Initial Editorial Comments in no way mentioned in Munz or Munz Supplement (despite Kartesz & Meacham citation), Munz Southern California Flora, The Jepson Manual [Ed. 1]; indicated for CA, OR, BC (possibly extirpated), and e NA in Kartesz & Meacham; two records in SMASCH, collected 1958, 1961, Stanislaus, Tuolumne cos.; according to Source c, status uncertain, collections not recent, yet conditions of cited occurrences evidently would qualify for inclusion in the flora according to criteria employed by Jepson Flora Project (27 Feb 2003)
