Scientific Name:Pavonia hotteana Helwig
Description:Species Description - Scandent shrubs, the stems very minutely puberulent. Leaf blades narrowly ovate, mostly 4-6 x 1.5-3 cm (2-2.5 times as long as wide), basally truncate or subcordate, coarsely serrate, acuminate, palmately 5 (-7)-nerved (the sinuses of the principal nerves beneath often webbed at base, forming domatia), slightly discolorous, very minutely puberulent above and beneath (rarely with a few 3-4-armed stellate spicules beneath or simple spicules above), seemingly glabrous; petioles 1-3 cm long; stipules subulate, 1-2 mm long. Flowers solitary in the leaf axils, the pedicels 1.5-2.5 cm long, articulated 3-4 mm below the flower; involucellar bracts 5, lanceolate, 8-12 x 2-3 mm, sometimes marginally ciliate, otherwise glabrous, subequal to or exceeding the calyx; calyx 8-9 mm long, very minutely puberulent; corolla 2.5 cm long, with scattered pubescence externally; androecium exserted by 1 cm, the column glabrous, purplish, 3 cm long, the filaments 5-8 mm long, distally inserted; styles exserted from column, slender, free for distal 8-10 mm. Fruits ca. 6 mm diam.; mericarps carinate and rugulose, minutely puberulent.

Discussion:The frequent presence of domatia in the axils of the principal nerves on the abaxial surface of the leaves is notable in Pavonia hotteana.
