PREPAC E.,

In offering this Catalogue to the public, it is proper to state
that it has been prepared very hurriedly; the collection upon
which it is based, with the exception of the part taken from
the fine herbarium of the State Agricultural College, and from
a few comparatively small collections made in previous years,
having been made during the summer of 1875. Although
Botany is taught quite generally in the various schools of the
State, yet, with few exceptions, little or no attention is given
to the systematic preparation and preservation of native plants,
even in the higher Institutions; hence the difficulty of making
a complete showing of the Iowa flora.

In preparing the work, accuracy has been thought more de-
sirable than a larger list of names. It is to be hoped that
as soon as data can be secured, a more complete Catalogue,
with the Cryptogams added, may be published before many of
the rarer kinds of plants are exterminated by fires, cattle, cul-
tivation, and other causes.

The information is yet too’ meagre for a paper on the very
interesting subject of geographical distribution, Though lying
west of the Mississippi river, which would seem to indicate a
western flora, the State in this respect is characteristically
eastern. Vet the greater or less variation in the manner of
growth, development of parts, and habitat, often show the
effect upon the species of the western climatic and other
influences.

Collections have been received from various places in the
eastern half of the State, and the middle through to the Mis-

sour river, but the large tracts of country lying in the north-
west and southwest parts, with their rich and varied flora,
could not be reached.

T am’ under many obligations for valuable contributions and
assistance to PRor. C. E. Bessry, of the Iowa Agricultural
College, who published, in the ‘‘Fourth Biennial Report of
the Agricultural College, 1871,’? the first and only ‘* Contribu-
tion to the Flora of Towa’ thus far made, and who has
since been indefatigable in his labors in the Botanical field.
I am also greatly indebted to J W. Concpon, of East
Greenwich, R. I., and to Dr. Gro. ENGELMANN, of St. Louis,
Mo., for the examination and determination of many speci-
mens. Also to the following gentlemen of the State for con-
tributions of specimens and lists of plants of their respective
localities: J. G. Haupt, Davenport, list of plants from the
advance sheets of the ‘‘Report of the Academy of Sciences’’
of that place; E. W. Ho.way, Decorah: Dr. T. D. KEL-
LoGG, Doud’s Station, list of plants from Lee County; PROF.
Catvin, of the State University, Iowa City; Dr. Asa Horr,
Dubuque; Dr. Gro. M. KeL_Ltocc, Carthage, Ill, list of Lee
County plants; M. E. Jones, Grinnell; Rev. R. BurGeEss, late
of Woodbine; Dr. Wm. Younc, Greene; I. R. S. Biren,
Birmingham; also, to L. L. CapwerLi, conductor on the Mil-
waukee & St. Paul Railroad, Iowa Division, for assistance in
making collections.

Gray’s Manual, 5th edition, has furnished the basis of the
present work. Introduced plants are printed in zta/ics. Vari-
eties are numbered the same as species for facility of reference
and exchange. When plants have been reported but from one
locality and without specimens, the locality has been generally
placed at the foot of the page. The common names have
been} added for the use of those who prefer them. It has
been thought advisable to append descriptions of species and
revisions not included in Gray’s Manual,

APPENDIX,

17, RANUNCULUS AQUATILIS, L., var. STAGNATILIS, DC. (A. di-
vurtcatus, of Gray’s Manual.)

‘¢Frequent forms occur connecting this with the variety ¢richo-
piyllus. It can hardly be &. divaricatus, Schrank, as European
and Asiatic specimens of that species show a well-defined lamina to
the segments of the leaves, while in American specimens they are
always filiform.’ [Vatson’s Rep. in King’s Exp.

CLEOME, L.

Sepals distinct or somewhat united. Stamens 6 or rarely 4. Torus
minute. Pod linear or oblong, subsessile or stipitate.—Annual herbs
or shrubs with digitate or simple leaves and racemed or solitary
flowers. Benth. & Hook.

83. C. INTEGRIFOLIA, Torr. & Gr.—Annual, somewhat glaucous,
2%-3¥ high, widely branching; leaves 3-foliolate; leaflets lanceolate,
(the lower-most oblong) entire, submucronate; racemes sometimes
nearly 1° long; flowers large, showy, reddish purple, rarely white;
sepals united to the middle, persistent, segments triangular-acumi-
nate; petals with very short claws; stamens equal; pods oblong-
linear, compressed, much longer than the stipe. Alor. Col., Port. &
Coul.

gt. VIOLA CANADENSIS, L.—As yet found only at Decorah. Our
plant varies from the typical one in having much smaller pink flow-
ers, whose lateral petals are not bearded; as well as in general as-
pect, which is decidedly like 1” pudescens.

124. PORTULACA RETUSA, Engel.—Like P. oleracea, but greener,
and the stem more ascending, sometimes covering a space several
feet in diameter; leaves usually smaller than the common species;
sepals obtuse, broadly carinate winged; petals yellow; stigmas 3 or 4;
capsule 234’'-3’’ long, broader in proportion; seeds more strongly
tuberculate than in P. oleracea. Flor. Cal.

131. CALLIRRHOE INVOLUCRATA, Gray. —Hirsute;, stem branch-
ing, procumbent; leaves deeply 3-5-parted, covered with stellate
hairs, segments linear-lanceolate, laciniately 3~5-toothed; peduncles
erect, I-flowered, longer than the leaves; flowers few in a loose pan-
icle, about 1%’ in diameter, axillary, scarlet; bracteoles 3, linear-lan-
ceolate, 24 the length of the deeply-parted calyx; carpels numerous,
hairy, not wrinkled. Flor. Col., Port. & Coul.

3 THE FLORA OF JTOWA.

155. VITIS CORDIFOLIA, Michx.— Tall (or more rarely low) climb-
ing high, trunks not rarely 6’~9/ in diameter; leaves middle-sized or
small (21%4'— 3’ or 4’ in diameter), heart-shaped, mostly entire or very
slightly tri-lobed on the edges, with broad, shallow teeth, usually
smooth and shining, more on the upper than on the lower side, the
young ones sometimes, and very rarely the old ones, with short hair
on the ribs below; berries small, in large, mostly loose bunches,
black, without a bloom, maturing late in the fall, usually only with
a single short and thick seed, marked by a prominent raphe. —This
grows more especially in fertile soil, and is common in river and
creek bottoms. Lauge/m. tn 6th An, Rep. Lnsects Alo.

156. VITIS RIPARIA, Michx., (1% cordifolia, Michx., var. riparia,
Gray.)— Mostly a smaller plant than the last, but with larger (3'-5’
in diameter) and more or less incisely 3-lobed, glabrous, shining (or
rarely when young, slightly hairy) leaves, the lobes long and pointed,
the teeth also more pointed than in /* cordifolia, berries usually
larger than in the last, mostly with a bloom, in smaller and often
more compact bunches, commonly 1~2-seeded; seeds with a less

‘prominent raphe. —This species prefers thickets or rocky soil on river

banks, che northern form has fewer and larger berries in a bunch,
and is easily distinguished from J. cord?folia. The fruit ripens ear-
lier than the former and is pleasanter. Luged/m. tn Jnsects Wo.

189. DALEA LAXIFLORA, Pursh.—Glabrous, 3°--4° high, erect,
branched above; branches slender and spreading; leaflets 4-5 pairs,
linear-oblong, 2’’- 3’ long, 12’ wide, strongly dotted; spikes pani-
cled, few-flowered; flowers distant; bracts very broad, almost or-
bicular, glandular, coriaceous, glabrous, slightly cuspidate, embrac-
ing the flower; calyx deeply cleft, teeth long,setaceous, beautifully
plumose; corolla white, keel twice as long as the wings, vexillum
cordate, very small, sometimes with 4 approximated glands near the
middle. Flor, Col., Port. & Coul.

241, POTENTILLA RIVALIS, Nutt. ~ More slender than P. .Vorve-

(CIRSIUM, Tourn., of Gray’s Manual.) This change is the result
of a more exhaustive study of the genus and leaves the synonymy as
given in the body of the Catalogue. It does not otherwise effect the
