Anthurium morrisii Croat & O.Ortiz

• Genus: Anthurium
• Botanical Background: Described by botanists Thomas B. Croat and Orlando Ortiz, Anthurium morrisii was named in honor of a person or entity with the surname Morris, likely linked to field contributions or support.

• Geographical Range: Endemic to Colombia
• Environment: Found in humid, shaded forest understories with high rainfall. It grows in loose, organic-rich soils and thrives in high humidity and stable, warm temperatures.

Leaves

• Narrowly elliptic, with smooth margins, glossy surfaces, and a dark green hue
• Typically thin-textured and arch gently from long petioles

Inflorescence (Spadix & Spathe)

• Slender, upright spadix accompanied by a narrow, pale green to whitish spathe
• Inflorescence is subtle and not strongly fragrant. Likely pollinated by small insects

Growth Habit

• Terrestrial or occasionally epiphytic in moist forest settings
• Grows from a short stem with aerial roots in mature specimens

Light Requirements

• Bright, filtered light
• Avoid direct sun to prevent scorching of thin leaves

Watering & Humidity

• Needs consistently moist soil and high humidity (above 70%)
• Allow the top layer of soil to slightly dry before rewatering

Soil & Potting Mix

• Grows best in a loose, well-draining mix such as orchid bark, sphagnum moss, and perlite or coco husk
• Ensure adequate aeration and drainage

Temperature & Fertilizer

• Optimal temperatures range from 20–28°C (68–82°F)
• Feed monthly with a diluted balanced fertilizer during active growth

Division

• Can be propagated via division of basal offsets
• Stem cuttings with aerial rootst

Seeds

• Possible but rarely used due to slower development
• Limited seed availability

Typical Issues

• Mealybugs, aphids, or fungal issues if humidity is too low or ventilation is poor
• Overwatering can cause root rot

Treatment Recommendations

• Treat pests with neem oil or insecticidal soap
• Improve airflow and water only when the medium begins to dry slightly

• Rich endemic flora and represents the diversity of Anthurium species in the Pacific lowland forests

• Prized by collectors for its refined foliage and rare status
• Good choice for terrariums or controlled indoor tropical plant displays

Wild Population Status

• Not assessed by IUCN
• Habitat pressures in Colombia's Chocó region suggest possible vulnerability

Market Availability

• Very rare in cultivation
• Appear in specialty aroid collections or through limited botanical distribution programs
