Anthurium gracililaminum Croat

• Genus: Anthurium
• Botanical Background: Described by Thomas B. Croat in 1986 as part of his comprehensive revision of Anthurium in Panama, published in Monographs in Systematic Botany from the Missouri Botanical Garden.

• Geographical Range: Restricted to premontane rainforests along the Fortuna Dam Road in Chiriquí Province, Panama.
• Environment: Thrives under high humidity in humus-rich, well‑draining soils of the forest floor; temperatures are moderate and rainfall is frequent.

Leaves

• Oblong-lanceolate blades measuring approximately 30–50 cm long and 5–10 cm wide
• Dark green above, and glandular-punctate beneath

Inflorescence (Spadix & Spathe)

• Modest and typically greenish‑white
• Spathes are small and non‑showy
• Pollination likely by small flies or beetles as in related species

Growth Habit

• Often grows terrestrially on the forest floor
• May also adopt a pendent epiphytic habit on fallen logs or tree bases
• Stems are slender with short internodes

Light Requirements

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

Watering & Humidity

• Keep the medium consistently moist but not waterlogged
• Water when the top layer dries
• Maintain humidity above 60 percent

Soil & Potting Mix

• A coarse, well‑draining mix (equal parts orchid bark and peat-based potting mix with perlite) to ensure aeration around the roots

Temperature & Fertilizer

• Ideal range: 18–27 °C (65–80 °F)
• Balanced, general‑purpose fertilizer monthly during the active growing season

Division & Cuttings

• Divide at the rhizome, ensuring each section has aerial roots and at least one growing point
• Pot divisions in the same well‑draining mix

Seeds

• Have short viability
• Sow fresh in a fine, moist medium and maintain warm (24 °C) and humid conditions for germination (typically 4–6 weeks)

Typical Issues

• Mealybugs, spider mites, and root‑rot pathogens

Treatment Recommendations

• Insecticidal soap or neem oil 
• Improve drainage and apply a fungicide if root rot appears

• Contributes to the high aroid diversity of Panama and illustrates the specialization of section Porphyrochitonium

• Prized it for its elegant, pendulous foliage and rarity in cultivation
• 
  

Wild Population Status

• Restricted range suggests potential vulnerability to habitat disturbance

Market Availability

• Rare in the trade
•  Typically found only through specialist nurseries or aroid enthusiasts
