Mile: 0.00 includes all mileages from 0.000 to 0.009; etc.

S: Side of trail on which the first occurrence is found: left, right, both, or center

#: On-Trail species are numbered in order of first occurrence on trail (touchable without leaving the trail). Off-trail species are in parentheses.

id?: Species without an entry in this column are positively identified. "?" means we are just guessing the identification; "sp" means the genera is probably known, but the species name is uncertain; "~" means we have 95% confidence that this is the determination, but have not yet positively identified it; "ssp" means the subspecies or variety needs to be determined.

#here gives the minimum number of on-trail plants of this species on this trail, with the number of locations on this trail following the /, using maximum values of 99/9. 1/1 means a single plant in a single location; 10/9 means 10 plants occurring in at least 9 locations, etc.

#all gives the number of plant trail guides, from all over southern California, that contain this taxon.
