The Flora of the PCT
San Gabriel Mountains D1, Interstate 15 to Lone Pine Canyon Road

See The Flora of the PCT San Gabriel Mountains D1, Interstate 15 to Lone Pine Canyon Road 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 D1 contains an x if the determination is pretty solid; a "~" if that is the best guess for the determination; a "sp" if the species was unknown (with the "sp" placed in the same row as a likely determination from vouchers); and "?" if this was just a guess for the determination.

The column #Pls gives the number of plants observed on 20 March 2014 in a very dry year, updated with numbers from Walt Fidler in April 2017.

See Information about the order in which the species are presented, and the links from the Scientific Name and Common Name.

Version for printing, without lines and other text on this page: html (9 pages) or pdf Clickbook booklet (2 double-sided pages). (See printing instructions for an explanation of these options)
