• Genus: Anthurium
• Botanical Background: Described as a new species in 2004 by Basil Stergios and Laurence J. Dorr in Acta Botánica Venezuelica based on collections from Guaramacal National Park (2,200–2,600 m) in October 2003.

• Geographical Range: Restricted to moist montane and cloud forests of the Venezuelan Andes, primarily in Trujillo and Portuguesa states, at elevations between 1,700 and 2,600 m.
• Environment: Thrives under high humidity in the wet tropical biome, growing terrestrially in humus-rich soils of shaded understories.

Leaves

• Broadly ovate, subcoriaceous to coriaceous
• 50–60 cm or more in length and 30–33 cm wide, with conspicuous secondary veins and pale
• Pustule‑like raphide cells on the abaxial surface

Inflorescence (Spadix & Spathe)

• Peduncle subterete, semiglossy, 45–65 cm long
• Spathe erect, incurved apically, light greenish‑cream to greenish‑yellow, 14–18 cm long
• Spadix exserted beyond the spathe, 15–21 cm long, greenish‑rose‑wine colored

Growth Habit

• TA robust, terrestrial subshrub arising from a short stem with persistent, linear‑loriform cataphylls
• No tubers or climbing habit

Light Requirements

• Bright, indirect light mimicking understory shade
• Avoid direct sun

Watering & Humidity

• Keep substrate evenly moist but not waterlogged
• Maintain 60–80 % relative humidity

Soil & Potting Mix

• well‑draining, airy medium rich in organic matter (orchid bark, peat, perlite)
• pH around 5.5–6.5

Temperature & Fertilizer

• Optimal range 16–22 °C
• A balanced, water‑soluble fertilizer at quarter‑strength every two weeks during active growth

Division & Cuttings

• Best propagated by rhizome or stem division
• Ensure each section has roots and at least one growing point

Seeds

• Can be sown in sterile, moist medium under warm (25 °C)
• Humid conditions; germination may be slow and variable

Typical Issues

• Mealybugs, spider mites, aphids
• Root rot pathogens under poor drainage

Treatment Recommendations

• Insecticidal soap or neem oil sprays for pests
• Improve aeration and reduce watering to prevent fungal issues

• Part of sect. Calomystrium, known for pale raphide spots on leaf undersides and persistent reddish‑brown cataphylls

• Valued for its large, glossy foliage and dramatic exserted inflorescences; rare in cultivation

Wild Population Status

• Endemic to a limited montane range, potentially vulnerable to habitat disturbance

Market Availability

• Rarely encountered outside specialist botanical collections and advanced hobbyist circles
