Notes Glossary
  • Difficult to determine rarity as some populations rarely flower. Populations often have small numbers. Threatened by logging. Difficult to identify from herbarium material. See Lindleyana 5(4):205-211 (1990) for original description, and The Wild Orchids of California, p. 109-110 (1995) by R. Coleman for species account.
