?AUS. CO-V!?. ZQOL

JAN 2/: I'lnO ^

During the period in wl^ich the botanical department of the San
Diego Society of Natural History was under his charge (from 1934
until th^ outbreak of the lifar, and the termination of his work in the
Museumjto enter war production work) Mr. Frank F. Gander under-
took a ^«t«fflatic collection of the plants of San Diego County.
This work resulted in a more exhaustive study of the flora than had
at any previous time been undertaken.

Many others have assisted in the collection of local material.
Miss Susan G. Stokes and Dr. Edith A. Purer have made outstanding
contributions to the herbariimfi, and others, in lesser degree. Appre-
ciation of their work is hereby expressed.

Results of this intensive collection were partially recorded by
Mr. Gander, but there were many breaks and all records were incom-
plete. His general plan has been followed, with, however, many
changes which the factual records seemed to make necessary, or
where subsequent collections have altered the picture.

The list includes those plants indigenous to San Diego County
and those alien plants which have become naturalized, or which
have escaped from cultivation andhave become established. Near-
ly 1800 species and varieties, representing 600 genera and 121
families are included.

The numbers given represent specimens in the herbarium of the
San Diego Society of Natural History. When the limits of the range
are given, many collections within these limits have been made.
Otherwise only known localities are given.

A map accompanies this list, which serves not only to locate
the places named, but also indicates the life zones, thus helping
to complete the story. A Gazetteer of localities cited accompanies
the map, together with summary of the geographical limits of the
County.

In the m£un, the nomenclature follows the Manual of Southern
California Botany by Dr. P. A. Munz. Only slight deviations are
made in line with more recently published conclusions. Meiny of
these changes have been made at the suggestion of Dr. Munz who
has most kindly read the manuscript.

That this list is incomplete is recognized; many sections of
the County are yet to be explored. Also it would be impossible to
exhaust those covered unless collections were made throughout
the year, in all sections. Alien plants are spreading with alarming
rapidity, and in consequence, natives are being overcome. However
there have been added a number of species not heretofore recorded
as occurring in the County and many extensions of range are listed.
It seemed well worth while to present it at this time.

The herbarium of the San Diego Society of Natural History is
open at all times to use by students.

Our thanks are due to many who have lent their time and knowl-
edge to the determination and checking on the material within their
special fields. A list of these with family or genus treated is given
on the following page.
