Description:Species Description - Herbs <1 m tall (?), the stems with fine subarachnoid pubescence. Leaf blades elliptic, basally truncate or subcuneate, sharply serrate, acute or acuminate, penninerved, essentially glabrous, 6-9 x 2-3 cm; petioles 3-6 mm long, evenly stellate-pubescent; stipules 6-8 mm long, subulate or narrowly lanceolate, obscurely pubescent. Flowers solitary in the axils, the pedicels 2-3 cm long in flower, accrescent to 10 cm in fruit, with pubescence like stem but finer; involucellar bracts 6-7, ligulate, 4-5 mm long, obscurely pubescent, more or less reflexed; calyx 4 mm long, minutely pubescent, half-divided; petals 10 x 3 mm, white; staminal column ca. half length of petals, the anthers few (ca. 10), subsessile; styles emergent from the column, slender, the stigmas capitate, reddish. Fruits 8-9 mm diam. (excluding spines), glabrous; mericarps notably reticulate (ligneous?), with 3 stout spines ca. 1 cm long, the central spine erect, the lateral spines divergent, all retrorsely barbed toward apex.
Discussion:Illustrations. Krapovickas (1982b: fig. 1C, pl. 6).
Pavonia stenopetala is characterized by long fruiting pedicels (to 10 cm long) and narrow, ligulate, white petals. Its petals are like those of P. piptocalyx, but its pedicels are much longer.
