthy new plants

Seeds

• Less common, seed propagation is possible
• Germination typically requires warm, humid conditions and consistent moisture to be successful
  

Typical Issues

• Spider mites, mealybugs, and occasional root rot from overwatering

Treatment Recommendations

• Organic insecticidal soap
• For root rot, improving drainage and reducing watering frequency
• Chemical treatments should be used cautiously following proper guidelines
  

• Holds a special place among aroid enthusiasts due to its recent taxonomic reclassification and distinct floral structure
• Unique morphology has sparked interest in botanical studies and conservation efforts

• Unusual leaf shape and vibrant inflorescence
• Rarity and striking appearance make it a sought-after specimen in both private collections and botanical gardens

Wild Population Status

• While not extensively documented, habitat loss in tropical regions has raised concerns about the sustainability of wild populations

Market Availability

• Relatively rare in the horticultural trade
• May find it through specialized collectors or botanical exchanges rather than in common garden centers
