Abstract
Decumbent to erect shrubs or small trees. Leaves alternate, densely set, sessile or shortly petiolate, small, simple, linear to lanceolate, subterete, mostly sclerophyllous, persistent, with brownish mucro-like tip; stipules minute when present; trichomes uniseriate, non-glandular. Inflorescences spike- or head-like when present, terminal or lateral, solitary or in compound clusters. Flowers in inflorescences or solitary on bracteate short-shoots or leafy shoots, mostly small, white, pinkish or yellowish, bisexual, actinomorphic, mainly pentamerous, tetracyclic, mostly (half-)epigynous; sepals (4)5, imbricate, calyx tube often adnate to ovary; petals (4)5, free, imbricate, distinct, sometimes clawed, with conspicuous swellings; androecium haplostemonous, stamens (4)5, filaments free or sometimes adnate to the petals, equal or rarely unequal; anthers dithecal, tetrasporangiate, dorsifixed, versatile in tribe Brunieae, introrse, dehiscing longitudinally; carpels (1)2(–5), stylodia usually 2, simple or bifid, stigmas usually minute; gynoecium coenocarpous, ovaries usually (half-)inferior, (1)2(–5)-locular; gynoecial nectaries of the mesenchymatous type, ovules (1)2–4(–12) in each locule, weakly crassinucellate, unitegmic, anatropous. Fruits mainly dry and 1-seeded, dehiscent or indehiscent. Seeds small, occasionally arillate; endosperm often fleshy; embryo straight, very small.
