Cymes axillary, 1-4-flowered, monochasial; peduncle very tenuous, 0.5-1.7 cm; pedicel 3-5 mm, slightly elongate when fructiferous. Flowers white, ca. 4 mm in diam.; sepals oblong; petals narrowly ovate. Disk small. Ovary subconical; stigma slightly 2-lobed. Capsule obconical, ca. 7 mm, light reddish, usually 2-valved.

This species is rare in occurrence. Hong Shao (Bull. Bot. Res., Harbin 20: 126. 2000) described Maytenus mengziensis from Yunnan. Its affinity to Gymnosporia esquirolii needs further study.
