Comments On the 2006 Checklist of the Vascular Plants of San Diego County (fourth edition)

This page is very incomplete, and serves for now just to give a few comments on this Checklist which expand upon the review published in Crossosoma in late 2006. I hope to do a proper job on this page in Fall / Winter 2006.

This is a partial list of new native taxa added in the 2006 Checklist that are not found in any of my 93 Plant Trail Guides or in any of the 65 floras I've digitized. I.e., this is a list of species that were very significant and very surprising additions to the San Diego County Flora, since they are found almost nowhere else in southern California. (Note that I haven't digitized every flora for southern California, and many areas, such as Imperial County, don't have floras.) I also give the Jepson Manual distribution for those taxa.

Note that there are many more new native taxa added in the Checklist; these are just the most remarkable ones. This list is partial because I haven't completely digitized the 2006 Checklist yet (about 10% is yet to be done).

The taxa that represent subspecies or varieties found previously only outside southern California are especially interesting. They might simply be the occasional specimen of a subspecies commonly found in southern California that overlaps in characteristics with ones found only outside southern California. On the other hand, they might call into question the validity of the subspecies themselves.
