Anthurium acutangulum Engl.

• Genus: Anthurium
• Botanical Background: Described by Adolf Engler, Anthurium acutangulum has been examined by several botanists over the decades, contributing to a clearer understanding of aroid diversity.

• Geographical Range: Native to the tropical lowland and premontane forests of Central America and northern South America, it is often found in regions with rich biodiversity.
• Environment: Thrives in humid, warm conditions with well-draining, organic-rich soils and filtered light under a forest canopy.

Leaves

• Notably angular with a leathery texture
• Medium to large in size
• Deep green coloration with subtle venation patterns

Inflorescence (Spadix & Spathe)

• Contrasting spathe that can range from shades of red to purple, encircling a spadix that attracts specialized pollinators through its unique structure

Growth Habit

• Typically terrestrial; develops from a robust rhizome
• Upright, allowing the leaves to capture optimal light in dense forest setting

Light Requirements

• Bright, indirect light that mimics its natural dappled forest environment

Watering & Humidity

• Regular watering is recommended
• High humidity is essential for optimal growth
• Ensuring the soil remains consistently moist but not waterlogged

Soil & Potting Mix

• A well-aerated, organic-rich potting mix with good drainage is preferred
• Containers should allow excess water to escape

Temperature & Fertilizer

• Ideal temperature range is between 65°F and 80°
• Fertilize sparingly during the growing season with a balanced, water-soluble fertilizer

Division

• Propagation is most effectively achieved through rhizome division

Stem Cuttings (if applicable)

• Node cuttings may also be used with careful attention to moisture and warmth

Seeds

• Germination can be slow and unpredictable, making vegetative propagation the favored method

Typical Issues

• Spider mites and mealybugs
• Root rot

Treatment Recommendations

• For pest issues, both chemical insecticides and organic treatments like neem oil can be effective
• Maintain proper watering practices helps prevent fungal diseases

• Has captured the interest of both horticultural enthusiasts and botanists due to its unique leaf angles and historical ties to early botanical exploration in tropical America

• Adds a subtle, tropical charm to indoor gardens and specialized aroid collections
• Unusual leaf shape and vibrant inflorescence make it a prized specimen for collectors and indoor gardeners seeking an exotic display

Wild Population Status

• Not currently listed as endangered; habitat loss in tropical regions warrants monitoring of its natural populations

Market Availability

• Moderately available in specialized nurseries and among aroid enthusiasts, though high-quality specimens may be relatively rare
