Anthurium basirotundum Croat.

• Genus: Anthurium
• Botanical Background: Described by the renowned botanist Thomas Croat, this species reflects ongoing efforts to document and understand the rich diversity within tropical aroids.

• Geographical Range: Native to tropical lowland and montane rainforests of South America, where it thrives in naturally humid and shaded environments.
• Environment: Prefers high humidity and stable, warm temperatures typical of tropical climates.

Leaves

• Large, heart-shaped leaves with a distinctly rounded base

• Deep green coloration with subtle venation 

Inflorescence (Spadix & Spathe)

• Features a glossy, vibrant spathe paired with a central spadix

• Not heavily scented, plays a crucial role in attracting specialized pollinators

Growth Habit

• Typically terrestrial, forming clumps through a rhizomatous root system

• Well-suited for cultivation and a prized addition to collections

Light Requirements

• Bright, indirect light

• Prefers dappled sunlight conditions similar to its forest understory origins

Watering & Humidity

• Requires regular watering to maintain consistently moist soil

• High humidity is essential, but avoid waterlogging to prevent root issues

Soil & Potting Mix

• Thrives in a well-aerated, organic potting mix

• Adding perlite helps mimic its natural, nutrient-rich, well-draining forest soil

Temperature & Fertilizer

• Ideal temperature range is 65°F to 80°F (18–27°C)

• Apply a balanced liquid fertilizer every 4–6 weeks during the growing season

Division

• Propagation is most effectively achieved through division of its rhizomes during spring

• Gently separate clumps, ensuring each has viable roots and at least one growth point

• Can be propagated from stem segments with aerial roots
  

Seeds

• Seed propagation is possible but less common

• Germination can be slow and unpredictable, requiring patience and controlled conditions

  
  

Typical Issues

• Mealybugs, and root rot may occur under conditions of overwatering or poor drainage

Treatment Recommendations

• Insecticidal soap or neem oil

• Improving drainage and practicing moderate watering habits

• Collectors and enthusiasts prize this species for its rare appearance

• Unique leaf morphology distinguishes it

• Rarity and striking visual profile make it a standout in tropical collections

• Valued addition to indoor gardens and specialized botanical displays

Wild Population Status

• Due to habitat loss and environmental pressures, wild populations are limited

• Scarcity has prompted interest in conservation efforts to protect its natural habitat

Market Availability

• Species is considered rare

• Typically found through specialist growers and dedicated plant collectors
