Anthurium parvispathum Hemsl.

• Genus: Anthurium
• Botanical Background: Described by William Hemsley in 1885 in Biologia Centrali‑Americana. Detailed morphological treatment by Thomas B. Croat in his 1983 revision of Central American Anthurium.

• Geographical Range: Endemic to Guatemala (Baja Verapaz, Sierra de las Minas, Suchitepequez) and Honduras (Comayagua, Lempira, Ocotepeque); occasional records in Chiapas, Mexico.
• Environment: Grows epipetrically on rocks in dry forest patches within the wet tropical biome; moderate humidity, well‑drained rocky substrates.

Leaves

• 16–50 cm long, broadly sulcate petiole
• Oblong to lanceolate blade, 27–64 × 6.5–12 cm, subcoriaceous, acute apex, truncate base
• Matte and glaucous on both sides, lower side paler
  

Inflorescence (Spadix & Spathe)

• Lanceolate, green spathe
• Sessile spadix, green to pale yellow, 3.5–9 cm long, bearing 4‑lobed flowers

Growth Habit

• Epipetric subshrub with short stem
• Thick upward‑directed roots, persistent cataphylls
• Lacks tubers

Light Requirements

• Bright, indirect light
• Avoid direct midday sun

Watering & Humidity

• Water when top inch of soil dries
• Maintain humidity above 60% to prevent browning

Soil & Potting Mix

• A well‑draining, coarse mix (orchid bark, perlite, charcoal) in containers with drainage

Temperature & Fertilizer

• 65–85°F (18–29°C)
• Monthly feeding with diluted balanced fertilizer during growth

Division & Cuttings

• Divide clumps or take stem cuttings
• Use rooting hormone and maintain high humidity

Seeds

• Viable for only a few days post‑harvest
• sow immediately in moist medium, germinate in 2–4 weeks at 70–85°F under high humidity

Typical Issues

• Mealybugs, spider mites. aphids
• Root rot in waterlogged media

Treatment Recommendations

• Water sprays, insecticidal soap, or neem oil
• Improving drainage and, if needed, applying fungicidal drench

• Rock‑dwelling habit
• Glaucous lower leaf surfaces often dry whitish
• Named for its relatively small spathe

• Rare in cultivation
• Prized for its distinctive glaucous foliage and epipetric adaptation

Wild Population Status

• Restricted range and habitat specificity may pose vulnerability risks

Market Availability

• Occasionally available from specialist aroid nurseries
• Generally rare in mainstream trade
