Anthurium yurimaguense Engl. ex K.Krause

• Genus: Anthurium
• Botanical Background: Described by the noted botanists Adolf Engler and K. Krause, A. yurimaguense has garnered attention for its distinct morphology. Its discovery and subsequent classification have contributed to our broader understanding of aroid diversity in South America.

• Geographical Range: Indigenous to the tropical regions of northern Peru, notably in areas surrounding the city of Yurimaguas. 
• Environment: Thrives in regions with high humidity and stable, warm temperatures; naturally occurs in well-drained, organic-rich soils typical of tropical forest floors, where partial canopy coverage provides filtered sunlight.

Leaves

• Medium to large in size
• Heart-shaped leaves

• Glossy texture and prominent venation

• Vibrant green coloration

Inflorescence (Spadix & Spathe)

• Distinct spathe, often in shades of green to reddish tones, paired with a central spadix
• Not noted for a strong scent; the structure is key to attracting specific pollinators through visual signals and subtle fragrances

Growth Habit

• Typically terrestrial
• Emerges from a rhizomatous base

• Growth habit allows it to spread slowly under natural forest conditions, contributing to its resilience in competitive undergrowth

Light Requirements

• Bright, indirect light

• Direct sunlight may scorch the leaves, while too little light can affect its vibrant coloration and growth

Watering & Humidity

• Regular watering is essential
• Emphasis on maintaining high ambient humidity
• Appreciates a consistently moist substrate without being waterlogged to prevent root rot

Soil & Potting Mix

• A well-draining, organic-rich potting mix is ideal

• Incorporating components such as peat, perlite, or orchid bark ensures proper aeration and moisture retention

Temperature & Fertilizer

• Preferred temperatures are warm and stable, generally between 70°F and 85°F (21°C–29°C)
  
• Balanced, diluted fertilizer to promote healthy growth

Division and Cuttings

• Primary method of propagation is through division of the rhizomes
• Careful separation during repotting allows the plant to produce multiple clumps, each with a viable growing point

Seeds

• Less common due to the species’ sporadic flowering

• Require controlled conditions for germination and may have variable viability

Typical Issues

• Spider mites, aphids, and mealybugs

• Fungal infections like root rot

Treatment Recommendations

• Organic insecticidal soap solutions or neem oil can effectively manage pest populations
  
• For fungal issues, ensure improved drainage and consider fungicidal treatments where necessary, following manufacturer guidelines

• Plays a role in its native ecosystems by attracting specialized pollinators

• Isolated occurrence has also made it a subject of interest among researchers studying tropical plant diversity

• Prized for its rarity and ornamental potential

• Visually striking inflorescence and lush foliage make it a standout specimen in curated tropical collections and specialized botanical gardens

Wild Population Status

• Ongoing interest in monitoring its wild populations due to limited geographic range
• Conservation initiatives in native regions aim to protect its habitat from deforestation and environmental changes

Market Availability

• Occasionally available through specialist nurseries and among aroid collectors
• Considered relatively rare and is not widely distributed in commercial horticulture
