The Flora of the PCT: C2 Cottonwood Trailhead to Whitewater Canyon: Area Flora

The Flora of the PCT: C2 Cottonwood Trailhead to Whitewater Canyon: Area Flora

See The Flora of the PCT: C2 Cottonwood Trailhead to Whitewater Canyon 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 #Pls gives the minimum number of plants, up to a maximum of 99 plants, for species seen in the field survey on 8 January 2015. Species with RT in that column were seen only by RT and Shaun Hawke in a survey of the entire trail on 24 March 2013. No abundance estimates were made in those surveys. Species with V in that column were vouchered from the trail.
For species seen by us, an abbreviation is sometimes given just before the number of plants, to indicate uncertain determinations; 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 (4 pages) or pdf Clickbook booklet (1 double-sided page). (See printing instructions for an explanation of these options)
