圆叶菝葜 yuan ye ba qia

Vines climbing. Stem branched, terete, 1--2 m, woody; branches densely verruculose, sparsely prickly. Petiole 1.5--2 cm, scarcely winged; abscission zone distal; tendrils usually present near base. Leaf blade suborbicular, 4.5--7 × 4--6.5 cm, thickly leathery, main veins 5, raised on both sides except midvein concave adaxially, base rounded, apex mucronate.

Pinus forests; ca. 300 m. S Guangxi (Dongxing Xian) [Vietnam].

This species is closely related to Smilax lunglingensis which has similar inflorescences and flowers. Only sterile material of S. bauhinioides has so far been collected in China; it clearly matches material of the same species from Vietnam.
