The skeleton of this book has for eleven years formed a supplement to the
" California Flora," which describes only the plants of the coast region between
Monterey and Ukiah. Since it is not practicable to fill out this skeleton in the
way originally intended, it has been put into the improved form here described.
The "Flora" of the old manual has been replaced by descriptions of all the
orders whose species on this coast have conspicuous flowers. This part of the
book also contains descriptions of near two hundred and fifty species which are
mostly new, and over fifty generic names which in Greene's "Botany of the San
Francisco Bay Region" displace names used in this book. These synonyms will
be very helpful to those who use the former manual with this or other floras.
A complete glossary of the botanical terms and specific names found in this book,
and a glossary of generic names in connection with the index will materially aid
students. An analytical key leads the student to a description of the order to
which the plant in hand belongs. At the close of that description he is referred
to the page of the second part where keys lead to the genus and species. Return-
ing to the first part, the' new matter there is consulted before making a final
decision. This seemingly awkward prominence of addenda is perhaps advanta-
geous to the student, who is thus led to realize the progress of botanical work.
Moreover there is encouragement in the thought that the discovery of so many
new plants in the ten years just ended proves that there are species yet unde-
scribed which sharp-eyed seekers may find.

Since the descriptions here given are for the most part abbreviations of the
originals, their shortcomings should be charged to the compiler of this book. In
some cases, particularly in difficult genera, new species have not been given.
Many of Prof. Greene's new species are placed under generic names which he
does not approve. Most of these, however, were described by him under the
discarded names, and it is proper that his name should follow that of the species


as author. In the other cases his name, according to present usage, should
appear in parenthesis. Since this is a matter of little importance to beginners
and one difficult to manage it has not been attended to.

Because of the unsettled condition of plant names the present time is unfavorable
for the preparation of a flora of any country. More than ever before systematic
botanists are investigating the history of names, and, like other historians, they do
not agree. There are therefore added to the ever present questions concerning the
limitations of genera and species, questions concerning the priority of names.
The former never will be settled, and authorities are not likely to agree upon the
latter for some years to come. Meanwhile we must learn several names for each of
a score or more of the plants we yearly greet in our country rambles. For example :
In the collections of plants made in the United States last year the shrub com-
monly known as Nine-Bark doubtless bears five different names. Those using
"Gray's Manual " or "Wood's Class Book'* have labeled it Spiraea opulifolia;
according to " Bergen's Botany" and "Behr's Flora" it is Neillia opulifolia; in
the " Key to West Coast Botany" it is Physocarpus opulifolia; in Greene's "Flora
Franciscana" it is Ne.dlia capitata, and in the same author's " Botany of the Bay
Kegion" it is called Opulaster capitatus. Five plants so common that they may
be found on one hillside will, by those who use the "Bay Region Botany," be
given each a separate generic name, yet most botanists call them all Gilias. A
common wild cherry is Prunus emarginata in "Behr'fc Flora," Cerasus emar-
ginata in " Bay Region Botany," and Cerasus California in "Flora Franciscana."
Some idea of the number of plants known by more than one name may be gained
from the fact that over two hundred of the thirteen hundred species described
in the " Bay Region Botany" appear under generic and sometimes specific names
different from those given them in the " Botany of the Geological Survey." But
it must be remembered that, even in its present chaotic condition, botanical
nomenclature is incomparably better than that of so-called common names.
Most of our noticeable native plants are each known by a dozen or more locai
names. V. R.

SAN JOSE, Feb. 8, 1898.



In a general way we designate the objects around us by single names. We speak
of a stone, a wolf, or a pine; but to distinguish the kinds we naturally use two names,
as lime stone, sand stone; grey wolf, prairie wolf; nut pine, yellow pine, etc. This is
one step in classification, and the only one commonly taken. This natural plan of
double names was adopted by the great naturalist, Linnseus, who gave names to most
European plants, as well as to many of this continent. He wisely gave the Latin form
to his names, since that language (being the base of most languages spoken in civilized
countries) is the natural source of cosmopolitan names those truly common to all
people. Botanical names, then, differ from so-called common names principally iu
form, and they have these decided advantages: they more exactly represent the rela-
tions between kinds of plants, and they are names that are common to people of all
languages. In short, they are the true common names.

It is not true that botanical names are harder than local names. The most com-
mon of our ornamental plants are well known by their scientific names. No one thinks
of calling the following botanical names hard: Geranium, Aster, Verbena, Petunia,
Portulaca, Crocus, Phlox, Fuchsia, Iris, Magnolia, Oxalis, Azalea, Dahlia, Lobelia,
Arnica, etc. Most people talk familiarly of Camellias, Callas, Begonias, Acacias, etc.;
while our beautiful California plants, Clarkia, Collinsia, Eschscholtzia, Nemophila, etc.,
are well known by their proper names at least, in other countries.

Generic names correspond to the second parts of the compound common names, as
oak, pine, rose, etc. Some of these are the old Greek or Latin names of the plant.
Most generic names are either derived from Greek or Latin words descriptive of some
peculiarity of the plant, or they are commemorative of some botanist, as Thysanocarpus,
from Greek words meaning fringe and pod; Kelloggia, in honor of Dr. A. Kellogg, a
veteran botanist of this coast. Sometimes genera are named in honor of those who are
not botanists, as Fremontia, Hollisteria, Stanfordia, etc.

It will be seen that in the examples given a generic name in honor of a man is
formed by adding "ia" to his name. Sometimes "a" only is added, asBolaudra.

Specific names correspond to the first part of common names, but are written
after the generic names. Thus Oregon Oxalis is labeled Oxalis Oregona. Most specific
names are descriptive, as Gilia tricolor, Tricolored Gilia. Frequently a species is n^med
for the discoverer, as Eriogonum Nortoni, Norton's Eriogonum; or in honor of some one,


cabbage, radish. But you can do nothing with double flowers. A sweet pea could be
made to tell its proper or generic name in this way:

The sepals and petals together more than six, and petals not all united, brings
us again to Division 1. This time "A. STAMENS MORE THAN TEN"
is wrong. We take "B. STAMENS TEN OB LESS." "Ovary or ovaries
superior," etc., is right, but * "pistils, more than one, not united" is wrong. We
therefore look under "* * Pistil only one, simple or compound." The line marked
"a" is wrong; so, also, is "6," but "c. Herbs: leaves alternate" describes our
plant. "Corolla regular (petals alike) or nearly so" is wrong, so we take the next
long line " corolla irregular," etc. Reading under that the five lines beginning with
the word "stamens, we have no doubt that the first one, leading to the order
Leguminosse, is the right one. Turning to that order and onward, as before, w e
find a key in which the following leading lines are correct: " 2. Stamens all united
or one above distinct: herbs (except some in 3 and 7). * * * * Leaves pinnate,
finding in a bristle, imperfect leaflet or a tendril Style flattened, usually twisted half
around, one side hairy, 13." Seven pages further on we find: "13. Lathyrus,
Linnaeus." Since this plant is not a native of our country, we do not look further than
to note that there are about a dozen kinds which are natives.

When you think you have correctly determined the name of a plant, turn back
to the description of the order, and read it carefully once more, so as to be doubly
sure. Then if there is any new matter under the order heading read that also. If, for
example, you have traced a very common plant to the genus Phacelia, Euphacelia,
and have concluded that it is the tenth species described on p. 150, turn back to the
order Hydrophyllaceae, on page 54. Under the same genus and section there, near
the bottom of page 55, you find statements which may change your first decision.
What you have taken for Phacelia tanacetifolia may be Phacelia distans or Phacelia

Your labels should be written on slips of paper three inches long, and half as
wide. Let the name occupy the upper half, and on the lower half write in small letters
where the specimen grew and when you collected it. The label should be fastened in
the lower right-hand corner of the sheet on which you mount the plant. Only the left
hand end should be pasted down. Paper 17 x 22, cut crosswise, and folded to the size
S| x 11, is a suitable size fora school herbarium. The plant should be mounted on the
third page of the folded half-sheet.

or order indicated is not elsewhere described in this book. Generic names are in italic.
