Ficus obpyramidata is a fig that grows along rivers in Thailand and Malaya which is occasionally seen for sale in local forest product markets in Sarawak. The large edible  figs are pear shaped and ripen dirty white or greenish.

The closest local fig to F. obpyramidata is Ficus limosa which is a rare Borneo endemic  rheophyte (adapted to growing in flowing water) which has smaller figs but longer thinner leaves.

Edible figs of Borneo

No local figs are eaten ripe in Borneo however a few species are eaten when green either as a starvation food or as a vegetable addition to a sour salad known as ” ulam” – the equivalent of pickles in European cuisine. These figs include Ficus racemosa, Ficus fistulosa and Ficus nota.

Locals only eat unripe female figs NOT male figs.

Two introduced continental Asian figs Ficus auriculata and Ficus obpyramidata  are occasionally grown in home orchards especially in Sarawak  and may also be eaten occasionally  when ripe.

Many locals have tried cultivating the Edible fig of Europe and the Middle East Ficus carica in Borneo but  experiments have shown that they can only be grown in special dry conditions in pots under a roof. Grown outside in the ground they rapidly succumb to fungal diseases.

To add to the confusion Kochummen’s treatment of  Ficus in the Tree Flora of Sabah and Sarawak Vol.3 (2000) listed Ficus limosa as Ficus obyramidata. Some forest botanists in Sabah still refer to Ficus fistulosa as F. obyramidata !

Map Nota from Berg 2005 .jpg
Note that the distribution in this map copied from Berg (2005) shows that F. obpyramidata is not native to Borneo, but it could well have been introduced for growing in home orchards.
