Introduction & Overview
Common and Scientific Names
- Scientific Name: Anthurium ramoncaracasii Stergios & Dorr
- Common Name: No widely used vernacular name has been recorded, and no synonyms are currently recognized
Quick Facts
- Origin: Endemic to the Venezuelan Andes (Trujillo and Portuguesa states)
- Features: Broadly ovate, coriaceous leaves up to 60 cm long; an erect, greenish‑cream spathe, and an exserted, greenish‑rose‑wine spadix
Taxonomy & Classification
- 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.
Natural Habitat & Distribution
- 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.
Morphological Characteristics
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
Cultivation & Care
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
Propagation Methods
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
Common Pests & Diseases
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
Notable Traits & Uses
- 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
Conservation & Availability
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
