Abstract
Small, evergreen trees; unicellular lignified T-shaped trichomes present both on vegetative and floral parts. Leaves alternate, opposite or verticillate, simple, petiolate, estipulate, coriaceous, serrate, gland-tipped, venation pinnate-reticulate. Inflorescences terminal, few-flowered, corymbose panicles, the pedicels articulated. Flowers actinomorphic, perfect, the calyx tube short, adnate to base of ovary; sepals 5, persistent, imbricate, the outer ones shorter, the three inner ones enclosing the inner organs in bud; petals 5, imbricate, free, clawed, white, inserted on floral cup; stamens 5, free, antesepalous, alternatingwith disk lobes; anthers dorsi fixed, sagittate, introrse, versatile, opening by longitudinal slits, with a hypogynous 5-lobed disk; gynoecium 5-carpellate; ovary superior to semi-inferior, syncarpous, 5-locular; style simple, apical, hollow; stigma punctiform; placentation axile, ovules 2 per carpel, pendant, collateral, bitegmic, crassinucellar, anatropous. Fruit a few-seeded, loculicidal capsule; seeds 1(2)per locule, large, shiny blackish with a red aril; embryo large, with thick cotyledons and small radicula; endosperm scanty.
