Species Description - Shrubs 1.5-2 m tall, the stems densely covered with purplish glandular hairs 0.5 mm long or less, also with narrow lines of recurved white hairs, sometimes also with scattered simple hairs 1.5-2 mm long. Leaf blades ovate (sometimes slightly lobed), cordate, crenate or serrate, acuminate, mostly 4-13 x 1.5-8 cm, palmately 7-9-nerved, strongly discolorous, minutely puberulent, the lower surface densely and softly puberulent with whitish stellate hairs, the upper surface with simple glandular hairs and scattered stellate hairs; petioles 1-6.5(-8) cm long; stipules 2-4 mm long, subulate. Flowers solitary in the leaf axils (occasionally geminate), sometimes aggregated terminally; pedicels 2-6 cm long, slender; involucellar bracts 5, lanceolate, 7-9 x 1.5-4 mm (sometimes narrower), acute, usually exceeding calyx, densely pubescent with glandular and stellate hairs; calyx 5-8 mm long, ciliate; corolla (2-)3-3.5 cm long, campanulate, pink or rose with a dark center, externally with a few scattered hairs; staminal column 18-20 mm long, glabrous, dark red at base, gradually paler distally, apically 5-dentate, the filaments short (1 mm or less), arranged in ca. 5 whorls, the anthers and pollen yellow; styles exceeding the staminal column, covered with minute white hairs, the capitate stigmas pink, villous. Fruits minutely verruculose, glabrous, 8-9 mm diam., the mericarps 4.5 mm high.

Discussion
The specific epithet is chosen to honor Antonio Krapovickas (b. 1921) of Corrientes, Argentina, cocollector of the type specimen and knowledgeable and productive specialist in the Malvaceae. Pavonia krapovickasii is related to P. hexaphylla and P. vinosa. It is distinguished from the former by the discolorous leaves and from the latter by the fewer involucellar bracts and eciliate calyx.
