The Flora of the PCT: A1 Mexican Border to Highway 94: Area Flora

The Flora of the PCT: A1 Mexican Border to Highway 94: Area Flora

See The Flora of the PCT: A1 Mexican Border to Highway 94 for an introduction to this checklist.
This version of the Checklist gives the plant species from the trail, as well as from vouchers from the surrounding area, in plant family order, with the Family and Scientific Name from the 2012 Second Edition Jepson Manual.
The column #V gives the number of vouchers for this area, with a maximum value of 9.
The column #Pls gives a rough estimate of the minimum number of plants that we saw in the 3 November 2014 survey, with a maximum value of 99 plants. The main intent of this column is to indicate the species for which we found very few plants. The column contains RT for species seen only in 4/27/13 survey, where no estimate of the abundance was made.
The entry is preceded by an indication of the uncertainty of the determination; see abbreviation for the determination uncertainties.
See Information about the links from the Scientific Name and Common Name.
Version for printing, without lines and other text on this page: html (8 pages) or pdf Clickbook booklet (2 double-sided pages). (See printing instructions for an explanation of these options)
