Although Ficus punctata produces the largest fig fruits in Borneo up to 15 cm wide and 18 cm long the leaves are some of the smallest leaves of any fig. Most of the juvenile leaves shown above are 0.5 wide   x 1 to 2 cm long.  Note that the juvenile leaves are highly asymmetrical (unbalanced in shape).

All the leaves shown in this article  are the juvenile (bathyphyll) leaves, apart from the leaves immediately below which are the adult (acrophyll) leaves. The adult leaves are perfectly symmetrical (balanced in shape).

At ground level it is normal only to find the juvenile leaves. Adult leaves are usually only produced high up in the canopy, when the this giant liana starts fruiting.

ABOVE: The introduction to Corners (1939 ) article  in the Bulletin of the Singapore Botanic Gardens on the Section Synoecia  figs of the Malesian botanical region.

At the time Corner was the assistant director of the Singapore Botanic Gardens.  Synoecia figs have since been renamed Section Kalosyce.

Borneo and especially Kinabalu is the world center of  diversity for Section Kalosyce.

At least 17 Section Kalosyce fig species are known from Borneo the majority of which are endemic.

Corner was puzzled  about two particular  features of Section Kalosyce; (1) How they were dispersed  and (2)  The varieties of sizes, shapes and colors  of the very large fig fruits produced by Ficus punctata. which led Corner to describe  Ficus punctata as three different species. These are  (a) Ficus callicarpa (aurantiacea)  for the smaller shiny figs and (b) Ficus punctata  and Ficus barba jovis for the larger more hairy figs.
