Etymology

The tropical plant genus Willughbeia all commemorate Francis Willughby, English ornithologist and ichthyologist.[3] Edulis comes from the Latin, which translates as edible.[4] In fact, it is one of the rare climbing plants of Southeast Asia of which the fruits are eatable.[5]

Description

It is a yellow sour edible fruit found in: India, Indo-China (Cambodia, Myanmar, and Isan (northeastern) with Chanthaburi Province of Thailand[6] as well as Vietnam) include Peninsular Malaysia. It may be known under a number of synonyms including "Willughbeia cochinchinensis".[7]

After its reddish lenticelled stems are excised, they exude a milky latex which produces a rubber called chittagong.[8] The roots can be used as a red dye[9] and it may be used medicinally in parts of Asia including Cambodia.

Vernacular names

Local names include: kuy (គុយ) in Cambodia; gedraphol, laleng-tenga, bel-tata in India; dton-kuy (ต้นคุย), kuiton (เถาคุย), kreua (เครือ), and katong-katiew (กะตังกะติ้ว) in Thai; bak yang-pa (บักยางป่า) in Isan dialect.[6][9] talaing-no in Myanmar; and guồi in Vietnamese.[10]

Kubal madu in Indonesia refers to a similar edible relative, W. sarawacensis.
