PREFATORY NOTE.

The "Synopsis of the Flora of Colorado," which the survey now pre-
sents to the public, has been prepared by Prof. Thomas C. Porter, of
Lafayette College, Easton, Pennsylvania, and Mr. John M. Coulter, one
of the assistants connected with the survey for the past two years. It
is intended to be a type of a series of "handbooks7' of different branches
of natural history, to be published from time to time as a part of the
series of " Miscellaneous Publications," for the use of students all over
the country. 2fo. 3 of the series is now passing through the press, and
has been prepared by the eminent ornithologist, Dr. E. Cones, U. S. A.
It will form an octavo volume of several hundred pages, bringing the
whole subject of western ornitholgy up to date. The mountain regions
of Colorado are now so accessible to the traveling public, that this
synopsis will prove a most valuable aid to students, and travelers who
can, are annually visiting Colorado in great numbers. Indeed, the moun-
tainous portions more nearly resemble the Alpine districts of Central
Europe, not only in the scenery, but also in the different forms of veg-
etation. The tide of travel is fast turning in this direction, and the
demand for works ot this kind will necessarily be very great. It should
be stated here, that the obligations of the survey to Professor Porter,
for his share in the work, are very much increased from the fact that he
occupied several months in its preparation without compensation from
the Government.

SURVEY OF THE TERRITORIES, January 14, 1874.

LETTER TO THE GEOLOGIST-IN-CHARGE,

LAFAYETTE COLLEGE,
Easton, P#., January 15, 1874.

SIR: In lieu of a simple list of the plants obtained in Colorado during
the explorations of last summer, I have the honor to present YOU here-
with a condensed Synopsis of the Flora of the Territory, prepared in con-
junction with Prof. John M. Coulter of the Survey.

The work is based chiefly on collections made, in 1861 and succeeding
years, by Dr. C. C. Parry, whose indefatigable labors have added so
much to our knowledge of the flora of the region; in 1862, by Messrs.
Hall and Harbour; in 1867, by Dr. W. A. Bell, of Manitou Springs; in
1868, by Dr. F. Y. Hayden; in 1869, by B. H. Smith, Esq., of Denver;
in 1871, by Dr. George Smith and W. M. Canby, Esq.; in 1871 and 1873,
by Messrs. Meehan and Hooper; in 1872, by J. H. Eedfield, Esq.; in
1872 and 1873, by T. S. Brandegee, Esq., of Canon City, Kev. E. L.
Greene, of Pueblo, and T. C. Porter; and in 1873, by J. M. Coulter.

The plan followed in the Synopsis is that of Mr. Watson in his excel-
lent Catalogue, volume Y of Clarence King's Eeport. Descriptions are
given of all the orders, genera, and species not contained in Gray's
Manual, Chapman's Flora, and other botanies of the States east of the
Mississippi River.

For the elaboration of the Musci and Hepaticoe we are greatly indebted
to Leo Lesquereux, Esq., of Columbus, Ohio; of the Lichens, to Henry
Willey, Esq., of Arnherst, Mass.; and of the Fungi, to Charles H. Peck,
Esq., of Albany, IT. Y.

Thanks are due also to Dr. Gray and S. Watson, Esq., of Cambridge,
Mass., and Dr. George Thurber, of STew York City, for kindly assistance
in the determination of difficult and doubtful species; and to J. H. Red-
field, esq., of Philadelphia, for valuable services rendered.

To Mr. Brandegee, for his large and fine collections from the southern
part of the Territory, and to the Rev. E. L. Greene, for lists and speci-
mens of rare species, we are under special obligations.

References to the authorities consulted and used are to be found at
the proper places in the body of the work.

I regret that circumstances have prevented the completion of an intro-
ductory article on the geographical distribution of the plants embraced
in this synopsis.

THOS. C. PORTER.

Dr. F. Y. HAYDEN, U. S. Geologist.

rather narrow oblong subequal lobes ; lobes subentire, obtuse; fruit on
a long peduncle; cup hemispherical, about 5" broad and 3" deep; acorn
smaller than that of Q. alba, usually 9" long and 5" in diameter, some-

diversity of views among botanists as to the true position of this oak.
Mr. Watson (Amer. Nat. 7, p. 372) regards it as one of the many varieties
of Q. undulata, Torr., but it seems so widely different in the shape and
section of its leaves and size of the fruit from the figure of that species
as given in Ann. X. Y. Lye. 2, pi. 4, that we prefer to retain the old
name for the present. — At the base of the foot-hills, covering the dry

the size of a pea, are agreeable to the taste, with a slight terebin-
th in ate flavor, and are much sought after by the Indians. It abounds in
Southern Colorado on the foot-hills and at lower elevations. Its north-

upper palet bicarinate, ciliate on the nerves and conformed to the lower
one. — The plant has something of the habit of Trieuxpis ( Uralepis)
avenacea, Kth., and has been mixed with it by collectors, but is readily
distinguished by its larger and many-flowered spikelets and its carinate,
acuminate, and mostly entire lower palet. — Texas, Linahcimer, 738;

BY LEO LESQUEREUX, ESQ.

The mosses here enumerated and described were collected in Colorado
Territory, by Elihu Hall in 1865, Major Downie in 1868, Prof. Thos.
C. Porter, and by the assistants of Dr. F. V. Hayden and myself
in 1872 and 1873. A few mentioned in Hayden's Beport of 1872, from
the mountains north of Colorado, and in Watson Catalogue, from Utah
and the Uiutas, all species likely to be found in Colorado Territory,
are added. Considering that none of the botanists who have gathered
these materials made in their researches a specialty of this class of
plants, which mostly grow in deep and dark ravines of difficult

access, and that, too, the eastern slopes of the Kocky Mountains are /
mostly bare of trees and deprived of atmospheric humidity, the essen-
lial food of the mosses, this catalogue is already remarkably rich and
interesting in many points.

slender, firm, fibrous, stuffed, equal, concolorous. Plant very variable,
1-6 inches high ; pileus .5-2 inches broad. — Twin-Lake Creek, August.

AG-ARICUS YELTJTIPES, Curt. Caespitose ; pileus fleshy, thin on the
margin, convex, smooth, very viscid, dull yellow with a brownish disk
or bright reddish-yellow ; lamella close, rounded behind, slightly at-
tached, yellowish ; stem equal or slightly tapering upward, hollow or
stuffed, generally velvety and brown, sometimes pale yellow and prim-
rose. Plant 1-2 inches high 5 pileus 5-1.5 broad. — Twin-Lake Creek,
August.

AGARICUS ILLICITUS, Peck. Pileus fleshy, firm, broadly convex or
expanded, smooth, hygrophanous, very dark brown when moist, paler
when dry ; lamell* close, broad, tapering outwardly, plane or ventricose,
rounded behind, with a very slight decurrent tooth, pale dingy brown ;
stem firm, equal, hollow, scabrous, distinctly striate at the top, paler
than the pileus. Plant 1.5-2 inches high ; pileus 1-1.5 inches broad. —
Twin-Lake Creek, August.

* AGARICUS. 1 Twin-Lake Creek, August.

*LACTARIUS ? Twin-Lake Creek, August.

LENZITES SEPIARIA, Fr. Pileus coriaceous, tough, dimidiate, often
elongated, zoned, strigose-tomentose, brown, generally paler or yellow-
ish on the margin ; lamellae rather thick, slightly branched or anas-
tomosing, yellowish, inclining to brown.

Yar. ft. POROSA. — Lamellae abundantly anastomosing and forming
pores. — Mount of the Holy Cross and Twin-Lake Creek, August.

DACRYMYCES STILLATUS, STees. Subrotund, convex, often plicate,
yellow or orange, color persistent ; spores multiseptate. — White House
Mountain, August.

PUCCINIA PORTERI, Peck. (n. sp.) Spots none; sori aniphigeuous,
crowded or scattered, rotund, rather small, prominent, brown ; spores
oblong or obovate-oblong, constricted in the middle, about .0016 inch
long, .0007-.0009 inch broad ; peduncles hyaline, one-half to twice the
length of the spore. On leaves of Veronica alpina. Twin Lakes, July.
The sori, which are about .018 inch in diameter, occupy the whole under
surface of the leaf, being so closely placed as to appear almost confluent.
In some instances they appear suffused by a cinereous hue, due, perhaps,
to the germination of the spores. The sori on the upper surface of the
leaves are scattered and comparatively few. The species seems to be
related to P. brunnea, Billings, from which it may be separated by its
amphigenous habit and hyaline peduncles. Dedicated by its discoverer,
John M. Coulter, to Prof. T. 0. Porter.

PEZIZA VULCANALIS, Peck. Hay deli's 6th Arm. Rep., 1872. Cup fleshy,
funnel-form, stipitate, crenate on the margin, smooth when fresh, rugu-
lose and more or less brown when dry; hymeuium pale orange; stem
slender, solid, smooth, brown ; asci cylindrical ; paraphyses slightly thick-
ened at the tips ; spores elliptical, smooth, 0.0004-0.0006 inch long, 0.0003
inch broad. Plant, 6-10 lines high ; cup 4-6 lines broad. — Ground.
Twin-Lake Creek, August.

PEZIZA SCUTELLATA, L. Cups scattered or gregarious, sessile, shal-
low or plane, vermillion, externally paler and hispid, with straight brown
or black hairs; asci cylindrical; paraphyses clavate at the tips; spores
elliptical, .0008 inch long. Plant usually about one-fourth of an inch in
diameter, the hymenium fading in drying. — Twin-Lake Creek, August.
