All right. It's good to dig wild Smilax glabra behind people's houses. Smilax glabra is a climbing shrub of Smilax in Liliaceae. The rhizome is thick, the branches are smooth and spineless. Leaf blade leathery, narrowly elliptic-lanceolate to narrowly ovate-lanceolate, apex acuminate, usually with tendrils below green, and a detachment point near the top. It is distributed in China, Gansu (south) and the provinces south of the Yangtze River valley, until China, Taiwan Province, Hainan Island and Yunnan.
