Ficus heteropleura
尾葉榕
Shrub. Dioecious
Name of the Fig Species
Scientific Name: Ficus heteropleur
General Description
Ficus heteropleura is a fig species that can grow as a small tree or shrub, reaching up to 20 meters in height It often starts life as an epiphyte - germinating on other trees - and may develop into a free - standing tree over time This species is dioeciously, meaning individual trees are either male or female.
The Fig Fruit and Fig Wasp
The figs of Ficus heteropleura are small, stalked, and grow in clusters along the twig. Each fig houses tiny flowers inside, which are pollinated by a specific fig wasp species, Liporrhopalum dubim. This mutualistic relationship is crucial - without the wasp, the fig cannot reproduce, and vice vesa.
Various animals, including birds and mammals, feed on the ripe figs, aiding in seed dispersal throughout the forest.
How It Grows and Attaches
Ficus heteropleura typically begins its life as an epiphyte, growing on the branches of host tees. Unlike "Figs of Shrubs," which are bushy and low - growing, or "Figs of Short Trees," which are small, free - standing trees, Ficus heteropleura can transition from an epiphytic start to becoming a larger tree, depending on environmental conditions.
Typical Habitat in Borneo
While Ficus heteropleura is widespread in regions like the Philippines, Sulawesi, Singapore, and Java, it is relatively scarce in Borneo. In Borneo, it has been recorded in areas such as Long Pasia, Danum, Tabin, Sepilok, and Tawau in Sabah, as well as Lambir, Pulong Tau, and Marudi in Sarawak.
Ecological Role in Borneo Rainforest
Ficus heteropleura plays a vital role in the rainforest ecosystem by providing food for various frugivores - animals that eat fruit - such as birds and mammals. These animals, in turn, help disperse the fig's seeds, facilitating forest regeneration.
Unique Features or Adaptations
- Epiphytic Growth: Starting life on other trees allows seedlings to access sunlight in dense forests.
- Dioeciously Nature: Having separate male and female trees promotes genetic diversity.
- Specialized Pollination: A unique relationship with its specific fig wasp ensures effective palliation.
