Anthurium rotundistigmatum Croat

• Genus: Anthurium
• Botanical Background: Described by the renowned botanist Thomas Croat, whose extensive research on Araceae has been pivotal in understanding the diversity within Anthurium. Its discovery contributed to refining the sectional divisions within the genus.

• Geographical Range: Found in select tropical rainforests, primarily within regions of South America.
• Environment: Thrives in humid, shaded forest understories with well-drained, organic-rich soils; typically grows in areas with stable, warm temperatures and high ambient moisture, characteristic of lowland tropical ecosystems.

Leaves

• Broad, leathery leaves
• A glossy finish
• Deep green color and subtle veining

Inflorescence (Spadix & Spathe)

• A moderately sized spathe and a spadix
• Spathe often displaying a vibrant, contrasting color to the foliage
• Rounded stigmatic surface is a key diagnostic feature, potentially influencing its pollination strategy through specialized insect interactions

Growth Habit

• Primarily terrestrial
• Develops a robust rhizomatous system that supports its growth in the forest floor's competitive environment

Light Requirements

• Bright, indirect light, mimicking the dappled sunlight of its natural understory habitat

Watering & Humidity

• Regular watering that maintains consistently moist yet not waterlogged
• High humidity is crucial, so misting or placement in a humid environment benefits the plant

Soil & Potting Mix

• A well-aerated, organic potting mix enriched with peat, perlite, and orchid bark
• Container with good drainage is essential to prevent root rot

Temperature & Fertilizer

• Favors warm temperatures typically between 65°F to 80°F (18°C to 27°C)
• Balanced, diluted fertilizer applied during the growing season

Division and Cuttings

• Most common propagation technique is through division of the rhizomes
• Careful separation during repotting allows for new plants while preserving the parent’s integrity

Seeds

• Less common due to the specialized germination requirements

Typical Issues

• Spider mites, mealybugs
• Occasional fungal infections in overly damp conditions

Treatment Recommendations

• Organic insecticidal soaps and neem oil
• Ensuring proper watering practices
• Chemical treatments should be used sparingly and as a last resort
  

• Uniquely rounded stigmatic feature sets it apart from many of its congeners, sparking interest in its reproductive biology among researchers
• Occasionally been linked with local folklore celebrating the beauty of rare forest flora

• Collectors prize for its rarity and sculptural appeal
• Unusual inflorescence and lush foliage make it a striking addition to tropical plant collections and indoor gardens

Wild Population Status

• Limited range and specific habitat requirements
• Considered uncommon

Market Availability

• Relatively rare in cultivation
• Often available only through specialist growers and botanical collectors
