Sageretia hamosa (Wall.) Brongn.


Description from Flora of China

Shrubs evergreen, scandent, armed. Branchlets grayish brown or dark brown, with incurved, hooklike stout spines, glabrous or puberulent at base only, sometimes yellow-brown pubescent. Leaves alternate or subopposite; petiole 8-15(-17) mm, glabrous, sometimes yellow-brown pubescent; leaf blade adaxially shiny, oblong or narrowly elliptic, rarely ovate-elliptic, 9-15(-20) × 4-6(-7) cm, leathery, abaxially barbate at vein axils or sparsely pubescent, glabrescent, adaxially glabrous, lateral veins 7-10 pairs, prominent abaxially, impressed adaxially, base rounded or subrounded, margin serrulate, apex caudate-acuminate, acuminate, or shortly acuminate. Flowers sessile, glabrous, usually 2- or 3-fascicled in lax terminal or axillary spicate panicles; rachis ca. 15 cm, brown or canescent tomentose or densely puberulent; bracts ovate, small, sparsely puberulent. Ovary 2-loculed, with 1 ovule per locule; style short; stigma capitate. Drupe subsessile, deep red or purple-black at maturity, subglobose, 7-10 × 5-7 mm, with 2 pyrenes, often white powdery. Seeds brown, flat, ca. 6 mm, emarginate at both ends, asymmetrical. Fl. Jul-Aug, fr. Aug-Oct.

Because this species is quite similar to Sageretia lucida, previous authors have misidentified it as the latter; however, the latter differs in having smaller leaves, with lateral veins 5 or 6 pairs, adaxially not impressed, and rachis glabrous.

Forests or thickets on slopes, dense forests along canals; below 1600 m. Fujian, Guangdong, Guangxi, Guizhou, Hubei, Hunan, Jiangxi, Sichuan, SE Xizang, S Yunnan, Zhejiang [India, Nepal, Philippines, Sri Lanka, Vietnam].
