PREFACE.

This bulletin is dedicated to the young people of Iowa. Every
boy and girl who has commenced the study of botany should have
& copy of it. The bulletin will not take the place of the regular
text-book on botany, but as soon as the student has become fa-
miliar enough with plants to analyze them, it will serve as a
check-list to those found growing in this state.

This preliminary list of more than three thousand species in-
cludes only the native plants and those that have been introduced
from other sections of this country, or other continents, and have
escaped from cultivation, and become naturalized and are now a
part of the flora of the state. When the list is completed it will
contain more than five thousand species. The cultivated plants
will receive attention in a later issue.

The limits of this bulletin would not permit extended notes
on species, or synonyms ; but the habitat of the plant ; the fre-
quency of its occurrence, and common name, when known, arc
given; but, unfortunately, many of the Thallophytes are known
only by the professional botanist and have no common names.

The study of plant life is world-wide, and botanists of dif-
ferent languages have accepted a common standard, which is
still in use. We hope the day is not far distant when the De-
partment of Agriculture at Washington will take up the matter
through its experiment station botanists, in cooperation witli the
colleges and universities of the country, and give the American
people an English translation of the accepted Latin classifica-
tion, then the study of plants in the common schools will be
as simple as any daily routine in school work. However, until
that time arrives, we must accept the situation as it is. and fa-
miliarize our tongues with these Latin names as best we can,
until a better system is evolved for the use of the millions who
will speak of plants only in their mother-tongue.

I have changed the order of arrangement of classes in the

ij-3,b 71

4 STATE HOETICULTUEAL SOCIETY

Thallophvtes from that followed by the systematic botanist, who
usually begins with the Alg* and then places the degraded forms
called Fungi, after the orders to which they are allied. I have
given more prominence to their functional differences than to
their structural arrangement, and have placed these parasitic
and saprophytic plants first, because they do not contain chloro-
phyll and are unable to convert dioxide of carbon into starch
under the action of sunlight, which substance enters so largely
into the composition of the cell structures in higher plants, but
must secure this organized matter for growth and development
from living or dead plants and animals. This order of arrange-
ment does not take into account any theory of evolution or degra-
dation, but is for the convenience of the student who studies
plants only from an economic standpoint, to have those of a sim-
ilar habit grouped near each other. We have placed the slime
moulds first, though they are not the least in size, but are cer-
tainly low in the scale of organized matter. Botanists have often
been in doubt whether they belong to the animal or vegetable
kingdom. Next in order are the bacteria ; among these are some
of the smallest vegetable organism, but with a good microscope we
can find them in almost every substance. They live in animals
and plants, often causing troublesome diseases, which sometimes
prove fatal to the animal or plant attacked. They are in the air
we breathe, the water we drink, and the food we eat; they live
in us, on us, and about us everywhere. The smuts, rusts and
mushrooms are larger and more easily seen. Many of these are,
however, quite destructive to our crops and are of special interest
to the farmer. "What are called Imperfect Fungi are not de-
fective in themselves, but are healthy, active organisms, as every
gardener knows, from the attacks they make on his plants. Leaf
spot on roses, beets and beans, scab on apples, rot in tomatoes,
and mildews, are common in the orchard and garden. Their life
histories have not been as thoroughly studied as some of the other
classes. After the Fungi come the Algae. Some of the smaller
species of this group can swim as gracefully as a fish. People
who have always considered a plant to be something with roots,
stem and leaves, that grows out of the ground, will be surprised
when they see the gyrations of some of these minute organisms.
We have placed the lichens at the end of the group for they

seem to be a happy blending of Alga? and Fungi into a mutual
copartnership, each working for the benefit of the other. •

I have followed Prof. T. IT. Macbride in the arrangement of
the Slime Moulds; Prof. F. D. Chester in Bacteria; Ellis and
Everhart in Pj^renomycetes ; and Britton's Mam ml in the
Pteridophytes and Spermaphytes. We obtained much of the
material for the bulletin from "Contributions to the Flora of
Iowa," by Dr. J. C. Arthur, published in 1876; "Bulletin of the
Agricultural College," by Dr. C. E. Bussey, 1884; "Proceedings
of the Iowa Academy of Sciences ; " " Proceedings of the Daven-
port Academy of Natural Sciences;" "Bulletins of the Labora-
tories of Natural History of the State University ; " " Reports of
the Iowa Geological Survey, ' ' and its ' ' Bulletin on Grasses, ' ' and
from the "Journal of Micology. "

I wish to express my gratitude to the botanists of the state
for their pains-taking and unselfish labor in publishing the
names of plants they have found growing in the state, and my
obligation to them for material used in compiling this bulletin:
To Prof. T. H. Macbride for the list of Slime Moulds and Mush-
rooms ; to Harriet Vandivert, Alice W. Hess and Nora Allen for
lists of Basidiomycetes ; to F. J. Seavers for list of Dis-
comycetes; to Prof. B. Shimek for Liverworts; to Prof. T. E.
Savage for Mosses; to Prof. B. Fink and R. E. Buchanan for
Algae ; to H. S. Hitchcock for Peronosporere ; to Dr. Henry Albert
and R. E. Buchanan for Bacteria; to Prof. Bruce Fink and Kate
Miller for Lichens, and to Prof. L. H. Pammel for list of Grasses
and Fungi. For County Floras that have been used, I wish to
express my thanks to C. R. Ball, E. M. Olsen, M. P. Somes, -M. B.
Peck, H. A. Mueller, R. J. Cratty, T. J. Fitzpatrick, M. J. Fitz-
patrick, W. D. Barnes, Fred Rupert, A. A. Miller, J. E. Gow,
J. P. Anderson, C. M. King, and many others whose work has
been examined and checked in preparing this bulletin.

Many changes have been made in classification of species in
recent years. I have not always taken kindly to sonir of these
changes. The names learned from Gray's and Wood's Manuals
more than thirty years ago still have a warm place in our
memory. We will probably continue to say Ampelopsis instead
of Parthenocissus, in speaking of the Virginia creeper, and

6 STATE HORTICULTURAL SOCIETY

Nymphcea sounds better to my ears than Castalia for our sweet-
scented White Water Lily.

There are many other changes like these in this list, that we
do not like to make, but believe it best to do so, rather than fol-
low my opinion, as it makes it easier for the student who is using
the manual of one author, to get the synonyms, than to follow
different authors on the same subject. We have also aban-
doned the use of capital letters for species. This I believe is a
move in the right direction, for it gives a better form than to use
capitals when the name of a person, country or substantive is
given to a species.

This bulletin has been written in the hope it might prove
helpful to the young people who are anxious to learn the names
of the plants, many of which they see daily while working on the
farm or strolling through the woodlands of the state.
