Scientific Name:Pavonia harleyi Krapov.
Description:Species Description - Shrubs 1 m tall, the stems setose (hairs 2-4 mm long) and densely glandular-pubescent. Leaf blades ovate or triangular, mostly 3-7 x 1.5-3.5 cm, basally truncate, serrulate, acute, somewhat discolorous, palmately 5-nerved, abundantly glandular-puberulent and with appressed setae (0.5-1 mm) on both surfaces;petioles 1-6 cm long; stipules 3-4 mm long, subulate, viscid. Flowers solitary in the leaf axils or sometimes forming paniculate inflorescences, the pedicels 1-2.5 cm long; involucellar bracts 10-12, linear, 6-8 mm long, viscid and ciliate; calyx 7 mm long, ciliate; corolla 2 cm long, white, pale lavender, or yellowish fading lavender, densely white-bearded on claw in a ring at juncture with staminal column; staminal column 1.5 cm long, glabrous, more or less declined and curved with secund anthers, the filaments 1.5-2 mm long; styles exserted, free for distal 3 mm. Fruits 4.5 mm diam.; mericarps subglabrous, ca. 3 mm high, somewhat rugulose.

Discussion:Pavonia harleyi is similar to P. geminiflora in general aspect and differs from it in being more densely viscid, having truncate, narrower leaves, smaller fruits, and rounded mericarps. Differences in mericarp morphology (see Figs. 4, 53) indicate that the two species pertain to different subgenera despite their superficial resemblance. Both species have a horizontal presentation of flowers with a declined staminal column (bearded at the base) and secund anthers— i.e., a slightly zygomorphic flower—which suggests a morphological convergence as a result of a common pollinator syndrome.
