ENDOSPERMIFOLIA Ficus endospermifolia Corner (1960)  SECTION: ERIOSYCEA

 Latin: Refers to the leaf shape as being similar to the leaves of Endospermum a small tree in the Euphorbiaceae, common in secondary forests.

Plant: Medium tree to 25m  found in open areas on mountain slopes often in secondary forest. The leaf is a very distinctive heart shape.

Fig: The large fig 1.5-2.5cm is covered in very short hairs and looks similar to the fig of Ficus brunneoaurata but is slightly larger. The fig ripens from green to yellow brown.

Leaf: A very distinctive large heart shaped leaf which as with many other Moraceae may be lobed when the plant is young.

Sex: Dioecious

Similar species. Ficus eumorpha lives in the same habitat and also sometimes has heart shaped leaves but they are always densely covered in short hairs whereas Ficus endospermifolia leaves are smooth above (glaborous) and an orange red stipule.

Ficus  brunneoaurata  also has an orange red stipule  but has  a leaf shaped like a broad spear blade not a heart as with Ficus endospermifolia. Note that both Ficus aurata and Ficus fulva have pale green stipules not orange red stipules.

Distribution: Confined to the hills and mountains of Sabah from c 500-1,800m., where it is relatively common,. For example it can be easily seen on the road to the summit of Gunung Alab (1,964m) the highest point in the Crocker Range. One of the commonest figs in the forest surrounding Kinabalu Park HQ and along the road to the Timpohon gate. The area around the Kiau Gap (Lumu Lumu) is particularly rich and is the location where G.H, Wood the Conservator of Forests at the time collected the specimen from which J.H. Corner later described the type. There are only two collections south of the Sabah border. There is a record from the summit of Gng Pagon on the border of Brunei and Sarawak (S.47783) and another from Ulu Anap Tatau District in the hills of Sarawak (S.17688).
