Notes Glossary
  • May be morphologically indistinguishable from D. pulcherrima and D. yina, but distinct based on geography, cytology, and DNA. Previously assigned to D. yina, which does not occur in CA; plants previously considered D. yina in CA are either D. pulcherrima or D. willamettensis. See Proceedings of the Biological Society of Washington 47(34): 187-188 (1934) for original description, and MadroƱo 57(1): 20-41 (2010) for taxonomic treatment.

  • Notes:
      Definitions of codes preceding a county and/or quad:
      * Presumed extirpated
      ? Uncertain about distribution or identity
      ?* Uncertain about distribution, but presumed extirpated if once present
      (?) Occurrence confirmed, but possibly extirpated
      Species may be present in other areas where conditions are favorable. This data should NOT be substituted for pre-project review or for on-site surveys.
