Anthurium oblongispicum Croat & Grayum

• Genus: Anthurium
• Botanical Background: Described by prominent botanists Thomas Croat and Michael Grayum. Their work has significantly advanced the systematics of the Anthurium genus.

• Geographical Range: Endemic to select areas in South America, likely including tropical lowlands and Andean foothills.
• Environment: Prefers well-draining, acidic soils with consistently high moisture levels; naturally thrives in humid, shaded forest environments.

Leaves

• Oblong in shape with a leathery texture
• Moderately sized with a glossy finish and prominent veining

Inflorescence (Spadix & Spathe)

• Spathe is light-colored, typically creamy or pale green with subtle venation
• Spadix is compact and delicate

Growth Habit

• Primarily terrestrial with a compact, clumping growth form
• Features a shallow root system that may produce aerial roots in high humidity

Light Requirements

• Bright, filtered light mimicking its natural understory conditions
• Avoid direct, intense sunlight that can scorch leaves

Watering & Humidity

• Requires consistent moisture without waterlogging
• Thrives in high humidity
• Regular misting can help maintain optimal conditions

Soil & Potting Mix

• Ideal mix includes peat, perlite, and orchid bark for excellent drainage
• A light, airy potting medium mimics the forest floor environment

Temperature & Fertilizer

• Optimal temperature range is between 65°F and 80°F
• Benefits from a balanced, diluted fertilizer applied lightly during the growing season

Division

• Most commonly propagated by dividing the rhizomes during early spring

Stem Cuttings (if applicable)

• Not commonly practiced with this species

Seeds

• Possible under warm, humid conditions
• Fresh seeds should be sown in a well-draining medium with consistent moisture
  

Typical Issues

• Spider mites and mealybugs
• Root rot can occur if overwatered or kept in poorly draining soil

Treatment Recommendations

• Insecticidal soap or neem oil treatments are effective for pest control
• Ensure proper watering habits and adequate airflow

• Described by renowned aroid experts Croat and Grayum, adding to its scientific intrigue
• Its distinctive leaf shape sets it apart from many other species in the genus

• Highly prized among collectors for its unusual foliage and refined form

• Valued for its ability to adapt well to indoor cultivation in controlled environments

Wild Population Status

• May face conservation concerns due to habitat loss in tropical regions

Market Availability

• Considered relatively rare in the horticultural trade

• Typically available through specialist aroid collectors or botanical institutions
