Necepsia Prain

Genus

Angiosperms > Malpighiales > Euphorbiaceae

Characteristics

Dioecious or monoecious trees with a simple indumentum. Buds often perulate. Leaves alternate, petiolate, the petioles often pulvinate and geniculate, stipulate, simple, crenate-serrate to subentire, chartaceous or subcoriaceous, penninerved, sparingly gland-dotted beneath. Inflorescences axillary, solitary or congested, pedunculate or sessile, spicate, racemose or subpaniculate, unisexual or bisexual; bracts rigid, ± scarious. Male flowers shortly pedicellate; calyx closed in bud, ovoid, apiculate, later splitting into 4–5 valvate lobes; petals 0; stamens many, inserted on a globose receptacle, filaments free, anthers with slightly oblique pendulous thecae, apicifixed, introrse, longitudinally dehiscent, connective produced; disc-glands free; pistillode 0. Female flowers subsessile or very shortly pedicellate; sepals (4–)5(–6), imbricate, persistent; petals 0; disc hypogynous, annular or cupuliform, entire or ± crenulate, thick, pubescent or setose; ovary 3-locular, with 1 ovule per locule; styles 3, ± free or connate at the base, bifid and/or bipartite, papillose. Fruit tricoccous, or dicoccous by abortion, dehiscing septicidally into 3 bivalved cocci leaving a columella; endocarp thinly woody. Seeds subglobose, ecarunculate.
