The original determination is shown in the popup window. Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location. Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues. READ ABOUT YELLOW FLAGS CCH collections by month Duplicates counted once; synonyms included. Species do not include records of infraspecific taxa, if there are more than 1 infraspecific taxon in CA. Blue line denotes eFlora flowering time.
