Notes Glossary
  • Move to List 1B? Some plants from AMA, ELD, SIS, and TRI cos. resemble S. celata, but are outside of known range; needs further study. Herbarium material is difficult to identify; needs field surveys. Similar to S. asprella, S. gigantea, and S. robusta. A synonym of S. malviflora ssp. asprella in TJM (1993). See Flora of California 2(1):492-493 (1936) by W.L. Jepson for original description and MadroƱo 56(2):285-292 (2009) 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.
Includes unprocessed quads for CRPR 3 and 4 plants; unprocessed location data has not been quality controlled and may contain errors.
