Checklist of the Vascular Flora of the Cactus Spring Trail, Santa Rosa Mountains

Checklist of the Vascular Flora of the Cactus Spring Trail, Santa Rosa Mountains

This is a checklist of all the species found as of 28 May 2008 on the Cactus Spring Trail, from its beginning at the Sawmill Trail Parking Lot to the wash just beyond Cactus Spring. This checklist also includes four species that are vouchered from this trail, but which have not yet been seen on the trail in my fieldwork. The voucher data were provided by the participants of the the Consortium of California Herbaria.
See Plant Guide to Cactus Spring Trail for an introduction to this trail, and for the Plant Trail Guide with plants in geographic order found along the trail.
This checklist is in traditional family order. As with all my online lists, the names of the taxa and their families conform to the Jepson Manual 1996 as far as possible.
This checklist also includes a cross-reference to the species number in the plant trail guide. Species #1 is the first one encountered at the beginning of the trail; species #203 is the last one, found at the end of the guide just beyond Cactus Spring. Species with the number 999 are found off-trail, usually just a short distance from the trail. Species with no number in the cross-reference column have not been seen, but have been vouchered from this portion of this trail.
The checklist also gives the abundance of each species found on-trail, as the number of individual plants for each species (maximum value of 99) and the number of distinct locations along the trail (maximum value of 9). These numbers are usually only estimates, and serve primarily to indicate which species are rare on this trail.
An asterisk (*) before the common name indicates a non-native taxon.
