2 Million Herbarium Specimen Records for California

Continued efforts to database California vascular plant records in herbaria have narrowed in on the 2-million mark.  As of 31 January 2014, the Consortium of California Herbaria offer up 1,909,005 records.  Major non CCH records are: Consortium of Pacific Northwest Herbaria 29,142 records, and MO-Tropicos 33,098 records.  

A total of 1971,246 specimen records.
