Anthurium remotigeniculatum Croat

• Genus: Anthurium
• Botanical Background: Described by botanist Thomas B. Croat in 1991, published in the Annals of the Missouri Botanical Garden. The epithet “remotigeniculatum” refers to the unusually distant geniculum relative to the leaf blade.

• Geographical Range: Known only from the Peruvian provinces of San Martin and Amazonas.
• Environment: Occurs as a terrestrial or occasional epiphyte in wet tropical forests, typically at mid‐elevations near 530 m. It favors humid conditions with consistent moisture and well‑drained substrates.

Leaves

• Blade shape is ovate to obovate or broadly elliptic

• Size is 27–100 cm long by 14–28.5 cm wide

• Petiole is about 1–34 cm long, 5–10 mm diameter, D‑shaped in cross‑section

• Geniculum is positioned up to 16 cm from the blade

Inflorescence (Spadix & Spathe)

• Linear‑lanceolate, green, 10.5–12 cm long, 0.5–1.5 cm wide spathe

• Spadix is about 10.5–25 cm long, gradually contracted, dark violet‑purple

• Red‑purple, 5.8–6 mm long, 2.8–3.7 mm diameter berries

Growth Habit

• Forms a short‑stemmed rosette
• Internodes 1.5–6 cm diameter
• It lacks prominent tubers but may grow on rock surfaces when epilithic

Light Requirements

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

Watering & Humidity

• Maintain consistently moist (but not waterlogged) soil

• High ambient humidity (above 60 %) is ideal

Soil & Potting Mix

• Use a coarse, well‑draining mix (e.g. 50:50 orchid bark and peat‑based potting media) to ensure air circulation around roots
  

Temperature & Fertilizer

• Optimal range: 65–85 °F (18–29 °C) but avoid temperatures below 60 °F

• Feed weekly during active growth with a high‑phosphorus liquid fertilizer diluted to one‑quarter strength

Division

• Divide mature rosettes or remove side shoots with aerial roots

Stem Cuttings (if applicable)

• Stem cuttings may be rooted in moist sphagnum or coarse mix under warm, humid conditions
  

Seeds

• Possible but slow
• Seeds germinate best in warm (75–85 °F), humid environments and take several years to reach flowering size

Typical Issues

• Mealybugs, spider mites, whiteflies, scale insects, thrips, and aphids
• Inspect new plants and isolate them before introducing to collections

Treatment Recommendations

• Dislodge pests with a strong water spray
• Apply horticultural soap or oil sprays for persistent infestations

• Avoid harsh insecticides that may damage flowers

• The species name highlights its distant geniculum, a rare trait among aroids
  
• Section Pachyneurium is commonly known as “bird’s nest” Anthuriums for their rosette habit
  

• Collectors prize it for its large, architectural leaves and unusual petiole‑blade articulation
• It is seldom seen outside specialist aroid circles

Wild Population Status

• Restricted to a few localities in Peru
• Not currently assessed by the IUCN Red List

Market Availability

• Rare in mainstream trade

• Occasionally offered by specialist aroid nurseries and collectors
