Abstract
Deciduous or evergreen and glabrous small trees or shrubs. Leaves alternate, simple, entire, shortpetioled or sessile, exstipulate. Inflorescences terminal or axillary racemes; pedicels with paired prophylls. Flowers perfect, regular, hypogynous; sepals 5(−7), imbricate, sometimes quincuncially arranged, persistent, the outer larger than the inner, often accrescent in fruit; petals as many as sepals, distinct, imbricate; androecium diplostemonous or (Cyrilla) haplostemonous; anthers dorsifixed, tetrasporangiate, not inverted at anthesis, dehiscing by longitudinal slits; disk intrastaminal, surrounding the base of the ovary; gynoecium syncarpous; ovary (2-)5-locular with axile placentas; style very short or nearly suppressed with lobed stigma or with 2–4 very short stylar branches with apical stigmas; ovules 1–3 per locule (pendulous from near the top of the locule or from a pendulous, stalk-like placenta), anatropous, unitegmic, tenuinucellar. Fruit indehiscent, 1-seeded, dry and drupaceous or samaroid; seed coat completely reduced; embryo slender, straight, with small, slightly expanded cotyledons, embedded in a copious, fleshy endosperm. x = 10.
