GEOGRAPHICAL SuRVEYS WEST OF THE
One Hunprepta Meripran,
Washington, D. C., May 10, 1878.

Generau: I have the honor to submit herewith Chapter IV, Catalogue
of Plants, being an extract from Volume VI of those authorized to be pub-
lished by acts of Congress approved June 23, 1874, and February 15, 1875.

The volume comprises a number of reports upon collections of the
years 1871 to 1876, inclusive, made by Dr. J. T. Rothrock, surgeon and
botanist to the Expeditions of 1873-45, and by eminent specialists.

The collections obtained during the several years, after their identifica-
tion and classification, have been forwarded, through the Smithsonian Insti-
tution, for final lodgment in the herbarium of the Agricultural Department.

The following gentlemen have been engaged as field assistants in this
branch, viz: Dr. W. J. Hoffman and Ferdinand Bischoff in 1871, Dr. H.
C. Yarrow and H. W. Henshaw in 1872, John Wolf in 1873, Dr. J. T.
Rothrock in 1873—4—5, with Messrs. J. M. Rutter in 1874 and C. Shoemaker
in 1875 as sub-assistants, and in 1874—-5-6 Dr. Oscar Loew.

Other members of the Expedition have also contributed to the large
aggregate of specimens. ;

By dint of much pains and labor a number of species new to botanical
science have been discovered, twenty-seven of which are here figured for
the first time, as well as ten species rare, but not hitherto unknown. The
total number of new species is fifty, and two distinct genera have been
added to the known Flora of this portion of the United States. New and
well-marked varieties of older species have been obtained, and among them

number hitherto scantily represented in the largest herbaria. In many
I

cases the wider geographical range of known forms has been developed, as,
for instance, the discovery, in Arizona, of Ophioglossum vulgatum; and also
a number of rare species, as of the striking leafless tree of Arizona, the
Canotia, and specimens of which are thus added to the Government and
other herbaria. From the Agave plants a number are described as of value
for cordage and textile fabrics. The economic relations of various forage-
plants, native and introduced, are noted. The value of Chia (Salvia Colum-
barie) as a remedy and dietetic, as well as the medicinal qualities of other
plants, is defined. The present and prospective relations of the forests to
the settlement of the country receive mention, and tables prepared by Dr.
Loew of soil analyses at important points are introduced.

Although investigations in Botany, governed in a measure by the
sparsely settled condition of the regions visited, are but incidental to the
systematic purpose of the Survey, which has for its main object the deter-
mination of data necessary for the construction of a detailed topographical
map, yet it is believed that the material here presented, as the result of
examination, by specialists, of large and complete collections, will have its
value as a substantial contribution to the knowledge of the Botany of
portions of the United States west of the 100th meridian and south of
the 40th parallel.

Attention is invited to the authors of various parts of this report, whose
names appear on the title-page, and to whom so much is due for the skill
with which they have prepared their several parts, and a merited tribute to
the value of their services is hereby tendered.

To Prof. Asa Gray, the veteran Botanist, to whom doubtful points
have been submitted, thanks are due.

The zeal and fidelity displayed by Dr J. T. Rothrock, not only in the
field, but in the preparation of his report, and in superintending the colla-
tion of other reports, are worthy of all commendation.

The excellent typographical work of the Government Printing Office
in the publication of the quarto reports of the Survey is worthy of men-
tion, while the artistic plate illustrations of this volume, furnished by Mr.
Julius Bien, of New York City, are creditable alike to his artistic taste and
the excellence of his establishment. The plates were drawn by the well-

; . Pe known botanical artist, Isaac Sprague, of Cambridge, Mass., and Mr. W.
| . FH. Seaman, of the Agricultural Department.
: It is with pleasure that this opportunity is taken of recognizing the
industry, perseverance, and skill shown by those whose combined labors
have made collections the results from which are embodied in the reports
herewith submitted. )

Very respectfully, yours,

University or PENNSYLVANIA,
Philadelphia, Pa., November 14, 1877.

Sir: I have the honor to transmit herewith a catalogue of the plants
collected by your Expedition from 1871 to 1875 inclusive.

The plan adopted has been to describe all the species obtained by the
Survey, unless they were described in Gray’s Manual, or in vol. V, Botany,
of King’s Reports, by Mr. Sereno Watson, or either are, or are about to
be, described in the Flora of California, now in preparation.

Throughout, I have received generous aid from Prof. Asa Gray and
Mr. Sereno Watson. The latter gentleman contributes the entire account
of the Leguminosae.

Dr. George Engelmann has elaborated for the report those orders and
genera with which his name has been so long and so favorably associated,
i. e., the Cactacee, Cuscuta, Gentianacee, Euphorbiaceae, Asclepiadacea,
Juncus, Agave, Yucca, Cupulifere, and Conifere.

Prof. Thomas C. Porter has named and catalogued fully, with valuable
notes and descriptions, the plants representing the Labiate, Borraginacee,
Scrophulariacee, Polemoniacee, and Polygonacee. Mr. M. A. Bebb furnishes
an account of the Willows, a genus to which he has given long and careful
study.

Mr. William Boott contributes the paper on Carex. Dr. George
Vasey has carefully elaborated the Gramineae, and his paper forms one of
the most valuable portions of the volume. The very full paper by Prof.
D. C. Eaton, of Yale College, on the Filices, is believed to be a most
important addition to our knowledge of the species of this order found in
our Southwest. Mr. Thomas P. James and Mr. Austin have respectively

named, and, when required, described, the Musci and Hepatice, and Prof.
VII

Edward Tuckerman has determined the Tichones For fe
portions of the text I am responsible. |
The collections on which this catalogue is eee up were fined
almost entirely by the various collectors attached from time to time to the o
Survey under your charge, Dr. Hoffman, Dr. Loew, Prof. John Wolf, —
and myself obtaining the greater part. They have been obtained |
from Utah, Nevada, Colorado, New Mexico, Arizona, and California. 7.
There is thus brought together a large number of species, with their —
descriptions, that have hitherto been so scattered through our botanical
literature as to be practically unavailable to a large portion of those who

are interested in the botany of the regions embraced by this report.
I have the honor to be, very respectfully, your obedient servant,
J. T. ROTHROCK.
To First Lieut. Geo. M. WHxeE zr,
Corps of Engineers, in charge of
United States Geographical Survey.

EXOGENS.
RANUNCULACE&.*

Ciematis Doueiasu, Hook.—Clear Creek, Colorado. (92.)

CLEMATIS LIGUSTICIFOLIA, Nutt—Nevada, Utah, Arizona, and (80)
from Colorado. The number 498 from’ Camp Bowie, Ariz., is var. Cali-
fornica, Watson (FI. Cal. I, p. 3), characterized by leaves being ‘“silky-
tomentose beneath and often small”.

Ciematis Drummonpu, T. & G.—Dicecious, ‘silky villous beneath,
sparingly hirsute on the upper surface” (in my specimens from Cienega,
Ariz., No 567, both surfaces are smoothish), leaflets ovate, deeply and
acutely 3-lobed, sepals 4, lanceolate-oblong, carpels quite villous, with long
and plumose styles, stem slender, grooved, and altogether much more grace-
ful than C. ligusticifolia.

Curmatis ALPINA, Mill., var. Ocuotensis, Gray.—Subalpine ridges
among timber, at 10,500 to 11,500 feet altitude. (91.)

THALICTRUM ALPINUM, L.—South Park, Colorado. At 10,000 feet.
Typical specimens large. (94.)

THauictrum Fenpieri, Engelm.—Nevada, Arizona, Utah, Colorado in
South Park at 10,000 feet altitude. (144 and 280.)

ANEMONE MULTIFIDA, DC.—South Park, Colorado, at 9,000 to 11,000
feet altitude. (105 and 108.)

ANEMONE PATENS, L., var. Nutratiiana, Gray.—Mountains of Colorado,
at 6,000 to 10,500 feet altitude. (107.)

tufted root; petioles 1-4 inches long, leaves 3-5 parted, each segment
lanceolate-cuneate and trifid; involucre sessile, its leaflets 3-5 cleft; car-
pels tailless, compressed, oval, and glabrous. Entire plant more or less
densely covered with gray hairs; flowers white. Found in America most
commonly from Canada north, but growing in Colorado on alpine summits,
where, according to Mr. J. M. Coulter, it has been found at an elevation of
13,500 feet. (102 a.)

ANEMONE CYLINDRICA, Gray.—Willow Springs, Ariz.; rare there and
probably by seme accident introduced. (247.)

Myosurus minimus, L—Colorado; altitude, 8,000 feet and upwards;
specimens much dwarfed. (169.)

Ranxuncutus aquatius, L., var. staGnatitis, DC.—Denver. Flowers
almost as large as R. Purshii, Richardson, var. trichophyllus, Chaix. ‘Twin
Lakes, Colo., at 9,500 feet altitude. (113 and 115.)

RanuncuLtus Fiammuta, L., var. rEpTans, Gray.—Colorado. (172
and 173.)

RanuNncuLus HyDROCHAROIDES, Gray. (PI. Thurb. p. 506.)—Glabrous
throughout, flowering branches erect, numerous stolons branching off in all
directions and rooting ; lower leaves heart-shaped, and entire, or nearly so;
petioles 2-3’ long, expanding and sheathing at the base; upper leaves
lanceolate: peduncles about as iong as the upper leaves, from opposite the
axils of which they arise; sepals round, petals 3”, tapering into a claw,
which has a conspicuous gland below a small sinus; stamens about 25 ;
carpels 15-20, forming a head 2-3’ in diameter. Willow Springs, Ariz.,
growing in water at a temperature of 50° Fahr. at an elevation of 7,202
feet. A most interesting species, which I believe has not hitherto been
taken so far north. (217.)

RanuncuLus CymBauariA, Pursh—In Colorado grows everywhere in
low moist ground, evincing, however, a marked choice for alkaline soils, but
still flourishing in the freshest of snow water; altitude, 5,000 to 10,000 feet.

From Saguache, in the San Luis Valley, we have a form with an erect,
stout scape, bearing three or four flowers, having thicker and larger leaves,
and manifesting little or no tendency to produce stolons.

At Santa Fé, N. Mex., I collected it (10) at what I presume is the

identical location from which Fendler obtained his plant, published by Dr.
Gray in Pl. Fendl. p. 4, as 2. tridentatus, WH. B. K., and this I take to be
the same form as that above alluded to from San Luis Valley. In addition
to the difference noted by Dr. Gray in Pl. Fendl., I find the beaks of the
achenia are in my specimens more tapering than in typical &. Cymbalaria.
Collected also in California, Eastern Arizona, and Utah. (Colorado. 101.)

Ranuncutus Anpersoni, Gray.—Belmont, Nev. (Platei, vol. v, King’s
Report.)

RaNnuNCULUS ADONEUS, Gray. (Enumeration of Plants, Parry, Hall, and
Harbour. )—“ Low, sparsely villous, becoming with age glabrous ; root fasci-
culately fibrous; branching from base, with one to three leaves above, either
erect, simple, and one-flowered, or fleshy, decumbent, and with two or
more flowers; leaves twice pedately parted, segments narrowly linear, peti-
oles at base with dilated scarious margins ; peduncle short; corolla golden-
yellow; conspicuous petals flabelliform, twice as long as the hairy, oval
sepals; scale at base adnate, small.”* Usually a strictly alpine plant. My
specimens, however, were obtained as low as 6,000 feet above the sea-level.

RANUNCULUS GLABERRIMUS, Hook. (Flor. Bor.-Am. tab. v.)—Leaves
rather lanceolate than ovate.

Ranuncuus aFrinis, R. Br., var. CARDIOPHYLLUS, Gray. . cardi-
ophyllus, Hook. (FI. Bor.-Am. tab. v.)\—Colorado, at an elevation of 8,000
to 9,000 feet. (121 and170.) Willow Springs, Ariz., at 7,202 feet altitude.
Also collected by Dr. Loew in Western New Mexico.

RANUNCULUS SCELERATUS, L.—Cauline leaves, with a manifest tendency
to division of the lobes; otherwise like an Eastern form. Colorado. (99,
BLO; 111, 116.)

Ranuncu.tus Pursuu, Richardson—Among my specimens are a large
number with petals trifid and the scales distinctly three-lobed. Twin
Lakes, Colo, at an elevation of 9,500 feet. (117.)

RANUNCULUS HYPERBOREUS, Rottb., var. naTans, C. A. Meyer—Stem
weak, diffusely branched, glabrous, rooting from the nodes, creeping ; leaves
petioled, palmately 3-5-cleft; 8-5’ wide, lobes ovate, obtuse, petioles
6-12"; peduncles naked, 6-12’, often reflexed; sepals yellow, ovate, or

imperfection in my own specimens.

58 BOTANY.

oblong, 1-2” ; carpels forming a compact, globose head, style very short or
wanting. ‘I'win Lakes, Colo.; altitude, 9,500 feet. (100.)

RANUNCULUS MACRANTHUS, Scheele-— Usually regarded as a mere
variety of Lt. repens, L.; but I am satisfied from Mr. Watson’s showing that
it is distinct, as the greater villosity, the fewer stolons, the distinctly peti-
olulate leaflets, the more strictly reflexed sepals, the large flowers, and the
long beaks to the carpels all indicate. Willow Springs, Ariz.; altitude,
7,202 feet.

RANUNCULUS RECURVATUS, Poir.—Style not conspicuously recurved,
but in degree of hairiness, compressed achenia, relative size of sepals and
petals, shape and dentition of scale, markedly corresponding with descrip-
tion given by T. & G. Colorado. (162.)

CaLTHA LEPTOSEPALA, DC.—A common and characteristic plant in our
Colorado collection; 8,000 to 12,000 feet above the sea. (109.)

Trouuius Laxus, Salisb., var. ALBIFLoRUS, Gray.—One of the most
conspicuous early bloomers in alpine swamps, where, when found, it is
quite abundant. Associated with the preceding plant. (102.)

AquiLeGia Canapensis, L.—Arizona, lava rocks south of Camp Apache.
Leaves smaller than our Eastern form. (268.) Western New Mexico, at
high altitude, depauperate specimens. Coll. Loew. (164 and 167.) Utah.

AQUILEGIA FORMOSA, Fisch.—‘‘ Distinguishable from the last by its
elongated sepals nearly or quite equalling the spurs, and by its stouter
habit, growing only on stream banks in the mountains and flowering from
July to September. Nevada and Utah; ranging from the Rocky Mount-
ains to Oregon and Sitka, but not found in California.”—W arson.

AQUILEGIA CHRULEA, James.—Introduced largely into cultivation, and
to my mind the finest plant of the Rocky Mountains. Western New Mex-
ica; altitude, 6,500 feet. Loew. Colorado; open woods; common; alti-
tude, 10,000 feet. (163.) ‘Near Provo City, Utah. A reduced form of
this species, with bright blue flowers, was collected at Kanab in Southern
Utah, by Mrs. E. P. Thompson, in 1872. It has also recently been found
in the Sierras near Mount Whitney” [Cal.].—Warson.

AQUILEGIA CHRYSANTHA, Gray (Proc. Am. Acad. 8, p. 621). <A. lep-
tocera, Nutt., var. flava, Gray.—Usually, though not always, taller than

CATALOGUE. 59

the preceding. Hard to distinguish from A. cerulea by any mere descrip-
tion, as they exhibit transitions at all points. ‘The following appear to me
to be the chief differences: flower, at least in Southern specimens, always
golden yellow; sepals and petals nearly the same length, 1’; inflorescence
paniculate, and continuing until terminated by cold weather. Common in
damp ground and ravines of the mountain streams in the White Mountains
and Mount Graham of Arizona. It is certainly no exaggeration to say
that I have, near the Willow Springs, seen ten acres so completely covered
with this plant in full bloom, that everything else was lost sight of. Ari-
zona, at 7,000 to 10,200 feet altitude. (196.)

DELPHINIUM scopuULORUM, Gray (Pl. Wright. 2, p. 9)—24° high, pu-
berulent throughout; lower leaves with petiole 4-6’, becoming shorter
above; leaves round in outline, 8—5-parted, each division narrowly cune-
ate, again variously cut-lobed and toothed ; raceme slender, one foot long;
pedicels hairy, twice as long as the bract at base, one or two bractlets
usually immediately below flower; spur over half an inch long, thickish,
hairy, slightly curved, with markedly thickened extremity and one-half
longer than the puberulent sepals; lower petals nearly as long as the
sepals, slightly hairy within, upper one with a somewhat shorter blade, its
spur nearly as long as that of the sepal; carpels 3, smoothish. Flowers
are scattered loosely along the stem at intervals (when developed) of
an inch. A species as variable as it is elegant. Tanks south of Camp
Apache, Ariz. (263.) -Altitude, 5,625 feet.

Dexrumium Menziesu, DC.—Nevada; Snake River, Colorado. Dr.
Vasey informs me that the plant (No. 96) which I published in the list of
Colorado plants in 1874 as D. elatum, L, var., he has found, on comparison
with the specimens in the Department of Agriculture Herbarium, to be D.
Menziesi.

DeELPHINIUM ELATUM, L., var. ? occipENTALIS, Watson.—Plant taller (5°)
and more vigorous in every way than the others; leaves three-lobed,
with each lateral lobe again divided, and all the lobes variously gashed
and cut-toothed. The ample foliage, the long, hooked spur, acute sepals, the
distinct spur on the lower petals, so far as they go, make the limits of this
species in my collection tolerably well defined. Utah.

GO BOTANY.

AconituM Fiscuert, Reich. (A. nasutum, Fisch., of my list of 1874.)—
2-3°, smooth below, puberulent above; petioles of lower leaves 2—4’; leaves
round in outline, 3-5-parted, with each division deeply lobed or cut-toothed;
flowers in a loose raceme, pedicels 4-1’, pubescent, erect; petals, conical
galea, and flowers from blue to purple or even white. Grows abundantly
along mountain streams in Colorado. (98.) According to Mr. Watson, “A
small specimen was collected in Southern Nevada with an unusually nar-
rowed galea and long projecting beak.” Also collected in Utah.

Actaa spicata, L., var. arcuTa, Torr.—F lowers absent; pedicels vary
from less than a quarter to more than half an inch in length in the fully
formed fruit. There is no perceptible thickening of the pedicel with age,
and this I take to be the most reliable characteristic furnished by the fruit-
ing specimens.

Paonia Brownu, Dougl.—Nevada.

BERBERIDEZ.

BeRBERIS FENDLERI, Gray (Pl. Fendler. p. 5).—Shrub 3-6 °; branches
and branchlets smooth and shining, as if varnished; spines 3—5-parted; leaves
oblong-lanceolate, acutish, entire, or irregularly spinulose-serrate, entirely
glabrous ; racemes pendulous, 1—2’, and densely flowered, somewhat longer
than the leaves, which, however, vary much in size in adult condition; calyx
with conspicuous red bracts, which are a little shorter than the sepals.
Flowers yellow and as large as those of B. vulgaris. Unripe fruit with
2-3 seeds; blooms in May and June. I probably collected my specimens
from the exact spot at which Mr. Fendler obtained his. The shrub appears
to be by no meanscommon. Santa Fé, N. Mex. (54.)

BERBERIS REPENS, Lindl.—‘‘A low, somewhat procumbent shrub, less
than 1°; leaflets 8-7, ovate, acute, not acuminate, 1-24’, not shiny above;
racemes few, terminating the stems, 1-14’.—Bot Reg. t. 1176. B. Aquifolium,
Pursh, mainly, and of numerous authors.”—(F1. Cal. 1, p.14.) I have not
seen the species.

Berseris Aquirotium, Pursh.—Common in mountain parts of Central
Colorado. (57.)

Brerseris Fremontu, Torr.—Leaves pinnate, with 3-4 pairs of leaflets,

CATALOGUE. 61

the lowest pair of which is situated uniformly close to the insertion of the
petiole ; leaflets ovate, repand, spiny-dentate (In my specimens from
Southern Utah, the leaflets are hardly half an inch long. Torrey, how-
ever, in Bot. Mex. Bound. p. 31, states that the leaflets are from 1-24’.)
Racemes erect, 5—7-flowered, longer than the leaves; pedicels over half an
inch long; flowers golden yellow, half an inch in diameter; filaments inap-
pendiculate; berries large as currants. Its nearest affinity is with B.
trifoliata, but it has more leaflets, longer racemes, and blue instead of red
fruit. Arizona.

PAPAVERACE.

ArGEMONE Mexicana, L., var. nispipa, Torr. (A. hispida, Gray, PI.
Fendl. p. 5.)—Santa I'é, N. Mex., where it quite covers the vacant lots on
the outskirts of the town. Collected also in Utah.

CorypDAuis AuREA, Willd., var. occrpenTais, Engelm.—Like our East-
ern form of C. aurea, except that it has a longer spur, erect pods, and
lenticular seeds with acute margins. Apparently this is the more common
form from Colorado south along the main mountain axis. Sierra Blanca,
Arizona, at 9,000 feet altitude (813); Nevada, Prof. Loew; Santa Fé, N.
Mex. (55); and Colorado.

CRUCIFERA.

CuHEIRANTHUS Menziesu, Benth. & Hook.—Carlin, Nev.

NasturTIuM sinuATuM, Nutt—(618.) From San Luis Valley, on the
alkaline flats; leaves absolutely coriaceous, though beautifully and regu-
larly pinnatifid ; (625) is from Apex, Colorado; like the other, though with
much thinner leaves; (123) is from New Mexico, as is also (99), but which
has quite acute tips to the lobes of the leaves: has also been collected by
the Expedition in Nevada.

Nasturtium ostusum, Nutt.—Twin Lakes, Colorado. (617.)

NAsTURTIUM PALUSTRE, DC.—Twin Lakes, Colorado. (627.)

Nasturtium PALusTRE, DC., var. HisprpuM, Gray.—San Luis Valley,
Colorado. (626.)

ARABIS PERFOLIATA, Lam. (Turritis glabra, L.)—In the enumeration of

62 BOTANY.

1874, I had regarded this as an unusual form of A. hirsuta. Twin Lakes,
Colorado (650 )

AraBis Drummonpu, Gray.—South Park, Colorado. (655.)

Arasis Hotp@_iu, Hornem.—Common and variable. Colorado and
Nevada.

CaRDAMINE CORDIFOLIA, Gray.—1-2°. Generally erect, from a fibrous
root, which not unfrequently is in the water; leaves all petioled, cordate in
outline, irregularly repand-dentate or sinuate, sparingly ciliate; siliques
erect, twice as long as the pedicels. Common in Colorado at 10,000 feet
altitude, in swamps and mountain streams. (608, 609, 610.)

VesicartA Lupoviciana, DC.—Hoary throughout, with a stellate
pubescence, erect, 6-10’ high, usually branching; root-leaves spatulate ;
stem-leaves linear to linear-lanceolate, all obtuse; flowers yellow; petals
obovate, one-half longer than the sepals; pods oval, somewhat inflated,
rather shorter than the style; pedicels 6-9’ long. Colorado. (641.)

VesIcaRIA MONTANA, Gray.—Colorado. (647.) By some oversight, I
transposed the labels of these two species in distribution of the collection
of 1873.

PuysaRIaA DIDYMocARPA, Gray.—Alpine and sub-alpine in Colorado.
(642, 648.) The Expedition has it also from Nevada and Utah.

Dragpa atpina, L.—A very attractive little perennial found in Colorado
at 10,000 to 13,500 feet altitude; its favorite habitat being above timber
line. (646.)

Drapa aureEA, Vahl.—Pubescent, erect ; stem usually quite leafy; leaves
lanceolate, acute, entire or sub-entire; siliques lanceolate, acute, nearly
twice as long as the pedicels, hairy and more or less twisted; style $” long;
petals yellow. A very variable species, of extended range. The Expedi-
tion has it from Colorado, New Mexico (Loew 633 and 634); and from
the higher mountains of Arizona, the var. stylosa.of Gray (1111).

Drasa strEProcARPA, Gray.—Alpine in Colorado, along with aurea.
My specimens furnish a singular example of transposition of characters
usually reliable in distinguishing between these species; #4. e., aurea and
streptocarpa. The specimens which have the fruit most characteristic of
streptocarpa are in other respects most like (generally including length of

style also) aurea. I must, however, say that the fruit is in no instance so
much twisted as in the original specimens on which streptocarpa was founded.
That differences sufficient to constitute distinct species exist between the
extreme forms, no one will probably deny. It is equally certain that they
shade into each other until at times all tests are doubtful and justify a place
under either name. In this instance, I have named as streptocarpa all speci-
mens having leaves ‘beset and especially ciliate, with long and rigid,
shagey, spreading, simple or simply forked hairs, far more bristly than in
D. aurea, and with no fine stellular pubescence intermixed.” I rely more on
this character in deciding between interloping specimens than on any other.

Drasa rncana, L., var. conrusa, Hook.—I have from Colorado (num-
ber mislaid) a plant similar to herbarium specimens that are authentically
named, and that bear the above name.

Drasa montana, Watson.—‘‘Annual, hoary-villous, with simple or
branching rigid hairs, rather stout, erect, simple or sparingly branched
from near the base, becoming a span high or less; leaves rosulate and
rather crowded at and above the base of the stem, oblanceolate and oblong-
lanceolate, acutish, sparingly toothed, half an inch long or less; flowers
small, the yellow or yellowish petals 1-14’’ long, exceeding the sepals;
pods linear-oblong, obtusish, roughly puberulent, about 4” long, nearly
erect upon the spreading pedicels, which are 2” or 3” long; style none.—
Collected in Colorado by Hall and Harbour, without number; in South
Park by Wolf (637), and near Empire by Rev. E. L. Greene. It is distin-
guished from D. nemorosa by its stouter and less branching habit and its more
erect pods on stouter pedicels, and from D. stenoloba by its stouter habit,
greater pubescence, and somewhat broader and obtuser pods.” —Warson, MS.

Drapa nEMoROSA, L., var. LUTEA, Gray.—Georgetown, Colo. Stems
less leafy and pedicels shorter. (628.)

Numbers 635 and 636 of the Colorado collection I had named D.
nemorosa, L., var. crassifolia, Watson, from the resemblance to Draba crassi-
folia, Graham, in Hall and Harbour’s 1862 collection. Brewer and Watson
(Fl. Cal. 1, p. 28) speak of this, however, as having a naked and scape-
like stem, whereas my specimens are leafy. I therefore leave them simply
under D. nemorosa, 1.

This is a strikingly showy plant; stem rises gracefully to a height of 5 feet
often, and is crowned with a cluster of scarlet mottled flowers.

The lax, scattering arrangement of the leaves is in striking contrast to
the usually more crowded arrangement in EL. asperum. Judging from the
description in Flora of North Am. T. & G. p. 95, I should think its
nearest affinity would be JL. elatum, Nutt. MSS. Still it appears distinct
from this, all the more probably so, as the only points at which it was
taken were Camp Grant, Ariz., and Mount Graham, near by, but 5,000
feet higher, where it had developed some local peculiarities without bring-
ing it any nearer known species. The stem of the mountain plant was
more light, airy, leaves smaller and more numerous, and pods longer, but
with essentially the habit of the same species at the foot of the mountain.

I am loth to name a new Erysimum, for reasons which are apparent to
all who have studied the genus. Still, this seems too well marked a species
to pass it by.

Annual, stem erect, smoothish, or with a few scattering hairs; lower leaves
small, roundish, crenate ; stem-leaves long, petioled, thin, irregularly deeply
cleft or strongly halbert-shaped; flowers axillary, sky-blue, 5-3’ in diam-
eter (apparently resembling A. parviflora, Cav.). Calyx-lobes twice as long
as the tube and distinctly bristly hirsute. Much against my will, I am
obliged to retain this still as a variety, there being, so far as I can dis-
cover, little deviation from the typical form save in the size of the flowers.

From Camp Bowie, I have a form which is much more hairy, has leaves larger

AyentAt pusitua, L., var. ramis erectis, foliis superioribus lanceolatis,
Gray (Pl. Wright. 1, p. 24)—Perennial, with many thin, wiry stems from
the thick, woody root; lower leaves ovate and somewhat irregularly serrate,
upper ones irregularly serrate, twice as long, and lanceolate ; flowers small,
on reflexed, filiform pedicels, which are 2-4’ long; capsule tuberculated
and hairy. I would call attention to the fact observed by Dr. Gray (PI.
Wright. 2, p. 24), that the anthers are trilocular. Judging from the state-
ment in Bentham and Hooker, Gen. Plant. vol. 1, p. 225, this would also
appear to be the usual rule in the genus. My specimens (569) from South-
ern Arizona correspond exactly with those obtained by Dr. Thurber at Van

Linum Beruanprert, Hook.—Erect, annual, stem distinctly striated,
slightly puberulent; lower leaves obtuse, upper slightly mucronate, longer
on the average than in the preceding species, which it so closely resembles
that I know of no way of distinguishing them, save by the character of the
false dissepiments (as indicated by Dr. Engelmann in Pl. Wright. 1, pp. 25
and 26), which, in L. Berlandieri, are membranous in the upper and inner
half. Under head of LZ. Berlandieri, Dr. Engelmann alludes to a small form
collected by Wright on the San Pedro River, which is apparently kept apart
from L. rigidum, var. puberulum (collected on the Cimarron), only by the
character of the false partition in the ovary, which is decidedly that of L.
Berlandieri. I have the precise form (from Santa Fé) he alludes to (so
far as can be determined from description), and have, from its partitions
and ovate-triangular-based filaments, been obliged to put it under L rigi-
dum, var. puberulum. Single specimens found by Dr. Loew at Rancheiro

SIBBALDIA PROCUMBENS, L.—Colorado, at 11,000 feet altitude, (403).
Though Torrey and Gray (Fl. N. Amer.) state the only difference between

of the former, and though Bentham and Hooker (in Gen. Plant.) do actually
unite these genera, I have refrained from following so reliable authorities,
because Mr. Watson has excluded Sibbaldia, Horlelia, and Ivesia from his
revision of Potentilla. At the same time I do not hesitate to express my
opinion that the distinction between Potentilla and Sibbaldia will not stand.

Rises Wotrn, Rothrock (in American Naturalist, June, 1874). (RR.
sanguineum, Pursh, var. variegalum, Watson, King’s Report, vol. v, p-
100.)—2 to 4 feet high. Neither prickly nor spiny. Moderately branch-
ing. Young branches light brown, minutely glandular-pubescent, some-
what angular by two ridges continued from the edges of the expanded
bases of the petioles above. Branches of the previous year ashy-gray,
with a deciduous epidermis, which, on being shed, shows the bark under-
neath dark brown.

Leaves cordate-orbicular, deeply 5-cleft; lobes rather obtuse, unequally
serrate, though hardly doubly serrate (average diameter of the largest leaves
2 to 23 inches; depth of sinus at base in largest leaves 4 inch), slightly
viscid; under surface with a few glandular hairs, pale green; upper surface
smoother and deeper green; petioles in fully developed leaves from 1 to 14
inches long, margined by a continuation of the veins of the blade, expanded
at base and becoming semi-amplexicaul, frequently strongly pectinately
ciliate and glandular.

Peduncles 1 to 2 inches long, decidedly glandular-pubescent, 4- to 10-
flowered; bracts ovate-spatulate, obtuse, yellowish-white (oceasionally
verging toward red), 1 to 1} lines long and 1 line shorter than the pedicels,
which are a little longer than the flower.

Sepals red, lanceolate, obtuse, 14 lines long, never reflexed; petals red,
ovate-spatulate, half as long as the sepals, equalling the stamens; styles
two, distinctly conical from the top of the ovary, red for half their length,
parted to or below the middle, recurved; stigmas slightly capitate.

CATALOGUE. 119

Young fruit strongly glandular hairy, but never prickly, becoming
smoother with age; mature fruit maroon or reddish-purple, globose, three-
eighths of an inch in diameter, few- to many-seeded, edible; seeds dis-
tinctly wing-margined, with the inner coat, as seen through the gelatinous
covering, longitudinally dotted.

It will be seen that this plant approaches both &. glutinosum, Benth.,
and It. sanguineum, Pursh, though its nearer affinity is with the latter. It
is distinguished from the former in being fewer-flowered, having shorter
racemes and a rounder berry, and from the latter by its shorter racemes,
relatively shorter bracts and longer pedicels, and erect calyx-lobes. It
may prove to be a mere variety of I. sanguimewm, though I think it suff-
ciently distinct to bear the name of its zealous discoverer, Professor Wolf.

nodding in the bud; seeds not seen. In this and the next species, there is
a great difference in the length of the styles in plants from the same imme-

to regard it as G. Drummondii. I believe it will prove distinct from either,

GauRa PARVIFOLIA, Torr. (in Ann. Lyc. New York, 2, p.200). (G@. coccinea,
Nutt., var. of T. & G.)—Perennial, much branched from the base; branch-
lets, leaves, and fruit hoary puberulent; leaves 4-3} long, linear, irregu-
larly and sparingly denticulate ; calyx-tube 3-5” long, a little longer than
the lobes; stigmatic indusium deeply 4-lobed, and slightly folded around the
lobes of the stigma; appendages to the filaments rather large, 1’ long;
mature fruit suddenly contracted into a thickish neck at its lower third,
above acutely 4-angled, intervening faces deeply concave, apex obtuse,
acute, or even apiculate; style at base slightly villose. Evidently the
nearer affinity of this plant is with G. coccinea, but since in addition to its
smaller leaves the stigmatic indusium is constantly 4-lobed, I feel bound
to keep up the distinction and restore the old name. ‘The bracts too are
smaller than in G. coccinea, and not caducous as in G. Drummondii, to which

Mamitiaria (Coryrpnantua) vivipara, Haworth, Engelm. in Watson’s
Bot. King’s Expl. 117—A common plant on the Western plains from the
Missouri to Texas, extending in the mountain regions as far west as Arizona
and South Utah, the large, deep rose-colored or purple flowers, with fringed
sepals and lance-linear, acuminate petals, green, oval berries, with light
brown, pitted seeds, readily distinguish the species. The form of the plains
is lower and often densely cespitose-spreading; the mountain plant is often
simple and larger. The largest form, which comes from Arizona, I had at
one time distinguished as MZ. Arizonica, but must now consider it as only a
gigantic vivipara, 3-5’ high, 4’ in diameter, with spines often over 1’ long
on rather broad and spreading tubercles. Rothrock, 1874, (203), is asmaller
form, from Camp Apache, Ariz.

Mamiuyaria (CorYPHANTHA) CHLORANTHA, n. sp.—Similar to the last,
but with broader yellow petals; stems oval to cylindrical, 3’ wide, some-
times 8-9’ high; tubercles compressed from above; 20-25 outer spines gray,

o, reddish or

almost in 2 series; 6-8 or 9 inner ones stouter, $-1’ long,

brownish only at the tip; flowers yellowish or greenish-yellow, crowded on
the top of the plant, 14’ long and wide, often 1-2 small, fringed sepals on
the ovary (which also occasionally is seen in vivipara); sepals lanceolate,
fringed; petals lanceolate or linear-lanceolate, acute, denticulate; 7-9
whitish stigmas, erect-spreading.—Southern Utah, east of Saint George, Dr.
Parry. I. E. Johnson.

Ecutnocactus Wis.izeni, Engelm.—Very large, often over 3° high
and half as much in diameter; at first globose, then ovate to cylindrical,

and many-seeded. Seeds ovate or oblong. Stems annual, roots perennial, often procumbent and rooting.
Leaves cordate at base and lobed. Tendrils 2-many-cleft. Flowers large, yellow. Fruit often very
large.—BENTHAM & IIOOKER.

with 21-25 rather sharp ribs; the large linear-oblong areola (very woolly
when young) bear three kinds of spines, first, 4 very stout, annulated, reddish
ones, 14-23’ long, the 3 upper ones straight, the lower one hooked; second,
3-5 lower and usually 3 uppermost spines, slender, but straight, stiff, and
annulated, of reddish color; third, 12-20 whitish, bristle-like, flexuous,
lateral spines: flowers 2-23’ long, 15 wide, yellow, outside greenish with
purple-brown; ovary and fruit imbricately covered with numerous (50-60)
cordate or reniform crenulate sepals; sepals of tube oblong, ciliate; petals
broadly linear, crenate, bristle-pointed; style deeply divided into 12-18
linear stigmas; seeds 1’ long or over, reticulate or shallow-pitted Southern
New Mexico.

Var. Le Coxtet (£2. Le Contei, Engelm.)—At last clavate from a slender
base; lower central spine more flattened, curved or twisted, but not hooked;
flower rather smaller and with fewer parts—This is the Western form, from
South Utah and Arizona to and beyond the Colorado River. Dr. Rothrock
collected, at Camp Bowie, Ariz., a peculiar form (492), which may repre-
sent another variety, decipiens: globose, 1° in diameter; spines shorter and
fewer, no straight spines above the 4 central ones, none longer than 1-14
inches; 10-15 thin flexuous spines on side and upper end of areole; only
20-25 sepals on ovary.

Fé, 1874, Rothrock (39). C. gonacanthus, Engel. & Bigel., which extends
from New Mexico to the Arkansas River and westward to Zuii, and is
characterized by its stouter, longer, and more numerous spines, may
belong to this species; and perhaps both, with numerous other so-called
species, which vary only in the number of the ribs, the number or form of
the spines, and the closeness of the spine-bunches, but have all similar
flowers, may have to be considered as forms of one polymorphous type
(C. pheniceus).

OpunTIA (PLaTOPUNTIA) BASILARIS, Engelm. & Bigel—A low plant,
with broadly obovate, often retuse or fan-shaped joints, branching mostly
from the base, pubescent, as well as the fruit; areole very close, without
spines, but densely covered with short, yellowish-brown bristles; flowers
large, rose-purple; fruit dry, subglobose, with rather few, large and thick
seeds.—Southeastern California to Arizona. Distinct from all other species
of this region by its mode of growth, its pubescence, the absence of spines
proper, and the very large (34-5’’ wide) seeds. The large purple flowers,
which in the season completely cover the plant, make a beautiful show.

to preserve and flowers and fruit have not often been found or collected.
Full notes, living joints, good fruit and seed, and pressed flowers are
desirable, to make us sufficiently acquainted with these plants. The best
method of preserving the flowers is to split them open before attempting to
dry them. Living plants or joints are very valuable, but alone are not
sufficient, because in cultivation they very rarely flower and scarcely ever
bear fruit.

OpunTIA (CYLINDROPUNTIA) CLAVATA, Engelm.—A low, cespitose plant,
with short (1-3’ high, 1’ thick), clavate, ascending, strongly tuberculate
joints, the upper areole bearing 4-7 ebony-white, flattened, striate spines,
surrounded by a number of smaller, bristly ones; yellow flowers, 2’ wide;
dry, yellow, oval pod, covered with numerous, large, woolly, and long-bristled
areolee.—E] Rito, New Mexico, Rothrock, in 1874 (92). Also about Santa

OpunTIA (CYLINDROPUNTIA) PULCHELLA, Engelm. (see Watson’s Bot.
King’s Expl. 119; Simpson’s Report, Botany, t. 3).—A very small, purple-
flowered species of Nevada. <A flower brought home by Mr. Bischoff was,
by a singular error, enumerated in the Catalogue of 1874 as Cereus viridi-
florus.

OpunTIA (CYLINDROPUNTIA) ARBORESCENS, Engelm. (see Watson, J. ©.
120).—Cuero, New Mexico (101), Rothrock, in 1874; Cienega, South Arizona
(near Tucson), the same (584); and from Camp Bowie, Ariz. (1002), by
Mrs. Major Sumner. This handsome species extends northward to the
plains of Colorado and Pike’s Peak, covering extensive tracts. Remark-
able for its horizontal, often whorled, branches; purple flowers, 2-24’ in
diameter; ovary often with some spiny bristles, which at maturity disap-
pear. The skeleton, as the cactus wood is rather fancifully called after the
soft tissues have rotted away, forms a heavy, hollow cylinder, with regular
rhombic holes or meshes corresponding to the tubercles and spine-bunches
of the plant, and makes excellent canes. This species is closely allied to
the Mexican O. imbricata and O. decipiens, arborescens being the northern,
larger-flowered form, but the seeds are different.

Opuntia (CyLinpropuntiA) BicELovir, Engelm. (Pac. R. R. Rep. 4,

CATALOGUE. 131

Rot. 50, t 19)—An erect, bushy plant, 10-12° high, with oval or sub-
cylindric joints, bearing on short oval tubercles 3-5 large (1’ long) and
many smaller spines, the larger ones loosely covered by glistening, whit-
ish sheaths; purple flowers, small, 1 inch wide; fleshy, greenish berry,
numerous small and very irregular seeds, or often abortive; wood a wide,
fragile tube with short meshes.

Opuntia (CYLINDROPUNTIA) TESSELLATA, Engelm.—Very bushy, from
a stout trunk, with solid wood, sometimes several inches thick; ultimate
branches as thick as a swan’s quill, covered with angular, flattened, ashy-
gray tubercles, the uppermost bearing at their upper end single, long, loosely
yellow-sheathed spines; flowers small (about # of an inch wide), yellow;
small fruit, oval, covered with long, soft, brown bristles. Pac. R. Rep. 7. c.
t. 21.—On both sides of the Lower Colorado River, 6—7° high; the yellow,
shining spines, crowded on the upper end of each year’s growth, together
with the scale-like tubercles, give the plant a singular and striking appear-
ance.

There are several other cylindric Opuntia in Arizona, not collected in
these Kxpeditions, and for the most part only imperfectly known. It is
desired to direct attention to this interesting group, which, on account of the
bulky forms and forbidding armament, are too much shunned by travellers.—
Opuntia echinocarpa, Engelm. & Bigel., is a low and very spiny bush, with
yellowish flowers and dry, spiny fruit. Opuntia acanthocarpa, Engelm. &
Bigel, is taller, with elongated tubercles, or rather ridges, copper-colored
flowers, and dry fruit bearing few, but stouter spines. O. mamillata,
Schott, and fulgida, Engelm. & Bigel., are allied to O. Bigelovii, with
thick tubercles or prominent crests, the former with small, the other
with numerous long and shining, sheathed spines; fruit often abortive.
Good specimens with flower, fruit, and good seed of the same plant
(so that mixing species and forms may be avoided) are very desirable,
as we know scarcely anything more about them than what the botanists
of the Mexican Boundary Commission (often at the most unfavorable season)
could find out, twenty-five years ago. Opuntia leptocaulis, DC. (0. frutes-
cens, Iingelm.), the most slender Opuntia known, bushy, with branches like
pipe-stems, small yellow flowers, and red, somewhat fleshy berries, is common

flowers, contrary to the habit of the genus (which has diurnal flowers—i. e.,
open in sunlight), are nocturnal, which, however, is now positively denied.

sure that the specimen may not prove to be G. Aparine, to which it appears
closely related. If so, then it must be truly indigenous.

Corolla narrowly tubular—Sanoita Valley, Arizona (607). So far as any
mere description goes, this plant answers better to S. serrata, Cav. in Prod. v,

Professor Gray, I cannot doubt it is correctly placed under the latter name.

this species, I can recognize var. hispida, Gray, which is best marked, with
its leaves lanceolate and acute, or spatulate, oblong and obtuse, from #—1’
long; plant hispid, with short, stiffish, and more or less dense hairs. (555,
464, from Colorado, 792 from Arizona, and an unnumbered one collected by
Loew in New Mexico; var. foliosa, Watson, more leafy, with leaves obovate-
spatulate, 1’ long, and more or less canescent, running into C. canescens, T.
& G. (791, 182, from Arizona, and 552 from Colorado). Canescent form
(724) from Southern Arizona is well marked.)

This plant, from its general habit, clearly justifies Bentham and Hooker

It is evident that this plant is near to S. edora, Ait., but it appears to
differ in its leaves and in the obtuse scales of the involucre, as well as in
the larger number of flowers (of both kinds) in the head, and in the
absence of the characteristic odor of odora. I name it in honor of Lieut.

AsTER ADSCENDENS, Lindl—Twin Lakes, Colorado, at 10,000 feet,
(522); also from Utah. Var. crmiatiro.ius, T. & G., stems with many linear
leaves (1-3’ long and 1-3” wide), somewhat ciliate; scales of the involucre
ciliate, acutish ; upper part of the stems rather hispidly pubescent.—Cotton-
wood Creek, Colorado (524). The leaves are in the main narrower and
the scales of the involucre less acute than in 252 of Hall and Harbour’s
collection, with which my 509 more nearly compares. Number 492 of our
Colorado collection is a slender, almost leafless state, with smaller rays and
more acute tips to the involucre than the typical var. ciliatifolius. 523 ap-
proaches A. falcatus, Lindl. Number 525, marked by Dr. Gray as a curious
form, is, except for its smooth involucral scales, very much like A. integri-
folius, Nutt. (No. 6166 of Bolander’s California collection), and so like the
description of A. adscendens, var. Parryi, Eaton, that I am constrained to
leave it there, and hence will probably be A. adscendens, Lindl. (?) (as con-
sidered by Dr. Gray in Fl. Cal. 1, 324); from Colorado. A specimen of
adscendens, however, collected by me at the Soda Spring, on Kern River,
in California, is like 525 in the involucral scales, but with much narrower
leaves. Except this one from California and the one from Utah, all my
material is from Colorado, at or above 10,000 feet altitude.

‘Span high, with many ascending, rigid, somewhat hispid stems from a
subligneous root; branches monocephalous, corymbose-paniculate ; leaves
small, rigid, entire, linear, coriaceous, sessile, mucronulate, smooth and
single-nerved, with the margins hispidly ciliate; the lowest subspathulate,
and the upper very short; involucre campanulate, scales in 3 series, linear-
oblong, glandulose-scabrellate, mucronulate, the exterior herbaceous ones
obtuse and lax, the interior a little longer, acute; achenia pubescent.” (510.)

Aster Dovexasi, Lindl. ?—San Luis Valley, Colorado (500). Scales of
the invoiucre narrowly lanceolate, very acute, with a narrow chartaceous mar-
gin; leaves 2-4’ long, 2-5” wide, with the margins distinctly hispidly ciliate.

ASTER SALsuGINOosUS, Richards——(486, 520, 516, 504.) From Colo-
rado, and all good representatives of the species. Number 521, however,
differs widely in appearance, both in the dried and living states, from the
others, and might even by many be regarded as a distinct species compared
with 516 and 520. It is shorter, much more leafy, with the scales of the
involucre oblong, obtuse, and almost smooth, exceptonthe ciliate margins; the
rays are wider, shorter, and more deep purple, to say nothing of its having
a broader and smoother achenium. I do not, however, regard it as even a
good variety, for all (516, 520, and 521) were obtained from a single clump
in a cool, shady location at 11,300 feet, on Union Creek Pass, in Colorado.

ASTER PAUCIFLORUS, Nutt.—Stem erect, simple, 1-2° high, smooth
below, puberulent or viscidly puberulent above; stem-leaves linear, 2-6’
long, 1-2’ wide, indistinctly 3-nerved; entire margins thickish and smooth,
becoming gradually reduced to subulate bracts above; heads few, terminat-
ing the branches, 3-5’ in diameter; scales of the involucre in about three
series, acutish, viscidly puberulent; rays purple, twice as long as the disk-
flowers; pappus light-colored, almost in a single series and nearly as long
as the disk-flowers.—San Luis Valley, Colorado (508).

ASTER spInosus, Benth—Stem much branched, glabrous, striate, sub-
angular above and terete below; leaves few, scattered, and reduced to
subulate scales, 1-3” long; heads solitary (rarely racemose), terminating the
branches; scales of the involucre not longer than the disk, in three series,
acute, and with scarious margins; achenia glabrous—A most peculiar-
looking plant extending across the southern part of the continent, from
Texas to California; Southern Arizona (769).

*“DIPLOPAPPUS ERICOIDES, T. & G.—To save labor to some others who, like myself, work under
the double disadvantage of a rather limited library and an herbarium (rich enough in the later new species)
with but few specimens from the original sets made prior to 1862, I put the following in print. From
our present standpoint it is evident that Diplopappus as formerly understood must be partitioned out
among other neighboring genera, and of the species that concern us here, one goes to section ERICAME-
RIA of Aplopappus, and the other to section ORTHOMERIS of Aster. In the unavoidable changing of
pames a confusion arises under the name above given, i. e., Diplopappus ericoides, there being two plants
that bear the name in herbaria and books. The following may in some sense clear up the matter:

Diplopappus ericoides, T. & G. Eucephalus ericoi- Diplopappus ericoides, Less. Aplopappus ericoides,

des, Nutt. ‘Inula? ericoides, Torr.! in Ann. Lyc. DC., and apparently also of Hooker and Arnott.
New York, 2, p. 212. Chrysopsis ericoides, Eaton, See DC., Prod. V., p. 278; Bot. Beechy, p. 146; and
Man. Bot.” F]. Cal. I., p. 313.

Now placed in Aster under Sect. ORTHOMERIS.
As the name ericoides is preoccupied in this genus
I suggest for it Aster ericwfolius, which indicates
even more closely its general habit.

See also Diplopappus ericoides, T. & G., Vol. V.,
King’s Report; Pl. Wright., p. 78; Pl. Fendl., p.
69; Bot. Mex. Bound., p. 78.

In the last, Ericameria microphylla, Nutt., is also
cited as another name for the same, and by this it
appears in Flora of North America, T. & G., 2, p.
236.

The two plants are so different in habit,—the one suggestive of (so far as arrangement of the

foliage goes) Hrica, and the other of Adenosloma fasciculatum, Hook, & Arn., or of Eriogonum fascicu-
latum, Benth.—as well as in habitat, that any further description is unnecessary.”—Botanical Gazette,
January, 1877.

ERIGERON ARMERIZFOLIUM,* Turez. (L. lonchophyllum, Hook. in Bot.

slender petioles; stem-leaves sessile, linear; inflorescence corymbose or
racemose, with a single head terminating a branch; scales of the involucre
lax, hardly in two series, acute, and the purple tips often taper-pointed;
achenia cylindrical, hairy; pappus with few or no smaller bristles inter-
mixed; rays very narrow, longer than the involucre—Twin Lakes, Colo-
rado (527).

a simple and wholly deciduous pappus, and its achenium is tipped with a
broad and white epigynous disk.” See Gray, in Proc. Amer. Acad. vol. viii,

puberulent; lowest leaves spatulate or oblanceolate, narrowed to a petiole;
upper leaves linear, sessile, 4-7’ long; heads terminating the erect branches,
which are naked near the summit; scales of the involucre linear, acute,
with scarious margins; ligules slender, very numerous, white or slightly
rose-colored; pappus in (both ray- and disk-flowers) two series, the exterior
short, squamellate, the interior longer.—A well-marked species, readily recog-

marked, with a few longer bristles intermixed; achenium with a distinct
epigynous disk, somewhat flattened (sometimes with distinct marginal and
facial ribs, as in Macheranthera)—Mount Graham, Arizona, at 9,000 feet
altitude (731). Number 500, from Camp Bowie, Ariz., appears to be the
canescently hirsute variety alluded to in Botany of Mexican Boundary, p.
78. In my specimen, the leaves are also much more finely divided toward
the summit (to say nothing of some difference in the achenia) than in the
typical form. I think this might be safely regarded as a distinct species.

Ericeron Covutrert, Porter—In absence of sufficient material, I am

single head, smooth below, pilose-pubescent above, leafy to the top; leaves
thinnish, pubescent, with ciliate margins, all more or less serrate-denticu-
late, mucronate, erect, gradually diminishing in size upward; lower ones
oblong-spatulate or elliptical, taperimg into a margined, ciliate petiole,
upper ones oblong or lanceolate, acute or acuminate, sessile, and partly
clasping; head large 1-2’ broad, including the numerous white rays; in-
volucre about 9” broad, hemispherical, densely pilose, but scarcely woolly;
scales lance-linear, with scarious margins, tips elongated, subulate, spread-
ing, glandular; achenia pubescent; bristles of the pappus minutely
scabrous, outer ones short and few; alveoli of the receptacle rough with
lacerate margins.” In my specimen, the plant is almost glabrous through-
out, except the scales of the involucre, and the leaves are barely denticulate;
flower also was purplish. In my preliminary report, I published this (519)
as ‘EF. macranthum verging toward grandiflorum”—Union Creek Pass,

scarious margins; rays over a hundred, narrow, purple; achenia slightly
hairy, distinctly ribbed; outer pappus present, but not evident—Western

perfect specimens may have enabled those authors to place P. filipes under
P. Taliscana with certainty. Dr. Gray, FI. Cal. 1, p. 400, still considers
them distinct.—Southern Arizona (539) In one specimen, I find three
awns to the disk-flowers, which alternate with three scales, each half as

villous ferruginous tuft”). This and the above species often closely resem-
ble one another in the flowers. Indeed, in a specimen from the Laramie

more like that of G. pulchella (which, from the unbranched stem and pin-

cone is clearly defined, but in some of my Southern forms of what I ean
only consider as multiradiata that it is also slightly present—i. e., the style
branches are not absolutely truncate. Whilst in the main I can recognize
marked differences between these two species, the wide range of variation
in the rays, size, branching, etc., makes me regard the differences as in the
highest sense simply one of degree. It is noteworthy, too, that these two
forms appear to come nearer to each other as we go southward.

GENTIANEZ.

By Dr. GEORGE ENGELMANN.

ERYTHRZA CALYCOSA, Buckley; Gray, Synops. 115.—Simple or branch-
ing from an annual or biennial base; erect stems quadrangular-winged;
leaves linear-lanceolate (about 1’ long), lower ones broader, as long or longer
than the internodes; panicle rather contracted, loose-flowered; pedicels as
long as or longer (or the upper ones shorter) than the large flowers (8—10”
in diameter, rose-colored, with yellow centre); calyx about the length of
the flower-tube; lobes of corolla oblong, acutish, often denticulate, scarcely
shorter than their tube; seeds small, 0.3-0.4"™ long.

In the Gila Valley, Rothrock, 1874 (325), and southeastward into
Mexico, Gregg, ete.—Stems 1-14° high, the tallest of our species; leaves
1-14’ long, distinguished by its large bi- or tri-colored flowers with acutish
lobes. £. venusta, Gray, with which it has been confounded, is a smaller
plant with larger deeper-colored flowers, broader obtuse corolla-lobes, and
usually longer anthers and larger seeds—The anthers of the different species
of Erythrea are of different shape and size, from orbicular and oval to oblong
and linear and 4-4 or 5™™ in length; all become at last spirally twisted
after they have shed their pollen, the longer more conspicuously so, the
shorter much less. The stigmas of this genus have often been misunder-
stood, probably because mostly observed in dried and pressed specimens.
They are never capitate or funnel-shaped, but always bilobed. Before
maturity, they remain closed, and only after the anthers have shed their

-pollen do both halves separate and spread out, just as the Gentians behave.

In the form of the stigma, I find valuable characters for erouping of the
species, and especially for the distinction of the American ones from those
of the Old World. ‘The stigmas of the former are flabelliform and broader
than long; those of the latter are orbicular-ovate or oblong to linear;
shortest in H. spicata and linearifolia, and longest in major, where they are
twice as long as wide, and in maritima, in which the length is 3 or 4 times

as great as the width. 2. Australis from Australia, as well as Cicendia
from Kurope, have stigmas like the American species, but ZL. Chilensis (at
least a specimen collected by Ochsenius in Valdivia, which I refer to that
species) differs from all the others in having elongated, cuneate, emarginate
stigmas.

The seeds of Erythrea are identical with those of a large group of
Gentianea, which comprise perhaps all of Grisebach’s Chironiew and Chlo-
re@, being very numerous and very small, from ; to scarcely more than
3" in the longer diameter, and, when fully mature, globose or oval, with
their surface favose-reticulate.

The North American genera belonging to this group may be arranged
thus :

1. Stamens inserted in the tube: Eryrurwa. Evstoma.

2. Stamens inserted in the throat: Sapnatia. Muicrocat.a.

Criora, Curronia, and Sepa of the Old World also belong here.

My investigations have convinced me that the genus Cicendia, or at
least its typical and original species, C. pusilla, is nothing but a reduced
form of Erythrea, distinguished from it only by its small oval anthers, less
than 0.5™" in length, too short to twist much, but still, when drying, some-
times twisting a little. Its stigma is by no means capitate, but regularly
bi-lamellate, and, much like that of the American species, triangular-flabel-
late, and broader than long. The flowers are 4-parted, which often occurs
in genuine species of Erythrea; seeds 0.4" long, large for the size of the
plant. It will have to bear the name Erythrea pusilla.

ErytHraa Doueiasu, Gray, Fl. Calif. 1, 480; Syn. 113.—Slender,
a span to a foot high, loosely and paniculately branched, usually sparse-
flowered; leaves from oblong to linear, acutish; flowers on strict, slender
pedicels, 4-5’ wide; lobes of the pale pink corolla obtuse, much shorter
than the tube; anthers usually only 1™™ long, style short, stigma about
1™" wide; seeds sub-globose, 0.4™ in diameter.—Arizona, Utah, and
northwestward to Oregon. This plant has been confounded by Mr. Watson
with his 2. Nuttallii, which, however, is a smaller and more leafy plant,
with larger flowers and much larger seeds (0.65"" long), but much smaller

stigmas.

GENTIANA* HuMILIS, Stev. Griseb. in DC. Prod. 9, 106. Engelm.
Trans. Acad. St. Louis, 2, pl. 9, figs. 1-5. Gray, Syn. 120.—Biennial, with
large, broadly oval, rosulate, white-margined basal leaves, and few or many
ascending stems of a pale yellowish-green; cauline leaves small, linear-
oblong; flowers single, terminal; corolla greenish or whitish, 4-6’ long,
tubular, with acute lobes, and short, notched folds; anthers oval, introrse;
capsule clavate-obovate, on a long stipe, usually much exceeding the corolla;
seeds oblong.

Wet, grassy spots in the higher Rocky Mountains; also in Asia.
The long, protruding capsules (trumpet-shaped when open), together
with its pale, sickly look, give the little plant a very curious ap-
pearance.

GENTIANA PRosTRATA, Henke; Griseb. 1. c. Engelm. /. c. figs. 9-14.
Gray, Syn. 120.—Annual, small, weak, 1-2’ high, with horizontal or decum-
bent branches; leaves only 2-3’ long, ovate, green with narrow white
margins; flowers azure-blue, 4-parted, terminal on the branches, 5-6’ long
(or in luxuriant specimens sometimes larger); lobes ovate-lanceolate;
appendages half as long, similar or sometimes notched; anthers oval,

*The presence or absence of folds or plaits between the lobes of the corolla and the mode of
attachment of the anthers to the filament separate the Gentians into two large and very natural sec-
tions, already recognized by old authors: Gentianella (Bor khausen ), Gray, has a corolla without folds and
the anthers versatile; Pneumonanthe (Necker), Gray, has a corolla with folds between the lobes and fixed
anthers. It will not be useless to explain the term versatile in respect to anthers, as many seem to mis-
understand it, so that they speak of versatile anthers as accidental and unconnected with a physio-
logical process. The fact is that in Gentianella the anthers are introrse in the bud and after it first opens;
but as soon as the flower is fully expanded (generally toward the middle of the day) the anthers gradu-
ally assume a horizontal position (the notched base raised and turned toward the as yet immature and
closed stigma), open the cells upward, and begin to shed their pollen. Toward evening, the now effete
anther is turned over backward, and on the next morniug we find it hanging on the back of the fila-
ment, the notched lower end turned up and the empty cells directed outward. Thus in about twelve
hours it has described an almost complete circle. In my figures of Gentians in the Transactions of the
Academy of Saint Louis, vol. 2, pl. 7, 8, 9, and 11, versatile anthers are erroneously represented as turn-
ing indiscriminately outward orinward. This is a mistake, as the above account of the living action of
the anthers shows. In the figures of G. humilis and prostrata, pl. 9, the anthers are also figured as ver-
eatile in that unnatural manner, while in these species they are constantly erect and introrse, as well
before opening as when effete.

In Pneumonanthe the anthers remain fixed in two forms. In one section, comprising mostly smaller
plants, with smaller flowers (G. prostrata, verna, Altaica, humilis, wtriculosa, etc.), they are introrse. In
another section, the true perennial large-flowered Pnewmonanthes, to which we must add also an annual,
G. Douglasiana, and the European G. cruciata, they are extrorse. In the genera Halenia, Pleurogyne,
Swertia, and Frasera, all represented by plants collected in these expeditions, we find the same arrange-
ment of versatile anthers as in Gentianella. It therefore seems proper to enumerate, first, the Gentians
with fixed anthers, and next those with versatile anthers, and then, joining them, the other genera with
similar versatile antheral arrangement.

long as the corolla, with subulate lobes and, frequently, a cleft tube; flowers

spotted with red and brown; lobes broad-triangular, acute; reddish plaits
wide, oblique, undulate-crenulate, almost entire; anthers free; seeds broad,
narrowly winged, with crested ridges.

Springy places, in the alpine regions of the Rocky Mountains, and in
Asia; very rare in EKurope—aA very handsome plant in the color of its
flowers. Its mode of growth is entirely different from any other of our
species. The flowering stems bear in the axils of their lowest leaf-pair,
within its long sheath, or breaking through it, leaf-buds which in the
succeeding year produce flowering stems, while the base of the old stem
withers away. The roots are therefore only of one year’s growth, thin
and filiform, never thick, as those of most other Pneumonanthes, nor is
there a real caudex.

The numerous thin seeds are borne on the whole inner surface of the cap-
-sule, which thus not only has the function of a placenta, but really seems
to be nothing but a thin, membranaceous expansion of the placente them-
selves, forming a free sac within the capsule, which originates from the
commissures of the carpels, and remains attached to them only, and is at
last otherwise entirely unconnected with the walls of the capsule. It is
probable that all the Pnewmonanthes with ovules from the entire inner sur-
face of the capsule have this structure, and that in the others the ordinary
arrangement of commissural placente prevails.

The Norwegian specimens of this plant in my herbarium have much
smaller flowers than ours and much smaller seeds. The “scales” which
roughen the surface of the seeds prove, when moistened, to be transparent
vesicles, single protruding cells of the epidermis. In the Norwegian form,
these vesicles are small, oblong, or cylindric; in the American specimens,
they are much larger and mostly hemispherical; in the allied G. crinita, I
find them large and oblong.

11.—Has thus far been found only in the mountains of Colorado, near the

founded with serrata or simpler. I have already, in the first account of this
species, given the diagnostic characters, and have also stated that it is the

only perennial one of the section Crossopetalum in America, somewhat allied

to the European G. ciliata, also a perennial species, which used to be claimed
as an annual; barbellata, however, has seeds similar to those of serrata, though
much smaller, while ciliata has the winged seeds of simplex, and has an indefi-
nite number of leaves. I have since had the opportunity of studying barbel-
lata in the mountains of Colorado, and found that it possesses a creeping,
filiform rhizoma, 2—3 inches below the surface, from which at intervals filiform
stems arise. These bear, at their thickened upper end, where they reach
the surface of the soil, an undeveloped terminal bud of indefinite growth,
and lateral annual flowering stems, the scars of which, enveloped by
withered leaf-bases, can be traced sometimes for five or six years back.
The vegetation of the plant is accomplished in the following manner.—Each
season the terminal bud developes two pairs of basal leaves; from the axil
of one of the outer leaves, the single flowering branch originates. Inside of
the two leaf-pairs just mentioned, we find a third and a fourth pair unde-
veloped, about half an inch long, which are to grow into the basal leaves in
the following season; and within these the four leaves of the next succeeding
season, now only half a line long, are already preformed. The flowering
branch, usually 3 or 4 inches high, normally bears one pair of leaves in
the middle, and a second involucral pair just below the almost sessile
flower; the four sepals are opposite these four leaves, and the four corolla-
lobes alternate with the sepals, and so on. In the axil of one of the third
pair of basal leaves preparing for next year, usually alternating with, or
sometimes opposite to, the present flowering branch, the bud of next year’s
flowering apparatus is already four lines long; it shows plainly the two
pairs of leaves and the calyx, and, in a very rudimentary state, also the
corolla. Thus each year’s vegetation exhibits at the flowering period
(August and September), on the primary axis, two pairs of leaves for the
present, two pairs for the next, and two for the third year, a secondary
axis with two leaf-pairs and the flower, and another preformed secondary
axis with the rudiments of the same organs for the next year. No other
Gentian has, as far as I know, such a typical growth, with the regular
preformation of all the organs, but we find the same among other plants in
other families, a striking example of which is furnished by our Nelumbium.
The regularity in our Gentian is not as absolute asin Nelwmbium ; for occa-

Moist, grassy places in Colorado, sometimes in large patches, and

next two genera afford the best opportunity of observing the action of the
versatile anthers as they slowly turn from the introrse to the horizontal, and
then to the extrorsely reversed position, as explained above. The glands
on the base of the corolla-lobes are distinct enough, but the surrounding
scale is apparently not, as it is ignored by many botanists; I have seen
it variable, longer or shorter, but always present; when fully developed,
it forms a complete crested or fringed funnel The stigma of this plant is
most peculiar, formed as it is directly on the commissure of both carpels
and representing a broad stigmatic line commencing about #” below the non-
stigmatose apex, running down the sides to the same distance above the base,
so that we have here a two-carpellary ovary with two lateral, but without
any apical stigma. This line is beset with elongated stigmatic cells or
papilla about 0.1™ long and j as wide. At the proper time, numerous
pollen-grains are found adhering to the stigma, many of them developing
their tubes. The seeds I have been able to examine were not fully

a goodly number of specimens of Gilia aggregata, Spreng., from different sta-

tions in the Rocky Mountains and California, brings to light a character in
the species which has been overlooked,—the unequal insertion of the stamens,
The degrees of variation in this respect are remarkable and so gradual as
to rule out the supposition of dimorphism. In the extreme cases, they are
included, on the one side, in the tube of the corolla and very unequally
inserted at points wide apart, from the base upward, whilst, on the other, they
are crowded toward the throat and more or less exserted. Then, the inser-
tion sometimes is, or rather, perhaps, appears to be, equal. In a specimen of
this kind from California, it would be hard to declare that the filaments in
some of the flowers do not start out from the same horizontal line, whilst in
other flowers on the same stalk their insertion is decidedly unequal. Now, as

the main character which separates Collomia from Gilia is the unequal inser-

tion of stamens, I have ventured to transfer this species to the former genus,
where it naturally falls into Dr. Gray’s section Phloganthea, and forms a link
of transition between the two genera. It may be here remarked that the
character of Gilia given by Bentham and Hooker (Genera, 2, p.822), ‘“semina
nunquam spirillifera”, is evidently an oversight, since Dr. Gray, whose
elaboration of the genus is adopted in full, restricts it to the species with
opposite and palmately-cleft leaves.

lobes ovate-lanceolate acute, as long as the similar but mostly broader and
overlapping denticulate lobes, and as the shallow-campanulate tube of the
corolla; filaments about as long as the oval anthers; fringed scales mostly
shorter than the tube, sometimes incomplete; styles equalling or shorter
than the somewhat pointed ovary ; capsule surrounded (not covered) by the
withering corolla, mostly 1-seeded.

Saline or brackish marshes in the Gila Valley on Sueda, Rothrock
(333), 1874; also on the California coast, near Santa Barbara, on Frankenia
and Salsola, Rothrock (101), 1875. Similar to C. Californica, from which
it is at once distinguished by its larger flowers and the presence of the
infra-stamineal scales.

Cuscuta (CLISTOGRAMMICA) ARVENSIS, Beyrich.—Ash Creek, on Soli-
dago, Rothrock (311),1874, and Camp Lowell, on Datura meteloides, Rothrock

juicy nurse-plant, have coarser stems than the Southeastern form and larger
flowers and fruit; the calyx is not angular, its lobes rounded; those of
the corolla very acute.

umbellate, erect; short filaments more or less hairy; fruit reflexed; style
hairy, especially at base, and geniculate toward the capitate stigma; flowers

toothed, thickish; calyx with forked hairs. Corolla light yellow; stamens
sub-included; style clavate; stigma sub-capitate—McArthy’s Ranch, New
Mexico (111). Notwithstanding the difference in leaves usually manifested
by these two species, there is a decided tendency for them to vary toward
each other; this along with the similar pubescence, the close resem-
blance of the flowers, and the same prominently ridged and roughened
campylotropous seeds, make me feel almost sure they will have to come
together.

Puysais Losata, Torr.—Low, spreading; root perennial; leaves oval

veiny beneath, and the marginal wings of the fruit developed into strong,
uncinate, glandular teeth, much larger than the central ones, which they.

I am indebted to Mr. Watson for the following statement :

“It is the same as 1751 Wright, 946 and 1013 Thurber, 191 Wislize-
nus; also collected by Coulter and Berlandier. It is G. globosa, var.
albiflora, Moq. in Bot. Mex. Bound. It is (without critical comparison),
however, very much nearer G. decumbens, but has acuter bracts.”

I am led to regard it as distinct from globosa, var. albiflora (which is
“ G. eriopoda, Gillies in Herb. Hook”), and certainly it is not G. decumbens, as
in the latter only the interior sepals are silky, and the outer ones are
obtuse, whereas in my specimens all are silky and acute.

EUPHORBIACE.
By Dr. GEORGE ENGELMANN.

CroTon coRYMBULOsUS.—Many erect stems from a ligneous base, a
span to a foot high, simple below, branching upward; stipules subulate,
deciduous; petioles about half as long as the oval or oblong, mostly acutish,
leaves, which are #—1}’ long, the lowest ones broader and shorter and often
acutish at base, all triplinerved at base, penninerved upward, whitish below,
greenish-gray above; stellate hairs slightly united to scales above, almost
free and loose below; inflorescence short, loose-flowered, corymb-like, 6-8”
wide, mostly moncecious; pedicels 2-3’’ long, much longer than the
flowers; male flowers with 5 spatulate or lanceolate bearded petals alter-
nating with the 5 lobes of the disk; 6-13 stamens with bearded filaments;
female flowers mostly apetalous; styles bifid to below the middle or usually
to the base, and together with the ovary and the oblong (3” long) capsule
stellate scaly; seeds linear-oblong, 2” long, delicately punctate-reticulate-—
Camp Bowie, New Mexico, Rothrock, 1474 (506). Through Western
Texas (Wright, 641, 1805) into Mexico (Saltillo and Buena Vista, Gregg, 71,
288). This species was first described by Torrey in Bot. Mex. Boundary,
p- 194, under the name of C. Lindheimerianus, in which Miiller, DC. Prod.
15, 2, 579, followed him. But Scheele’s plant thus named and described in

CATALOGUE. 243

Linnea, 25, 580, is an annual, mistaken by him for a shrub, which was
collected by Lindheimer near New Braunfels, Tex., in 1846, and distributed
in his sets under No. 526, and lately rediscovered along a railroad in the
Indian Territory by G. D. Butler. This plant was by Miiller taken for
Nuttall’s C. ellipticus, from Saint Louis, which is, however, identical with C.
monanthogynus, Michx., and in Gray’s Manual, ed. 5, 438, the same species
was again described as C. eutrigynus.

Croton Trxensis, Miill. 7. c. 692.—An annual, erect, dicecious plant of
the southwestern plains, Texas and New Mexico, 1-3° high, canescent or
greenish-gray (when it is C. virens, Mill. 1. ¢. 690), with linear-oblong leaves
24’ long on petioles 4-4’ long, without any glands; stellate hair free, not
scaly; flowers apetalous; stamens usually 10-13; filaments hairy; styles
twice or thrice 2-cleft at base, and, like the capsules, stellate-canescent; seeds
orbicular-ovate, somewhat compressed, with a small deciduous caruncula
below the apex—Santa Fé, N. Mex., Rothrock, 1874 (37), originally
described by Nuttall as C. muricatus, a name already preoccupied. Hen-
decandra Texensis, Klotzsch, and H. multiflora, Torr., are other synonyms
for this plant. Nuttall’s name refers to the curious knobs or almost spines
on the capsule, which are covered with prominent tufts of stellate hairs.
The styles are twice or often three times cleft, so that there are 12 to 24
stigmas.

Acatyena LinpuemMert, Miill. /. c. 875.—Many weak, ascending, downy
stems from a thick ligneous root, a span to a foot high, branching from the
base: leaves lanceolate-ovate, acute at both ends, serrate upward, hairy,
on short petioles, lower ones broader and shorter; slender, dense-flowered,
terminal spikes 2-3’ long, staminate upward; shorter spikes from the upper-
most leaf-axils; bracts oval, deeply dentate; styles divided into many very
slender, long-protruding, red branches.—Ash Creek, Arizona, Rothrock,
1874 (299), and through New Mexico to Western Texas.—Very near the
Mexican A. phleoides, Cav., with which Torrey, Bot. Mex. Bound. 199, was
inclined to unite it. The slender spikes with the delicate bright red fringes
give the plant a very elegant appearance.

glabrous, with the nerves of the upper surface puberulent, cordate, with an
acute sinus, broader than long, divided about # or more into 7 ovate or
ovate-lanceolate, incisely dentate, aristate lobes; stipules (2-3” long) seta-
ceously divided; petioles about 5—} the length of the leaf; cymes densely
many-flowered, short-peduncled, somewhat puberulent, with subulate-seta-
ceous, entire, or the lower ones setaceously ciliate, bracts; sterile flowers
4’ long, with lanceolate, aristate, usually entire calyx-lobes, half as long as
the spatulate petals; 5 (or rarely 6) exterior and 3 longer interior stamens,
all united to about half their length, bearing equal, linear-oblong anthers;
calyx-lobes of fertile flowers broader, larger, spinulose-dentate; styles 3, each
with 2 oblong stigmas; capsule obtusely triangular, oblong, 4’ or more long;
seeds linear-oblong (4—5’ long), with a large hoodlike, cut-fringed caruncle.—
Sulphur Springs, Arizona, Rothrock, 1874 (546), and to Southern New
Mexico and Chihuahua, Wislizenus. Leaves in the smallest specimens
(Wislizenus, Chihuahua) 2’ long by 24’ wide, in Rothrock’s largest 6’ by
8’, always with 7 lobes and usually with 2 smaller additional ones at
base. Evidently a form of the Mexican J. macrorhiza, and with the same
curious caruncle of the seed, distinguished by the longer petioles, the much
more deeply divided leaves, with more numerous and more deeply cut-
toothed lobes, and an acute (not wide or truncate) sinus Torrey’s, J. mul-
tifida, Bot. Mex. Bound. p. 198 (not Linn.), is evidently the same thing, as
already suggested by the author himself, and probably nearer Bentham’s
type than our plant, as the leaves are said to be only 3-5-lobed.

R. R. Report, 2, 174; Bot. Mex. Bound. 186; Boissier in DC. Prod. 15, 2,
30.—A_ prostrate, much branched, glabrous, glaucous perennial, with
orbiculate-cordate, entire, rather fleshy leaves (2-3’’ wide) and conspicuous,
triangular, membranaceous, whitish stipules; involucres axillary, solitary,
or sometimes crowded into foliaceous cymules, broadly campanulate with
conspicuous, white, transverse, entire or undulate appendages of the glands ;
capsules triangular; seeds reddish-gray, linear or oblong, smooth or some-
times very slightly undulate—dZuni, Rothrock (173 in part), 1874, to Fort
Tejon, California (274), 1875, and generally from Western Texas to South-
ern California and into adjoining Mexico. A very distinct species, easily

recognized by its glaucous color and whitish stipules and white append-
ages. In Arizona it is called “ Rattlesnake-weed ”, as its acrid juice is con-
sidered an antidote against the venom of that reptile. In Mexico, to this,
as well as to other allied species, known under the name of Golondrina,
great medicinal virtues are ascribed.

or ascending branches a span to a foot long; linear or oblong-linear entire
leaves, acutish at both ends, 4-6” long, 1’ wide; conspicuous triangular
incised stipules and alternate loose-flowered leafy corymbs; involucres
broadly campanulate, with 2-4 large, concave, narrow-margined or inap-
pendiculate glands; broad triangular capsule; smooth gray seeds thick
and short, triangular, acute—Camp Goodwin, Gila Valley, Arizona, Roth-
rock (339), 1874. Apparently a common plant in the sandy valleys of the
Rio Grande (Wright, Brandegee) and Gila, but very rarely collected. Dr.
Rothrock’s specimens have a ligneous, very stout, tapering root 3’’ in diam-
eter, with many stems (1-14” thick) from the neck, just as we sometimes see
other annual Anisophylla, H. hypericifolia among them, so that they simulate
and actually become perennials; real perennials, however, such as the
next species, have cylindric or tuberous roots, usually with slender and
even filiform bases to the stems, which are buried beneath the surface.
The slender leaves and the short, leafy, alternate flowering branchlets, much
shorter than the internodes of the elongated stems, characterize this species
at once. Like the Californian . ocellata, it is distinguished by large cup-
shaped glands, usually less than four in number, and scarcely or not at
all margined.

gular-oblong, undulate and scrobiculate—Santa Fé, Rothrock (13), 1874;
number 1003 is the same from Arizona. Not rare from Western Texas,
through New Mexico and Southern Colorado to Arizona. A diminutive,
suberect bush of many stems and branches, very variable in the width of
its leaves, but readily recognized by the characters enumerated.

Evupnorsia (ANISOPHYLLUM) PoLycaRPa, Benth. Bot. Sulph. 50; Bot.
Mex. Bound. 186; Boiss. /. c. 44——A perennial, often flowering in the first
year as an annual, prostrate or erectish, glabrous, sometimes pubescent
(or even tomentose in a variety), with orbicular-cordate or oblong entire
leaves, always with linear, delicately ciliate stipules; involucres axillary,
rarely crowded into few-flowered cymes; appendages of the dark red (or,
when dry, black) glands large and conspicuous, or smaller; seeds gray-
reddish, linear-oblong, quadrangular, smooth or slightly undulate. The
typical, large-flowered, glabrous form is found principally along the Pacific
coast from Cape St. Lucas to the southern part of the State of California ;
inland, and especially in the California Desert and up the Gila, where Dr.
Rothrock collected it in 1874, a larger, wide-spreading, very much ramified
form is found, with smaller, glabrous or pubescent, oblong or oblong-linear
leaves 4-14” long, with smaller involucres, very small, almost or entirely
inappendiculate glands, and very short styles, but seeds of the same size
and form as in the type. The stipules of all forms are alike, linear, entire,
minutely ciliate. ££. micromera, Boiss. 1. c. 44, seems identical with this
last form, and we will have to consider FE. melanadenia, Torr. Pacif. R. R.
Rep. 4, 135, as a tomentose variety, as suggested by S. Watson; an inter-
mediate form is 2. cinerascens, Engelm. Bot. Mex. Bound. 186.

but readily recognized by its glabrous, obovate leaves, acute at the unequal
base, broader and serrulate at the rounded tip; stipules setaceously divided ;
involucres in lateral leafy clusters; seeds gray, linear, acutely 4-angled,

slightly wrinkled or pitted. The closely allied 2. glyptosperma, Engelm.,

may always be distinguished by the broad semicordate base of the leaves,
the lower half of which is protracted and almost auriculate, and by the
sharply cross-ribbed and at the angles, notched seeds. The form collected
at Zuni is suberect, nearly a span high, with leaves more sharply serrate
than usual, and more distinctly rugose.

EKurHorBiA (ANISOPHYLLUM) PEDICULIFERA, Engelm. Bot. Mex. Bound.
186; Boiss. l. c. 48.—Plant, pale dull green, covered with a short, scanty
pubescence ; many prostrate stems from a perennial root, a span to a foot
long; leaves rather large (6” long or more), oblique, oblong, obtuse,
entire; small stipules triangular-subulate; involucres in few-flowered,
lateral, leafy cymes; glands with broad, dentate appendages; capsules
canescent ; seeds oblong, angular, strongly marked with 4 deep transverse
grooves, deeply notched on the edges.—Cienega, near Tucson, Ariz.,
Rothrock, 1874 (576). A native of our extreme Southwest, from Arizona
to Southern California and into adjoining Mexico; well marked by its
larger, dull grayish-green leaves, and especially by the (for the section)
large, deeply grooved and notched seeds, which curiously simulate some
insect.

Kurnorsia (ANISOPHYLLUM) HYPERICIFOLIA, Linn.; Bot. Mex. Bound.
188; Gray, Man. 432.—T wo forms were collected by Dr. Rothrock in 1874.
The common form (672) from Camp Crittenden, Southern Arizona, is that of
the States, called E. Preslii, Guss., Boiss. l. c. 22, glabrous, with rather small,
blackish, much cross-wrinkled seeds The other form (720), from Camp
Lowell, Southern Arizona, has seeds larger than the last, in size between
those of HL. Brasiliensis, Lam., and the large-seeded EH. Bahiensis, Boiss.,
and in form similar to them; all of these have thick, short, almost ovate-
cubic, black seeds, with few prominent tubercles arranged in about 2 inter-
rupted transverse ridges. Our plant is nearly glabrous; leaves very pale
below, with long, sparse ciliz on the upper edge near the base—The
different species allied to E. hypericifolia require further study, as it is a
mooted question whether the pubescence of the plant and even that of the
capsules, and the size, the color, and the markings of the seed, constitute
here specific differences. If they do not, then we have here one of the
most polymorphous species, spread over all the warmer countries of the

A rare plant, found only once before, by Wright, mistaken by me for
a form of E. dentata, but well distinguished from that species (which extends
far into Mexico) by its involucres and seeds. EH. dentata has much smaller
turbinate involucres, with broad glands, and smaller ovate or subglobose,
minutely tuberculated seeds.

triangular, obtuse, almost flat scales, and covering about 4 of the oblong,
long-pointed nut.—Rocky Canon, Arizona, Rothrock, 1874 (287). Extends
through Arizona and New Mexico to Western Texas. Botanically a most
interesting species, as it combines many characters of the White Oaks, viz.,
the annual maturation and especially the position of the abortive ovules at
the base of the nut, with characters of the Black Oaks, viz., the black bark
and coarse wood, the small number and large size of the stamens, the
long, recurved styles, and the tomentose inner coating of the shell; the
leaves show, as they do in many Black Oaks, a stronger reticulation on
the upper than on the lower side.

mon Eastern type. The first may be characterized as var. macrophyllum,
with large orbicular-obovate, glabrate leaves, only in the young state with
an evanescent pubescence, 14-24’ long, 3- and often 5-nerved ; staminate
spikes unusually thick, with 4 or 5 short joints, each with 10-40, compara-
tively large, pubescent flowers—They grow on soft woods (Ash, Willow,
Poplar, Sycamore, and Sapindus) on the Gila and Bonita Rivers, and
extend into Southern California, G. K. Gilbert, Dr. Rothrock.

Var. vitLosum (Phor. villosum, Nutt.), with woolly, obovate, and var.
ORBICULATUM, with rounded, pubescent leaves, are found on hard woods,
principally on Oaks, in Oregon, California, Arizona, and southeastward.
On the mountains about Camp Apache, Arizona, they grow on different
varieties of Quercus undulata.

PHoraDENDRON Ca.irornicum, Nutt. Pl. Gambel. p. 185.—Slender,
terete, much branched, leafless stems, 1-2° long, bearing, in the axils of

1- or few-jointed spikes, each joint with 2-6 flowers; staminate flowers
with oblong anthers, the cells opening longitudinally.—Arizona and South-
ern California, G. K. Gilbert, Dr. Rothrock, on Mimosee, Larrea, and a
few other shrubs.

PHORADENDRON JUNIPERINUM, Engelm. Pl. Fendl. p. 58.—Half a foot

two we find no other secondary formation on the fertile plants, but in the
other species sterile branchlets are developed on them which would flower
in the following year; thus these latter continue their existence for a longer
time than the two first ones.

greenish-yellow, dichotomously branched; branches suberect, single or
with accessory ones behind the first; flowers in short, usually 5-flowered,
spikes, staminate ones less than 1’ wide, with orbicular-ovate acutish lobes ;
fruit 24’ long —On Pseudotsuga Douglasii from New Mexico (on Santa Fé
River, Rothrock, No. 69, 1874) to Utah, Parry, Siler, and Northern Ari-
zona, Camp Apache, G. K. Gilbert (109), 1873—Flowers May—June.—
Similar to the last, but smaller, and never with verticillate branchlets or
flowers, which are so common in that species The thallus-like tissue or
stroma, which creeps along within the bark of the nurse plant, buds out in
autumn all along the three years old shoot; after about 12 months, the
flower-buds are formed, to open in the following spring, after which the life of
the male plant is exhausted; but it takes another year to perfect the fruit.
The female parasite, now fully three years old, generally dies, but sometimes
lives and fructifies another season. The Northeastern A. pusillum, Peck,
behaves in the same manner, while in A. Americanum and some other
species the buds of the parasite make their appearance at first only among
the older bud-scales of the pine branch.

Var. ? MICROCARPUM is parasitic on Picea Engelmanni, found by- Mr.
Gilbert in 1873 (100 and 102) in the Sierra Blanca, Arizona; it is a little
taller, 1-2’ high, but has much smaller fruit, only 13? long, the smallest
of any American species.

recurved ; staminate flowers few and scattered, or in 3—7-flowered spikes,
1” in diameter, with ovate, acute lobes ; inflorescence often bearing: sterile
branches from the same axils as the fruiting ones and behind them; fruit
13-13” long.

On Nut-pines (P. edulis and monophyllos) from Southern Colorado
through New Mexico to Arizona, G. K. Gilbert, 1873 (116), Dr. J. B.
Girard, 1874. Flowers August and September. Intermediate in size and
color between the last and the following; well marked by its divaricate
habit and its scanty flowers.

ARCEUTHOBIUM ROBUSTUM, Engelm. Pl. Fendl. p. 59; A. eryptopodum,
Engelm. Pl. Lindh. p. 214.—Stout, 2-4’ high, 2-3” thick at base, panicu-
late, much branched, brownish-yellow to dark olive-brown; staminate plants
smaller than the pistillate ones; staminate spikes with much-compressed,
adpressed buds; flowers mostly 3-parted, 14-14” wide; anthers attached
above the middle of the ovate, acute lobes; ripe fruit 24” long.

Only on Pinus ponderosa, Colorado, New Mexico, and Arizona; Camp
Apache (G. K. Gilbert, 1873) and Mount Graham (Rothrock, 787); 1874.
Flowers in June. Fruit mature in August and September. The closely
allied A. occidentale, Engelm., is distinguished by more elongated spikes,
ventricose, divaricate buds of the staminate, mostly 4-parted, larger flowers,
with lanceolate, acuminate lobes and anthers attached below their centre ;
it also occurs on Pinus ponderosa, but more frequently on other Conifers.
Both persist for several years, the female plants always longer than the male.

bases, two-ranked, sessile, persistent leaves, which eventually leave on the branches circular, flat scars;
flowering from the axils of the leaves of the previous year; staminate flowers (usually called staminate
aments) in the form of an oval or cylindrical ament ; anthers without crests, bursting transversely with
large (0.11-0.14™™ in the larger diameter) 2-lobed pollen-grains; cones erect on the more or less hori-

broad, transversely dilated scale; wings of seeds pale, very oblique, as long
as wide; cotyledons 5-7, usually 6.

Common on the mountains of New Mexico and Arizona. Thence
extending through Southern Colorado and Utah and throughout the Cali-
fornia Sierras. A tree of beautiful foliage, highly prized in cultivation ;
furnishing better timber than the last, from which (besides the characters
already enumerated) it can always readily be distinguished by the two
resin-ducts of its leaves lying close to the epidermis of the under surface.
In Colorado as well as in California it has often been named A. grandis, a
species which properly belongs to the coast regions of Oregon, the Lower
Columbia River, Vancouver Island, ete.

Picka* EnGetmanni, Engelm.; Abies Engelmanni, Parry; Pinus com-
mutata, Parlat—Large trees, 60-100° high, with thin, cinnamon-brown,
scaly bark; branchlets mostly pubescent; leaves 4-sided, slender and
acute or acuminate in younger, and shorter, stouter, short-pointed, and
curved in older trees (especially in higher altitudes), with stomata on
both sides; cones oval or oblong, about 2’ long, paler or purplish, fall-
ing off at maturity; scales thin, erose-denticulate, broad, with a rounded
edge or usually somewhat prolonged upward and truncate; seeds half as
long as the very oblique wing, usually with 6 cotyledons.

San Francisco Mountains, Bischoff; Sierra Blanca, Gilbert; Mount
Graham, Rothrock (784). The most southern localities known of this
northern and sub-alphine species, which extends through the Rocky Mount-
ains to British Columbia and to Oregon, forming extensive forests. A
beautiful tree, often 2° and even 3° in diameter; timber similar to that of P.
nigra of the Northeast and P. excelsa of Europe: above timber-line, it
dwarfs down to mere shrubs, often prostrate, but loaded with cones.

*Picea, Link, not Don; Abies, Don; Abies sect. (Sprnces), Gray’s Man.; Pinus sect. Picea,
Endl., Parlat.—Coniferous trees with single evergreen, more or less 4-sided leaves, which at last sepa-
rate from a prominent, persistent, ligneous base; flowering from the axils of the leaves of the previous
year ; staminate flowers as in Abies, but stamens tipped with a large, nearly orbicular, denticulate crest;
cells opening longitudinally ; pollen as in Abies, 0.09-0.13"™ in longer diameter; cones pendulous from
the ends of short or elongated branchlets, maturing in one season ; scales and small enclosed membra-
naceous bracts persistent on the axis ; seeds without l.alsam-vesicles, imbedded in the excavation of the
membranaceous base of the wing, which leaves tneir under side nearly free and permits them to drop
out.—Trees of slower growth than the firs, with white, soft, but tough, close, and highly esteemed timber.

Psrupotsuca* Dovuauasu, Carritre; Abies Douglasii, Lind]l.—Often
one of the tallest trees known (in favorable localities, in Oregon, even
390-350 feet high), with very thick, much cracked, brown bark, spread-
ing branches, conspicuous, somewhat persistent bud-scales, slender, flat,
linear, obtuse or acutish leaves, ?-14, rarely 14 inches long; cones ovate-
oblong, usually 2-3’ long, brown, well marked by the protruding, long-
cuspidate bracts; scales orbicular, concave; oval wings about as long as
the somewhat triangular, pale seeds; cotyledons 6-8.

Common through Arizona, as it is through all the western mountain
regions, down into Mexico.—Leaves stomatose and whitish only on
the lower surface, with 2 resin-ducts close to the epidermis of the under
side.

Pinust FLEXILIS, James; Parlat. in DC. Prod. 16, 2, 403.—A middle-
sized tree, with a smoothish, or, in old trees, lightly furrowed, pale or ash-gray
bark; leaves in fives, mostly entire and smooth-edged, 14-2’ long, ina loose,
deciduous sheath, about 4’ in length; involucre of the oval staminate flowers
composed of 8—9 oval, obtuse scales; anthers with a short lacerate or toothed
crest; cones sub-terminal,t{ spreading, or slightly reflexed, ovate-cylindrical,

* P3EUDOTSUGA, Carr. Conif. ed. 2, 256; Abies, sect. Tsuga (in part), End].—Coniferous trees, with
flattened, entire, somewhat 2-ranked, distinctly petioled leaves, leaving on the branchlets scarcely
prominent, transversely oval scars; flowering from the axils of the leaves of the previous year; staminate
flowers resembling an oval or subcylindrical ament; anthers with a recurved, spurlike point; cells
cpening longitudinally; pollen oval-subglobose; sessile cones subpendulous, maturing in one season ;
scales and their much elongated bracts persistent on their axis; seeds without balsam-vesicles, not
separating from the wing.—Very large trees, with very thick bark and reddish or yellowish wood, of
secondary value, which is characterized and well distinguished from the wood of all the allied genera,
and of most coniferous woods, by the abundance of spiral vessels, otherwise so rare in this family. The
difference in the pollen, the seeds, and the leaf structure make a separation of this genus from Abies as
Well as from Tsuga necessary.

t To the character of the genus Pinus may be added: Staminate flowers surrounded by an involu-
crum, of a somewhat definite number of scales (3-15 or 20), the lowest, lateral, pair of which are strongly
keeled; pollen-grains lobed, similar to that of Abies and Picea, but only half as large, 0.04-0.06™™ wide.
The bracts of the cones, which, in the allied genera, remain membranaceons, become here much thickened
aud corky, and, together with the scale below them, form a sort of cell for the reception of the seeds. The
base of the wing only partially covers tbe upper side of the seed, and usually forms a mere rim around the
seed, which easily separates from it; in a few species, the wing is firmly attached to the seed, and ina
few others it is reduced to a narrow margin; the seed never shows balsam-vesicles.

t The fertile aments of Pinus, and consequently the cones, are usually called terminal, but they
never are that, but always lateral, and either appear between the uppermost leaves and the terminal
lnd, when they may be called sub-terminal (P. resinosa, Strobus, sylvestris), or the axis continues to
clongate after the formation of the aments, when these and consequevtly the cones become lateral, the
axis bearing leaves and sometimes other awents above them (/’. Tada, and especially inops, and in
Lurope, P. Halepensis). In some species both forms occur, or only a few leaf-bundles intervene between

3-44’ long, squarrose by the more or less protruding thin-edged scales, the
free part of which is rounded or more or less triangular, rarely reflexed;
seeds 5 or 6” long, somewhat angled, with a narrow deciduous wing-rim;
cotyledons 6-7.

Var. a, SERRULATA.—Leaves slender, slightly and distantly serrulate, and
as in the two following varieties, with few or scarcely any stomata on the
back; cones of the ordinary form.

Var. £. Macrocarpa.—Leaves slender, entire; cones cylindric, 6-8’
long, 24’ in diameter, the apophysis of the scales short, rounded.

Var. y. REFLEXA.—Leaves as in last; cones ovate-cylindrical, about 4’
long; apophysis elongated, reflexed.

A middle-sized tree, rarely more than 50 feet high, on the higher
mountains of Colorado, New Mexico, and Arizona, extending to Southern
California. Var. @ was found by Dr. Rothrock on Mount Graham (783) ;
var. y, by the same, on Santa Rita Mountain (east of Tucson) and in the
Sanoita Valley (654 and 1001). The cone of 1001 resembles that of the
Asiatic P. Koraiensis, or of a small P. Ayacahuite from Mexico. Var. £ was
collected on the San Francisco Mountains by Mr. Ferdinand Bischoff in
1871.—The species is intermediate between the true Strobi and Cembra; of
the former it has the peripheral resin-ducts, usually 2, on the dorsal side;
with the latter it has the large, almost wingless seeds in common; from
both it is distinguished by the back of the leaf being marked by a single,
or a few series of stomata. It thus becomes the type of a third section of
the Strobus-like Pines, which may be arranged as follows:

1. Cembra, with large, almost wingless seeds; dorsal face of leaves with-
out stomata; resin-ducts of the serrulate leaves imbedded in the parenchyma;
P.Cembra of Europe and Asia with appressed, and P. Koraiensis of Northeast-
ern Asia with squarrose cone-scales. 2. F’lexiles, with similar seeds, but entire
or nearly entire leaves, with a few series of stomata on back, with peripheral
ducts; P. flexilis, P. albicaulis, and the Asiatic P. pygmea. This last is thus
entirely distinct from P. Cembra, as a variety of which it has long been
considered by Parlatore and other botanists, while P. Mandschurica, at least

the aments and the terminal bud. When, iu the fullowing season, the axis elongates, while the ameut
matures to a cone, this latter naturally bccomes quite lateral, but we continue to designate it as sub-
terminal, in relation to its own, coétaneous, part of the axis.

what I have seen under that name, is a true Cembra, not to be thrown
together with P. pygmea, as has been done, and distinguished from Cembra
itself by the denticulate Strobus-like leaf-tips. 3. Hustrobi, with distinctly
winged seeds, leaves sharply serrulate on the edges and generally denticu-
late all over the tip, mostly without stomata on the back, and with periph-
eral ducts, like the last. Of this subsection we have P. Strobus, monticola,
and Lambertiana; Mexico has P. Ayacahuite; Japan, P. parviflora; the East
Indies and Turkey, P. excelsa with P. Peuce.

Pinus MonopHy.1os, Torr. & Frem. Report Expl. Exped. 1842-1844,
p- 319, t. 4; Parlat. 1. c. 378—A small tree, of scraggy growth, with gray
bark and stout, mostly single,* terete leaves (rarely in pairs, and then
semicylindrical and entire on the margins), 14-2’ long, 3-1’ thick or wide,
with a deciduous sheath; involucre of the staminate flowers of about 6
scales; anthers with a short, entire or denticulate knob; cones subterminal,
ovate-subglobose, 2 or 24’ long and nearly as thick, consisting of few large
scales with thick pyramidal apophyses, but without prickles; oval seeds
about 4’ long, with a wing nearly 1” wide; cotyledons 7-10.

The oft-described Nut-pine of Fremont’s first expeditions, 35 years
ago, common from Arizona to Utah and California. This and the follow-
ing species furnish an important article of food to the Indians and other
natives. That single leaf, before its nature was properly understood, troubled
botanists a good deal, so that Endlicher, supposing that the single leaf con-
sisted of two agglutinated ones, went so far as to change the name into P.
I’vemontii. They are really single leaves, and the only instance of such
leaves in the genus (I do not speak of the primary leaves of seedlings or
young shoots, but only of the secondary leaves, which grow in bundles on
what we must take for reduced branchlets).

* The fresh leaves of pines, when single, are terete, and when dry, become grooved and ridged; the
leaves which grow in pairs are semiterete, flat on the upper or inner, and convex on the lower or outer
side, and only when (on the tree as well as still more in the herbarium) they become dry, they assume that
chann: I]ed form which we tind so often described as characteristic of a species; those leaves that grow
in bundles of 3 or 5 are convex on the dorsal and ridged on the upper side; those with 3 are flattish,
about half as thick as wide; those with 5 are triangular and nearly as thick as wide. It is therefore
superfluous to minutely describe the form of the leaves, as that is already given when the number
within the sheath is stated, nor is it proper to describe the dried and shrivelled condition. The serra-
tures, their closeness, the size of the minute teeth or their absence (only in a few Western American
species the edges of the leaves are without teeth) are of much greater importance, and to some extent
the nature of the tip is also of value.

Pinus EpuLis, Engelm. in Wisliz. Mem. note 2.—Similar to the last,
but with more slender, entire leaves, mostly in pairs, rarely in threes; stann-
nate flowers surrounded by a 4-leaved involucre ; anthers with a knob or
short spur; cones and seeds similar to those of the last species, only a little
smaller; cones usually but 14’ long; cotyledons as in previous species.

Camp Bowie, Arizona, Rothrock (493). Common from Southern
Colorado through New Mexico to Arizona. The two species here described,
together with the slender and 3-leaved P. cembroides, with harder shells to
the larger seeds, and 8-12 cotyledons, and the little-known 4—5-leaved
P. Parryana of the northern part of Lower California, constitute a small
group of very peculiar Pines, which we may designate as the Cembroid
Pines, characterized by the leaves of the flexilis group (with entire margins,
peripheral ducts, and deciduous sheaths), by the seeds of Cembra and hy
the cones and scales of Pimaster. Perhaps it would be proper not to lay
too much stress on the number of leaves and minor characters, nor on
their geographical difference, and to unite them under the oldest and most
appropriate name of P. cembroides, Zucc., though systematists, counting
the leaves, have separated them widely in their books.

There is no pine entirely analogous to them in the Old World, unless
we should refer here the little-known P. Bungeana, Zuce.; Murr. Conif.
Jap. 18, of Northern China. It has similar, small, subglobose cones,
though with less prominent knobs, but armed with recurved prickles; the
seeds are smaller, with a very distinct wing, the leaves in threes lose their
sheaths as our Nut-pines do, but are serrulate, and have several peripheral
ducts, but, singularly enough, also usually a single interior or paren-
chymatous one, forming thus a link between several groups.

Pinus Arizonica, n. sp.—A middle-sized tree, 40° high, 2-3° in diam-
eter; branches squarrose, with persistent bracts; leaves in fives, 5-7’
long, 4’’ wide, closely serrulate, in a sheath over 1’ long (when old less
than half as long); oval cone 2#’ long, 14’ thick; scales with a prominent
knob, which in the lower ones is recurved, armed with a recurved prickle.

so difficult as Pinus, but I find it impossible to unite it with any other of
the allied species. It has the cone of P. ponderosa, especially of that form
figured by Torrey as P. deflexa, and, like all forms of that species, it has
the peculiarity that the fallen cones, found on the ground, are always
imperfect, their lowest part remaining attached to the branch for another
season; I do not know of any other pine with this singular character.
But we could not well class this 5-leaved pine with the 3-leaved ponderosa.
On the other hand, the form of the cone and its scales will not permit us to
refer it to the Mexican P. Montezuma, though the structure of the leaf is
very similar to that of this polymorphous species, which appears to include
even P. Hartwegii. The three parenchymatous ducts of the leaf and the
strengthening cells* within the sheath of the vessels are exactly as we find
them in Montezuma, and different from ponderosa.

Pinus ponperosa, Dougl. Parlat. J. c. 305.—A large tree, with large and
spreading head, thick, deeply cracked, red-brown bark, and heavy, resinous,
yellowish wood; thick branchlets, rough from leaf-scars and the persistent
remnants of bracts; leaves in twos or mostly in threes, 4—8’, in some rare
forms 10-12’, long, #” wide, with sheaths at first 1’ long, when old with-
ering to 2 or 8” long; staminate flowers cylindric, with an involucre of 10
or 12 scales, the lowest pair of which is about two-thirds as long as the
innermost; anthers with a large sub-orbicular crest; fertile aments sub-
terminal; patulous cones oval or rarely elongated, very variable in size,
2-6’ long; knob of the scales more or less prominent, and in some forms
even recurved, bearing a rather stout prickle; seeds black, ridged on the
lower side, wing broadest in the middle; cotyledons 6-8, or in the largest
seeds as many as 10.

Rocky Mountains and adjacent regions to Oregon and California, mostly in
the middle altitudes; the most common and most useful timber of many

*This name has been given to longitudinal cells with very thick walls, destitute of chloropby!},
which are characteristic of most pine-leaves, and by their different disposition aid in distinguishing thei
from one another. They are generally arranged close to the epidermis, and especially in the angles of
the leaves, and have usually about the same diameter as the epidermis-cells themselves. We find them
also occasionally surrounding the ducts, e. g. in P. ponderosa, also in the Cembroid Pines and in P. Lal-
fouriana and P. aristata; while in P. flexilis they always leave the ducts free, a character by which
we can readily distinguish the leaves of these species, otherwise so similar. Not rarely are they found
within the sheath, strengthening, as it seems, the ceutre of the leaf.

parts of that district and generally known there as ‘‘yellow pine”. A most
variable tree, several forms of which have received distinct specific appel-
lations, but the specimens collected in these expeditions all appear to
belong to the ordinary smaller-leaved and smaller-fruited form. Whenever
the macroscopic characters leave any doubt, the microscopic structure of
the leaf appears to offer a sure guide. The leaves contain two or three or
often more parenchymatous resin-ducts, usually of uncommonly small diame-
ter, always with some, and often surrounded by many, of those strengthening
cells of which I have spoken before; the same cells occur within the sheath,
above and below the bundles of vessels. I have examined the leaves of
20-30 specimens from the whole range of the species, and have never failed
to discover this same structure, which I must therefore consider as char-
acteristic of the species.

Pinus Camuanuana, Engelm. in Wislizen. Mem. note 26; Parlat. J. c.
397.—A middle-sized tree, with ternate, closely serrulate leaves 25-4’
long; the loose glistening sheaths 4’ long, deciduous after the first season;
staminate flowers slender, cylindric, about 4’ long, sometimes interspersed
among the foliage; involucre as long as the nearly entire-margined bract,
of 8-10 scales, the outer about half as long as the inner ones; anthers with
an almost orbicular crest; oval cones sub-terminal, small, 14’ long; knobs
of the scales bearing recurved, deciduous prickles.

Southern Arizona, in Sanoita Valley, at 6,500 feet altitude, Rothrock

by the characters given, and especially by its deciduous sheaths. All the
Strobi and Cembroids have such deciduous sheaths, but among the Pinas-
ters the sheaths are persistent, except in one or two Mexican species, in P.

Southern Colorado to California, apparently not noticed in Arizona.
A valuable timber tree of the northern mountain regions, forming large
forests in the higher altitudes of the Rocky and California mountains,
reaching into the British Possessions. The original form, discovered by
Douglas near the mouth of the Columbia River (P. Bolanderi, Parlat.), is a
seaside tree, extending up and down the coast, resisting the ocean storms,
as does P. Halepensis those of the Mediterranean, and protecting the inside
vegetation; it is distinguished by its low, scrubby, and often shrubby
growth (whence probably the name), and its slender leaves, not more than
3-3” wide; northward, in British Columbia and Alaska, both forms com-
pletely run together. The species was formerly confounded with the East-
ern P. inops, which differs by its lateral, more or less pedunculated cones ;
it is more closely allied with the Northern P. Banksiana, which, however,
bears its scarcely prickly or entirely unarmed, mostly lateral, rarely sub-
terminal, cones erect or patulous, never recurved: a very unusual occurrence
among pines. The cones of the Rocky Mountain form, and also those of
the seaside scrub, are usually persistent for many years, and often remain
closed after maturity (serotinous), while in the variety of the Sierras they
appear to open on maturity, and to drop before the following season, as
Prof. C. 8. Sargent observed.

fissured bark; branchlets slender; leaves elongated, often resiniferous on
the back, with slightly denticulate margins; berries large, glaucous, many-
seeded.

An important tree in Western New Mexico (Fort Wingate, Rothrock,
number 140, in 1874) and Northern Arizona; readily distinguished from
all the other species by its bark, which Dr. Rothrock compares with that
of the white oak, and others with the bark of pine.

JUNIPERUS CaLirornica, Carr., var. Uranensis, Engelm. Junip. 588.—
More slender than the western type, J. Californica, with thinner branches
and smaller, not so strongly fringed leaves, often in twos; smaller, more
globose berries; embryo with 5 cotyledons, as in the species.

ENDOGENS.
ORCHIDEZ:.

Microstytis MontanaA.—Bulb 1’ in diameter; stem 6’-15’ high, with
2-3 broad sheaths at base; 1-2 oblong-lanceolate, obtuse leaves, tapering
below into sheaths; flowers many, sessile in a narrow spike (which is 2-5’
long), yellowish-white, without the ovary 1” long, each one subtended by
an oval bract 1” long; sepals equal or nearly so, oval, rather obtuse ; lip
next the axis, somewhat triangular-ovate, conspicuously sagittate at base,
but obtuse or occasionally notched at apex; lateral petals filiform (usually
coiled up), somewhat longer than the sepals; column very short, tapering to a
point, and with a very minute tooth on either side below ; stigma a small depres-

sion or pit; anther nearly sessile, of two parallel cells, open above, and free above
trom column, pollen masses two, not divided, or with a mere sulcation, attached to
the minute gland on the tip of the column ; mature capsules 3-4” long, oval.

It is particulary remarkable in having a dense spike of sessile flowers.
Mount Graham, Arizona, at an elevation of 9,500 feet (734). It appears
to be extremely rare. I am indebted to Mr. Watson for indicating the
genus, and also for the information that the plant was probably undescribed.

HABENARIA LEUCOSTACHYS, —?—Stem leafy ; leaves oblong-lanceolate,
obtuse ; spike long, densely flowered; bracts about as long as the flower.
My specimen from Willow Spring, Arizona (269), shows a well-marked,
hooded, posterior sepal, such as we might expect to find in HZ. dilatata, but
is without the dilated base to the lip and the trowel-shaped rostellum of the
latter species; lip lanceolate, not longer than the somewhat curved spur.
The locality whence this specimen was obtained was a very cold, damp one
(even though in Arizona), at an altitude of 7,195 feet.

HABENARIA HYPERBOREA, It. Br.—Colorado (965).

HABENARIA DILATATA, Gray.—Colorado; in company with the above.
Quite too near some forms of the above species, as the characters on which
the distinctions are founded vary immensely.

EPIpACcTIS GIGANTEA, Doug]l.— Nevada.

GoopyerA Menzresu, Lindl.—Entirely in accord with the figure (Spi-
ranthes decipiens, Hook.), 204, Hook. Fl. Bor. Amer., except that on either
side of the base of the lip, in some of my specimens, there is a distinctly
serrated crest. Other flowers from the same spike have a single crest
in the median line.

Mount Graham, Arizona, at 9,500 feet elevation (749).

SprranTHES Romanzoviana, Chamisso.—Mount Graham, Arizona, at
9,500 feet elevation (752); Utah; Colorado.

CoraLLorHiza Macrai, Gray ?—I name this specimen so with great
doubt. It will more likely prove to be new, I think. It differs from the
genuine C. Macrei in its smaller flowers, short, thick column, spur short,
thick, and truncate, the lip oval, and with a distinct auricle on either side
at base. |

unlikely that the summits of the White Mountains of Arizona still further
north would show even a greater number.

IRIDE AS.

Irts Totmeana, Herb. Bot. Beechey.—South Park, Colorado, com-
mon (967). Dr. Loew also collected an imperfect specimen from further
south, probably New Mexico.

SISYRINCHIUM MUCRONATUM, Michx. (S. Bermudiana, L., of Preliminary
teport, 1874).—Regarded by Mr. Watson as distinguished from S. Bermu-
diana, Li, “by its low and usually very slender habit, the scape always
terminated by a single spathe sessile within the terminal longer bract, and
the flowers small, with segments setosely mucronate and capsules globose”
(Proc. Amer. Acad. xii, p. 277). My specimen (945) from Colorado has
larger flowers, and is probably somewhat out of range; still I regard it as
belonging to this form.

SISYRINCHIUM BELLUM Watson (Proc. Amer. Acad. J. c.).—6-18' high;
leaves narrow, smooth, shorter than the smooth stems; terminal bracts
1-3’ long

g, not longer than the peduncle; spathes 2, enclosing 4-7 flowers

and maturing 2-4 capsules, which are somewhat obovate and transversely
wrinkled when mature; seeds obtusely angled and distinctly roughened,
about 10 to the cell, light purple; petals 4-6’ long, toothed or slightly
mucronate ; stamineal column nearly 3” long and pubescent at the base.
The stem is narrowly margined.—Zuni, New Mexico, 6,500 feet eleva-
tion (171).

Sisykincuium Arizonicum, Rothrock, Bot. Gazette, vol. 2, p. 125.—1-2
feet high; stem proper smooth, ancipital; leaves 6-12 inches long, 2-6
lines wide, gradually attenuate into an acute point, 2-4 distinct white ribs
in centre, and one or more less distinct toward either margin, minutely
pruinose-glandular, slightly roughened on the margin; spathe of two
lanceolate leaves regularly tapering to the top, somewhat shorter than the
peduncles, of which each branch bears from 2—5 (most frequently 2); flowers
yellow, 1-14’ in diameter, bright yellow segments of the perianth broadly
lanceolate ; anthers 6 lines long, linear, twice as long as the dilated fila-

down into linear divisions; seeds (immature) oval or nearly round, mar-
gined, on a funiculus longer than their diameter.—Piatn XXVI. Natural

This handsome species (238) I discovered at Willow Spring, Arizona,
at an altitude of 7,195 feet; grows in damp places. There are indications
of its presence elsewhere in Arizona, and allied species are found in Mexico.

AMARYLLIDE.

spreading, lanceolate, tapering from a broad base, concave, 6-12’ long, 1-2’
wide, not constricted above the base, very thick, hard, glaucous and rough,
terminating in a long (1 inch) pale spine, with broad whitish teeth on the
margin; flowering stalk 5-7° high, with a spike-like raceme of yellow
flowers each 1’ long, in pairs, or often in clusters of 4, on distinct pedicels ;
lobes 3 times longer than the funnel-shaped tube, which bears the stamens
in the middle; filaments and style not much longer than the perigon;
capsule oval subcylindric, about 1’ long.

(9-12’ long and 3-34’ wide) leaves crowded around the base of the stalk
pale, glaucous, with small, almost black, spiny, straightish teeth, and with a
dark, horny margin toward the cuspidate tip, which terminates in a robust,
somewhat triangular, black spine 1’ in length; stout scape 8-12° high,
bearing a large, branched panicle of cream-colored flowers over 2’ in
length; perigon deeply 6-parted; lobes twice as long as tube, which bears
the long-exsert stamens in its throat; capsule broadly oval, sessile; seeds
larger than in either of the other species.

Rey. Mr. Greene noticed the abundant secretion of a sweetish liquid filling
the tube, which has also been observed in other species. The rootstock is
used as a substitute for soap by the natives, under the name of Amole,
much like that of Yucca, and, when roasted, is considered a great delicacy,
named Mezcal.

Acave Patmeri, Engelm. Agave, 1. c. 319.—Stemless; leaves lance-
olate, 10-20’ long by 2-24’ wide, attenuate into a slender, terete, narrowly
channelled, brown spine; marginal teeth flexuous or recurved, dark brown;
scape as in the last; panicle loosely branched; flowers 2’ long; perigon
whitish, lobes a little shorter than tube, stamens from its middle, and,
together with anthers and style, long exsert, purplish; capsule cylindric,

ZYGADENUS GLAUCUS, Nutt.—Colorado (950). Also from the Mogollon
Mesa of Arizona a form corresponding well with the description and with
other specimens, save in the shape of the gland, which extends across the
lobes of the perianth, but has sometimes no upward heart-shaped divisions
whatever (103), Loew. The shape of the gland, I am convinced, is quite
too inconstant to serve as a specific test. A specimen from Anticosti Island
has exactly the gland of Z. I’remontii, Torr., and yet is in all other respects
a good Z. glaucus.

ZYGADENUS ELEGANS, Pursh (Fl. N. Am. vol. 1, p. 241).—1-2° high,
slender, upper leaves few, one or two somewhat elongated but not exceed-
ing the stem; lower leaves narrow (4-6’ wide), equal to or exceeding the
stem ; pedicels in the developed flower 8-12” long, slender, exceeding the
narrowly lanceolate, thin, veined bracts; flowers “white” or yellowish-
white, 8-10” in diameter ; divisions of perianth oblong, obtuse, longer than
the stamens; racemes often paniculate at base; oblong ovules in two rows,
20-25 in each cell. In my specimens of this species, the glands are usually
deeply and obtusely two-lobed, with the lobes entire and the veins indis-
tinctly seen. In a specimen of Z. chicranthus, Rich. (for which species I a
first took this), from Fort Yukon, Alaska, the glands are less deeply lobed,
with the lobes truncate and distinctly toothed, and the veins quite plainly
seen. Not only do these shapes and divisions differ in the same species,
but often markedly in the same flower.

By Pursh, the flower is said to be white, the petals acute, and the
gland cinnabar-colored, in which points my specimens certainly do not agree
with the description. Mr. Watson, on comparing this with the plants in the
Cambridge herbarium, names it as above; and I do not hesitate to accept
his determination —Mogollon Mesa, Arizona, Loew (103); Willow Spring,
Arizona, at 7,195 feet elevation (243).

The Oregon form (probably the same with which Durand contrasted his V. Californicum in Plant. Prot-
ten. Calif. p. 103) Mr. Watson decides to be V. L’schscholtzii, Gray.

Comparing the specimen (395) from Mount Grabam with an eastern V. viride, Ait., I find the lat-
ter to have much longer (relatively) and more delicate filaments, and the wnopened anthers to bo just
a little retuse at the apex, giving them, when fully opencd, the appearance of a slightly four-lobed disk,

empty bract with a vagina 4-1’ long; stigmas 2—3 (1071-1072, 1070).

Drejer, Revista Critica, p. 57, says that the Greenland specimens of pulla
are two or three times larger and more robust than Iceland ones, occurring
with 1-3 approximate or very remote round ovate, acutish or elongated
cylindrical, obtuse female spikes; with scales obtuse, shorter, or acute,
longer than the perigynia; stigmas 2-3. In the Linn. Trans., Dr. Boott
states that Lapland specimens in the Linnzean Herbarium and the descrip-
tion in the Flora Lapponica prove C. pulla, Good., to be the original C. sax-
atilis of Linneeus, but that afterwards Linneus in the Flora Suecica and
the Species Plantarum confounded it with C rigida, Good, which has since
with European botanists generally borne the name of saxatilis. Hooker
and Arnott in the British Fl. consider C. Grahamii to be a variety of the
original saxatilis of Linnzeus. Anderson, Cyper. Scand., names it C. vesica-
ria, var. dichroa. Dr. Boott finally thought it to be the var. alpigena, Fries,
of vesicaria.

The following, belonging to the vesicarta group, with immature fruit,
do not admit of accurate determination or full description.

lapping, about 1’ long, rarely with a few female flowers at top and at bot-
tom; female spikes 2, 3-14’ long, 2’ wide, about 9’ below the male, 1-4’
apart; sometimes staminate at top, the lowest on a short peduncle; bracts
of the lowest male spike shorter than the culm, clasping, with connate pur-
ple auricles; bracts of the female spikes much longer than the culm, with
vagine {—}' long. In the vagina of the lowest spike, the lamina opposite
the bract is extended above to an obtuse point. Below the female spikes
there is sometimes an empty bract with a vagina 9” long; perigynia (very
young) squarrose, broadly ovate, abruptly ending in a stout, cylindrical,
obliquely cut, minutely toothed, strongly nerved beak, purple at the orifice ;
stigmas 3; scales 3-nerved, purple, with pale midnerve, the male oblong
linear, obtuse, the female lanceolate acute, as long as the perigynia. The
pale fruit and purple scales give the female spikes a variegated appear-
ance.—Colorado (460).

3-nerved, purple, with pale margins and midnerve, the male linear-oblong,
acutish, the female lanceolate, tapering to a sharp rough point, longer than
the perigynia.—Saguache Creek, Colorado, Wolf (1065). While the culm,
leaves, and male spikes in these specimens are fully developed, the female
spikes appear to have been arrested in their growth. In the disposition of
the spikes, they resemble aristata, but the short teeth of the perigynia
exclude them from that specics.

GRAMINEZE.

ALOPECURUS ARISTULATUS, Michx.—T win Lakes, Colorado, 1873 (1073);
Santa Ie, N. Mex., 1874 (82). Varies much in the length of the awn, which
is sometimes shorter, sometimes longer than the palet,—sometimes, indeed,
as in No. 390, Palmer, 1868, twice as long as the palet, in which case it
is hardly to be distinguished from A. geniculatus, L., of which it is consid-
ered a variety by Steudel. There is an equal variation in the stoutness of
the culm. ;

is supposed to be the Poa Andina of Nuttall, is exceedingly variable and
puzzling. It embraces several varieties, two of which are represented in
this collection, viz: Var. sprcata.—Radical leaves rigid, involute, scabrous,
pungently pointed, 3 to 9’ long; panicle narrow and spike-like; branches
sessile or nearly so.—Colorado, 1873 (1135, 1136, 1137). Var. masor.—

Poa TENUIFOLIA, Nutt. (Watson’s Botany 40th Parallel, Synopsis Flora
of Colorado).—This species presents a great variety of forms, some of
which may yet require to be made distinct species. The general characters
may be stated as follows: culms tufted, 1-24° high, stout or slender,
glabrous or with the leaves and sheaths more or less scabrous; leaves
narrowly linear, 1-10’ long, ligule short or elongated; panicle erect or
slightly bending, narrow or somewhat open and spreading, 2-6’ long;
branches 2—5 together, scabrous, of unequal length; spikelets 2—5-flow-
ered, glumes keeled, lanceolate or ovate-lauceolate, acute, scarious-mar-
gined, upper one 3-nerved, lower 1-nerved; flowers very narrow, linear or
linear-lanceolate, scarcely keeled, convex on the back, obtuse or acutish,
scarious, and bronze-tinged at the apex, puberulent or finely pubescent,
obscurely nerved, not webbed; flowers readily separating at the joints.
The grain is extensively gathered by the Indians for food. The following
forms or varieties occur in the collection: Var. riempa, Nevada, 1872,
Colorado, 1873 (1138 and 1140); var. ELoneaTA, panicle linear, 5-6 inches
long; Nevada, 1872; Colorado, 1873 (1141).

almost spicate panicle, which is 2-4’ long, 1-2 rays at each joint; spike-
lets lanceolate, 2-flowered, and with rudiment or continuation of the

This obscure grass was collected by Mr. E. Hall in the Rocky Mountains,
and in his collection was mixed with Poa tenuifolia; it was also collected
by the writer in 1868, on the expedition of Major Powell, and distributed
as No. 693 in his collection. Very fine specimens were also collected in
Middle Park, Colorado, in 1874, by Prof.G. H. French. It is at least very
close to, if not identical with, Graphephorum melicoides, some specimens of
which from Mount Kineo, Maine, show the short awn on the lower palet.—
