Flora of Fuller Ridge Area, San Jacinto Mountains

Taxa Rejected From The Checklist


This is a very preliminary checklist for the Fuller Ridge Area of San Jacinto Mountain. The southern boundary is roughly the latitude of the Black Mountain Trail. The northern boundary is north of Fuller Ridge where the slope becomes too steep to explore, which occurs at roughly 6400 feet elevation. The western boundary is at the California Riding and Hiking Trail. The eastern boundary is Fuller Ridge itself.

We are currently working on the flora of this area. The main purpose of this page now is just to help us as we explore this area. Hence most of this page is just a skeleton to hold the preliminary checklist for us to use in the field.


Procedure For Compiling The Checklist

The Checklist was compiled by the first author from online vouchers and from field work done by both authors from three different areas.

The vouchers were obtained using the following searches of the Consortium of California Herbaria on 4 August 2011:

Duplicate vouchers were removed, and each voucher was examined to see if it was inside the target area. For example, nearly all of the Snow Creek vouchers were taken at much lower elevation; a simple sort on elevation identified most of those.

The species list from the vouchers was then culled to remove species names that probably do not exist in this area, either because the location was not precise enough to be sure that the voucher was taken from the targeted area, or because the species determination on the voucher was unlikely to be correct. The rejected vouchers are detailed below.

The above procedure resulted in a list of 60 taxa from vouchers.

Fieldwork has been done in three separate areas: the Fuller Ridge Trail, the small drainage from the Fuller Ridge Trailhead south to the Black Mountain Road, and a portion of the California Riding and Hiking Trail. The fieldwork in all of these areas is very incomplete. The Fuller Ridge Trail has only been botanized twice, and never in its entirety. The other two areas have been botanized only cursorily.

Despite the limited field work so far, 107 taxa have been found, including 78 taxa not found in the voucher list.

The total checklist below contains 138 taxa.

Important Caveats

Please note the following important caveats about this preliminary Checklist:

Checklist for Fuller Ridge Area

The Checklist is sorted first by category - ferns, dicots, and monocots - and then by family and scientific name. The Family and Scientific Name are from the 1993 first edition Jepson Manual. An asterisk before the Common Name indicates a non-native taxon. (Note that it is debated whether Poa pratensis is native or non-native to the mountains of southern California.)

To save space, a three letter abbreviation is used for the Family. See Plant Family Abbreviations to decode the abbreviation.

The columns that follow the names for each taxa contain the minimum numbers of plants seen in each surveyed area (FRT = Fuller Ridge Trail; FRV = Fuller Ridge Valley, the small drainage south of the Fuller Ridge Trailhead; CARH = California Riding and Hiking Trail), and the number of vouchers (V) for this area. The number of plants for Fuller Ridge Valley was estimated only one day later, which was also after surveying the California Riding and Hiking Trail, and hence those estimates are especially poor. The abundance of some species is just given as a single plant, since we couldn't remember for sure how many we saw.

See also the list of rejected species given below.

This is a working list, about which we make no guarantees at all until we officially release it. Use at your own risk!

Notes on Some Taxa

Taxa Rejected From The Checklist

Gnaphalium canescens ssp. beneolens, UCR18844. Subspecies beneolens is a chaparral species, found at lower elevation than this area. Subspecies thermale is the pine belt species. These two taxa are very similar, so it is possible that the voucher is misdetermined. More likely, though, is that this voucher is from outside the target area here. The locality for this voucher is just Black Mountain, and it might have been taken along SR243 west of this area at much lower elevation, which fits the dry roadside given in the voucher label.

Juncus macrophyllus, UCR24963 and UC2571. The vouchers are almost surely J. longistylis. These two species are very similar, and experts have annotated some San Jacinto Mountain vouchers differently at different times. The current concept of these two species assigns all the San Jacinto Mountain plants to J. longistylis (the second edition Jepson Manual specifically states exc SnJt for J. macrophyllus).

Chenopodium desiccatum, RSA597521; Lupinus andersonii, RSA595733; Phacelia hastata ssp. hastata, UCR98837; and Phacelia imbricata, RSA595740. All of these vouchers were taken by L. C. Wheeler, and these are all almost surely misdeterminations of the common San Jacinto Mountains species in this area: Chenopodium atrovirens, Lupinus hyacinthinus and Phacelia mutabilis. In fact, the two Phacelia vouchers that have different determinations are duplicates!

Voucher data provided by the participants of the Consortium of California Herbaria (ucjeps.berkeley.edu/consortium/) on 4 August 2011.

We thank Pam Pallette, Norm Johnson, Peter Bryant and Portia Arutunian for help with the 8/2/11 fieldwork.
