Urena procumbens L.


Description from Flora of China

Subshrubs to 80 cm tall. Branches procumbent; branchlets stellate puberulent. Stipules subulate, ca. 1.5 mm, caducous; petiole 4-15 mm, hairy; leaf blades on proximal part of stem palmately 3-5-lobed to 1/2 blade, lobes rhomboid or obovate, gourd-shaped, 1-7 × 1-4 cm, both surfaces shortly stellate hirsute or densely woolly tomentose, base rounded to nearly cordate, margin serrate, apex obtuse. Flowers solitary or nearly fascicled, axillary. Pedicel 2-3 mm. Epicalyx ca. 7 mm, connate for ca. 1/3 length, sparsely stellate hairy. Calyx shorter than or nearly as long as epicalyx, lobes ovate, acute, stellate. Petals pink or white, 1-1.5 cm. Staminal column glabrous, as long as petals. Fruit globose, ca. 6 mm in diam., spiny and hirsute with long hairs and hooked spines. Seeds glabrous. Fl. Jun-Sep.

The identity of Urena procumbens has been confused, with most authors including it within U. sinuata Linnaeus, and others, such as Guerke (Fl. Brasil. 12, 3: 457-596. 1892), suggesting that it might not belong to the Malvaceae. Hu (Fl. China, Malvaceae [Fam. 153], 178. 1955) typified this taxon as a close relative of the more widely distributed U. sinuata, distinguished by the relatively narrower leaf blades, not orbicular in outline, with uniform, not heterogeneous, hairs.
