Introduction

The Flora

The column headers are:

• #V: Number of vouchers in the SRPER area, with a maximum number of 9
• #Trl: Number of plant trail guides in which each taxon was observed by Tom Chester and Kay Madore

Species with no entry in either of those two columns have been observed off-trail in the SRPER, or were indicated as possibly being in the SRPER area in the Lathrop and Thorne Flora.
