Leaf blades ovate-triangular to hastately lobed, mostly 1.5-3 x 1-1.5 cm, basally cordate (or hastately lobed), dentate, cute, palmately 5-nerved, discolorous, the upper surface evenly stellate-pubescent, the hairs 1 mm diam., the lower surface densely stellate-pubescent, the hairs of variable size; petioles 1-2 cm long, often pilose distally; stipules subulate to filiform, 4-7 mm long. Flowers solitary in the leaf axils, the pedicels 1-3 cm long; involucellar bracts 5, lanceolate or spatulate, 5-6 x 1-2.5 mm, stellate-pubescent (sometimes also setose-hirsute); calyx 5-7 mm long, stellate-pubescent (sometimes also setose-hirsute); corolla 1-1.5 cm long (flowers sometimes cleistogamous).

Discussion:Illustrations. Krapovickas (1977: fig. 3G-H).
Pavonia orientalis is characterized by its relatively narrow involucellar bracts, coupled with minutely pubescent stems and petioles that are often distally pilose. The name indicates its relatively easterly distribution.
