Anthurium glanduligerum Engl.

• Genus: Anthurium
• Botanical Background: First published by Adolf Engler in 1905, A. glanduligerum remains anchored in Engler’s monograph on Anthurium. Ongoing phylogenetic revisions continue to refine its infrageneric placement.

• Geographical Range: Endemic to Colombia, with confirmed records in wet tropical biomes.
• Environment: Occurs in humid understory of lowland to lower montane forests, where soil is rich in organic matter and drainage is good.

Leaves

• Lanceolate to elliptic blades, typically 10–20 cm long, with entire margins and a glossy dark green surface
• The epithet “glanduligerum” refers to glandular punctations on the underside

Inflorescence (Spadix & Spathe)

• A small, cylindrical spadix bearing numerous tiny bisexual flowers, subtended by a modest greenish spathe
• Pollination is likely by small flies or beetles, as in related species

Growth Habit

• Terrestrial subshrub with a short erect stem and a rhizomatous base
• Lacks pronounced tubers

Light Requirements

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

Watering & Humidity

• Keep growing medium evenly moist but not waterlogged

• Maintain humidity above 60 percent

Soil & Potting Mix

• A well‑draining, airy mix of orchid bark, peat moss and perlite
• Ensure pots have drainage holes

Temperature & Fertilizer

• Ideal range 18–25 °C, minimum 15 °C
• Feed with a balanced, diluted fertilizer every 4–6 weeks during active growth

Division & Cuttings

• Divide rhizomes or offsets during repotting
• Ensure each section has at least one growing shoot

Seeds

• Viable but slow; germinate best on a moist, sterile medium under warm, humid, and well‑lit conditions

Typical Issues

• Spider mites, mealybugs

• Scale and root rot if overwatered

Treatment Recommendations

• Use insecticidal soap or neem oil for pests
• Improve drainage and reduce watering to combat root rot

• The glandular‑punctate leaf undersides that give this species its name are prized by aroid specialists

• Rare in cultivation, it is sought after by collectors for its understated foliage texture and botanical interest

Wild Population Status

• Not evaluated by the IUCN; likely data deficient given its narrow endemic range

Market Availability

• Rarely found in trade and mainly held in specialist collections
