Notes: 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 Madroño 14(7):217-227 (1958) for taxonomic treatment. |
