It is now more than forty years since the publication of Mr.
Ohiey's Catalogue of Khode Island Plants,* which was the first
enumeration, other than the partial lists occasionally made by
visiting botanists, ever made of our plants. Since that time, and
more especially during the last decade, the study of Botany has
received increased attention, and is regularly taught in the
schools, generally, however, in a merely perfunctory and necessa-
rily superficial manner, but any attention given to the study is
an advance upon the previous total neglect of the science. The
Franklin Society has continued its discussions and lectures upon
botanical subjects, and an interest has been maintained and fos-
tered, which, it is pleasant to note, is more general at the present
than at any previous time; withal, Mr. Olney's genei'ous bequest
to Brown University, and the endowment of a jjrofessorship of
Botany under his will, has made the possibility of gaining a
knowledge of botanical science so comparatively easy, that it is
but reasonable to expect that this branch of Biology is to receive,
at least in part, that attention which it deserves.

When the first enumeration was made, many problems remained
unsolved which are to-day of easy explanation; text books to
which recourse might be had for careful generalizations from

the Providence Franklin Society, Stephen T. Olney, George Hunt, George Thur-
her and Henry B. Metcalf; the supplementary additions were made by Mr.
Olney.

accumulated observation, were in more than one direction at that
time entirely lacking; sources now broadly open to all were then,
so far as they at all existed, accessible to none other than the pro-
fessional botanist; new fields prolific in unimagined forms were
all around us, but for long time we were entirely dependent upon
our older brothers beyond the sea (with whom correspondence was
frequently in a foreign tongue), for information and knowledge,
which is now the privilege of the beginner.

It is not then strange that the first enumeration of Rhode Island
plants contained but one-third as many as we note in the following
list, which itself contains, it is believed, but little more than the
half of those species which grow without cultivation within our
borders.

This Catalogue is prepared at the suggestion of and under the
auspices of the Providence Franklin Society, and forms a portion
of its published proceedings. It has in large measure been com-
piled for a number of years, but for many reasons its issue has
postponed; yet we trust that the larger field which it conse-
quently covers will make amends for the delay, especially as we
are thereby enabled to add several hundred species.

The list could have been never made, certainly not to embrace
so much of the field which it aims to cover, without kindly and
very generous aid of many friends, all of whom will understand,
we trust, that whether their names appear in its pages or not, the
sense of obligation is here fully acknowledged and thankfully
remembered.

It would be impossible to mention all those who have in various
ways, by advice or suggestion or information, contributed to any
measure of success attained, yet it were unworthy not to acknowl-
edge an indebtedness, for many years in common with every bot-
anist, to him who for so long time was "/aciie princeps'''' of botanists,
and kindliest of men; on whom we were in so many ways depend-

Vll

ent, who was so entirely our wise leader and teacher, that we ever
refused to think of that time when he might be called away from
us. The imiiortauce biological studies now hold in American
schools and colleges and in an enlightened public esteem, and the
value therefrom which results to every commonwealth, is due
more than to any other to Dr. Asa Gray.

"All hearts grew warmer in the presence
Of him who, seeking not his own,
Gave freely,— for the love of giving,
Nor reaped for self the harvest sown."

May the memory of his simple, unaffected life, full of wisdom
and the desire to be helpful, linger long with us and strengthen
us, according to our degree, to similar loving acts of help !

We have to thank for assistance in special departments Mr.
William Boott, for kind aid in the nomenclature of the genus
Carex ; Dr. George Thurber and Dr. George Vasey for similar aid
in Gramineoi ; Mr. Willey, of New Bedford, for revision of the
Lichenes ; Dr. W. G. Farlow, of Cambridge, and Prof. D. C. Eaton,
of New Haven, for many additions to the list of Marine Algoe ;
Mr. C. H. Peck, of Albany, N. Y., and Mr. J. B. Ellis, of Newfield,
N. J., for revision of the Fungi; Mr. L. Lesqereux, for the nam-
ing and verification of many species of Musci ; Rev. Francis Wolle,
for information regarding FreaJi Water Algce ; Mr. Lathrop, for
contribution of Desmidiaceoe, &c. ; and other friends whose con-
tributions are noted in the text. Thanks are due to the Botanical
Committee of the Franklin Society, for their patience and consid-
eration in the extremely vexatious delays which have occurred,
and especially for the liberal manner in which they have provided
for the publication of these pages.

Gray's Manual — 5th edition, 1867 — has been followed in the
arrangement and nomenclature of the Flowering Plants and Ferns,

and in those cases wliere by proper authority such names have
been reformed, the former name is inserted in italics.

Dr. Vasey's various publications liave determined the arrange-
ment, &c., of Gruminea ;" Lesquereux' and James' that of the
Mnsci ;2 the late Prof. Tuc^kerman the Lichenes ;' Mr. M. C.
(!ooke's arrangement of the Finigi* lias been followed, with revis-
ions by Mr. Peck and Mr. Ellis; T)r. Farlovv has been the guide for
the Marine Algce/' and Rev. Mr. Wolle for the Fresh Water AlgcR.^
It should be noted that for convenience' sake the Marine and
Fresh Water Algie are separated, and in the one is followed Dr.
Farlow's ascending, and in tlie other Mr. Wolle's descending
series. Although unscientific, it was believed that there were suf-
ficient advantages in not merging all the Algety under one syste-
matic arrangement. The arrangement of the Diatomacece^ is that
in Pritchard. We follow Prof. Underwood's arrangement of
Hepaticoi.'^

The Mimci were determined or previous determinations verified
by Mr. Les(iuereux. Some of them, however, and all the Hei)a-
ticie, passed through the hands of the late Mr. Coe F. Austin.

The late Prof. Tuckerman very kindly determined, or verified,
the Lichenes, and all herein named passed under his examination.
The Fungi were all named by the late Rev. Dr. M. A. Curtis, or by
him in connection with Dr. Berkely; the revision of the same by

Mr. Peck and Mr. Ellis has been referred to. Valuable assistance
was received from Mr. Olney's Algca RJiodiacct, to which reference
is duly made by No. in the text, and wherever the names have
been reformed, the species as named in Ahj. Ehod. follows the
now accepted name in italics. Very valuable information regard-
ing a large number of Diatoms was obtained from Mr. S. A.
Briggs' papers in The Lens.

A great amount of material in Besmids, Diatoms, &c., await
determination, and all our fresh water pools, and ponds, and
brooks, teem with species yet to us unknown.

It has been the intention to insert the names of all plants so far
found indigenous to the State, and also all those not native, but
which have becom.e tlioroughly naturalized; the names of all
plants which did not appear to be perfectly established, are omit-
ted ; unquestionably there are some which deserve insertion, and
further study will allow their claim, but " consuetudo loci obser-
vando est," and it has been thought better to practice that con-
servatism which has heretofore characterized Rhode Island's
treatment of aliens, and make them fully earn citizenship before
allowing it. Naturalized plants are designated in the text by the
method of spacing commonly adopted.

Wherever the habitat is general it is not mentioned, but when
the plant has been found only locally, such fact is noted; when a
species has been noted by only one collector, such fact is stated,
save that in a few cases the note refers to the person by whom it
was first found ; the other notes will explain themselves. These
remarks do not apply to the Cryptogamia, as the marine algae
were worked out first by Mr. Olney, and the other orders mainly
by the writer.

Although this enumeration contains the names of upwards of
3,150 species and varieties, yet it is probably only the moiety of

those which grow in tlie State. The Phanerognins fiml Arrogens
are pretty nearly lull, the Anopfiytes less so, but no department of
the Thallogem, except the Mnrine Abjtz. is probably represented
in this list by one-half of those species which belong there ;
indeed, the enumeration was so evidently incomplete, that at first
it was intended to omit the entire class, except the Marine Algce,
and it is now inserted v/ith this explanation, and the hope that
micrcscopists may be induced to search out and add the missing
species to those herein name.d.

It may well be said in this connection, that questions of great-
est interest, not alone in a merely technical sense, await solution,
which may fairly be expected from the study of the life history
of the microscopic Algce and allies: that algoid and fungoid vege-
tation has much to do with disease in man and beast and higher
vegetable organisms, is held as proven; but whether as cause or
effect, or only coincident, is not entirely agreed. No greater ques-
tions of material value await determination, than the relations
between decay of physical life and the growth of microscopic veg-
etation. It may be perhaps tliat the study of these relations, by
some of our younger botanists shall lead to an elucidation of facts
and a determination of truths of unmeasured value to the com-
monwealth.

That family of plants, Protophijta, containing those species
always present in ferments, comprising Saccharoniycea, Bacillus,
Bacterium, &g., is not here noted ; a lack which some future
student must supply.

All that is claimed for this enumeration is its purpose to help
and encourage the beginner; — at the same time it gives, we
believe, correct information to the advanced botanist of facts
regarding liabitats and distribution of species. Claim to absolute
accuracy of determination, in every case, is not made, and it is
frankly admitted that corrections, as well as reformations, perhaps

XI

not a few, may be necessary. Information of necessary additions
or corrections is desired.

Criticism of the manner in which the work has been done may
be deserved; there can fairly be none, however, of the intent,
which is, to magnify the wonders of Nature, and prompt the
student, to look beyond Nahire\s merely outward appearing.

Whatever of value the following pages possess belongs in
largest measure to the help of kind friends ; whatever of incor-
rectness and imperfection to the writer.

To Hepaticoe, perhaps less attention has been given by American .
botanists, than to any order; it is certainly to be hoped that this
neglect may not be a continuing quantity.

No classification is yet quite satisfactory, and difficulties exist,
which can only be overcome by careful and long continued inves-
tigations. It would at first seem, that if Hepaticcn are related upon
the one hand to Muscl, and through Ricciaceoe upon the other
hand to Llchenes, that a reversal of the above arrangement were
called for, and that the thallophytlc forms should be at the end of
the series touching Lichenes, and cormophytic species should
immediately follow Musci ; but to quote Prof. Underwood:

"A lineal classification ***** does not properly present the
"natural position or inter-relations of the Hepaticoi and other
"groups, and indeed the affinities of the lower grouDs are too
" imperfectly understood to represent even a tolerable natural, that
•'is to say genetic relationship."

This remark will apply with force to the classification of all the
crytogamic orders.
