长圆叶梾木(原变种) chang yuan ye lai mu (yuan bian zhong)

Ardisia discolor H. Léveillé; Cornus paniculata Buchanan-Hamilton ex D. Don; Swida muchuanensis (Z. Y. Zhu) J. Holub; S. oblonga (Wallich) Soják; Yinquania muchuanensis Z. Y. Zhu; Y. oblonga (Wallich) Z. Y. Zhu.

Leaf blade elliptic to oblong, abaxially papillate. Inflorescence, abaxial surface of leaves, and petioles pubescent with short grayish appressed trichomes.

Broad-leaved evergreen and mixed broad-leaved evergreen-deciduous forests, thickets along streams; 800–3700 m. Guizhou, Hu–bei, Sichuan, Xizang, Yunnan [Bhutan, India, Kashmir, Myanmar, Ne–pal, Pakistan, Sikkim, Sri Lanka, Thailand, Vietnam].

Yinquania muchuanesis is restricted to S Sichuan (Muchuan). It was recognized on the basis of its smaller size (2–4 m tall) and subglobose fruit; C. oblonga is typically a tree 2–16 m tall, with ellipsoid or subglobose fruit. Given that Y. muchuanesis falls within the size range of C. oblonga and subglobose fruit are also found in C. oblonga, Y. muchuanesis is tentatively treated here as a synonym of C. oblonga. Further evidence is needed to determine the status of this species.
