Anthurium cylindratum Croat & D.C.Bay

• Genus: Anthurium
• Botanical Background: Described by renowned botanists Croat & D.C.Bay, A. cylindratum has contributed to ongoing discussions in aroid taxonomy. Its discovery and subsequent study highlight significant trends in understanding the diversity within tropical Araceae.

• Geographical Range: Indigenous to the humid lowland and premontane tropical forests of Central and parts of South America, where the climate supports diverse understory flora.
• Environment: Thrives in the shaded, moist understory of tropical rainforests with well-draining, organic-rich soils. High humidity and a consistently warm climate are essential, replicating the conditions of its natural habitat.

Leaves

• Broad and glossy
• Elliptic to ovate in shape
• Exhibit a deep green coloration
• Sometimes accented with subtle vein variegation

Inflorescence (Spadix & Spathe)

• Characterized by an elongated, cylindrical spadix paired with a modestly sized spathe
• Adapted for insect pollination
• The spathe’s pale or muted hues complement the striking form of the spadix

Growth Habit

• Primarily terrestrial, forms clumps and may develop aerial roots in its native humid environment
• Makes it suitable for both indoor collections and specialized greenhouse cultivation

Light Requirements

• Bright, indirect light

Watering & Humidity

• Regular watering is essential to maintain evenly moist soil
• High humidity is vital
• Regular misting or a humidifier can help replicate its natural environment

Soil & Potting Mix

• A well-aerated, peat-based potting mix enhanced with perlite and orchid bark is recommended

Temperature & Fertilizer

• Range of approximately 65°F and 80°F
• Balanced liquid fertilizer every four to six weeks

Seeds

• Possible under controlled warm and humid conditions

Typical Issues

• Spider mites and mealybugs
• Root rot can occur if overwatered

Treatment Recommendations

• For pest control, insecticidal soap or neem oil is effective against most common pests
• To prevent root rot, ensure the potting mix is well-draining and avoid standing water

• The cylindrical spadix is a notable anomaly among its relatives
• Its unique form has prompted further studies in aroid inflorescence morphology

• Highly prized for its unusual architectural form and rarity
• Its elegant structure makes it a standout addition to curated plant collections

Wild Population Status

• While specific population data is limited, habitat loss in tropical regions is a concern
• Conservation initiatives focus on preserving the natural ecosystems where this species thrives

Market Availability

• Typically available only through specialized nurseries and dedicated collectors rather than mainstream outlets
