Notes Glossary
  • Historical occurrences need field surveys. Threatened by development, non-native plants, and grazing. Possibly threatened by dam maintenance, road construction and maintenance, and recreational activities. Similar plants from MNT and SLO counties may be S. glandulosus ssp. glandulosus; see this name in TJM 2; further study is underway to determine its relationship to the S. glandulosus complex. See Bulletin of the Torrey Botanical Club 13(1):142 (1886) for original description, and MadroƱo 14(7):217-227 (1958) 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.
