Anthurium lautum Croat & D.C.Bay

• Genus: Anthurium
• Botanical Background: Described by noted botanists Croat and D.C.Bay, who contributed significantly to the study of Neotropical aroids; their work has helped clarify the relationships and distinct characteristics that separate A. lautum from related species.

• Geographical Range: Native to tropical lowland and montane forests in Central and South America; typically found in regions where dense, humid forests provide ideal growing conditions.
• Environment: High humidity with well-draining, organic-rich soils; flourishes in warm, consistently humid environments, often under the filtered light of the forest canopy, which supports its epiphytic or lithophytic growth habits.

Leaves

• Large, ovate, and glossy
• Prominent venation
• Deep green surfaces and lighter veins
• Texture is smooth, and the margins are slightly undulated

Inflorescence (Spadix & Spathe)

• Spadix surrounded by a delicate spathe
• Spathe may display subtle color variations
• Not notably scented

Growth Habit

• Typically, epiphytic

• May also grow terrestrially when conditions allow

• Develops a rhizomatous root system

Light Requirements

• Bright, indirect light
• Direct sunlight should be avoided to prevent leaf scorch

Watering & Humidity

• Regular watering
• Consistently moist but not waterlogged
• High ambient humidity, ideally above 60%

Soil & Potting Mix

• A well-aerated, organic-rich, and well-draining potting mix
• Incorporate orchid bark or perlite can help 

Temperature & Fertilizer

• Temperatures between 65°F and 80°F (18°C to 27°C)
• Avoid cold drafts
• A balanced, diluted fertilizer applied during the growing season 

Division and Stem Cuttings

• Propagation is achieved through division of the rhizome
• Separate offsets from the main plant during repotting

Seeds

• Less common due to the complex germination requirements and slower growth rates compared to vegetative methods

Typical Issues

• Spider mites, mealybugs, and scale insects
• Root rot or fungal issues

Treatment Recommendations

• Insecticidal soap or neem oil
• Ensure good drainage
• Mild fungicide following manufacturer guidelines 

• Limited distribution and distinctive morphological features
• Contributed to a better understanding of the diversity

• Lush foliage and unique inflorescence
• Rarity and aesthetic appeal make it a standout specimen in curated aroid collections and specialized tropical plant displays

Wild Population Status

• Limited natural distribution and habitat specificity
• May face conservation concerns

Market Availability

• Available through specialized nurseries and botanical collectors

• Remains relatively rare in the commercial market

• Sought after by dedicated enthusiasts and conservation-minded collectors
