Descripción
Bushy shrubs about 2 m. high; branches and inflorescence axes smooth with many long, spreading, stellate hairs. Leaves narrowly to broadly ovate, 12-15 cm. long and 6-9 cm. wide, the base obtuse to subcordate, the tip narrowly and gradually acuminate, the serrations rather regular, generally glandular, the upper surface lightly stellate-pubescent, the lower more densely and softly so; petioles 5-7 cm. long with long, spreading, stellate tomentum. Inflorescences generally axillary, sometimes terminal, the cymes of 1 cymule, the flowering peduncles about 8 mm. long and the pedicels about 6 mm. long. Flowers hermaphrodite, the buds broadly oblongoid, 6-10 mm. long at anthesis, the apical appendages very slender, 5-7 mm. long, usually spreading, rather densely plumose; sepals oblong, about 12-16 mm. long including the apical appendages, lightly long-plumose without, brownish and glabrescent within; petals obovate, about 3-4 mm. long, the claw about 1 mm. long, lightly plumose; gonophore about 1 mm. long, nearly 2 mm. wide, the glands narrowly elliptical; urceolus rather short, 0.25-0.5 mm. high, distinctly many-lobed, lightly ciliate; stamens about 40, the filaments glabrous; ovary orbicular, about 1.5 mm. long, the spinules about 40, recurved, the style 6-7 mm. long, the stigma acute, sometimes very briefly 2-fid. Fruit orbicular, about 4 mm. in diameter at maturity, very lightly pubescent, usually 3-loculate, sometimes 4- to 6-celled by false-septation, each cell 1-seeded, the spines about 40, straight, essentially glabrous, each about 2 mm. long; seeds pyriform, 2.0-2.5 mm. long and 1.5-2.0 mm. wide.A
