A very difficult genus, highly variable at many levels and needing much additional research.


H. cylindrica Hook. var. alpina S. Watson

2 other vars. from nw US & B.C., with leaf blades generally > 3 cm, generally strongly cordate, occur with var. a. in se OR and may be discovered in MP: var. cylindrica (petiole densely glandular and stiff-hairy) and var. glabella (Torr. & A. Gray) W.E. Wheelock (petiole glabrous to sparsely glandular).
