Notes



Widely scattered, but most occurrences small. Not seen recently in SCL or SMT counties. Threatened by logging and horticultural collecting. Monitoring needed for protected populations on USFS lands to assess reproduction, which may be inadequate. Threatened in ID, candidate for state listing in OR, and state-listed as Threatened in WA. See Proceedings of the American Academy of Arts and Sciences 17:380 (1882) for original description, Lindleyana 2(1):553-57 (1987) for distributional information, and Fremontia 17(2):17-19 (1989) and The Wild Orchids of California, p. 65-68 (1995) by R. Coleman for species accounts.
