Pothos ecclesiae P.C.Boyce, S.Y.Wong & A.Hay

• Genus: Pothos
• Botanical Background: Described in 2020 by Boyce, Wong, and Hay in Webbia (Webbia 75:93). The species epithet honors Alison C. Church, collector of the type material.

• Geographical Range: Restricted to southwestern Borneo, with confirmed collections in West, Central, and East Kalimantan.
• Environment: Occurs in mixed old secondary dipterocarp forests on red clay soils, at elevations of 150–315 m. Thrives under warm, humid, shaded understory conditions.

Leaves

• Chartaceous, drying dull pale brown
  
• Narrowly canaliculate, geniculate apex
• Elliptic to ovate‑elliptic, asymmetric sides; apex long‑acuminate, markedly falcate and apiculate; base subacute to obtuse
• 2 intramarginal veins per side, running parallel to margin

Inflorescence (Spadix & Spathe)

• Blooms solitary or rarely paired on slender peduncles (6–8 mm long)
• Spathe: Ovate, 4–6 × 4 mm; cucullate‑concave, yellow, amplexicaul base
  
• Spadix: Stipitate (stipe 10–11 × 0.9 mm); fertile portion 20–30 × 1.5 mm; zig‑zag axis at each floret insertion; yellow
  
• Florets: 5–8 per spadix, ~2 mm diameter; stipitate with conspicuous receptacle; 6 tepals fused halfway; 6 free stamens; oblong‑pyriform pistil.
  

Growth Habit

• Root‑climbing nomadic leptocaul vine
• Heterophyllous shoot system with orthotropic stems, lateral fertile stems, and cataphyll‑encased flowering shoots
• Adhesive aerial roots; no tubers or rhizomes documented.

Light Requirements

• Bright, indirect light mimicking understory shade

Watering & Humidity

• Keep evenly moist
• High humidity (≥70%) preferred

Soil & Potting Mix

• Well‑draining, rich mix of loam, peat, and coarse bark
• Use containers with drainage holes

Temperature & Fertilizer

• Ideal range 22–30 °C
• Feed monthly with balanced (20-20-20) fertilizer during active growth

Division and Cuttings

• Stem cuttings with at least one node and aerial roots
• Root readily in water or moist medium

Seeds

• Fruit produce small ellipsoid seeds (4–6 × 3–4 mm)
• Germination untested but likely favors warm, moist conditions

Typical Issues

• Spider mites, mealybugs, and root rot if overwatered
• Ensure good air circulation and avoid waterlogging

Treatment Recommendations

• Use insecticidal soap or neem oil for pests
• Apply fungicide or repot in fresh medium for root rot

• Berries reportedly edible and sweet, per collector notes
• Named to honor Alison C. Church’s contributions

• Rare species prized by aroid enthusiasts for its slender, falcate leaves and unique zig‑zag spadix structure

Wild Population Status

• Not yet assessed by IUCN 
• Known from few collections, potential vulnerability due to logging

Market Availability

• Extremely rare in cultivation
• Not commercially available
