Scientific Name:Pavonia dusenii Krapov.
Description:Species Description - Subshrubs 0.5-1 m tall, the stems coarsely stellate-pubescent, the hairs 0.5-1 mm long. Leaf blades sagittate-oblong or sometimes ovate, mostly 1.5-6 x 0.5-2 cm, basally sagittate or cordate, coarsely crenate-serrate, acute, palmately 3-5-nerved, discolorous, stellate-pubescent above and beneath, the hairs ca. 0.5 mm long; petioles 6-18 mm long; stipules subulate, 3-4 mm long. Flowers solitary in the leaf axils, the pedicels 0.5-2.5 cm long, stellate-hirsute, the hairs longer (to 1 mm) distally; involucellar bracts 5-6, lance-ovate, 7-8 x 3-4(-5) mm, hirsute; calyx 8-9 mm long, stellate-hirsute (more coarsely so than involucel); corolla 1.5-2 cm long, pale lavender with purplish center and venation. Fruits 7-9 mm diam., minutely pubescent; mericarps carinate, rugulose, 4.5-5 mm high, basally winged.

Discussion:Illustrations. Krapovickas (1977: fig. 2A-C).

As noted by Krapovickas in his original description, Pavonia dusenii is sufficiently similar to P. guerkeana that the two species are difficult to distinguish. The coarsely hirsute stems and calyces of P. dusenii, however, are notable.
