Perennial, erect, much branched herbs; stems, petioles and pedicels densely stellate-hairy. Leaves 3 - 8 x 2.5 - 10 cm, ovate to ovate-rounded, rarely 3 - 5 or 7-lobed, upper leaves sometimes lanceolate, cordate at base, acute at apex, repand-serrate, 5 - 7-nerved at base, midveins with nectaries at base beneath, stellate-pubescent on both surfaces; petioles 1 - 6 cm long; stipules ca 5 mm long, linear, stellate-hairy. Flowers axillary, solitary, ultimately in terminal clusters; pedicels 1 - 5 mm long. Epicalyx cup-shaped, subcoriaceous, segments 5, connate up to middle, 10 - 15 x 5 - 10 mm, strongly nerved and densely stellate-hairy outside, sparsely stellate-hairy inside. Calyx campanulate; lobes connate up to middle, shorter than epicalyx, teeth more or less deltoid, acute to acuminate, densely stellate-hairy outside, sparsely towards apex inside. Petals pink with darker centre, 2 - 3 cm long, oblong-ovoid, densely stellate-hairy towards apical portion outside, glabrous inside. Staminal column 1.5 - 2 cm long.

Notes. Guerke (Bot.jahrb. 6: 368. 1892) placed this species under the genus Urena L. based on the presence of nectaries on nerves of leaves. While, Hochreutiner (Ann. Cons. jard. Bot. Genev. 5: 131. 1901) placed it under the genus Pavonia Cav. as this species lacks glochidia on mericarps. A critical study of all the specimens of this species represented in Indian herbaria showed that it is somewhat allied to Urena lobata L. in having short flowers in axillary or terminal clusters with short pedicels and in shape and size of leaves, but differs from it in having epicalyx segments connate up to the middle and smooth mericarps.
