Anthurium riocojimiesense Croat

• Genus: Anthurium
• Botanical Background: Described by the noted botanist Croat, whose work on the Anthurium genus has been influential in understanding the diversity of tropical aroids. Historical botanical expeditions and herbarium research have contributed to its current classification.

• Geographical Range: Native to select tropical locales, with its distribution often confined to isolated regions in humid, lowland or mid-elevation forests.
• Environment: Thrives in warm, humid conditions with consistently high moisture levels; favors well-draining, organic-rich soils and a climate that supports dense, evergreen vegetation, typically found in tropical rainforest ecosystems.

Leaves

• Broad, leathery
• Display a rich green coloration with prominent venation
• Shape and texture make them visually appealing and functionally adapted to maximize light capture

Inflorescence (Spadix & Spathe)

• Consists of a slender spadix surrounded by a contrasting spathe that may exhibit subtle hues
• Spathe is not highly scented
• Plays a crucial role in attracting specific insect pollinators through its shape and coloration

Growth Habit

• Adopts a terrestrial habit with a well-developed rhizome system, although some closely related species exhibit epiphytic tendencies
• Its compact growth form makes it suitable for container cultivation under the right conditions

Light Requirements

• Bright, indirect light
• Direct sunlight can scorch the leaves, while too little light may stunt its development

Watering & Humidity

• Maintain consistent soil moisture without overwatering
• High ambient humidity

Soil & Potting Mix

• A well-aerated, organic-rich potting mix that drains effectively is ideal
• An organic-rich, loose medium supports its growth and mimics natural conditions

Temperature & Fertilizer

• Prefers warm temperatures typical of tropical climates, with minimal tolerance for cold drafts
• Balanced, diluted fertilizer applied monthly during the growing season

Division and Cuttings

• Division of the rhizome
• Carefully separate sections of the plant during repotting to ensure each division has viable roots and a growing tip
• Node cuttings from established growth can also be used with careful attention to moisture and sterility
  

Seeds

• Less common due to the lower viability and more specialized germination requirements
• Need a warm and humid environment to germinate successfully

Typical Issues

• Spider mites and mealybugs
• Risk of root rot if overwatered

Treatment Recommendations

• Use mild insecticidal soap or neem oil
• Maintain a careful watering schedule and ensure good airflow

• Captured the attention of botanists and plant enthusiasts alike due to its limited distribution and distinct morphology
• Its presence in local folklore and botanical studies underscores its cultural and scientific significance

• Prized for its unusual leaf form and elegant inflorescence
• Its rarity and aesthetic appeal make it a coveted addition to specialized tropical plant collections

Wild Population Status

• Restricted habitat and ongoing environmental pressures
• Considered rare in the wild
• Conservation efforts and habitat preservation are vital for maintaining its natural populations

Market Availability

• Rarely found in commercial trade
• Typically available only through specialized nurseries or from dedicated collectors
• Its scarcity adds to its allure and value in horticultural circles
