Discussion
Variety ditrichoides is a highly reduced, flagellate form of var. icmadophilus but with a distinctive appearance. It is disjunct from montane China (Chen P. C. 1941) to a single locality in the flora area (Northwest Territories, Mackenzie District, Nahanni Range, 61º43’N, 123º20’W, D. Vitt, 1977, BUF). The olive coloration and general appearance is similar to D. leskeoides but the plant is somewhat smaller and the alar auricles are lacking.
