Introduction

This checklist is a start at a flora of Palo Verde Canyon, resulting from a single trip along one mile of Palo Verde Wash.

A total of 32 taxa were observed in or near Palo Verde Wash in our survey on 27 December 2007. Five of those taxa were additions to the voucher list for this area.

Checklist for Palo Verde Canyon

The Checklist is sorted first by category - dicots, monocots, and ferns - and then by family and scientific name. The Family and Scientific Name are from the Jepson Manual. An asterisk before the Common Name indicates a non-native taxon.

The first column after the Common Name indicates whether a taxon was present in the Palo Verde Wash survey.

The column # Vouchers gives the number of vouchers found in this area, as detailed above.

The final column, Clemons 1985, indicates whether a taxon was present in Floristic Area #16, the extended Borrego Springs area, in Duffie Clemons' 1985 Checklist of Vascular Plants of the Anza-Borrego Desert.

The number of vouchers in the table below totals to 295, not the 284 actual number reported above, since we failed to remove 11 duplicate vouchers when we tallied those numbers.
