Flora of Strawberry Creek Gorge below Idyllwild, San Jacinto Mountains

This area is known locally as The Grotto.

This plant checklist was done as the result of a single visit on 8 June 2011 by both authors, augmented by a few species found on an earlier trip by Dave. The determinations of many species have been taken from voucher determinations, which may or may not be correct. Further work needs to be done on those determinations, as well as other determinations for which there are no vouchers. I.e., this list undoubtedly contains some misdeterminations.

The column #Pls gives our estimate of the minimum number of plants for each species that we saw.

The column #V gives the number of vouchers for each species. Caveat: the voucher list has not been reconciled with our taxon list, and hence there may be vouchers for some of the taxa that have just the species name, or a different subspecies name. For example, there are six vouchers of Vulpia microstachys var. confusa, but we have just determined the plants we saw to the species.
