Philodendron auriculatum Standl. & L.O.Williams

• Genus: Philodendron
• Botanical Background: Described by botanists Standley and Williams, this species has been of interest due to its distinctive leaf morphology and evolutionary significance among aroids.

• Geographical Range: Native to tropical regions in Central America
• Environment: Thrives under warm, humid conditions with well-draining soils and filtered light, typical of forest understories where moisture and indirect sunlight abound.

Leaves

• Broad, heart-shaped with auriculate bases
• Glossy green surface with subtle lobing

Inflorescence (Spadix & Spathe)

• Slender spadix encased in a greenish spathe
• Adapted to attract insect pollinators without a strong scent

Growth Habit

• Climbing species utilizes aerial roots to ascend supports
• Develops a robust rhizome that aids in nutrient storage and contributes to its vigorous growth

Light Requirements

• Thrives in bright, indirect light

Watering & Humidity

• Keep the soil consistently moist without waterlogging
• Maintain high humidity levels to encourage optimal growth

Soil & Potting Mix

• A well-draining potting mix enriched with organic matter
• Containers that promote air circulation

Temperature & Fertilizer

• Prefers temperatures between 65°F and 80°F
• Balanced, water-soluble fertilizer applied during the growing season

Division and Cuttings

• Most common methods of propagation are through rhizome division and stem cuttings taken from nodes

Seeds

• Seed propagation is possible 
• Less common due to the longer germination period and variable success rates

Typical Issues

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

Treatment Recommendations

• Use organic insecticidal soap for pet control
• Adjust watering practices to mitigate fungal issues
• Chemical treatments should be applied cautiously and as a last resort
  

• Has intrigued botanists for its unique leaf structure
• Sometimes featured in studies of tropical plant evolution

• Holds cultural significance in regions where it naturally occurs
• Prize for its unusual leaf shape and elegant climbing habit

Wild Population Status

• No immediate conservation concerns
• Ongoing habitat loss in tropical areas remains a potential threat

Market Availability

• Available from specialty nurseries and plant collectors
• High-quality specimens may be less common
