Rinorea bengalensis


Growth apparently in flushes, but internodes of equal length. Leaves often distichous. Stipules appressed, triangular, slender, (4-)8-16 mm long, brown and distinctly striate. Inflorescences on the young twigs; Sepals ⅓-½ the length of the petals, rarely as long; Petals strap-shaped and often S-curved, (2½-)3-4(-5) mm long. Ovary sometimes hairy, with 3 ovules, style glabrous. Fruit at the base with the dried striate sepals and petals, before maturity globose, (½-)1-1½ cm ø, with a rest of the style, dull, glabrous. Seeds 3, subglobose, 3-7½ mm, yellow-brown with specks of purple to dull purple all over.

Ceylon, S. India, Assam, Burma, Indochinese Peninsula and Hainan, Andamans, scattered through Malesia (not in S. Sumatra and Java); Northern Queensland, Melanesia, Carolines.


A shrub which may already be fertile when 2 feet tall, to a tree of c. 20 m by 28 cm. Wood yellow, flowers green to white, fruit orange with red seeds, or cream-brown, or pale green. Several records mention the rich green leaves. A very polymorphic species.
As the plant has never been found again in Java after BLUME’S collection from Mts Salak and Burangrang, which was described as Alsodeia paradoxa, I think the record is apocryphous. ZOLLINGER 2979, the type of Pentaloba semigyrata, was from a plant in the Bogor Gardens.
