Trees to c. 30 m tall with fluting stems or buttresses. Leaves pinnate or unifoliolate, the leaflets alternate, the most apical on one side appear- ing terminal and often larger; petiolules often swollen; domatia frequently present. Inflo- rescences spikes or basally branched panicles of spikes. Flowers bisexual, yellow. Petals 5, free from each other but united with staminal tube at base. Staminal tube globose to ovoid, with an undulate to toothed margin; anthers 10 in 2 whorls of five, glabrous, the upper ones partly exserted, the lower alternating with the upper and completely included, their connectives extended to form a short acute appendage. Ovary 5-locular, each locule with one ovule; style very short, with a small capitate or pileate, obscurely lobed apex. Fruit a 1–5-seed- ed berry. Seed apparently sarcotestal; embryo with thick plano-convex, superposed, free cotyledons, radicle included.


Asia-Tropical: Lesser Sunda Is. present, N Sumatra present, northern Borneo present, western Ghats of India present
Probably seven species restricted to Indomalesia, one restricted to the western Ghats of India, the rest occurring in Malesia. Three species are fairly widespread, the remaining three, apparently closely related, are rather restricted, one in northern Borneo, one in the Lesser Sunda Islands and the last, undescribed, in N Sumatra


The genus consists of very closely related but clearcut, distinct species, some of which are very little known. It closely resembles Aglaia in pollen and secondary xylem as well as overall facies but it differs in its simple indumentum, the two whorls of anthers with appendages and the 5-locular ovary. It is perhaps closest to Lansium which shares the indumentum and the leaflet form and venation but differs in its single whorl of 10 stamens without appendages, the ramiflorous to cauliflorous inflorescences and the seeds which are arillate and pachychalazal.
