Anthurium rectinervium Delannay & Croat

• Genus: Anthurium
• Botanical Background: Described by botanists Delannay and Croat, this species is the result of extensive research into tropical aroids and has contributed to a deeper appreciation of Anthurium diversity and its intricate evolutionary history.

• Geographical Range: Native to tropical areas of South America
• Environment: Thrives in shaded, humid understories with well-draining soils and accustomed to warm temperatures and consistent moisture levels, mirroring the conditions of its native forest floor.

Leaves

• Large, elliptical to lanceolate
• Smooth texture and glossy green appearance
• Straight, well-defined venation that creates an elegant pattern

Inflorescence (Spadix & Spathe)

• Exhibiting subtle hues of green or pale white
• Not notably fragrant, the structure is adapted to attract specialized pollinators

Growth Habit

• Epiphyte or as a terrestrial plant with creeping rhizomes
• Allows it to colonize forest floors or attach to supporting structures

Light Requirements

• Bright, indirect light
• Avoid direct sunlight to prevent leaf scorch

Watering & Humidity

• Keep the soil evenly moist with regular watering
• High humidity is essential
• Humidifier or pebble tray in drier conditions

Soil & Potting Mix

• A well-aerated, organic potting mix enriched with components such as peat and perlite
• Mix replicates the loose, rich substrate of its natural forest floor

Temperature & Fertilizer

• Between 65–80°F (18–27°C)
• Balanced, diluted fertilizer monthly during the growing season

Division

• Ensure that each division includes a healthy portion of roots to facilitate successful establishment

Stem Cuttings (if applicable)

• Stem cuttings may also be employed with proper care

Seeds

• Less common for this species due to its slow germination and the need for controlled conditions to ensure viability

Typical Issues

• Spider mites, mealybugs, and scale insects
• Overwatering may lead to root rot

Treatment Recommendations

• neem oil or insecticidal soap
• Ensure good air circulation and avoid excessive moisture

• Straight venation of its leaves sparks interest among both botanists and hobbyists
• Discovery has added valuable insight into the diversity of the Anthurium genus

• Prize this species for its unique foliage and rarity in collections
• Attractive appearance makes it a desirable specimen

Wild Population Status

• Due to habitat loss in some parts of its native range, wild populations may be vulnerable

Market Availability

• Remains relatively rare in the horticultural trade
