1. Cissus adnata Roxb. 紅毛粉藤

Large ligneous climber. Young shoots clothed with a rust-colored pubescence. Leaves round-cordate, nearly smooth above, acuminate, 5-15 cm long, 4-13 cm wide; stipules orbicular-ovate, adnate, with gibbose center and scariose margins. Cymes opposite to leaves, on villous peduncles, as long as petioles. Flowers numerous, small, usually drooping. Berry succulent, smooth, black; seeds usually solitary or 2 in each berry, ovoid, the lower end beaked. East India, Indo-China; Malaysia to the Philippine Islands. Taiwan, found in the southern part and on Is. Lanyu. PINGTUNG: Lu & Ou 7884. TAITUNG: Is. Lanyu, Sasaki s. n. 1926.

This is a new addition to the flora of Taiwan proper but not for Lanyu, from where it was reported by Hatusima in 1970.

It has been frequently misidentified as Cissus repens Lam. But it can be readily distinguished from it by its rust-colored pubescence on young shoots and by its bristle-serrate leaves.
