Genus

Angiosperms > Malpighiales > Clusiaceae

Characteristics

Trees or shrubs; sap yellowish, glabrate. Leaves opposite, mostly apically acuminate (Panama) or sometimes rounded, pinnately nerved; stipules wanting. Inflorescences few-flowered cymes or solitary flowers, often condensed, terminal or axillary. Flowers perfect, red or pink; sepals 5, imbricate, the outer 2 smaller; petals 5, contorted, arranged in a globose bud; disc extrastaminal, cupulate; fil-aments forming a column apically separating into 5 parts opposite the petals, each staminal element bearing 2-5 anthers, the anthers linear, dehiscent by lateral slits; ovary 5-locular, the ovules 2-8 per carpel, ascending, the style elongate, peg-like, apically 5-lobed, the stigmas minute, porate. Fruit pink or red, baccate, globose or ovoid few seeded, lacking endosperm, the embryo thick, entire and lacking cotyledons.
More
Medium or large trees, rarely shrubs, with yellowish sap. Leaves opposite or subopposite, with numerous parallel lateral nerves running into a submarginal nerve; secretory canals not very visible.

Disc cupuliform, ± 5-angled, persistent. Stamens joined into a tube surrounding the ovary, divided at the summit into groups of 2–6 anthers, deciduous. Ovary 5-locular, with 1–12 ovules in each locule; styles 5, joined at the base, then spreading-divergent at the apex, persistent. Berries with 1(–3) seeds. Seeds arillate with a thick entire embryo.
Androecium of 5 fascicles of stamens united to form a tube round the ovary and 5 united fasciclodes forming an annulus outside the stamen tube.
