Anthurium riodocense Nadruz

• Genus: Anthurium
• Botanical Background: Described by botanist Nadruz and collaborators, this species adds to the rich diversity of Anthurium and illustrates ongoing efforts to document and classify tropical aroids.

• Geographical Range: Endemic to Brazil, particularly associated with the Rio Doce region and surrounding tropical forest areas.
• Environment: Thrives in environments characterized by high humidity, well-draining, organic-rich soils, and shaded conditions typical of tropical rainforests.

Leaves

• Broad, heart-shaped
• Glossy texture and delicate venation patterns
• Provide an attractive backdrop to its inflorescence

Inflorescence (Spadix & Spathe)

• A vibrant spathe and a central spadix
• Spathe often displays a deep, rich hue, contributing to its ornamental appeal

Growth Habit

• Grows as a terrestrial species
• Forming clumps with a sturdy rhizome that supports its upright, compact habit

Light Requirements

• Bright, indirect light
• Direct sunlight can scorch the leaves, while too little light may stunt its development

Watering & Humidity

• Maintain consistent soil moisture without overwatering
• High ambient humidity

Soil & Potting Mix

• A well-aerated, organic-rich potting mix that drains effectively is ideal
• An organic-rich, loose medium supports its growth and mimics natural conditions

Temperature & Fertilizer

• Between 65°F and 80°F
• Balanced liquid fertilizer applied monthly during the growing season

Division and Cuttings

• Division of the rhizome or node cuttings
• Carefully separate sections of the plant during repotting to ensure each division has viable roots and a growing tip

Seeds

• Less common due to the lower viability and more specialized germination requirements
• Need a warm and humid environment to germinate successfully

Typical Issues

• Spider mites and mealybugs
• Risk of root rot if overwatered

Treatment Recommendations

• Use mild insecticidal soap or neem oil
• Maintain a careful watering schedule and ensure good airflow

• Named after the Rio Doce region, noted for its unique inflorescence and resilient foliage
• Its discovery underscores the botanical richness of Brazil’s tropical forests

• Prized for its rarity and ornamental appeal
• Its distinctive leaf structure and vivid floral display make it an attractive addition to any tropical plant collection

Wild Population Status

• Faces challenges from habitat loss in its native region
• Leading to ongoing interest in conservation efforts

Market Availability

• Relatively rare in cultivation
• Sought after by dedicated collectors and conservationists
