Bucephalandra filiformis S.Y.Wong & P.C.Boyce

• Genus: Bucephalandra
• Botanical Background: First formally described by S.Y. Wong and P.C. Boyce, two botanists known for their work on Borneo's flora. Its specific epithet, filiformis, refers to its slender, thread-like leaf structure.

• Geographical Range: Native to Borneo, particularly thriving in the island's humid, tropical forests near water sources like streams and rivers.
• Environment: Prefers consistently high humidity levels, well-drained, acidic soils, and moderate temperatures. It typically grows in shaded environments, sheltered from direct sunlight.

Leaves

• Narrow, elongated
• Exhibit a dark green coloration
• Slight glossiness
• Slender, almost thread-like leaves

Inflorescence (Spadix & Spathe)

• With a small spadix surrounded by a spathe
• Coloration and size vary
• Unremarkable in terms of scent and size

Growth Habit

• Terrestrial or semi-aquatic
• Growing along stream beds and moist soil
• Can also be found as an epiphyte in its native habitat, where it anchors itself to rocks or trees

Light Requirements

• Bright, indirect light
• Direct sunlight can burn its delicate leaves
• Best kept in shaded or filtered light conditions

Watering & Humidity

• Consistently moist soil
• High humidity

Soil & Potting Mix

• A well-draining potting mix with added organic matter, such as sphagnum moss
• If growing in an aquarium or water feature, aquatic soil or substrate works well

Temperature & Fertilizer

• Temperatures range from 70°F to 85°F (21°C to 29°C)
• Use a balanced, water-soluble fertilizer diluted to half strength during the growing season

Division and Stem Cuttings

• Dividing clumps or cutting rhizomes
• Make sure each division has at least one node

Seeds

• Less common but possible
• Seeds need to be sown in moist, warm conditions, with a high level of humidity
  

Typical Issues

• Spider mites, mealybugs, and aphids
• Root rot

Treatment Recommendations

• Insecticidal soap or neem oil
• Ensure proper drainage and adjust watering practices
• Fungicide

• Delicate leaf shape and rarity in cultivation
• Unique morphology

• Ability to thrive in aquatic or semi-aquatic environment

Wild Population Status

• Susceptible to habitat loss and overcollection
• Conservation efforts are important to preserve its natural populations

Market Availability

• Rare in the wild
• Available in the plant trade, particularly among collectors of tropical aquatic plants
• Remains a species of interest primarily for specialized growers
