Shrubs 1-2 m. high; older branches glabrous, smooth, punctate with small white lenticels, the younger stems and inflorescence axes rough, generally clothed with many long stellate and simple hairs. Leaves broadly ovate, usually about 14 cm. long and 9 cm. wide, sometimes slightly larger, rounded or cuneate at the base, narrowly and gradually long-acuminate, both surfaces glabrescent or lightly scabrous with short stellate hairs, especially on the nerves; petioles slender, about 6-10 cm. long, usually lightly stellate-pubescent. Inflorescences terminal, the cymes of 1-2 cymules, usually opposite the bracts, the flowering peduncles about 6 mm. long, the pedicels 3-5 mm. long. Flowers hermaphrodite, the buds broadly oblongoid, 14-18 mm. long and 3-4 mm. wide slightly before anthesis, the apical appendages slender, 1-2 mm. long, glabrescent; sepals linear-ovate, 15-20 mm. long including the apical appendages, glabrescent or lightly ferruginous-pubescent without; petals lanceolate to narrowly obovate, subequalling the sepals, the claw 3-5 mm. long, densely plumose; gonophore about 1.5 mm. long and 2.0 mm. wide, the glands spherical; urceolus about 0.5 mm. high, many-lobed, briefly ciliate; stamens 20, the filaments glabrous, smooth; ovary orbicular, about 2 mm. long, the spinules numerous, recurved, the style 14-16 mm. long, the stigma very briefly 3-parted. Fruit lightly pubescent, the body 5-6 mm. in diameter at maturity, rather easily loculicidally dehiscent, 3-loculate, each cell 2-seeded, the spines numerous, about 200, slender, 4-5 mm. long, lightly pubescent at the base, sometimes with few plumose hairs; seeds pyriform, glabrous, about 2-3 mm. long and 1.5-2.5 mm. wide.A
