• Genus: Holochlamys
• Botanical Background: Described by Adolf Engler in 1905, the genus honors Italian botanist Odoardo Beccari, who first collected the species during New Guinea expeditions.

• Geographical Range: Endemic to the island of New Guinea, especially in Papua province’s montane rainforests.
• Environment: Thrives on mossy riverbanks and waterfall margins at 500–1,200 m elevation, favoring constant moisture, high humidity (>80%), and shaded understories.

Leaves

• Simple, glossy, elliptic to ovate, 10–20 cm long 
• With a smooth texture and conspicuous midrib

Inflorescence (Spadix & Spathe)

• A short white spathe encloses a cylindrical spadix
• Flowers are unscented and adapted for small fly pollinators

Growth Habit

• Terrestrial rheophyte with a short creeping rhizome
•  Roots anchor in rocky substrate near flowing water

Light Requirements

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

Watering & Humidity

• Keep soil consistently moist but well‑draining
•  Maintain high humidity (70–90%)

Soil & Potting Mix

• Use a chunky mix of peat, perlite, and orchid bark to mimic riverbank substrate
• Terracotta or plastic pots with drainage holes preferred

Temperature & Fertilizer

• Ideal range 18–27 °C
• Feed monthly during growing season with a balanced 10‑10‑10 fertilizer at half strength

Division

• Best propagated by dividing healthy rhizomes in spring
• Ensure each section has at least one growing tip

Seeds

• Rarely used
• Seeds germinate slowly in moist, shaded conditions and require sterile substrate

Typical Issues

• Susceptible to root rot from overwatering
• Occasional mealybug or spider mite infestations

Treatment Recommendations

• Improve drainage to prevent rot
• Treat pests with insecticidal soap or neem oil, repeating weekly until resolved

• One of few rheophytic aroids, it has evolved to withstand strong water currents by clinging to rocks.

• Valued for its glossy foliage, compact habit, and rarity in cultivation—popular among advanced houseplant collectors.

Wild Population Status

• Not formally assessed by IUCN
• Habitat disturbance in New Guinea poses potential threats

Market Availability

• Relatively rare but occasionally available through specialty nurseries and aroid societies
