INTRODUCTORY.

Mr. Baker's ample and most interesting collection of the
year 1899 was made, as his own brief and pointed Itinerary
will indicate, along the borders of southwestern Colorado
and adjacent New Mexico. The field was one wisely
selected, as the large proportion of new plants obtained suf-
ficiently declares; while the great extent of the collection
shows how vast an amount of travelling and of other physi-
cal labor the zeal and industry of one strong and vigorous
young man can accomplish in a single season, and as it
were single handed.

Our report upon this rich and beautiful collection will
constitute Volume II of the PLANTS BAKERIAN.E. The
material has, at this date, for the most part been quite care-
fully studied, and it is hoped that at intervals not widely
separated the succeeding instalments of the volume may
reach the hands of the subscribers to the sets.

Inasmuch as this second volume will inevitably catalogue
many species that were reported in the first volume, the
names of such as are, as it were, duplicated in the collection
of 1899, will be printed in italics here, only such being ex-
cepted as were published as new in the first volume. The
names of these will be given in the usual small capital type.

ITINERARY.

By CARI, F. BAKER.

The first camp of 1899 was established early in March at
Hermosa, Colorado, at about 6,700 feet altitude, in the upper
Animas Valley and on the west slope of the Needle Moun-
tains. At this time, alder and the first willows were in
bloom, and a few days later the first Cymopterus appeared.
A few unopened flower buds of Townsendia sericea were also
seen. During this month special attention was given to
mosses, lichens and fungi, with good results. By April 1
Pulsatilla began to bloom.

On April 10 the second camp was made on the banks
of the San Juan River, just below the town of Aztec, New
Mexico, at an altitude of about 5,500 feet. This region is
characterized by sand hills and gravelly mesas, sparingly
covered with pifion pine and cedars, the whole very, very
dry. The hills along the extreme southern border of Colo-
rado do not differ essentially in many places from the Aztec
hills, and the distance is not great. Undoubtedly most of
the plants found at Aztec will also be found in Colorado.
Many things were coming into bloom when camp was made
at Aztec. During the month it was found that a very re-
markable and evanescent flora existed among these hills.
This flora appears during the very earliest warm days of
spring. The plants arise from perennial bases, flower and
fruit very rapidly, and have passed before hardly any of the
plants usually considered so characteristic of the region are
in their prime. Of most things, specimens were few and
scattering. Miles and miles of the interminable pinon hills
were tramped over to secure enough for issuance. On many
of the days, the cold northwest winds were extremely bitter,

IV PLANTS BAKERIANyE.

The statement that all plants in the '99 sets from this
locality were taken during April or the first few days in
May has seemed surprising, even to those best acquainted
with collecting in the southwest. Summer and fail collect-
ing in this locality would unquestionably give very inter,
esting results.

During the early days of May camp was moved far up
the valley of the Rio de los Pinos to the lower end of Gra-
ham's Park at an altitude of 7,800 feet. Here the results
of a cold, dry spring were very evident, and collecting was
poor.

On the 15th of the month camp was moved down the
valley to Los Pinos P. 0. (also known as Bayfield) on
the same river, at about 7,000 feet altitude. This place is
just north of the Ute Reservation line, and on the zonal
division between Pinus edulis (pifion) and Pinus ponderosa.
Here were still further signs of drought. Collecting was
necessarily largely confined to the river bottoms and ground
moistened by seepage from irrigating ditches.

On June 1 camp was moved to Arboles, in the river bot-
tom at the junction of the Rio San Juan and Rio Piedra,
only a few miles above the New Mexican border. Collections
were made here and also at Rosa, New Mexico. Numerous
large flocks of sheep were rapidly devastating the narrow
bottoms. The destruction could scarcely have been more
complete had the work been done by fire. A number of
very interesting plants were found among the very dry
sandy hills and along the stony mesa banks, — among them
a new Coleosanthus, two new Astragali, and a new Carduus.
As at Aztec, these hills are covered sparsely with pinon,
pine and cedar, though otherwise the two localities are very
distinct.

The next move made was up the Rio Piedra to Piedra

ITINERARY. V

P. O., at about 7,000 feet altitude and well within the
Pinus ponderosa zone. As will be seen from the Colorado
Forestry Commission map, this zone curves strongly to the
southeast, east of Durango, following the trend of the San
Juan range. The road up the Piedra valley is new and
extremely rough. An entire lack of bridges necessitated
fording the river many times. Frequently the wagon wheels
became wedged among the boulders of the river bed, com-
pelling the carrying out of the entire load through the ice
cold waters, by hand. Habenaria hyperborea was unex-
pectedly found about a cool spring in a dark shady gulch
near Piedra and a new Cypripedium at the same place.

During the last of July a move was made to Pagosa
Springs (at about 7,100 feet) over a good road passing
through magnificent forests of Pinus ponderosa. The end
of these forests is in sight, their destruction being actively
under way now. The desolation caused by the lumberman
and the fires which follow in his wake, is an evidence of an
appalling lack of foresight, not possible in the more scienti-
fically enlightened countries. In a favorable year Pagosa
Springs would unquestionably be the most promising head-
quarters in southwestern Colorado for mountain botanizing.
It is the center of a wonderful region, many distinct topo-
graphical areas being readily accessible. The unusually fine
hot springs at this place attract many tourists through the
season. Above this point are some of the finest natural
meadows in the State. Under ordinary circumstances, at
this season of the year there is still much snow on the sur-
rounding mountains. But in 1899 none could be seen and
the terrible drought was at its height. Sheep and cattle
were hurried up from the lower levels, though many died
of hunger and thirst. The most striking plant at this point
was Rhamnus Smithii.

VI PLANTS BAKERIAN^E.

About August 1 another move was made over a road
just built for mining purposes to Camp Loraine, in a
narrow basin between Pagosa Peak and Saddle Mountain,
at an altitude of about 9,000 feet. This whole basin is
richly watered by small streams, but sheep and drought
together had, during 1899, devastated the above-timber
country. From this basin as a base, expeditions by foot
were made for many miles about, over the surrounding
mountains, an elevation of 12,500 feet being reached at
several points. The results from above timber were very
disappointing, though as full advantage as possible was
taken of the richer vegetation below. Below timber line
these mountains are richly clothed with magnificent forests
of spruce — principally Picea Engelmannii. Deer and bear
were abundant here and mountain lion frequent. Black
grouse could also be had at any time. At this time should
be acknowledged many kindnesses received from a very
affable and whole-hearted gentleman, Mr. W. R. Black, of
Pagosa Springs, part owner of the promising Baritone
Wonder and Omaha mines near Camp Loraine. He gave
freely all the needed information as to trails, topography,
meteorology, and all similar matters. Camp at this point
was regretfully broken up on August 30.

A ten days' stop at Chama, New Mexico, completed the
season's work. During this ten days a trip was made up
on Cumbres Pass, where an elevation of 10,000 feet was
reached. But the sheep had been there first.

The collecting was done throughout by one person. It
would have been entirely possible to have accomplished far
more had the season and other conditions been more favor-
able. Whatever success was attained was due in no small
measure to the faithful services of the camp-hand, an Ala-
bama negro from Prof. Earle's station force. This man's

very unusual value lay not so much in his great strength
and endurance, as in the fact that he would do exactly as
told.

Throughout the field work constant reference was made
to the very useful and minutely exact topographical maps
lately issued by the Geological Survey, as well as to those
of the Hayden Survey. Mention should also be made of
the very interesting and valuable though not wholly cor-
rect map in the Biennial Report of the Forest Commissioner
of the State of Colorado for the years 1887 and 1888.

By the subjoined enumeration it will be seen that Mr*
Baker's collection of 1899 is rich in new species of Ascomy"
cetes, in this regard surpassing the collection made by
Baker, Earle and Tracy in the same general region in the
year 1898. The present list of species would have been
more extensive had not much of the material collected on
dead stems of herbaceous plants in early spring proven im-
mature and thereby indeterminable. Those of the same
habitat gathered in August, and even in July, were for the
most part in good condition. This is especially true of
species belonging to the Mycospserellacese, and the Pleo-
sporaceae. Specimens belonging to those families in which
the perithecia on hard-carbonaceous, such as the Amphi-
sphaaracise and Lophiostomatacese, usually contained recog-
nizable asci and spores which had been found the year
before, but were not in satisfactory condition.

Thanks are due to Dr. J. C. Arthur for aid in connection
with the Uredinales ; to Dr. L. M. Underwood for determin-
ing the species of Polyporus, and to Mr. David Griffiths for
careful cultural studies of the Sordariaceae.

tion there given in its somewhat larger size and slightly
smaller spores, but more particularly in the cinnamon-brown
of the crisped, continuous hairs and in the orange disc. In
the latter species the color is "dirty white," the hairs are
septate, and the disc has "no shade of yellow."

closely septate, the cells 2-3/x, long, when freed from the
ascus usually breaking into pieces, 12-16 feet long.

On barkless dead twigs of Amelanchier (n. 83), and Quer-
cus and Rlius (n. 84) at Hermosa, Colo., March. Ellis records
doubtfully three species of this genus as occurring in North
America. The first seems to have been a case of mistaken
identification ; and of the twoSchweinitzian species he is un-
able to give any account of the asci and spores. This new
one seems therefore to be the first fully authentic member
of this genus to be found in America.

LEPTOSPH^ERIA TYPH^E Karst. (?) Myc. Fenn. ii. 99.

On dead stems of Typha, at Hermosa, 30 March ; n. 33.

This differs materially from all other specimens of Lepto-
sphteria found on Typha in this country in the decidedly
smaller spores and narrower asci. Our specimens have the
asci about 60x12/4 and the spores only 20x5/4, while in
specimens of L. typharum (Desin.) Karst. the asci are
60-80x20/4, and the spores 25-30x7-8/4. Our measurements
of perithecia asci and spores agree closely with those pub-
lished for L. Typhse, but in our specimens the perithecia are
often densely cespitose in clusters of 6 or 8 to 20 forming
double or single lines and not "scattered" as described for
the European specimens.

LEPTOSPHAERIA VERATRI, n. sp. Perithecia scattered,

ends rounded, one of the medial cells usually slightly en-
larged, 20-25x5/*.

the spores are usually only 5-septate. It agrees quite closely
with the description of P. vulgaris Niesse., as given by Ellis,
N. A. Pyr. 339, but the spores are quite different from those
figured by Berlese in his Monograph PL 2 fig. 6 for P. in-
fectoria Fckl. to which species he reduces P. vulgaris.

On dead stems of Lepidium apetalum, Hermosa, 30 March ;

This approaches some of the smaller spored forms that
have been referred to P. herbarum. By some it would
doubtless be considered as belonging to that composite
species to which has been referred material from all the
continents and on hosts belonging to most of the larger
families of flowering plants. Such mixing of things can
serve no good purpose in classification.

A number of fuscous mycelial threads are usually to be
seen adhering to the base of the perithecium, but there are
no bristles about the ostiolum as in the closely related
genus Pyrenophora.

March; n. 20.

CYTOSPORA BOREELLA, n. sp. Stronea elevating the epi-
dermis forming a truncated cone 1mm. in diameter at base
and fmm. high; pycuidial cavities few, 2 or three to 5 or 6
in each strorna with ostioles united in a minute, emergent,
black disc, usually crowned by a scanty reddish-orange
gelatinous mass of exuded spores; sporules curved, hyaline,
6-8x1 iA*.

On dead willow twigs at Durango, March 19. Also at
Hermosa, 6 April, with Valsa boreella] n. 23.

This seems to be the spermagonial stage of what has been
called Valsa boreella Karst. A similar form on Salix from
Kansas (N. A. F. No. 3447) has been called Oytosptira mvea,
but our specimens are certainly not connected with Valsa
nivea. The exuded spore-masses are much the color of those
of C. chrysosperma, but they are much less copious and do not
t;ike the form of a tendril. The spores too are slightly
larger than in that species.

CYTOSPORA CORNI, West. Lamb. Fl. Belg. ii. 372. On
dead twigs of Cornus, Durango, Colo., March 20 ; n. 24.

This agrees with N. A. F. No. 3448 on Cornus asperifolia
from Kansas, which is named as above. The hard car-
bonaceous, frequently simple stroma indicates that it belongs
in Centhospora rather than in Cytospora.

PHOMA COLORADOENSIS, n. sp. Pycnidia scattered, rather
prominent, but covered by the epidermis and coming away
with it, black, lenticular, large, £mm. or more, of firm cel-
lular parenchyma, the cells 8-10/* in diameter, ostiole
papillate, at length broadly perforate; sporules cylindric,

straight or slightly curved, ends rounded, often minutely
biguttate, 8-10x3-4/1 ; sporophores not seen.

On dead stems of Pedicularis racemosa, near Pagosa Peak,
6 Aug.; n. 45.

This was previously collected by Mr. Baker on Pedicu-
laris, at Four Mile Hill, near Steamboat Springs in Northern
Colo., July 22, 1896. It was referred by Ellis to the com-
posite P. herbarum. It seems, however, to be sufficiently
distinguished from that assemblage of forms by its larger,
scattered and not gregarious hycindia. In this vast genus
spore characters alone furnish an insufficient guide to the
recognition of species.

PHOMA HERACLEI, n. sp. Pycnidia scattered, prominent,
black, subglobose, not collapsing, about £mm., finally ex-
posed by the shredding away of the thin epidermis, of firm
cellular parenchyma, cells 4-6x6-8^; shorules oval, hyaline,
usually with a minute gutta near either end, about 8-10
x6/i.

9,000 feet, 20 Aug.; n. 46.

PHOMA LUPINICOLA, n. sp. Thickly scattered on large,
often slightly whitened areas; pycnidia long covered by the
thin epidermis, black, prominent, subglobose, not collapsing,
about 150-175/i, membranous, of distinctly cellular paren-
chyma, cells 6-12/x. averaging 8/* in diameter, ostioles simply
perforate, the opening about 20/u, in diameter; sporules
numerous, regularly oval or subcylindric, ends broadly ob-
tuse, quite uniformly with a minute gutta at either end,
about 8-10x4-5/4.

MACROSPORIUM PUCCINIOIDES, Ell. & And. Bot. Gaz. (1891),
47. On dead twigs of Chrysothamnus, at Durango, 21
March; n. 34.

This striking fungus can hardly belong in the genus
Macrosporium. Its compact growth suggests the Tub&rcu-
lariaciae, rather than the Dematiacese. The only recognized
genus of the former family with mu'riform spores is Spegaz-
zinia, but our fungus differs widely from that genus in habit
and in that the corridia are not borne on sterigmata but on
the ends of the sporophores.

Common on dead stems of Sambucus, near Pagosa Peak,
9,000 feet, 25 Aug.; n. 73.

This is easily distinguished from T. Sambucina by the
larger softer sporodoche, the larger thicker conidiophores
and the much larger conidia. In specimens of the latter
species examined from Europe and from Wisconsin the
conidia are only 5-6x1 Jyu,.

TUBERCULARIA, sp. ? On dead branches of oak, Hermosa'
30 March; n. 74.

This is a very peculiar fungus. The large 2-3mm. sporo-
doches swarm with motile bacteria-like bodies. The coni-
diophores seem to be only 8— 12xl/* and variously branched
or united. The conidia are about 2-3x1 p. It is externally
brown, but vermilion-red within, and crumbling to a red
powder. It suggests the red stroma of some Endothia-like
fungus rather than a Tubercularia, but no perithecia could
be detected.

GRAMINE.E.

There is perhaps no section of the Middle West which
presents more interesting or important agrostological prob-
lems than does this field of our 1899 explorations and
researches. The pasturage is almost everywhere here most
excellent ; and even the alpine grassy slopes of vast extent
far above the limit of trees are converted into a sheep pas-
ture. And the still richer Piedra Meadows are famed
throughout the whole southern Rocky Mountain region.
The less elevated and more arid parts of the country have
also their own grass flora of much importance, and this sec-
tion in particular calls for careful investigation and experi-
mentation in relation to the preservation and propagation
of its forage plants.

In the determination of the species of the following list,
invaluable service has been rendered by Mr. F. L. Scribner,
to whom a set of specimens was sent for identification, and
by the late Mr. T. A. Williams. Later Mr. C. L. Shear furn-
ished some important additions and corrections. The
bibliographic citations and one or more alterations in
nomenclature have been supplied by Dr. Greene. The
somewhat extensive field notes are my own.

does not see how people who hold the law of priority to be
fundamental, can consistently adopt Savastana, over which
Hierochloe holds priority by more than forty years.

A. purpurea.

STIPA MINOR, Scribn. Bull. Agrost. xi, 46. At Cumbres
Pass, Colo., at 10,000 feet, Sept.; n. 218. The high open

175 from 12,000 feet, and n. 176 from 11,500 feet. Both are
common on the open alpine slopes and summits; and they
have been determined as unquestionable F. brevifolia by our
agrostologists, which is interesting in view of Dr. Theo.
Holms' statement that the true F. brevifolia is not known to
occur below the Arctic Circle.

among the spruce woods, and both occurring either singly
or in small tufts.

PROSPECTUS FOR THE COLLECTION OF 1901.

My botanical field work in the Rocky Mountain region, begun nine
years since, will be continued in 1901 and 1902, with better facilities and
under conditions otherwise more promising than heretofore. The speci-
mens will be of better quality. The determinations will be made by
those botanists who are most competent to deal with matter from the
West; thus making the collections authoritative, as representing in
herbaria the flora of the several regions explored.

In 1901, the summer and autumn will be given to the field from Mar-
shall Pass eastward and south westward to the boundary lines of Colorado;
a field, as far as known, exhibiting many peculiarites as to plant genera
and species, and therefore of the highest promise. The ground will be
covered as carefully as possible, at all elevations, i. e., from 4,000 to
13,500 feet. This will be our third and probably the concluding series of
our Colorado plants.

It is purposed to begin, in 1902, the exploration of a still newer field,
that of the more westerly State of Nevada ; and several years may be
devoted to that field, prosecuting the work throughout many of its
isolated and almost or altogether unexplored mountain ranges, and to
the western and southern borders of the State.

Subscriptions to all these series are now being received, and should be
registered as early as possible ; for the sets go out to subscribers in the
order of time recorded for the subscription, the fullest sets to the earliest
subscribers. Arrangements have been made whereby it will be possible
for any institution to obtain these sets. Correspondence is solicited.

A few short sets of the collections by Baker, Earle and Tracy in 1898
are still available. One good set of the 1899 collection, but lacking the
grasses, sedges and rushes, though very rich in the new species, remains
unsold. Its price is $73.

The distribution of mosses and liverworts from South America will soon
be made. These include many new species.
