See list of 2 species in this genus

Stem color, a critical character for identification, is lost in drying. Therefore, it is very 
important to note on herbarium labels (less than 1% of collections in regional herbaria note stem color in life).

  • 1a. Stems pink to red in life; plants flowering during the latter half of August and during September; stigma usually densely retrorsely pubescent
  • 1b. Stems light brown to yellow in life; plants flowering during June, July, and the early half of August; stigma usually sparsely pubescent
