Flora of San Marcos Hills

Flora of San Marcos Hills

Wayne Armstrong, 1973, 2003

This plant list covers the southern end of the San Marcos Mountains. Specifically, it includes

the portion of the San Marcos Mountains within the City of San Marcos;
the valley of Agua Hedionda Creek;
areas east and west of Twin Oaks Valley Road from San Marcos to its end at Gopher Canyon Road; and
the vernal pool area in the city of San Marcos bounded by Mirada Drive, Pacific Street, Linda Vista and Las Posas roads.

The original plant list was compiled by Wayne Armstrong in 1973, beginning after the fire of Spring, 1970, with two later Addenda, giving a total of 270 taxa. The list was digitized and names updated in accord with The Jepson Manual by Tom Chester on 5 March 2003. From a field trip by both authors on 8 March 2003, 12 taxa were added to the list; subspecies were determined for 11 species; and the identification was confirmed for another species.
The column Source in the table below gives the origin of each taxon, coded as follows:

Value Meaning
1 Taxon unchanged from original list
2 Taxon name updated to the Jepson Manual system.
3 Subspecies or variety dropped in the Jepson Manual.
8 Conversion of taxon name to the Jepson Manual system ambiguous.
9 Taxon added or refined in 2003

The column id? gives the further work that needs to be done for some taxa. The codes there are as follows: sp indicates that although the genera has been identified, there is uncertainty about the identification for the species; ssp indicates that the subspecies remains to be identified. A ? denotes where the updated name for a taxon has become ambiguous since that taxon became two separate species. Each of the possible new taxa are given below, and so marked. A ~ indicates a likely, but not 100% positive, id.
An asterisk before the common name indicates a taxon not-native to California.
