The Flora of the PCT
The San Ysidro Mountains B3, Warner Springs north

This version of the Checklist gives the plant species from the trail in plant family order, with the Family and Scientific Name are from the 2012 Second Edition Jepson Manual.

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

The columns #Pls give a rough estimate of the minimum number of plants seen in the 16 March 2014 and 23 November 2015 survey for section B3, with a maximum value of 99 plants. The main intent of these numbers is to indicate the species for which we found very few plants. The column contains x or RT for species seen in other surveys, where no estimate of the abundance was made. If we haven't seen a taxon, but it was vouchered from the PCT or immediately nearby, a V is in that column.

The vast majority of the vouchers in section B3 are from Charles Wolfinger, who may have the record for the number of vouchers on any section of the PCT, let alone on such a remote section! Charles has 188 vouchers from this section; and Nancy Nenow and collaborators have 37 vouchers from this section. Two other collectors have a single voucher each.

Some species are not solidly determined. A qualifier is given in the #Pls for those species to indicate how well-determined they are; 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.

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)
