PREFACE. 



As a student of the flora of southern California, the 
author has long felt the need of some one book contain- 
ing descriptions of those plants known to occur in our 
region. While it is essential that one doing critical 
work should laboriously search through scattered liter- 
ature, the average student, and especially the novice, 
will find such a course impossible. In an endeavor to 
supply this need, the author has written this book. Not 
that he feels that the flora is so well known that such a 
work will prove adequate for years to come, but rather 
to bring together what knowledge now exists concerning 
the systematic side of our most interesting plant life. 
That many mistakes must unavoidably occur, and that 
many plants are yet to be added, is clearly apprehended. 

The exact area included in this volume is the coast 
slope of Los Angeles and Orange Counties. This terri- 
tory comprises a large portion of the great southern 
California valley, as well as the following mountain 
ranges, in each of which we name the culminating point : 
Sierra Santa Monica (Castro Peak 3946 ft.), Sierra San 
Fernando (San Fernando Peak 3793 ft.), Sierra San 
Gabriel (Mt. Gleason 6493 ft., San Gabriel Peak 6172 ft., 
Mt. San Antonio 10080 ft.), Sierra Santa Ana (Santiago 
Peak 5675 ft.). Not a few of the more conspicuous and 
common plants of southern California not known to 
occur within our boundaries are included, however, so 
that the student will find that a great majority of the 

866 



iv Preface 

plants to be met with on the coast slope south of Point 
Conception are described. 

In the preparation of the text the author has made 
frequent use of published descriptions, especially original 
ones, only such changes being made as seemed necessary 
either on account of uniformity or to bring out unob- 
served characters. Published lists of our local flora 
have also been constantly consulted, but it is only jus- 
tice to the author to say that he has personally collected 
nearly all the plants included in this work and has 
added many species not heretofore reported from our 
region. Duplicates of these specimens, as well as many 
others from southern California, are to be found in the 
Leland Stanford Jr. University Herbarium. 

The author wishes to express his thanks to the follow- 
ing persons for assistance in various ways : Mr. S. B. 
Parish, Dr. A. Davidson and Dr. H. E. Hasse for valuable 
notes; Miss Alice Eastwood for the privilege of examin- 
ing the material in the California Academy of Sciences 
Herbarium ; Dr. N. L. Britton, Dr. B. L. Robinson, Dr. 
E. L. Greene, Dr. P. A. Pvydberg and Dr. J. K. Small for 
notes on doubtful forms ; finally to Prof. William R. 
Dudley, who has not only given many critical notes and 
valuable suggestions which have aided greatly toward 
the completion of the work, but has also shown many 
personal favors which have rendered the task a pleasant 
one to the author.

Family 6. GRAMINEAE. GRASS FAMILY. 

Annual or perennial herbs of various habit, rarely 
shrubs or trees. Stems (culms) generally hollow or 
sometimes solid, the nodes closed. Leaves sheathing, 
the sheaths usually split to the base on the side opposite

borne at the base of the leaf-blade. Inflorescence spicate, 
racemose or paniculate, consisting of spikelets composed 
of 2-many 2-ranked imbricated bracts (glumes), 
the 2 lowest in the complete spikelet always empty, 
1 or both sometimes wanting. One or more of the 
upper glumes usually contains in the axil a flower, which 
is usually inclosed by a bract-like awnless organ called 
the palea, placed opposite the glume with its back to the 
axis (rachilla) of the spikelet, generally 2-keeled.

dioecious, subtended by 1-3, usually 2 minute hyaline 
scales (lodicules) placed at the base of the ovary oppo- 
site the palea. Stamens 1-6, usually 3 ; anthers 2-celled 
versatile longitudinally dehiscent. Ovary 1-celled, 1-

pound or rarely entire leaves and irregular or regular 
flowers. Leaflets mostly entire, the upper somtimes 
converted into tendrils. Calyx 4-5-lobed or 4-5-cleft,

stamens or more commonly 5 and irregular ; the stand- 
ard superior larger and external, covering in the bud 
the 2 lateral ones (wings), these covering the 2 infer- 
ior pair which are more or less united above, forming 
the keel. Stamens and pistils enclosed in the keel. Fila- 
ments 10, 9 commonly united below into a sheath about 
the pistil and 1 distinct (diadelphous) , or all united 
(monadelphous) , or distinct ; anthers 2-celled, dehiscent 
longitudinally. Pistil simple, free, becoming a legume
