TEMBURONG FIG Ficus temburongensis Berg (2012) Rare Borneo endemic
Habit: Small streamside tree to 5m
Leaves: The symmetrical leaves with a relatively long petiole are covered in silky hairs and grow in tufted whorls at the end of the thick twigs. This is similar to the growth form of the small trees typical of Ficus virescens, Ficus cereicarpa, Ficus francisci and Ficus albomaculata which however typically produce bunches of cauliferous figs on the trunk.
Figs: Resemble the typical stoloniferous figs of Ficus uncinata. According to the type collection from Kg Selapon, Temburong, Brunei. “Figs on short branches to 3m long trailing stems from near ground level to c. 2m from ground level. Figs spherical with red brown hairs and green bract like processes.
Taxonomy: In summary Berg’s TYPE description indicates that F. temburongensis appears to the possess the symmetrical leaves and tufted twigs similar to F. cereicarpa and F. francisci (both of which produce cauliferous figs) with a description of the typical stoloniferous geocarpic (earth figs) of Ficus uncinata or Ficus malayana. All these figs can be found in the riverine forest of Temburong, Brunei.
There are only two geocarpic figs in Borneo with symmetrical leaves (F. subterranea and F. beccarii) . In both cases the leaves grow alternately in a flat plane (distichous), not in whorls at the end of bare branches.
