川鄂美穗草 chuan e mei sui cao

Calorhabdos sutchuenensis Franchet, Bull. Soc. Bot. France 47: 18. 1900.

Stems usually winged. Filaments mostly glabrous. Fl. Jul.

* E Sichuan (Chengkou Xian, Wuxi Xian), W Hubei (Fangxian, Shennongjia Linqu).

The type locality of Calorhabdos sutchuenensis is Chengkou, E Sichuan, from where the specimens examined seem to be rather different from typical Veronicastrum brunonianum in having stems winged and filaments glabrous. However, the examination of two specimens from the Shennongjia Mountains of W Hubei showed that one had winged stems and hairy filaments, while the other had wingless stems and glabrous filaments.
