Checklist of the Vascular Flora of the Pinyon Flat Area, Santa Rosa Mountains The column with header #V gives the number of vouchers in the Pinyon Flat area. Georeferenced vouchers at the Consortium of California Herbaria were searched on 27 November 2012 for the area spanned by 33.57 to 33.63° N. Latitude, and -116.51 to -116.43° E. Longitude. All 72 vouchered species from the Jepson and Hall trip in 1901, Palm Canyon and return to van Deventer's, were included in this checklist even if they were georeferenced outside that area, since Jepson and Hall did not assign collection numbers in the order the plants were collected, and hence it is impossible to say for sure which ones were in our target area above 3000 feet in Palm Canyon or not. Jepson wrote The specimens as a whole were collected along the canon from the upper palms to van Deventer Flat, that is from about 2500 to 4500 feet. Specimens so included that were not found in the geographic search are noted with JH in this column. Note that many of those species were undoubtedly collected just above the Palm Grove at 2500 feet elevation, and will not be found in the upper part of Palm Canyon.
The last two columns give the minimum number of plants from:
- a single survey of the uppermost Pinyon Trail (column header Pnyn) by Tom Chester and Dave Stith on 25 November 2012. That survey is quite incomplete since at that time of year many annuals and perennials were not present. That survey covered the first 3.2 miles of trail, and included a 0.9 mile survey up Onstott Creek to the next tributary canyon east, and up that tributary canyon back to the trail.
- a single survey of the uppermost Palm Canyon Trail (column header Palm) by Tom Chester, Keir Morse and Nancy Accola on 21 May 2016. That survey covered the 1.7 miles of trail to get into Palm Canyon, 0.2 miles of the Canyon downstream, and 0.3 miles upstream.
Those columns also indicate whether there is any uncertainty in the determination with a symbol before the number.
