Flora of the Pine Belt of the San Gabriel Mountains: Latin Name Changes

Flora of the Pine Belt of the San Gabriel Mountains: Latin Name Changes

This page contains the list of name changes that I have made to the Flora of the Pine Belt of the San Gabriel Mountains by RT and Shaun Hawke. The name changes were made to conform to the Jepson Manual.
The right hand column of older Latin Names usually includes the name used in the original Hawke Flora. However, it will not mention if a variety or subspecies was dropped in the Jepson Manual.
