Rubus lambertianus

Rubus lambertianus Ser. (Rosaceae) is a semi-evergreen, scrambling or sprawling shrub native to central, southern and eastern China, Taiwan and northern Vietnam. It produces long, arching, sparsely prickly canes 1–3 m long that root at the tips. The leaves are alternate, simple or shallowly 3–5-lobed (occasionally palmately compound on young shoots), 5–11 cm long, ovate to ovate-cordate, with serrate margins, pubescent veins beneath, and stipules that are deeply pectinate or laciniate — a distinctive character of the species. Flowers are 8–12 mm across with five white obovate petals, borne in lax terminal and axillary panicles in late summer to autumn. The aggregate fruit is small, globose, 6–10 mm in diameter, red when ripe, with rather few drupelets. It grows in thickets, forest margins and along streams at low to mid elevations. In Chinese folk medicine the roots and leaves are used as astringent and haemostatic remedies, and the ripe fruit is consumed locally.
