Leaves broadly ovate to rhombic-ovate, about 5-6 cm. long and 4-5 cm. wide, the base rounded or cordate, the tip abruptly acuminate, the serrations very irregular, unequal and blunt, the upper surface coarsely stellate-tomentose, the lower more densely so; petioles about 2.0 cm. long, stout, densely tomentose. Inflorescences axillary, the cymes of 3-4, very rarely 2, cymules, generally condensed, the flowering peduncles very short, 1-2 mm. long, the pedicels 2-3 mm. long. Flowers hermaphrodite, the buds broadly oblongoid, about 9-11 mm. long slightly before anthesis, very slightly constricted near the base, the apical appendages short, about 1 mm. long; sepals broadly elliptical, about 12-13 mm. long at anthesis including the apical appendages, densely tomentose without, glabrescent and greenish within; petals broadly obovate, about 8-9 mm. long, the claw about 2-3 mm. long, densely plumose; gonophore short and stout, about 0.75 mm. long and 1.5 mm. thick, the glands small, spherical; urceolus short, about 0.5 mm. high, distinctly many-lobed, slightly ciliate; stamens about 20, the filaments glabrous; ovary orbicular, about 1.5 mm. long, the spinules about 30, recurved, the style about 3-4 times the length of the ovary, the stigma very briefly 2-fid. Fruit oblongoid, the body about 3-4 mm. in diameter and 5-6 mm. long at maturity, densely stellate-tomentose, 3-loculate, each cell 1-seeded, the spines about 15-20, 6-10 mm. long, densely pubescent with many short spreading hairs; seeds pyriform, 2.0-3.0 mm. long and 1.5-2.0 mm. wide.A
