Anthurium myosurus Sodiro

• Genus: Anthurium
• Botanical Background: First described by Ecuadorian botanist Luis Sodiro, a pioneering figure in the study of Ecuador’s flora, particularly epiphytic Araceae.

• Geographical Range: Endemic to Ecuador
• Environment: Grows in cloud forests at mid to high elevations, thriving in moss-laden tree canopies with high humidity, stable temperatures, and consistent rainfall.

Leaves

• Very narrow, linear, and grass-like, often measuring 20–40 cm in length but only a few millimeters wide
• Smooth texture and are deep green in color

Inflorescence (Spadix & Spathe)

• Spadix is slender, tail-like, and light-colored, accompanied by a narrow, inconspicuous spathe
• Emits little or no scent and is pollinated by small forest insects

Growth Habit

• Primarily epiphytic, with a thin, climbing stem and wiry aerial roots that anchor it to tree bark or mossy substrates

Light Requirements

• Bright, indirect light
• Sensitive to intense, direct light

Watering & Humidity

• Keep evenly moist with high humidity (75% or higher)
• Allow the substrate to lightly dry between waterings but never fully dry out

Soil & Potting Mix

• Use an airy, epiphytic mix such as sphagnum moss, orchid bark, and perlite
• Good drainage and airflow are essential

Temperature & Fertilizer

• Optimal temperatures range from 18–24°C (64–75°F)
• Fertilize monthly with a diluted balanced fertilizer during active growth

Division

• Propagated via stem cuttings or division of rooted offsets
• Cuttings should include at least one node and an aerial root

Seeds

• Propagation is possible but uncommon in cultivation
• Requires moist, warm, and sterile conditions to germinate successfully

Typical Issues

• Spider mites and aphids
• Root rot can occur with overwatering

Treatment Recommendations

• Use neem oil or insecticidal soap for pests
• Ensure the potting mix drains well and avoid letting water sit around the roots

• Name “myosurus” means “mouse-tail,” referencing the distinctive appearance of the spadix
• Rare example of grass-like foliage within Anthurium

• Valued for its minimalist, elegant form and suitability for terrariums or epiphytic mounts
• Ideal for collectors seeking fine-foliaged species

Wild Population Status

• Not assessed by the IUCN
• Narrow range, it may be vulnerable to habitat disturbance

Market Availability

• Rare in cultivation
• Occasionally available through specialty aroid collectors or botanical institutions with epiphyte-focused collections
