GOLDEN HAIRY FIG Ficus aurata Miq. (1867) SECTION: ERIOSYCEA

Latin: Golden fig

Tree: A small tree with hairy twigs, leaves and figs to 15m very common in secondary forest. Appears to be more tolerant of open and dryer conditions than F. fulva and is often seen along roadsides in open countryside.

Leaf: Very variable in size and shape, often palmate in young plants. The basal side veins run close to the leaf margin not straight at a fixed angle from the base

Fig: A medium size (1.5-2.2 cm) which ripens, green to orange to red. Barbets and bulbuls attack the ripe figs and swallow the small seeds surrounded by a thin pale aril. Male (gall) figs are significantly larger and paler than female figs and fall from the tree uneaten at which time they are coloured a pale yellow with a wide open ostiole.

Sex: Dioecious

Similar Species:

(1) Ficus inaequipetiolata (narrow leaf) used to be considered a morph of Ficus aurata. In Corner’s illustration above the long thin leaf on the left is almost certainly a leaf of Ficus inaequipetiolata not Ficus aurata. 

(2) Ficus fulva which is less common in secondary forest on the edge of towns but more common along the edge of primary forest. The simplest and easiest way to tell the two species apart is by cutting open a fig fruit. The interior of  F. aurata is full of  sharp white hairs. In Ficus fulva, both male and female fig interiors are full of fleshy red tepals- (the bits surrounding the seeds) but no white hairs.

Ecology: The explanation for the difference is probably that Ficus aurata primarily evolved to be dispersed by large grazing mammals such as rhinos and elephants which eat the whole branch  leaves and figs together whilst Ficus fulva evolved to be dispersed by  birds, such as bulbuls that peck the fig open. The reason the fig is hairy externally is to prevent the fruit being swallowed whole by green pigeons which predate the seeds.

Distribution: Common in secondary forest throughout Borneo up to 1,400m, often in the same location as Ficus fulva and Ficus inaequipetiolata.

Range: Malaya, Sumatra, Palawan, Borneo.
