Shrub or small tree, 2-4 m. high, the young branches and inflorescence-axes more or less densely arachnoid, the hairs mostly stellate, the older branches gla-brate. Leaves with a slender petiole 3-10 cm. long, arachnoid, the blade ovate to broadly ovate, rounded to cuneate at the base, long-acuminate at the apex, ca. 8-15 cm. long and 5-9 cm. wide, the margins irregularly serrate, the serrations often glandular especially near the base, both surfaces rather sparsely pubescent, the hairs mostly stellate, 3-to 7-palminerved, the nervation slightly prominent beneath. Inflorescences usually terminal, the cymes of 1-2 cymules, usually opposite the bracts, these narrowly ovate to narrowly elliptic, the peduncles ca. 4-7 mm. long, the pedicels ca. 3-6 mm. long. Flowers 12-18 mm. long, hermaph-rodite, the sepals 5, narrowly oblong-lanceolate, acute, the appendages ca. 1-1.5 mm. long, 12-1]8 mm. long (the appendages included) and 1.5-2.5 mm. wide, sparsely hirsute to glabrescent without, glabrous within; petals 5, narrowly obovate-spatulate, rounded and subcrenate, 10.5-13 mm. long and 2.5-3 mm. wide, yellow, glabrous except the ciliate base; gonophore ca. 0.7-0.8 mm. long, with 5 distinct suborbicular glands, the urceolus undulate, ciliate and ca. 0.5 mm. long; stamens 20-30, the filaments 7-11 mm. long, glabrous, the anthers ca. 1 mm. long; ovary suborbicular, ca. 1.6-2 mm. long and 2.1-2.5 mm. broad, densely covered with uncinate spinules; styles 8-11 mm. long, glabrous; stigma obscurely parted. Fruit suborbicular, the body ca. 5-6 mm. in diam., glabrescent, the spines very numerous, ca. 200, ca. 4 mm. long, sparsely hirtellous especially near the base, the spinules uncinate, rather easily loculicidally dchiscent, 3-to 5-loculate, each cell 2-seeded; seeds pyriform, ca. 3 mm. long and 2 mm. wide.
