Anthurium multisulcatum Engl.

• Genus: Anthurium
• Botanical Background: Described by Adolf Engler, a pioneering botanist in Araceae taxonomy, who named the species for its distinctive multi-grooved leaf surface (“multisulcatum” meaning “many grooves”).

• Geographical Range: Endemic to Ecuador
• Environment: Thrives in moist, shaded environments typical of lower montane or pre-montane cloud forests. Prefers organic-rich soils and consistent humidity.

Leaves

• Oblong to lanceolate, leathery, and prominently sulcate with parallel grooves running lengthwise across the blade
• Dark green and glossy

Inflorescence (Spadix & Spathe)

• Spadix is slender and pale to cream in color, accompanied by a narrow, greenish spathe
• Likely beetle or fly-pollinated

Growth Habit

• Terrestrial or occasionally epiphytic plant, forming tight clumps
• Grows from a short stem and is supported by a fibrous root system

Light Requirements

• Bright, indirect light
• Direct sun should be avoided to prevent leaf burn

Watering & Humidity

• Requires consistently moist conditions and high humidity (above 70%)
• Allow the top layer of soil to slightly dry between waterings

Soil & Potting Mix

• Use a well-draining, chunky mix containing orchid bark, peat, and perlite or pumice
• Soil should retain moisture without becoming compacted

Temperature & Fertilizer

• Ideal temperatures range from 18–26°C (64–79°F)
• Fertilize every 4–6 weeks during active growth with a balanced, diluted liquid fertilizer

Division

• Propagated by dividing clumps or taking stem cuttings with visible nodes and aerial roots
• Maintain high humidity for rooting success

Seeds

• Propagation is rarely used
• Should be sown in moist sphagnum and kept in warm, humid conditions for germination

Typical Issues

• Spider mites, aphids, and mealybugs, especially in dry environments
• Overwatering can lead to root rot

Treatment Recommendations

• Use neem oil or insecticidal soap to treat infestations
• Ensure proper airflow and drainage to reduce the risk of fungal infections

• Nname “multisulcatum” highlights its uniquely grooved leaves
• Distinguishable among other Anthurium type

• Highly sought after by collectors for its deeply textured foliage
• Ideal for display in botanical collections or high-humidity indoor settings

Wild Population Status

• Not formally evaluated by the IUCN
• Restricted native range in Ecuador and habitat pressures may make it susceptible to decline

Market Availability

• Rare in cultivation
• Found in aroid specialty collections or through botanical institutions but not widely offered commercially
