Name of the Fig Species
- Scientific Name: Ficus sinuata (Section: Sycidium)
- Local Names: "Ara" (general Malay term for figs)
- Synonyms: Ficus rostrata, Ficus cuspidata sinuata
General Description
- Growth Form: Sprawling shrub or small tree (up to 6m tall) with drooping branches . Often starts as an epiphyte (growing on rocks/trees) before rooting in soil . - Leaves: Highly variable in shape (oblong, lance-shaped), with wavy or toothed edges and a glossy, corrugated surface . - Sex: Dioecious - Male and female flowers grow on separate plants
The Fig Fruit and Fig Wasp
- Fruit: Small (0.6 - 1.2 cm), ripening orange to dark red, growing in clusters on branches . - Pollinator: Host-specific fig wasps (Ceratosolen spp.) . - Animals that eat figs: Birds (hornbills, fruit doves), squirrels, and bats.
How It Grows and Attaches
- Shrub vs. Tree: Unlike tall strangler figs, F. sinuata grows as a
multi-stemmed shrub with long, straggling branches .
- Adaptation: Can grow as an epiphyte on rocks/trees or root in soil, making it
highly versatile
Typical Habitat in Borneo
- Where: Common in Sarawak and Kalimantan, rare in Sabah except around Mount Kinabalu (900 - 1,500m elevation) . - Habitat: Lowland to montane rainforests, often near forest edges or rocky slopes.
Ecological Role in Borneo Rainforest
- Keystone Species: Provides year-round food for frugivores .
- Seed Dispersal: Birds and mammals spread seeds, aiding forest regeneration.
Unique Features or Adaptations
- Leaf Variability: Leaves can range from smooth to deeply wavy-edged . - Epiphytic Start: Often begins life on rocks or trees before rooting in soil .
