Flora of the Pine Belt of the San Gabriel Mountains: Extensions to Identifications

This page contains the list of refinements that I have made to the identifications in the Flora of the Pine Belt of the San Gabriel Mountains by RT and Shaun Hawke.

I extended some of their identifications one level deeper when it was unambiguous, or nearly so, to do so. The unambiguous cases were mostly assignments of a subspecies or a variety when that was the only subspecies or variety of that species in the San Gabriel Mountains. An example of a nearly unambiguous refinement is where the Salix sp. in the original list became S. lasiolepis. This was done since Jane Strong and I have found that S. lasiolepis is the most abundant species by far in the Pine Belt of the San Gabriel Mountains.

The taxa on the original list by the Hawkes can be derived simply by taking away the deepest level of the identification in the following table, or by adding a qualification (such as making it a tentative identification) to the deepest level. For example, Salix lasiolepis below is Salix sp. in their original list, Lomatium nevadense var. parishii is Lomatium nevadense in their original list, and Solidago californica is S. (californica) in their original list.

In cases where Jane and I found two subspecies found in the San Gabriel Mountains, I did not refine their identifications, and left that taxon identified only to the species level.
