1985 Checklist of Vascular Plants of the Anza-Borrego Desert

1985 Checklist of Vascular Plants of the Anza-Borrego Desert

Duffie Clemons

Revised by Tom Chester, 2006

This page contains just the checklist itself; first see the introductory material to it.
The Checklist

The list below gives all the taxa from the original Clemons Checklist that have vouchers or at least an indication that a voucher is present. The voucher status is given separately for each Floristic Area. A bold number indicates a voucher is present, either as reported by Clemons from the SDNHM Herbarium, or as found from the procedure for checking for a voucher given above. Non-boldface numbers or the letter B indicate the taxon is only reported to occur in that Floristic Area, with a B indicating a report in Beauchamp.
An asterisk before the common name indicates a taxon not-native to California.
There is also a version for compact printing which does not have the regional information (27 pages). By comparison, the printed version of this webpage is 41 pages long.
