CA Rare Plant Rank 2 Starting July 2013, CNPS Inventory divides CA Rare Plant Rank 2 into 2A and 2B, similar to our treatment for Rank 1. Names previously classified 2 are now 2B. 2A refers to Rank 2 that are thought to have gone extinct in California. (CA Rare Plant Rank was formerly called "CNPS List".)
Inventory 8th edition Same data, but with GIS and other improvements. Not all 7th edition features have been added yet - you can continue to use them here. To simplify access to the new features, such as GIS, each record in the 7th edition now has a link to the corresponding record in the 8th Edition.
