Anthurium dolichophyllum Sodiro

• Genus: Anthurium
• Botanical Background: The species was described by Luis Sodiro in the 19th century. Sodiro was an influential botanist who contributed significantly to the understanding of South American flora

• Geographical Range: Highlands of Ecuado
• Environment: It prefers humid, tropical climates with consistent rainfall and moderate temperatures. The species typically grows on the forest floor, in rich, well-draining soils that are typically acidic

Leaves

• Leaves of Anthurium dolichophyllum are long, narrow
• Glossy, with a smooth texture
• Grow up to 30 cm in length
• Deep green in color

Inflorescence (Spadix & Spathe)

• The inflorescence is distinctive, featuring a tall, white spadix surrounded by a white spathe. The spathe, unlike some other species in the genus, has a relatively small size and is not highly decorative but contrasts elegantly with the spadix

Growth Habit

• It is primarily terrestrial but can occasionally grow epiphytically in its natural environment. The species has a rhizomatous growth habit and forms clumps over time

Light Requirements

• This species prefers bright, indirect light, although it can tolerate lower light conditions as long as it receives sufficient humidity

Watering & Humidity

• It requires regular watering to keep the soil moist but not waterlogged. High humidity is essential to mimic its natural environment

• A well-draining potting mix that retains moisture is ideal, with a combination of peat, perlite, and orchid bark often recommended for optimal growth

Temperature & Fertilizer

• The species thrives in temperatures between 18-24°C (65-75°F)
• A balanced liquid fertilizer applied every 4-6 weeks during the growing season supports healthy growth
  

Division and Cuttings

• Propagation is typically achieved through rhizome division or by taking stem cuttings with a node. These should be rooted in moist, warm conditions to ensure success

Seeds

• Seeds can be viable if harvested and sown fresh, but germination is slow and requires consistently warm, humid conditions

Typical Issues

• Spider mites and mealybugs
• Overwatering may lead to root rot

Treatment Recommendations

• For pests, neem oil or insecticidal soap can be effective. For root rot, ensure the plant is not waterlogged and consider repotting into fresh soil. Use fungicide if necessary

• Although not widely known outside of the specialist aroid community, this species contributes to the biodiversity of the cloud forests it inhabits

• With its elegant foliage and unique inflorescence, Anthurium dolichophyllum is prized for its aesthetic appeal, particularly among collectors of rare aroids

Wild Population Status

• There are no specific conservation concerns for Anthurium dolichophyllum at present, though habitat loss in the Andes may impact its future availability

Market Availability

• This species is considered rare in cultivation and may be difficult to find outside specialist nurseries. However, it is sometimes available through plant exchanges or dedicated aroid societies
