Adelonema wendlandii (Schott) S.Y.Wong & Croat

• Genus: Adelonema
• Botanical Background: Adelonema wendlandii was first described by Schott and later revised by S.Y. Wong & Croat. It was originally placed in the genus Spathiphyllum before being reclassified to Adelonema, a genus distinguished by its unique floral characteristics.

• Geographical Range: Native to tropical regions of Central and South America, particularly in countries like Panama, Costa Rica, and Colombia. It thrives in lowland and montane rainforests, often in shaded, moist environments.
• Environment: Prefers high humidity, temperatures between 20-28°C, and consistent rainfall. The species is typically found in areas with well-draining soils, including rich, organic matter. It also prefers low to medium light levels, reflecting its forest-floor habitat.

Leaves

• Elongated, lance-shaped leaves with a smooth, glossy texture

• Thick and leathery to the touch

• Can reach up to 30 cm in length

• Deep green coloration, occasionally with faint venation or speckling

Inflorescence (Spadix & Spathe)

• White spathe surrounds a yellow-green spadix

• Inflorescence is subtle and not strongly fragrant

• Insect-pollinated in natural habitats

Growth Habit

• Terrestrial, forming dense, low-growing clumps

• Spreads gradually through a rhizomatic root system

• Typically found on moist forest floors, not epiphytic

  
  

Light Requirements

• Prefers bright, indirect light mimicking its natural understory conditions

• Avoid direct, intense sunlight that can scorch leaves

• Too little light can slow growth

  
  

Watering & Humidity

• Keep soil slightly moist but not waterlogged

• Benefits from high humidity (60–80%) for optimal growth

• Mist leaves regularly or use a humidity tray in dry environments

Soil & Potting Mix

• A well-draining, rich mix with organic content

  (peat, perlite, and orchid bark)

• Good aeration helps prevent root rot

Temperature & Fertilizer

• Thrives between 68–82°F (20–28°C)

• Fertilize monthly with a balanced, diluted liquid fertilizer during spring and summer

Division

• The most common method: divide the rhizome into sections, each with a leaf and its own root system

• Pot each division separately

  
  

Stem Cuttings (if applicable)

• Not always applicable, but can work with species that root easily from cuttings

• Ensure cuttings include both stem and node

  
  

Seeds

• Not commonly used due to viability challenges outside natural habitat

• Requires controlled pollination and patience for germination

Typical Issues

• Common pests include spider mites, aphids, and mealybugs

• Root rot can develop if overwatered or kept in poorly draining soil

Treatment Recommendations

• Treat pests with neem oil or insecticidal soap

• Prevent root rot by ensuring good drainage and avoiding stagnant water

• Named after German botanist Hermann Wendland, known for his work on tropical plants

• Leaves are admired for their aesthetic appeal and adaptability to low-light environments

• Prized in ornamental horticulture for its unique foliage and ease of care in shaded spaces

• Makes an excellent houseplant, bringing tropical vibes to indoor environments

Wild Population Status

• Specific conservation data for A. alatum is not widely documented, but habitat loss in tropical forests remains a concern

Market Availability

• Occasionally available through specialty aroid nurseries and collectors
• May require some searching or importing for those outside its native range
