Description

Shrub or tree up to 15(—25) m high; Leaves (l-)2-5(-6)-jugate; Inflorescences axillary and pseudoterminal; Petals 0-5, usually unequal, ovate to elliptic, minute to 2 by 1 mm, glabrous or pubescent (usually at the base), not clawed, usually auriculate. Stamens 7 or 8, 3-4 mm long; Fruits (0.8-)l-2(-3) cm long, glabrous; Seeds up to 8(—12) mm long, ellipsoid to globose;

Distribution

Asia-Tropical: India present; Jawa (Jawa present), Burma present, SE Asia present, SW China present, W Malesia up to the line Philippines-Borneo present
From India, Burma, SW China, throughout SE Asia, to W Malesia up to the line Philippines-Borneo-Java.

Notes

1. Many species formerly kept separate are included in M. pentapetalus. Two of these, 'M. endotrichus' and 'M. brachyphyllus', were distinguished by the presence of a hairy endocarp. Further species were differentiated on the variation in the petals. However, the whole range of variation, from 5 well-developed auriculate petals via 5 or less, reduced, non-auriculate ones, to petals absent, occurred in each of these species. Variation in the leaflets led to the description of several more species; ‘M. sumatranus' has leaflets with many pronounced nerves and is common in SE Asia, Sumatra, Borneo, and Luzon; 'M.fuscescens'has leaflets with few, usually less pronounced nerves; it occurs throughout western Malaysia. The variation is extreme in N Borneo and the Philippines; leaflet length: breadth ratio varies here from 2 to 8 ('M. ellipticus' and 'M. salicifolius' resp.), and leaflet sizes range from 5 by 2 cm up to 38 by 15 cm. Collections of the 'salicifolia' type are widespread in the Philippines, while the 'ellipticus' type comes usually from Samar, Leyte, Negros, and northern Mindanao, outside the Philippines being represented also in Indo-China ('M. pentapetalus var. cambodianus'). However, in spite of their variation in flowers and fruits, they are not different from material from India, China, Java, or elsewhere. Notwithstanding all this variation M. pentapetalus is a well-defined species.
