ABOVE: This illustration published in Volume 3 of the Tree Flora of Sabah and Sarawak, pg. 265 is labelled Ficus bruneiensis but differs in two respects from the TYPE description by Corner (1960) (1) There is a lateral bract on the side of the fig and (2) The stipule is hairless. Therefore this illustration can only be of Ficus aureocordata which does have lateral bracts and a hairless stipule. The TYPE description of F. aureocordata (also by Corner in 1960) is given below.
AUREOCORDATA Ficus aureocordata Corner (1962) SECTION: ERIOSYCEA
Latin: A golden fig (related to F.aurata) with cordate (heart shaped at the base) leaves.
Habit: A very rare large shrub to 4 m with large spirally arranged large leaves.
Leaves: Large leaves with a cordate base and hairy margin with only 4 to 6 pairs of veins.
Fig: Medium sized sessile orange yellow figs sparsely covered in long hairs with distinctive pointed bracts surrounding the ostiole, usually with one or two bracts on the side of the fig.
Similar Species: Similar to Ficus bruneiensis and Ficus auricoma. Both are very rare figs. See also Ficus diamantiphylla.. All four species are confined to hill forest in Brunei and northern Sarawak and Kalimantan.
Distinguish: This species is unique amongst similar species in the lateral bracts on the side of the fig.
Distribution: Berg (2005) records it as present in western and central Borneo between 1,000-1250m.
Sabah: No records
Brunei: According to Coode et al (1996) there are no records from Brunei.
Sarawak: No records.
Kalimantan: The type was collected on Bukit Raya, Kalimantan by Winkler at 1,250m and described by Corner in the Gardens Bulletin of Singapore (1962). There is also a collection in NATURALIS from Long Barang in East Kalimantan.
Taxonomy: “Though known from a single collection, this is a distinct species, peculiar in retaining the lateral bracts on the fig. It comes in leaf-shape between F. bruneiensis Corner and F. eumorpha Corner but the male flowers ally it with F. aurata Miq. (Corner 1962).
