Monstera lamersiana M.Cedeño & A.Hay

• Genus: Monstera
• Botanical Background: Described by botanists M. Cedeño and A. Hay, the species emerged from detailed field research in tropical habitats; its identification underscores the continuing exploration and documentation of biodiversity within the aroid family.

• Geographical Range: Native to tropical regions, likely thriving in the rainforests of Central or northern South America; these regions are known for their high biodiversity and rich vegetation layers.
• Environment: Warm, humid conditions typical of tropical forest understories; favors environments with well-draining soils, dappled sunlight, and high ambient humidity, which help maintain its lush foliage.

Leaves

• Heart-shaped with natural fenestrations
• Vary in size and pattern
• Moderately thick and leathery texture
• Deep green coloration

Inflorescence (Spadix & Spathe)

• Follows the typical aroid structure with a spadix enclosed by a spathe
• Spathe generally exhibits muted hues such as green or cream
• Known for a strong scent

Growth Habit

• Epiphytic climber
• Uses aerial roots to attach itself to supporting structures

Light Requirements

• Bright, indirect light
• Direct sunlight may damage the leaves

Watering & Humidity

• Regular watering
• Keep the soil evenly moist while avoiding waterlogging
• High humidity levels

Soil & Potting Mix

• A well-draining, aerated mix with combining peat, perlite, and orchid bark

Temperature & Fertilizer

• Temperature between 65°F and 80°F

• A balanced, liquid fertilizer applied during the active growing season

Division and Stem Cuttings

• Most common propagation method is through division of the rhizomes or taking node cuttings

Seeds

• Less common in cultivation due to variability and slower growth
• Requires controlled, warm, and humid conditions

Typical Issues

• Spider mites, mealybugs, and scale insects
• Root rot

Treatment Recommendations

• Insecticidal soaps or neem oil

• Ensure proper air circulation

• Avoid excessive moisture 

• Distinctive leaf fenestrations serve as a natural adaptation to its environment
• Plays a role in creating microhabitats in its native forests

• Unusual and decorative foliage
• Rarity and unique climbing habit 

Wild Population Status

• Comprehensive data on its wild population is limited

Market Availability

• Relatively rare in the horticultural trade

• Available through specialist collectors and aroid societies
