Picea and other coniferous forests; 2900–3200 m. Gansu, Jilin, Nei Mongol, NW Sichuan, Xizang, NW Yunnan [Japan]. Flowers of the Chinese plants possess a longer spurlike process that extends beyond the apex of the lip blade and are generally paler in color than the widespread European and N Asian typical variety of this species. Further critical comparison with authentic material of Calypso bulbosa var. speciosa from Japan would be desirable. |
