Inflorescences terminal, axillary, rami-, or cauliflorous, rarely sticky. Flowers unisexual, actinomorphic. Sepals 4 or 5 (rarely 3 or 6), free, imbricate, outer 2 (or 1) mostly distinctly smaller, mostly at least inner ones partly petaloid, entire or partly denticulate. Petals 4 or 5 (rarely 3, 6, or 7), shorter to longer than sepals, mostly distinctly clawed; Stamens mostly c. 8 (4-18), in male flowers not to distinctly exserted; Ovary sessile to short-stipitate, lobed or not, 2- or 3(-4)-celled; Ovules 1 per cell, subbasal to median, placenta with an obturator.

Taxonomy

Several genera were combined into Lepisanthes by Leenhouts (l.c.). He subdivided the genus as follows (in brackets the number of species in Malesia):
  • Subgenus Lepisanthes
    • Section Lepisanthes (1)
    • Section Hebecoccus (2)
  • Subgenus Otophora
    • Section Otophora (4)
    • Section Pseudotophora (2)
    • Section Anomotophora (2)
  • Subgenus Erioglossum (2)
  • Subgenus Aphania (3)

Uses

A few species have some value as ornamental trees. The wood of several species is used, but only few reach a sufficient size to have value as timber trees. Different parts of several species are of medicinal value. The fruits of some species are eaten, but only L. fruticosa and L. alata are planted for their fruits.

Notes

Outside Malesia petals may be absent and the ovary may be 1-celled.
