Flora of Pine Cove Area, San Jacinto Mountains

This flora is made from vouchers; two surveys of the Webster Trail above 5000 feet elevation; two surveys of 5S10 from The Hub to Pine Cove; and a number of surveys of 5S09 from Pine Cove to the saddle with the Stone Creek Drainage, including partial surveys of Logan Creek.

This flora is for the Pine Belt area near Pine Cove, which reaches its southernmost limit at approximately the latitude of Dead Man's Curve on SR243, which is the tight switchback just southwest of Dutch Flat.

Vouchers were searched on 25 October 2018 for georeferenced vouchers from 33.74 to 33.80° N. Latitude and -116.76 to -116.73° E. Longitude. The localities were examined, and vouchers that were not clearly in the Pine Cove area were tossed, including all vouchers with a locality of "above Pine Cove".

The following voucher determinations were rejected as being erroneous or having taxonomic confusion with another vouchered species:

Arabis pulchra
Ceanothus integerrimus
Ceanothus spinosus
Collinsia heterophylla
Ericameria parryi
Gilia brevicula
Glyceria striata
Lupinus andersonii

Surveys of the Webster Trail were done on 9 May 2014 by Tom Chester and Dave Stith, and on 23 September 2019 by Tom Chester and Don Rideout. Only species observed above an elevation of 5000 feet were included in this flora. See Flora of Webster Trail for a list that includes species seen below 5000 feet elevation.

A survey of 5S10, including the small portion of 5S09 to Logan Creek, beginning at The Hub was done on 10 May 2013 by Tom Chester, Dave Stith, Keir Morse, and Adrienne Ballwey. Another survey beginning at the top of 5S10 was done by Tom Chester on 17 June 2020. Initially, this flora included species found anywhere on 5S10, but those not seen in the Pine Belt on 17 June 2020 were subsequently excluded. The number of plants given for 5S10 may still include some plants seen below the Pine Belt. The survey on 17 June 2020 also included a portion of a few mountain bike trails to the west of 5S10.

A survey of 5S09 from its junction with 5S10 to the saddle with the Stone Creek Drainage was done on 26 October 2018 by Tom Chester, Nancy Accola, and Don Rideout. Dave Stith has made many trips along this route, as well as multiple observations in Logan Creek. Another survey was done by Tom Chester on 22 June 2020.

The checklist contains separate columns for each of the above areas.

In addition, the checklist contains three additional species observed by Dave Stith in various places in Pine Cove, as well as four additional species observed by Tom Chester, Nancy Accola, and Don Rideout in a brief survey of Dead Man's Curve. These species have no entry in any of the last four columns in the checklist.

Dave has also observed a single waif of foxglove, Digitalis purpurea, blooming in Logan Creek one year, which is not included in the checklist.

The following gives some basic information about this checklist.


An asterisk before the common name indicates a non-native species.

The column #Pls gives our estimate of the minimum number of plants for each species that we saw from the sum of all surveys. An x indicates a species that was observed, but for which no abundance estimate was made.
