While most geographic placenames can be found on maps, many names of places in Ventura County related to the County's flora may be historic and no longer in use, or not "official"; therefore, those used in the Flora of Ventura County are listed here.   This page lists those names for places of Ventura County.

One source of coordinates for Ventura County places is California Maps website.   It provides latitude and longitude coordinates and the USGS topographic quadrangle map on which it occurs.   This site has lots of the placenames for the County; however, there are still more, all of which are (will be) listed below.

This page is still under construction, so check back later.

Teaser: Do you know where "Griffins" is?   I struggled with it for many years until finally I found out.

And, where is San Antonio Hill?   Olive Day Thacher, of the Thacher School family, collected several plants from "San Antonio Hill", but it is not on any maps.   It is somewhere in the Ojai Valley area, and I bet it is the hill that divides San Antonio Creek and the Ventura River, but if anyone knows for sure, please let me know.
