Anthurium oxyanthum Croat & D.C.Bay

• Genus: Anthurium
• Botanical Background: Described by renowned botanists Croat and D.C. Bay, this species has drawn attention for its distinct morphological features; historical studies and field research by these experts have helped clarify its position among related aroids.

• Geographical Range: Native to the humid tropical regions of South America; typically found in lowland to mid-elevation rainforests. 
• Environment: Thrives under the canopy of tropical forests. It favors environments with high humidity, well-drained organic soils, and a warm, stable climate with regular rainfall.

Leaves

• Heart-shaped to elliptical
• Glossy, smooth texture
• Pronounced venation

Inflorescence (Spadix & Spathe)

• Compact spadix that supports a moderately sized spathe
• Spathe is often tinged with hints of red or maroon
• Serving as an attractant for specific pollinators

Growth Habit

• Terrestrial species that develops a clumping habit with a rhizomatous system
• Allows it to gradually expand and adapt to the understory conditions of its habitat

Light Requirements

• Bright, indirect light that mimics the diffused sunlight of forest understories

Watering & Humidity

• Regular watering is essential
• Consistently humid environment

Soil & Potting Mix

• Balanced, diluted fertilizer applied during the growing season supports

Division

• Mature clumps can be separated carefully
• Ensuring that each division includes a portion of the rhizome and several healthy leaves

Seeds

• Less commonly used by growers due to variable germination rates

Typical Issues

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

Treatment Recommendations

• Routine inspections and the use of insecticidal soap
• Improving soil drainage and reducing water exposure

• Unique coloration of its spathe and the robustness of its growth have led to interest from both ecological and horticultural perspectives
• Presence in the native rainforest understory contributes to local biodiversity

• Prize for its elegant yet understated appearance
• Makes it a valuable addition to specialized plant collections and indoor tropical garden

Wild Population Status

• Habitat loss and deforestation in tropical areas have raised concerns about the sustainability

Market Availability

• Relatively rare in the commercial market
• Usually available through specialized nurseries and collections
