Introduction

This checklist is a start at a true flora of the Mason Valley area.

The species on this checklist come from a search on 29 January 2012 of the Consortium of California Herbaria.

The Consortium records were searched for vouchers with coordinates between ° N. Latitude, and - E. Longitude.

Localities of those vouchers were examined and ones not definitely in the target area were eliminated. A total of vouchers were out of area.

Vouchers determined just to genus were also eliminated.

The final list contained vouchers of taxa. Seven unique sets of collector names were responsible for (%) of those vouchers:

# Vouchers	% Vouchers	Collector
	100%	All Collectors

Adding together all the vouchers associated with a given name, which double-counts some vouchers since Larry Hendrickson and Jon Rebman often collected together, produces the following list of top individual collectors, with a distinct break between these collectors and the next most frequent collector:

# Vouchers	% Vouchers	Collector

Checklist for Mason Valley Area

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 1993 First Edition.

The column titled #V gives the number of vouchers found for the Mason Valley Area.

The column titled #BD gives the number of survey areas and floras in the Borrego Desert to the east in which each taxon was found. This gives an indication of which taxa are found here but do not extend to the east of that desert transition area.

Voucher locations for any taxon can be obtained by searching the Consortium of California Herbaria for the taxon name.
