Introduction & Overview
Common and Scientific Names
- Scientific Name: Pothos fractiflexus Joling, J.T.Pereira & Damit
- Common Name: Fractiflexus pothos (informal collector’s name)
Quick Facts
- Origin: Endemic to Sabah, Malaysian Borneo
- Features: Linear to narrowly lanceolate leaves with a firm, coriaceous texture
Taxonomy & Classification
- Genus: Pothos
- Botanical Background: Described in 2020 by Joling, Pereira & Damit in Webbia (75: 96), this species adds to the diversity of Borneo’s aroid flora and honors the fractiflexus (zigzag) appearance of its branching stems.
Natural Habitat & Distribution
- Geographical Range: Endemic to lowland and hill dipterocarp forests of Sabah, Borneo.
- Environment: Thrives under a closed canopy with high humidity (70–90%), well-drained humus-rich soils, and mean annual temperatures of 24–28 °C.
Morphological Characteristics
Leaves
- Linear to narrowly lanceolate, entire margins
- Typically 8–12 cm long and 2–3 cm wide
- Leathery (coriaceous), glossy adaxial surface, paler beneath
Inflorescence (Spadix & Spathe)
-
Greenish spathe, tubular, 3–5 cm long Cylindrical spadix, cream to pale yellow, bearing few sessile florets Pollinationis likely by small Diptera or Coleoptera attracted to faint sap odors
Growth Habit
- An obligate climber with adventitious roots
- Stems slender and branching, lacking tubers, anchored to bark and rock surfaces
Cultivation & Care
Light Requirements
- Bright, indirect light
- Tolerates moderate shade but may develop thinner leaves in low light
Watering & Humidity
- Keep substrate evenly moist but not waterlogged
- Water when the top 2 cm of mix dries. Maintain humidity above 60%
Soil & Potting Mix
- Use a well-draining mix of peat, orchid bark, and perlite
- A moss pole or bark slab supports climbing habit
Temperature & Fertilizer
- Ideal range: 18–30 °C
- Fertilize monthly during the growing season with a balanced, water‑soluble fertilizer at half strength
Propagation Methods
Stem Cuttings (if applicable)
- 5–7 cm segments with at least one node, rooted in water or moist mix
Seeds
- Uncommon
- Viability and germination requirements are not well documented
Common Pests & Diseases
Typical Issues
-
Spider mites, mealybugs, scale
Root rot from overwatering, occasional fungal leaf spots
Treatment Recommendations
Notable Traits & Uses
- Collector’s aroid prized for its narrow, architectural foliage
- Ability to cling to vertical surfaces in terraria and shadehouses
Conservation & Availability
Wild Population Status
- Not yet assessed by the IUCN
- Habitat loss in Borneo poses potential risks
Market Availability
- Rare in cultivation
- Available through specialist aroid nurseries and private collectors
