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.
