Description:Latin Diagnosis - Frutices, caulibus petiolisque heterotrichibus; laminis foliorum hastatis atque 3-lobis, in superficie Superioris pilis simplicibus curvatis; floribus aggregatis in apicibus; bracteis involucellorum 5, brevi-ciliatis; calycibus 5 mm longis; corollis ca. 1 cm longis, flavidis; fructibus ignotis.
Species Description - Shrubs 1.5 m tall, the stems covered with stellate hairs of two size classes (heterotrichous), the larger 0.6-0.9 mm diam., yellowish, scabridulous, scattered, the smaller 0.2-0.3 mm diam., whitish, densely overlapping. Leaf blades hastately 3-lobed, up to 9 x 7 cm (across basal lobes; the central lobe 2-3 cm wide), basally cordate, serrulate, acute, palmately 7-9-nerved, discolorous, the upper leaf surface with curved simple hairs 0.3-0.6 mm long, the lower surface with stellate hairs ca. 1 mm diam.; petioles 2-5 cm long, heterotrichous like stem, the larger yellowish hairs very dense distally; stipules triangular-falcate, to 7 x 3-4 mm (shorter and wider in the inflorescence), sparsely pubescent. Flowers aggregated at tips of branches, the pedicels 1.5-2.5 cm long, slender, stellate-pubescent and with underlying glandular puberulence; involucellar bracts 5, lanceolate, 5-7 x 1 mm, ciliate (hairs 0.5 mm); calyx 5 mm long, more densely pubescent than involucel; petals ca. 1 cm long, yellow. Fruits unknown.
Discussion:As the name indicates, Pavonia heterotricha is distinguished by its strikingly heteromorphic indument on stems and petioles.
