The Regional Floras
- List by Political Region (doesn't include any from List by Geographic Region)
- List by Geographic Region
Our ultimate goal is to provide Regional Floras for each of the broad regions of Southern California. Each of the Regional Floras in turn will link to floras of smaller areas within each Region.
Until we create the Regional Floras, this page will link to all available floras (with the exception of our Trail Guides, which are presented separately). Some of these sub-regional floras are lists we have put together to help us with our Trail Guides, and some of them are floras done by others. Many of them are from Bob Muns.
The tables below also provide information about floras that are not online. We just began to add those floras in late 2005, so it will be a while before the list is very complete for them.
The Floras by Bob Muns are also collected together on a single page, since his lists are the largest and most uniform set of floras for Southern California.
Introduction to the Regional Floras
Search The Regional Floras A detailed description of how to search the Regional Floras online at this site to find all occurrences of a given taxon is given in Search tchester.org.
The Regional Floras The main list below is organized by geographic region of Southern California. Some floras are organized by political regions, and are given separately.
List by Political Region This section only includes floras that combine at least two geographic regions, and therefore doesn't include any floras from the List by Geographic Region.
