Anthurium gracilipedunculatum K.Krause

• Genus: Anthurium
• Botanical Background: Described by German botanist Kurt Krause in 1923 in Notizblatt des Botanischen Gartens und Museums zu Berlin‑Dahlem, this species is known only from the type collection by Macbride in Peru

• Geographical Range: Native exclusively to the lowland rainforests of Peru.
• Environment: Grows as an epiphyte on tree trunks and branches in humid, shaded understories. Thrives where air is moist, temperatures are warm (approx. 18–28 °C), and rainfall is abundant.

Leaves

• Simple, entire, elliptic‑lanceolate blades
• Prominent midrib and coriaceous texture
• Arise alternately along a short stem

Inflorescence (Spadix & Spathe)

• A single, greenish, lanceolate bract beneath the spadix
• Cylindrical spike bearing numerous perfect flowers; likely pale yellow‑green as in congeners
• Insect‑mediated, common among epiphytic Anthuriums

Growth Habit

• Epiphytic herb with a short creeping rhizome
• Aerial roots for anchorage and moisture uptake

Light Requirements

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

Watering & Humidity

• Water when the top of the potting mix begins to dry
• Maintain high humidity (60–80%) via misting or humidifier

Soil & Potting Mix

• A well‑draining epiphyte mix (orchid bark, sphagnum moss, perlite) to mimic canopy conditions

Temperature & Fertilizer

• Keep between 18 °C and 28 °C
• Feed monthly during the growing season with a balanced, dilute fertilizer

Division & Cuttings

• Divide by sectioning the rhizome, ensuring each piece has at least one growth node
• Root stem cuttings in moist sphagnum

Seeds

• Fruits develop into globose berries
• Requires warm, humid conditions and may take several weeks

Typical Issues

• Mealybugs, scale insects
• Root rot if overwatered
  

Treatment Recommendations

• Neem oil or insecticidal soap for pests
• Improve drainage and reduce watering frequency to prevent rot

• Fruits likely attract birds and arboreal mammals, aiding seed dispersal in its native forest canopy
• Rare in cultivation
  

• Prized by specialist collectors for its slender form and rarity

Wild Population Status

• Known only from the type locality; habitat loss in the Amazon may pose future risks

Market Availability

• Occasionally offered by specialty nurseries
• Not widely available in the general trade
