ABSTRACT
Documentation is provided for 23 taxa not included in other published flori sti c accounts o f the
Santa Ana Mountains. A repre sentat ive voucher specimen and generali zed distribution information are
cited for each taxon.
Key words: California , flora, Peninsular Ranges, Santa Ana Mountain s.
INTRODUCTION
The Santa Ana Mountains are situated at the north-
western end of the Peninsular Ranges in southern Cal-
ifornia, straddling the borders of Orange, Riverside,
and San Diego counties , The flora of the range is
among the best documented of any region in southern
Cali fornia. Lathrop and Thorne (1978) reported 848
vascular taxa in their preliminary inventory of the
range. A revision of the flora for the Santa Rosa Pla-
teau region (Lathrop and Thorne 1985) added 42 taxa,
and a floristic inventory of the San Mateo Canyon Wil-
derness Area of the Cleveland National Forest docu-
mented the presence of another 88 taxa (Boyd et al.
I995b). Floristic knowledge of the range was further
augmented by the addition of 66 taxa not reported in
other published accounts of the range (Boyd et al.
1995a). Recent fieldwork in the range as well as in-
vestigations in the herbarium have brought to my at-
tention another 23 taxa previously unreported for the
Santa Ana Mountains region .
Each of the following taxonomic entries is based on
at least one herbarium specimen. Herbarium acronyms
are cited and follow Index Herbariorum, 8th ed.
(Holmgren et al. 1990) , An alphabetical arrangement
is followed for families within subdivisions, classes,
or subclasses, as well as genera within families and
species within genera. Nomenclature follows, for the
most part, Hickman (1993). Family nomenclature is
that of Thorne (1992) for the flowering plants and
Crabbe et al. (1975) for ferns. Non-native taxa are in-
dicated by an asterisk (*) preceding the taxon name.
