Description:Species Description - Shrubs to 2 m tall, the stems with minute stellate hairs, long simple hairs (1-2 mm), and a few glandularhairs. Leaf blades up to 13 cm long, almost as wide as long, broadly ovate or shallowly 3-lobed, cordate, irregularly serrate, acuminate, somewhat discolorous, with appressed simple hairs 0.5-1 mm long above and beneath, somewhat more densely pubescent beneath; petioles ¼-2/3 the length of the blade; stipules 4-5 mm long, subulate. Flowers solitary in the leaf axils, the pedicels 3-6 cm long, viscid and with long simple hairs, articulated 5-10 mm below the flowers; involucellar bracts 6-8, irregularly connate below, viscid and ciliate, 12-15 mm long; calyx 15-20 mm long, viscid and ciliate; corolla 3-3.5 cm long, rich purple with a darker center, pubescent on claw, otherwise glabrous; staminal column 12-15 mm long, glabrous, pallid, the filaments 2-4 mm long, purple, the anthers yellowish, sometimes paired; styles emergent from the androecium, almost equaling the petals, glabrous and distally purplish. Fruits 8-9 mm diam., minutely puberulent, subglobose, retuse; mericarps ca. 6 mm long, strongly carinate and reticulate-veined.
Discussion:Illustration. Fryxell (1973: fig. 3).
Pavonia gentryi is distinctive for its irregular involucel and for its richly colored corolla. Its large, showy flowers merit horticultural consideration, if living material could be obtained.
