GENERAL FEATURES OF THE REGION TRAVERSED.

i

The collections recorded in this series of papers were made
during a two years journey along the Pacific Coast and across the
continent of South America, the special object being the investi¬
gation of Medical Botany.

The route of travel covered regions the most diverse as re¬
gards all the conditions of plant life. North of Guayaquil the
coast is verdant, the luxuriant tropical vegetation reaching the
very water’s edge. But a short distance south of that city be¬
gins an entirely different region. The eastern cordillera of the
Andes divides South America into two portions, having almost
nothing in common. While only a few miles in width, this cor¬
dillera marks differences in soil, climate, and general appearance,
as great as any to be observed upon the globe.

Upon the Pacific side there is a very general dearth of mois¬
ture, rain being in many places almost unknown, while upon the
eastern slope rain is so constant that months may pass when the
sun is seen for scarcely an entire hour, and the humidity is so great
that clouds of rising vapor sometimes obscure the view of even
the nearest objects. The laden clouds that sweep in from the
tropical Atlantic lose little of their moisture in crossing the Ama¬
zonian basin ; any loss is but temporary, the equilibrium being at
once restored by the soaking up of a fresh supply from the enor¬
mous water surface that the region presents. But immediately
on reaching the mountains, great volumes of water are precipi¬
tated. The lightened clouds endeavor to escape upward, reach
the colder strata, and suffer fresh precipitations. This process is
continued over a belt of two hundred and fifty miles of steadily
increasing elevation, until the winds which cross the cordillera

(2)

178

carry only the merest traces of moisture. Throughout most of
this heavily watered region, the vegetation is of the densest char¬
acter. Allowing for the breaks caused by the streams, it might
be said that an arboreal animal, ascending a tree upon the An¬
dean foothills, could pass to the Atlantic without once descending
to the ground.

The species and genera of this eastern Andean region have
in general a very wide range. With the latitude, varies the alti¬
tude at which they grow. As we pass to the cooler southern
region, a species or its representative creeps down upon the
mountain sides. Thus, the Desfontainea spinosa, Remy., which
I collected abundantly in northern Bolivia, gradually descends,
until in the neighborhood of the cape, Lieutenant Safiford finds
it near the sea level, constituting a characteristic feature of the
landscape. Sometimes also, a species has its limits as to altitude
very narrowly and sharply defined, but will be represented at
successively lower elevations by other species exceedingly closely
related. Of this, the Cinchonas furnish us a striking example.
Each altitude has its own species — if species they can be called —
and they usually overlap to but a trifling extent. I have (in
two cases) looked along a mountain side where miles of Cinchona
Calisaya had been planted, and seen the upward limit defined to
within fifty feet by a line of dead or dying trees.

In general, we are disappointed by the scarcity of flowers as
compared with the abundance of plants. To this rule, trees and
many herbs are exceptions. But in the case of shrubs and vines,
of which latter there is everywhere a multitude, it is strikingly
true. It is probably to be accounted for by the steepness of the
land and a climate highly favorable for the reestablishment of de¬
tached fragments, torn away and carried to a new position. Un¬
able to obtain the light and air necessary for a high floral de¬
velopment, they have learned to depend upon a less complicated
method.

Turning to the western side, we find, as stated, a region in
which almost every condition is reversed. With more or less
scanty rains, strictly limited to a few months or even weeks, we
get a treeless and almost shrubless region, with a temperature
subject to very sudden and great variations. The amount of

179

(3)

moisture increases with the altitude. Upon our school-maps
great deserts are located on the table lands of this region. The
real deserts, however, are not there, but along the coast. Upon
the highlands there is sufficient moisture to redeem the country
from barrenness, and it is a fairly good stock country. As upon
the eastern side, so upon the western, the highland vegetation
creeps down the mountains as we go southward, until at Val¬
paraiso it reaches the ocean. North of Valparaiso there is thus
left a true desert along the coast, which widens as we go north¬
ward, until at the boundary of Chili and Peru, we find miles of
pure, absolutely barren sand. To the patient and industrious
botanist this coast desert will furnish a far more interesting field
than the luxuriant regions to the eastward. There is no regular
water supply, the showers being infrequent and spasmodic, with
years sometimes elapsing between them. But when they do oc¬
cur in sufficient quantity we find a rich and beautiful flora,
springing up, maturing and perishing in an incredibly short
period of time. What special provisions are required, and what
lessons in physiology are to be learned, while watching the pro¬
cesses of birth and extinction which are here going on ! Long
after the flora of the Amazonian basin shall have been satisfac¬
torily classified, this desert region will be contributing its annual
quota of undescribed species.

With this very meagre general outline before us, we shall
notice briefly the special localities where the collections were
made.

A part of a day each were spent at Guayaquil, Zorritos,
Payta and Coquimbo, and two or three days at Lima, but only
fragments were collected. Zorritos stands at the northern ex¬
tremity of the desert, and is watered with moderate frequency.
The Prosopis , Cereus , Amarantaceae and Chenopodiaceae, re¬
minded me strongly of the gravelly hills of the Mohave desert.
Payta is one of the dryest spots in the world, and Coquimbo is
but little better. Lima, like Tacna, stands near the foot of the
mountain. At the latter place a week was spent in the early
part of February. No rain had occurred, and the fifty species
collected were all from irrigated grounds. Tacna has one small
stream, conducted through the town by a paved channel, and it

180

(4)

does duty in great part as a sewer, besides furnishing the only
water supply. From Tacna, the route lay seven days by mule,
to La Paz. At nine thousand feet, 170 south latitude,* the veg¬
etation is sufficient to afford pasturage for the llama. At twelve
thousand feet we are upon the table-land, which is, in part at
least, volcanic, and at first thickly covered with loose rounded
stones. Farther on it becomes sandy and rocky by turns. We
cross many superimposed small ranges, and skirt the bases of
much greater ones. The landscape is much like that of our own
south-western plateau, except that there is less grass. What fre¬
quently appears like a grassy plain, proves to be covered with
plants like dwarf Hypochceris or Perezia , only an inch or two in
height, and presenting a green cushion of needles in the form of
spines terminating the erect linear leaves. Numerous species
of Adesmia , rarely rising above a foot from the ground, and often
very closely prostrate, cover much of the country.

Near the eastern verge of this tabie-land, in a basin two
thousand feet deep, with nearly vertical walls of clay or gravel,
is situated La Paz, at an elevation of about eleven thousand feet.
Here I spent some two weeks during the months of February,
March and April, collecting one hundred and fifty or more species.
This was during the latter half of the rainy season, when the
walls of the basin, and the gravelly and rocky hills along the La
Paz River to the south, were richly clothed with plants in flower.
The remainder of the time during this period was passed across
the range in Yungas. Returning early in April to the coast, I
proceeded to Valparaiso, where three months were spent. Here
the season is earlier, and winter was just setting in when I arrived.
A winter there is about the same as in northern Florida, the
orange surviving, but not thriving. Some twenty-five or thirty
stray specimens were found in flower before I returned to La
Paz. It being then early in June, I found a dry and wintry
season prevailing, with a most dreary prospect for a collector.
Fora longtime business detained me in the city, save for a few
short excursions across the mountains, and one long stay in the
province of Yungas, made, unfortunately, at an unfavorable season
for collecting. Just as the rains were beginning the next Janu-

* Distances, latitudes and altitudes a,re given approximately.

(5)

ary, I was obliged to leave La Paz on my journey to the Atlan¬
tic. Thus, out of almost a year spent in this interesting region,
fortune had favored me with only about two weeks favorable col¬
lecting. But extensive collections had been made meantime
upon the eastern slope at Unduavi and Yungas. Unduavi is one
of several little hamlets upon a mountain stream in the first valley
to the eastward of La Paz. But I have characterized by this
name the entire collecting station constituted by this valley and
its enclosing mountains. At 12,000 feet begins the semi-alpine
flora generally associated with Aspidium aculeatum and the
smaller species of Acrostichum. At 10,000 feet the shining,
coriaceous leaves of the tropics begin to be seen, and at 8,000
feet the vegetation is truly tropical, including bamboos, fuchsias
and begonias. The whole surface is characteristically rocky, the
soil being very scanty indeed, but rich. At Unduavi, between
8,000 and 10,000 feet, I collected 150 species in flower in Octo¬
ber, in three days.

Crossing the northern wall of this valley, we find upon the
summit, at about 1 1,000 or 12,000 feet, a cold, boggy and cloudy
region, where sphagnums and long drooping lichens abound.
Upon the other side we are in Yungas, referring not to the polit¬
ical boundary, but to my collecting station of that name. De¬
scending to 7,000 feet, we enter the great Andean forests which be¬
come heavier and heavier, though scarcely denser, as we descend.
The trunks and greater branches are scarcely to be seen for the
epiphytes upon them, chief of which are orchids, bromeliads,
ferns, mosses and aroids. At 5,500 feet we strike the coca and
cinchona belt, and at 4,000 feet we find the heat becoming op¬
pressive and the air sultry. From 3,500 to 5,500 feet is prob¬
ably the region of greatest rain-fall. The Yungas collections
were chiefly made at elevations of 3,000, 4,000 and 6,000 feet.

Leaving La Paz on the 10th of January, 1886, we were at
once overtaken by the unprecedented rains of that season. At
Sorata, on the base of Mount Iliampu, we were detained by
floods from the latter part of January till about the first of March.
But little could be dried, and that little with the greatest diffi¬
culty, many of the collections being repeated once and some of
them twice, In transit to the coast moreover, the continuous

(6)

182

rains succeeded in penetrating some of the bales. A fine and
little known alpine flora exists on Mt. Iliampu. The altitude
and conditions of this locality are a parallel of those of Unduavi.
One day’s journey to the northward we reach Ingenio del Oro, a
gold washing establishment. This locality is also very similar to
Unduavi, but has the richest flora (March) of any locality that I
have ever visited. It is above timber line. Three days of mis¬
erable exposure were passed here, and all our collections spoiled.
Two days more brought us to Mapiri, a section almost precisely
like Yungas, where, at 2,500 to 5,000 feet, I remained during
March and April, improving the fairly good weather in making
enormous collections, which arrived home, after great vicissitudes,
in very fair condition. Mapiri is the great centre of Cinchona
culture in South America, and large collections of these plants
were made, among them being many new hybrids. The run of
eighty-four miles to Guanai, 2,000 feet elevation, was made on
rafts by the force of the current in a little less than eight hours.
Arriving at Guanai three weeks earlier, we should have encoun¬
tered one of the most interesting floras in South America. How¬
ever, as we lost nearly everything collected at this place, it mat¬
tered but little. The forests at that point consist almost wholly
of Mimoseoe , in prodigious variety. These had all gone to fruit
and made rather ill looking specimens. At this point the succu¬
lent plants, such as Begonia , Oxalis and Bromeliacese began to
appear much less prominent. I had early abandoned the collec¬
tion of such plants, foreseeing that they would crowd out all other
work, owing to the unlimited time necessary to dry them.

Upon new and larger rafts we floated in eight days to Reyes,
the mountains becoming smaller, and the banks lower and lower
as we proceeded, until, just at the port of Reyes we cut through
the outermost range of the Andean foothills. Here, at an alti¬
tude of 1,500 feet, the forests are broken by patches of pampa,
which are projected into them from the South, and the varying
conditions of lake and river, forest, plain and bog, produce a flora
of surpassing interest. Nearly two months were passed in Reyes,
and although sickness materially interfered, a handsome repre¬
sentation of between 400 and 500 species was secured. The
whole of this collection, with the most of what we had brought

183

(7)

from Guanai, 9,000 specimens in all, was found one morning
sunken with our boat under fifteen feet of water. From this
point on down the Beni, the country rapidly assumes the char¬
acter of the Brazilian forest, with a dense tangle in the sombre
shade below and a wealth of floral life high above upon the tree
tops. The month of July was passed in journeying down this
river and making occasional short stops to collect. At the junc¬
tion of this river with the Madre de Dios, the centre of the rub¬
ber production of that district, two months were spent, and the
finest part of my collection was prepared. Just below this junc¬
tion begins the series of falls produced by the river’s cutting its
way through a series of low hills. During the two months that
were required to make the tedious transit of these falls, I had
ample time to complete my collection with a handsome addition.
Many of the Andean species with which we had already become
familiar, here re-appeared.

The entire collection includes somewhere about three thous¬
and numbers, of which an average of ten specimes were collected.

An Enumeration of the. Plants Collected by H, H, Rusby, in
Bolivia, 1885-1886.— II.

By Elizabeth G. Britton.

MU8CI.

There has been a long delay in publishing this portion of the
enumeration of Dr. Rusby’s collection, because at the time that
the first comparisons were made at Kew in the summer of 1888,
I felt that further study, and, in many cases, better material would
be necessary in order to accurately determine many of the species.
Furthermore, all of Mandon’s specimens, which were collected in
the same localities which Dr. Rusby visited, such as La Paz and
Sorata, were still lying in Schimper’s herbarium undescribed and
bearing only manuscript names.

In all instances when Dr. Rusby’s specimens agreed with
Mandon’s the latter have been cited by number and locality, but
as we did not possess at that time a set of Mandon’s mosses, and
my time at Kew was limited, it was impossible for me to write de¬
scriptions of all of the new species preserved in Schimper’s her¬
barium collected by him. Hoping, however, that some one better
fitted to do this than myself would have the opportunity of study¬
ing these Bolivian mosses, and also in recognition of the special
privileges accorded to me at Kew while studying there, the first
and most complete set of Dr. Rusby’s duplicates was deposited
there. The second set was sent, after having been carefully
studied and named as far as possible by one unacquainted with

472

(10)

Tropical American genera, to Dr. Carl Muller, at Halle. He
treated them in the same way that Schimper did Mandon’s, giving
most of them manuscript names, making few or no critical com¬
parisons, and furnishing no descriptions. As far as we know,
they are still lying in his herbarium unpublished.*

When we went to Europe, in 1891, I again took with me all
the doubtful species and those supposed to be new, for the sake of
making further comparisons at Kew with Schimper’s specimens.
In several cases, as shown in the text, I found that Dr. Muller was
mistaken, and that my original determinations were correct; in
several others I found manuscript names of Schimper’s given to
Mandon’s specimens which had priority over those of Muller’s
given to Dr. Rusby’s specimens. In several other cases the types
were not at Kew, and the specimens had to be referred to William
Mitten and Emile Bescherelle for further study. We visited Mr.
Mitten and I showed him and gave him several species, the
types of which were in his herbarium. He very kindly made the
comparisons for me, and in several cases shared his specimens
with me.

We also took a set of the duplicates for M. Bescherelle, and I
spent a day with him at the Jardin des Plantes in Paris looking up
some of Mpntagne’s types. In a letter received from him at Kew
he says :

“ As for the mosses collected in Bolivia by Mandon, I think I
remember that they were distributed by me in 1869, after the
death of Mandon, which occurred on the 30th of December, 1866.
Schimper named them, but did not describe or diagnose them.
All of Mandon’s mosses, Bolivian and Madeira, were sent to me
by M. Cosson to be made up into sets, which were sold for the
benefit of the widow. I kept one set and the residue, and pro¬
posed publishing at least the list of new species with the numbers
and localities, in order to save Schimper’s priority in the new dis¬
coveries. Unfortunately, other occupations have prevented my
accomplishing this project. It will give me pleasure to share with
you my duplicates.”

We have to thank M. Bescherelle for a very good set of Man¬
don’s mosses and we were also fortunate enough to secure Dr.
Spruce’s own private set of his Musci Amazonici et Andini, so

* Since this manuscript was sent to the printer we have learned that Dr. Muller is
proposing to publish a Brylogia Boliviana in the Nuovo Giornale Botanico Italiano.

473 (11 )

that we are now better able to study and compare Dr. Rusby’s
specimens.

In 1893 we received a. much larger collection of mosses than
Dr. Rusby’s, made by Mr. Pierre Jay in northern Bolivia, also
from the vicinity of La Paz and Sorata. I again wrote to M. Besch-
erelle, offering to send him a complete set if he would name
them. He replied that he was so occupied with his studies of the
mosses of Japan that he found it impossible to undertake it and
that it was a thankless task acting as secretary for some one else.
I might, perhaps, have been strongly tempted to take the same
stand had there not been twelve pages skipped in the reprints of
Dr. Rusby’s enumeration and held in reserve for this list of
mosses. Just as we are going to press I have received a pos¬
tal card from M. Emile Levier, inquiring for the Bang collection
of Bolivian mosses and telling me that Dr. Carl Muller is printing
in Florence a Bryologia Boliviano, \ As my manuscript is completed
and the priority of Schimper’s names from Mandon’s collections is
maintained throughout, we think it best to publish our enumera¬
tion independently.

This summer I have also commenced wrapping and sorting
Mr. Jay’s collections and have found several of Dr. Rusby’s new
species in fruit, which had previously only been collected sterile,
so that the work promises to be of great interest, but will take a
good deal of time to accomplish with the limited collection at my
disposal and the pressure of other duties. However, it seems best
to publish the list of Dr. Rusby’s collection as it stands, first with
such determinations and descriptions as I now know to be correct,
and to modify and amend this list subsequently as I find time to
study and compare the fine collections made by Mr. Jay.

The sequence of genera followed is nearly that given by Mitten
in his Musci Austro-Americani (Journ. Linn. Soc. 12: 12-25.
1869). Thirty-nine genera and ninety-six species are enumerated
in this collection of which forty-two are new or previously unde¬
scribed. Six mosses, as many hepatics, four lichens and a few
algae and fungi were also collected in Bolivia by A. M. Bang and
enumerated by Dr. Rusby (Mem. Torr. Bot. Club, 4: 273).
These were named by Mr. Wright at Kew, but the Sphagnums have
since been examined and corrected by Dr. Warnstorf from speci¬
mens preserved in the Boissier Herbarium at Geneva.

Leptodontium gracilescens C. Muller. Yungas, 6000 ft. (3108);
Sorata, 8000 ft. (3108a) fide C. Muller. E. Bescherelle says:
“Affine L. luteo foliis tamen patulis haud appressis or minus
longe cuspidatis dififert.”

At Kew in Herb. Hooker there are four specimens of Jame¬
son’s from the Andes of Quito, labelled Didymodon luteum , evi¬
dently the types of Hook. Lond. Journ. 5 : 48. No. 174 is anno¬
tated by Wilson : “ var. foliis magis recurvis patenti-recurvo ser-
rulato.” A part of 143 has the leaves much recurved as in 193b,
both of which are sterile. On the same sheet is a specimen of G.
Mandon’s Plantae Andium Boliviensium Exsicc., no 1616, from
vicinius Sorata labelled Didymodon luteus Taylor, which quite
agrees with Rusby’s specimens in its bright yellow recurved
leaves, longer pedicels two or three in the same perichetium, and
capsules twice longer than Jameson’s specimen’s.

Leptodontium gracile C. Muller, n. sp. Mapiri, 5000 ft (3111);

Unduavi, 8000 ft. (3109).

Plants bright yellowish green, stems slender, leaves squarrose
and curled when dry; cells densely papillose and obscure above,
clearer and oblong below, margins entire and recurved to above
the middle, sharply and doubly serrate above. Plants all sterile.

Plants dark and discolored below, tips of the branches bright
yellowish green, stems 3-4 cm. long, leaves squarrose, spreading
and curled when dry, remaining undulate when moist, margins
entire and recurved below with a few protruding teeth above, vein
generally excurrent into a cuspidate apex, cells clear but papillose
at base, densely and finely papillose above. Plants sterile.

(13)

There is no specimen in Schimper’s Herbarium at Kew bear-
ng this name, so no comparison was possible. These specimens
of Dr. Rusby’s have the leaves strongly costate to the apex, the
costa is papillose on the back, the margins are entire below,
serrate and recurved above, papillose and undulate, the upper cells
are small and round, but not opaque, the basal cells longer and
brown.

Holomitrium Bolivianum C. Muller, n. sp. Near Yungas, 4000
ft. (3190).

Plants in light yellowish tangled mats, mixed with hepatics ;
stems 3-4 cm. long, flexuous and matted, with light-colored
tomentum ; leaves 3-5 mm. long, linear lanceolate, twisted and
curled when dry, costate to apex, serrate and papillose above as
well as undulate, entire with revolute margins below; cells round
and small, lower ones hyaline. Plants sterile.

This species was compared with H. flexuosum Mitt, at Kew,
but it differs from No. 21 Spruce from Andes Quitenses in the
leaves, nor does it agree with any other species from this region
at Kew. It should be compared with H. longifoliinn Hpe.

Dicranella angustifolia Mitt. Near Yungas, 4000 ft. (3112).

Dicranella nanocarpa C. Muller, n. sp. Near Yungas, 4000
ft. (3139 pp).

Stems 3-5 mm. high, simple or branching, leaves erect or
slightly secund when dry, uppermost often 2 mm. long, linear-
subulate, margin entire, vein excurrent with a few indistinct teeth
at apex ; perichetial leaves broader and clasping at base. Dioeci¬
ous. Pedicels 5-8 mm. long, twisted above, bright orange; cap¬
sule erect, ovoid, less than .5 mm. long, with a longer straight beak
on the lid than the theca, which becomes broad and hemispherical
when empty ; mouth with a dark border, peristome red, teeth fuga¬
cious ; cells of the walls oblong or hexagonal in regular rows.

Only six plants found mixed with a specimen of Philonotis , No.
3139; the alliance was not determined.

Dicranum spectabile Sch. mss. Unduavi, 12000 ft. (3113.)

Plants stout and large, much discolored at base, glossy and
yellow at the tips of the branches; stems 10-15 cm. long, decum¬
bent, branching by short innovations, tomentose in the axils of
the leaves, often slender and interruptedly foliate ; leaves longest
at the tips of the branches, often 15 mm. in length and 1 mm.
broad at base, to a concave apex with involute margins, entire
below, serrate, becoming spinose along the excurrent vein ; basal

(14)

476

cells larger and brown, a few hyaline ones near the vein, others
conspicuously porose, becoming long, spindle-shaped above and
oblique along the margin. Monoecious antheridia in small buds
on the tomentum in the axils of the leaves. Pedicels 15-20 mm.
long, much twisted to the left ; capsule 3-4 mm. long, erect, smooth,
ovoid, largest at base, abruptly contracted or with a short neck ;
lid with a slender oblique beak 2 mm. long ; mouth small, teeth
short, slender and bifid.

Compared with and equal to Mandon Plantae Andium Bolivi-
ensium, No. 1609. Hab. vicinius Sorata, also Songo, 1857.

Nearest to D. speciosum Hk. & Wilson. Compared with No.
325 of W. Jameson’s PI. Aequatoriales from which it differs in
its more slender habit, shorter leaves and pedicels half as long.
Dr. C. Muller, also recognized this as a new species.

Dicranum species? Yungas, 6000 ft. (3115).

These specimens are sterile, and have baffled Dr. Muller, and
Mr. Mitten as well. They have been compared with all the speci¬
mens at Kew likely to be the same. Mr. Mitten sent me a por¬
tion of his specimen of Dicranum Mittenii CM., but they do not
agree. Dr. Muller named them Campylopus concolor Hook., but
they were compared at Kew with specimens in Hooker’s herba¬
rium collected by Lindig in Bogota, and they differ in being much
stouter plants of a glossy yellow color, with longer and broader
leaves, which are serrate only at the apex and have a much broader
blade.

Pilopogon gracilis Hook. Near Yungas, 6000 ft. (31 59 in part).

Compared with Hooker’s specimens at Kew collected by Wed¬
dell in the Province of Yungas, Bolivia, May, 1847, with which
they agree in every way. The leaves are hyaline at the basal an¬
gles and these cells extend up along the margins; the short trans¬
verse walls of the cells are thickened ; the vein is broad, the
margins incurved, and there are a few teeth at the apex. The
perichetial leaves end in a very long tip, often extending half the
length of the pedicel.

Dr. Muller gave this a manuscript name under Catagonio.

Campylopus trivialis C. M. n. sp. Mapiri, 2500 ft. (3196).

Plants loosely matted, dirty green; stems flexuous, not rigid,
3-5 cm. long, usually simple, occasionally with crowded branches

477

(15)

at the apex of the stems ; stem leaves short, 3-5 mm. long,
slightly falcate at the tips of the branches, tubular with incurved,
entire margins ; vein more than one-third of the width of the base
of leaf excurrent with a few teeth at apex ; basal cells thin, hyaline
to the vein, not colored.

Plants sterile and much less rigid than is usual in this genus;
their alliance was not indicated nor determined.

Campylopas sp. undetermined. Yungas, 6000 ft. (3116).

Plants fragmentary and broken. Stems 2-3 cm. high, prolifer¬
ous with fasciculate branches at apex, branches often 15 mm. long
with the leaves crowded at the summit ; leaves curled and twisted
when dry, 3-5 mm. long, blade narrow, forming a serrate border
of one row of cells almost to the apex ; vein papillose on the back ;
cells enlarged at base, brown at angles; leaves of the branches
shorter, often entire, and radiculose at base, perichetial leaves very
long pointed, costate, entire, or scarcely serrulate ; cells much en¬
larged at base, brown, upper oblong; antheridia in heads matted
with brown radicles; pedicels several in the same head, 8-10 mm.
long, curved, becoming erect where dry; capsules. 1.5 mm. long,
ovoid, not ribbed when dry ; peristome red, lid not seen.

These specimens are closely allied to C. annotinus Mitt., and
C. brachyphyllus Mitt., and C. multicapsularis Sch., from all of
which they differ in the leaves and the smooth walls of the cap¬
sules when dry.

Grimmia nano-globosa C. M. n. sp. Mapiri, 5000 ft. (3195).

Plants pulvinate in gray cushions, stems 5-8 mm. high ; leaves
crowded with a long, rough, white hair-point, blade carinate, cells
small, almost quadrate, sinuous, basal ones elongated. Dioe¬
cious (?). Perichetial leaves with a long sheathing base, the white
tip reaching the lid of the capsule. Pedicel erect, straight, 3-4 mm.
long; calyptra lobate-mitrate, capsules I— 1 .5 mm. long, lid with a
straight beak, .5 mm. long ; annulus narrow, of several single
rows of cells falling in fragments with the lid; peristome red;
teeth short, papillose; spores smooth, .008-.010 mm.

A smaller species than either G. ovata Web. & M., or G. longi-
rostris Hook.

Compared at Kew with Matthews’ Peruvian specimens labelled
G. ovata and illustrated by W. Wilson. The Bolivian specimens
are smaller.

by Mr. C. H. Wright with the permission of the Director.

Grimmia (Racomitrum) dimorphum C. Muller, n. sp. Unduavi,
ioooo, ft., Oct., 1885 (3118).

Plants in dark dirty mats, stems blackened beneath, decum¬
bent, giving off lower branches 3-4 cm. long, branchlets short,
fasciculate ; leaves subsecund, incurved and twisted when dry,
spreading when moist, carinate, plicate with one strongly involute
margin, generally blunt apex, but occasionally with a white mu-
cronate tip or the apical ones with white crisped tips, vein promi¬
nently keeled, ending below the blunt apex or continuous into the
white prolongation ; cells all uniformly sinuous, elongated with
faint transverse walls; perichetium short, 3 mm. long, broadly
convolute, sheathing; bracts broad, apex acute, cells scarcely sin¬
uous. Pedicels short, less than 1 cm., long, arcuate, twisted ;
capsule erect, or bent, 3 mm. long, smooth except just below
the small dark bordered mouth ; lid I mm. long, conic beaked,
teeth long, slender, papillose, yellow.

Compared with R. crispipilum Taylor in Herb. Hooker, nos. 1 35,
a , b ; Spruce Musci Am. et And.

Leaves less cirrous pointed than 135 b; stems shorter than
135; leaves exactly alike; capsules on shorter pedicels, less cylin-
dric, shorter and broader, with a broader mouth. General aspect
quite different.

Leucobryum longifolium Hpe. Mapiri, 2500 ft. May, 1886
(3II9>

Sporophyte immature. Agrees with no. 71 c. of Spruce’s
Musci Amazon, et. And. and with no. 7169 of A. Glaziou from
Rio Janeiro, both at Kew.

Leucobryum strictum C. Muller, n. sp. Unduavi, ioooo ft., Oct.,
1885 (3119a).

Plants short, loosely tufted, mats dull gray when dry, stems
short, decumbent at base, less than 2 cm. high, brown when moist,
with light tips ; leaves erect and slightly spreading, iridescent
when dry, about 1 cm. long by 2 mm. broad, concave from a
broad white base, tubular and dark above the middle, margin nar¬
rowly hyaline, apex with a few brown cuspidate teeth.

Plants sterile, smaller and darker than L. indans (Brid.). “Ab
L . longifolium Hpe., cellulis chlorophyllis tantum latioribus differt.”

* Tortulaceae.

The treatment of this group by Mitten in his “ Musci Austro-
Americani ” is far from satisfactory. It has seemed best, however,
to follow him in this as in the other families. Duplicates of these
were not sent to Dr. C. Muller, as they had not been carefully
studied nor compared at that time. Later M. Bescherelle had a
set of them, and made one or two comparisons for me with Mon-
tagne’s types at the Jardin des Plantes. It will require more study
and comparison with a more modern treatment of the family,
before the specimens listed can be thoroughly understood.

Tortulci ( Trichostomuni ) contortifolium Mitt.? Unduavi, 8,000
ft. October, 1885 (3126).

There were no specimens of this species at Kew; hence these
specimens were named only from the description on page 147 of
Mitten’s Musci Austro- Americani. They were shown to Mitten
and sent to M. Bescherelle, but should be compared with Spruce,
“ No. 213, Andes Quitenses, Chimborazo (10000 ped.)”

Tortula ( Trichostomuni ) semivaginatum Sch. mss. in Herb., no.
1618. Mandon, Plantae Andium Boliviensium. De Capanuta
a Songo, 18 Obr., 1857, in Herb. Schimper. Vicinius So-
rata, April, 1858, in Herb. Hooker. Near Yungas, 4000 ft.,
1885, in Herb. Rusby, no. 3128.

Plants 2-3 cm. high, dark below, red-brown above; stems
simple or branching by subapical innovations 1-2 cm. high;
leaves curled and twisted when dry, spreading when moist from
an erect, glossy clasping base, the lanceolate blade 2 mm. long,
suddenly bent and contracted from the hyaline base, 1 mm. long,
upper cells small, dense and with thickened irregular walls and
small, blunt papillae, decurrent at the margins a short distance on
each side of the clasping base, vein large, yellow, ending in the
acute apex. Dioecious? Perichetial leaves smaller, with a longer,
more sheathing base. Pedicels 5-15 mm. long, twisted in two
directions ; capsules 2-3 mm. long, straight, cylindric, smaller at
the mouth; lid with a long curved beak, annulus large, falling
with the lid ; peristome fragile, pale, papillose, teeth long and
slender, thickened and united at the basal joints, not twisted.

Closely related to T decolorans Hpe., from which it differs in
its larger size, longer, more spreading and clasping leaves and paler
not twisted peristome.

Tortilla (. Barbnld ) campylocarpa Taylor. Unduavi, 8000 ft.
October, 1885 (3127).

Compared with Spruce Musci Am. et And. nos. 185 and 201,
agrees with specimens at Kew and has been verified by Bescherelle.
Also compared with T. rectifolia Taylor, nos. 193-196, Spruce,
from which it differs in its larger size and longer, more acuminate
leaves.

Barbula austro- revoluta Besch. mss. Near La Paz, 10000 ft.

April, 1885 (3129).

Plants in dense light yellowish-green or slightly glaucous, and
dirty tufts; stems 1-2 cm. high with numerous, slender, subapical
branches; leaves erect-spreading when moist, spirally twisted
around the stem when dry, small, 1 mm. or less long, with strongly
revolute margins and a broad, thick, yellow vein, ending in and
forming the blunt apex ; lower cells oblong, clear; upper smaller,
denser and papillose ; dioecious (?), perichetial leaves with a
longer, more hyaline, clasping base. Pedicels light yellow, 5-7
mm. long; capsule 2 mm.; lid conic-beaked, cells spirally formed ;
peristome immature.

Closely related to no. 1622 of Mandon’s Bolivian Mosses, col¬
lected in April, 1856, near Sorata, and labelled B . glaucescens in
Herb. Schimper, but differing in the shorter, more blunt leaves,
the more revolute margins, and in the yellow pedicel. Bescherelle
says of it, “B. revoluta affinis sed foliis magis obtusa acuminatis
glaucescentibus cucullatis ; pedicello flavo, peristomio longe
distat.”

Tortula ( Syntrichia ) sp.? Near Yungas, 4000 ft., 1885 (3124).

Unduavi, 8000 feet. October, 1885 (3125 and 3127 pp).

Plants in dirty, yellowish-brown tuffs; stems 1-1.5 cm. high,
branching ; much abraded and discolored below; leaves erect-ap-
pressed when dry, tufted on the stems, upper, green with white
hair-points, the vein papillose on back, and excurrent into a rough
awn, apex rounded, margins involute ; upper ceils densely papil¬
lose, low?er, clear and hyaline. Dioecious? Seta 10-12 mm. long,
red below, twisted ; capsule narrowdy cylindric, 1 mm. long,
straight or slightly arcuate when old, with a long-exserted colu¬
mella ; mouth small, annulus narrow, falling in fragments when
old ; peristome short or broken, twisted from a short basal mem¬
brane ; teeth pale, papillose.

These plants were compared with several of Mandon’s Plantae
Andes Boliviensium, but their alliance was not determined by me
while at Kew, nor by M. Bescherelle, to whom they were subse¬
quently submitted.

481 (19)

Tortilla ( Syntrichia ) Andicola Mont. Unduavi, 8000 ft. Octo¬
ber, 1885 (3120). Sterile plants only collected.

Large sterile specimens answering the description given in the
Ann. Sci. Nat. (Series 2, 953) and compared at the Jardin des
Plantes with the type collected by D’Orbigny near La Paz, in the
Bolivian Andes.

Tortilla ( Syntrichia ) aculeata Wils.? Mapiri, 5000 ft. April,
1886(3123); Sorata, 10000 ft.

Compared at Kew with Spruce, no. 144 and Jameson’s speci¬
mens from Pichincha, both cited by Mitten under the description
of this species. Ours agree with Jameson’s better than Spruce’s
no. 144, and it would seem as if the two were distinct or the
species very variable. Bescherelle also seems to think there is
room for separation here, as he says : “ T. aculeata Wils. affinior
sed primo viso differt. Foliis integerrimis, magis papillosis, duplo
longioribus, pilo valde longiore diversa, ut videtur — forsan species
nova ?

Tortula (Syntrichia) bipedicellata n. sp. Bescherelle, M. S.

Mapiri, 5000 ft. May, 1886 (3123a).

Plants in small yellowish-brown tufts; stems 1-2 cm. high;
leaves not crowded, curled and twisted when dry, 3-4 mm. long,
without a hyaline point, the vein stout and brown, but ending in a
short mucronate point at the apex of the leaves; margins plane
or rarely slightly revolute below; upper cells densely papillose,
lower large, clear and oblong. Dioecious perichetial leaves not
differentiated. Pedicels mostly two together, about 1 cm. long,
straw-colored; capsules 3-5 mm. with a long beaked lid, straight
or slightly curved ; mouth small, red ; peristome not developed.

Closely related to T. glacialis Kze. Compared at Kew with
Weddell’s no. 20, collected in Bolivia, province of Larecaja, June,
1847, with which it agrees in the leaf characters but differs in hav¬
ing the pedicels more uniformly in pairs. There is a mixture
also in this species at Kew, for the specimens collected by Lieb-
mann on Mt. Orizaba and Poeppig in Chili are very different in
aspect. Brescherelle says of them : “ Affinis T glacialis Kze.,
foliis tamen duplo-longioribus, ad summum planis haud undu-
latis ; capsula geminore, peristomio non afformato.”

Tortula fragilis Taylor? Sorata, 10000 ft. (3121).

Compared with' specimens at Kew collected by Lindig, New

(20)

482

Granada, 2075, and Jameson’s, from the Andes of Quito, 1847. Our
plants are larger than Lindig’s, the capsules longer and the pedicels
single. The leaf is broadly undulate, ending in a short cusp, the
marginal cells short, quadrate and papillose, the basal cells oblong
and hyaline. The basal membrane of the peristome is very short,
the teeth twisted once, white and granulose. Bescherelle says of
this: “ Folia ad basin margine recurvis, cellulis inferioribus simili-
bus differe mihi videtur. 7. fragilis (N. Grenada, Lindig, 2075)
folia basi plana, ab cellulis marginales inferiore minores ut margi-
natahabet: an T. fragilis forma peculiars ?”

lortula Pichinchensis Taylor ( Barbula affinis Hpe.). Ingenio
del Oro, 10000 ft. (3122).

Compared at Kew with Spruce’s nos. 185, 194, 197, 200-202
Andium Quitensium. Also verified by M. Bescherelle.

Orthotrichum pariatum Mitt. Sorata, 10000 ft., Feb., 1886

(3130).

Compared with no. 130 Spruce, And. Quit., with which it
agrees.

Macromitrium Rusbyanum E. G. Britton, n. sp. Unduavi 12000

ft. October, 1885 (3188).

Plants large and showy in yellowish-brown tufts; stems 9-10
cm. long, repeatedly branching; leaves brown, broken and abraded
on the lower parts of the stems, light yellow, longer and spirally
twisted at the tips of the branches, 5-9 mm. long, lanceolate-lin¬
ear, from a broader yellow or brown base, margins finely serrate
above, vein ending in the channelled apex; lower cells elongated,
porose ; upper, shorter with thick protruding walls. Dioecious ?
Seta twisted or arcuate, 5 mm. long, stout ; capsule almost globose,
2 mm. long, walls smooth and thick, brown and shining; lid conic-
beaked ; peristome double, outer, a thick fleshy membrane ; inner,
short, fragile, with bright yellow smooth teeth ; calyptra, not seen ;
spores large, .0810-.0864 mm.

This is one of the handsomest species collected by Dr. Rusby
and was dedicated to him by Dr. Muller, but referred to a new
genus allied to Leptodontium ; but after careful comparison
at Kew with specimens of Macromitrium trichophyllum Mitt.,
and M. scoparium Mitt., I have concluded that its alliance is with
these species. The absence of the calyptra is unfortunate, but in
all other respects the likeness is very close, and the alliance is
concurred in by William Mitten, to whom specimens were sent.

488 ( 21 )

Schlottheimia Rusbyana C. Muller, n. sp. Near Yungas, 4600

ft. 1883(3191).

Plants densely matted together in dark red-brown cushions
among the roots of orchids. Stems trailing, branches erect, about
1 cm. long ; leaves densely crowded at the apex of the branches,
erect-appressed and plicate when dry, 1-1.5 mm. long, oblong,
obtuse, the vein ending in a short cuspidate apex ; upper cells in
regular transverse rows, the blade slightly undulate ; lower elon¬
gated with thickened papillose ends. Plants sterile ; alliance not
determined.

Zygodon recurvifolius Sch. Sorata, Bolivia, 8000 ft. Feb.,
1886 (3I94-)

Compared with type in Herb. Schimper at Kew, no. 1629, G.
Mandon Plantae Andium Boliviensium Exsicc. from Vicinius Sor¬
ata; also compared with no. 1627 Z. fenugineus Sch., of the same
Exsiccatae, Dr. Muller having determined Dr. Rusby’s- specimen
as the last named species. It is unmistakably the former having
much larger leaves which quickly become recurved when moist¬
ened. The plants also are not at all rusty. M. Bescherelle has
subsequently supplied me with duplicates of Mandon’s nos. 1629
and 2627 and I have recently been able to verify my previous de¬
termination.

Entosthodon papillosum E. G. Britton, n. sp. Sorata 10000 ft.
Feb. 1886 (3131).

Plants scattered on hard, bare patches of earth; plants includ¬
ing the sporophyte 5-8 mm. high ; leaves few, rosulate, long subu¬
late, acuminate, the vein excurrent into or ending below the long
slender tip, margins entire ; cells very lax. Dioecious. Seta 5-8
mm. long, stout, densely papillose, erect or slightly arcuate when
dry, sinuous when moist; capsule globose-pyriform, about 2 mm.
long, including the stomatose neck ; lid flat ; peristome none ;
calyptra not lobed at base.

Allied to E. Lindigii Hpe. according to the description and
key given by Mitten (Musci, Austro-Americani, p. 243), but differ¬
ing in the densely papillose pedicel. This and the following
species were found growing together in the same patches.

Entosthodon Lindigii Hpe.? (ex. descriptio.) Sorata 10000 ft.
Feb. 1886 (3131).

Compared with specimens of E. Mandoni Sch. mss., no. 1645,
Mandon, Bolivia, the leaves of which are less acuminate and
have not a subulate tip ; in both, the leaves are not bordered and

(22)

484

the mouth is small and surrounded by 3-4 rows of darker, denser
cells. In E. apiculatus Sch., no. 1646 of Mandon, the lid of the
capsule is beaked, not flattened as in our specimens , and the leaves
are not subulate pointed.

Funaria hygrometrica (L.) Sibth. Near Yungas, 4000 ft., 1885
(3132a).

Growing mixed with Brymn argenteum var. lanatum .

Funaria calvescens Schwaegr. Near Yungas, 4000-6000 ft.,
1885 (3133a); Unduavi, 8000 ft., Oct., 1885 (3133b).

Funaria incurvifolia C. Muller, n. sp. Near La Paz, 10000 ft.,
Oct., 1885 (3132).

Plants 1-2 cm., pale straw-yellow; stems often several together,
2-5 mm. high; leaves rosulate, 2-2.5 mm. long, incurved, carinate-
cucullate ; vein yellow, ending in the acuminate, incurved apex ;
margins with a narrow border of 1 row of elongated cells, entire
or faintly subserrulate ; cells of the basal angles large, swollen.
Dioecious; seta 5-10 mm. long, pale yellow and twisted; capsule
small, 1.5-2 mm., oblique-pyriform; annulus large, compound,
falling with the blunt lid; teeth with projecting cross-bars; inner
peristome present, of short slender segments.

Belonging to the section of F. hygrometrica with which it was
compared; differs in being smaller with incurved, more hyaline
leaves, the cells with thinner walls.

Both F. hygrometricoides Sch. (Mandon, no. 1648) and F.
Mandoni Sch. (Mandon, no. 1647) have shorter, blunt leaves,
with cells more lax and thicker walled, and the vein ending
below the apex with the marginal cells more swollen.

Philonotis asperrima C.M., n. sp. Sorata, 10000 ft. (3140).

Plants small; stems matted with brown tomentum, branches
short, less than 5 mm. long, numerous ; leaves of two kinds, those
of the main stems with a long subulate tip, a dark excurrent vein
and serrate, revolute margins, with clear, rectangular cells ; branch
leaves smaller, the upper part of the leaf very spinose, the vein
ending in the shorter, acuminate apex, margins plane or slightly
recurved, sharply serrate ; lower cells quadrate, smoother and
clearer than in the upper ones. Dioecious. Perichetical leaves,
broad, hyaline, and clasping at base, with a long subulate apex.
Pedicels short, 1 cm. ; capsules globose, 1.5-2 mm., oblique, strongly
ribbed ; lid mamillate, appressed ; peristome double, endostome
shorter than the teeth, mouth bordered by 4-6 rows of darker
denser cells.

Growing mixed with Bryum argenteum var. lanatum and a

485

(23)

sterile species of Dicranum in dense tufts, copiously fruiting.
Compared with nos. n, 13, 14, 17, 18, 20 and 21 of the species
listed by Mitten in his Musci Austro-Americani. Most closely
related to P. gracilenta Hpe., but differing in its smaller size and
shorter pedicel.

Philonotis pagionifolia C. M., n. sp. Yungas, 4000-6000 ft

1885(3139)*

Plants forming dense, matted tufts, with little fruit ; stems
short, branches fasciculate, about 5 mm. long, slender and curved
at apex; leaves erect-spreading or secund, narrowly lanceolate,
acuminate from a clasping, slightly decurrent base ; margins
thickened or revolute with several rows of teeth from base to
apex ; vein thick, excurrent into a toothed subulate apex ; cells
clear and square at base, all papillose on the upper surface. Dioe¬
cious ; perigonium broad and clear at base, long-cuspidate at
apex ; perichetium concave, hyaline at base, ecostate, also with a
long serrate tip ; both sets of bracts much longer than the stem
leaves. Pedicels 20-25 mm. long, bright glossy, orange-colored ;
capsule 3 mm. long, oblique, strongly ribbed when dry ; lid mam-
illate ; peristome double.

Resembling P. gracilenta Hpe. (Lindig, New Granada) but the
leaves are more blunt. Compared with Mand'on’s no. 1676 from
Sorata, Bolivia, named by Schimper Philonotis Bolivianay it differs
in its slender and delicate branches, which are less fasciculate.
Specimens at Kew are much confused in this troublesome group
of species, but ours do not seem to agree with any of theirs. The
nearest are those collected by Matthews at Casapi, Peru, in Herb.
Hooker, named by Wilson and labelled “No. 2313, Bartramia un-
cinata” (B. scabrida Schwaegr. Supp.//. 57), but they differ in the
leaves being non-cuspidate and in the large ecostate perichetium.
Bartramia (plicatella) scorpioides C. Muller, n. sp. Near

Yungas, 4000 ft., 1885 (3138).

Plants large, 5-6 cm. high, decumbent and matted with brown
tomentumatbase, yellowish-green, glossy; stems arcuate, branching
by innovations 1-2 cm. long, or fasciculate; leaves secund, uncin¬
ate, acuminate, plicate ; vein narrow, ending in the carinate serru¬
late apex, forming a sharp point; cells all papillose, the end walls
thickened; dioecious; the antheridia surrounded by broad orange-
colored bracts, with serrate papillose tips ; perichetial leaves broad,
clasping and hyaline, smooth and entire, vein narrow, excurrent
into a slender point ; pedicels 10-15 mm. long, red, curved at tip;
capsules all eaten off or decayed.

Resembling B. andina Mitt, in its secund leaves, but when
compared with Spruce no. 429 from Pichincha they are quite dis-
tinct, our species belonging to the section with B. arcuata and B .
scopcnia , but agreeing with neither. The absence of fruit prevents
the determination of its closest alliance.

ous, white, clasping imbricate base, those of the young branches
with a slender twisted apex 3-5 mm. long ; older ones all broken
off, the white base smooth, the upper part opaque and papillose
on the short walls of the cells ; margins bordered by 1 row of
long yellow cells with small appressed teeth ; vein narrow, toothed
on back. Dioecious. Perichetiai leaves with a short base and
long serrate awn. Pedicel curved, 5 mm. long, red ; capsule
curved, 2 mm. long, with a small orange-colored lid ; mouth
small ; walls ribbed ; peristome short, double.

Allied to B. potosica Mont., but differing in the longer, less
crowded, more spreading leaves with a more conspicuous white
clasping base. Named by Dr. Muller for Dr. Rusby but Schim-
per’s name has priority.

Bartramia (Vaginella) auricola C. M. n. sp. Ingenio del Oro,

10000 ft., February, 1886 (3135b). Sorata, toooo ft., Feb¬
ruary, 1886 (3135a).

Plants light green or brown when old, with numerous, erect,

487

(25)

simple stems, 1-2 cm. long, matted together with brown tomen-
tum at base; leaves 2-6 mm. long, crowded, their white bases im¬
bricated, the green upper part of the blade spreading, much
broken, except on the youngest branches; margins finely and
sharply serrate, bordered by one or two rows of smooth, elon¬
gated, clear cells, those of the blade densely papillose and opaque,
vein narrow, keeled and spinose on back. Dioecious, perichetial
leaf with a short basal blade only covering the foot and a long
rough awn; pedicels short, 3-5 mm. long, pseudo-lateral, straight
or curved ; capsules large, 3 mm., erect or oblique, strongly ribbed
when dry and brown; lid mamillate, appressed; peristome double,
teeth, orange-red, trabeculate on the inner face; spores large, .027-
.032 mm., rough, brown.

Differing from B. thrausta in its smaller size, more strict, erect
habit, stouter more rigid leaves. Agrees with Lechler’s no. 2680,
from Chili, labelled B. potosica at Kew, but differs from the type of
that species at Paris in the much more conspicuous white base of
the leaves.

Bryum Rusbyanum C. Muller, n. sp. Yungas. 6000 ft. 1885

(3148a).

Plants slender, stems erect with short, strict branches, bearing
small, erect, lanceolate, serrate leaves, vein disappearing below the
apex; stem leaves larger, acuminate with a prominent red vein,
also disappearing below the apex. Dioecious ; pedicel, 3 cm.
long, tawny , capsule pendent, 3-4 mm. long, with a neck half its
length; lid mamillate; annulus double, inflated, dehiscent in frag¬
ments; mouth with an orange-colored border ; cell-walls of exothe-
cium much thickened, peristome double, teeth white, granulose,
erose and irregular, endostome also granular with a basal mem¬
brane, segments hardly distinguishable from the teeth, neither
carinate nor parted, basal rudiments of cilia two ; spores large,
yellow.

Seemingly a Dicranobryum most nearly allied to D . fusifemm ,
Mitt, with the type of which it was compared at South Kensing¬
ton. Nat. Hist. Museum.

Bryum ( Webern ) albicans (Wahlb). Near Valparaiso, Chili,
June, 1885 (3145). Antheridial plants only. Sorata, Bolivia,
10000 ft. February, 1896 (3193). Sterile.

Compared with Austin’s, No. 189, Musci Appalachiani, these
specimens agree perfectly in all the leaf characters, but are a little
taller, 3-4 cm. in height.

Bryum humillimum C.M., n. sp. Ingenio del Oro, 10000 ft.
March, 1886 (3147).

Plants small, bright glossy, yellowish-green ; with julaceous
branches less than 1 cm. high ; stems red; leaves small, 1 mm.
or less, imbricate, concave, those of the young branches obtuse
and closely imbricated, the vein dividing and ending below the
apex ; lower cells lax and enlarged, upper rhomboidal spindle-
shaped, forming small inconspicuous teeth. Dioecious. Pedicels
short, 5-7 mm. long, darker below ; capsules 2 mm. long, pen¬
dant ; neck nearly half the length, contracted below the spore-
sac; lid mamillate, orange-colored, rim red; annulus large, falling
with the lid ; peristome double, outer of light yellow teeht, papil¬
lose outside, trabeculate inside; endostome a shorter membrane
with carinate segments, open along the keel, with rudiments of
two cilia between.

Closely allied to Bryum julaceum Sm.,but differing from Euro¬
pean specimens at Kew in the shorter more rigid branches, with
more closely imbricated leaves and shorter pedicels. Specimens
collected by Mandon near Guyaboya, 28th May, 1866, named
B . julaceum, at Kew, differ in much longer, more slender branches
and pedicels 10-12 mm. long.

Bryum soboliferum Taylor. Sorata, 10000 ft. February, 1886.

Compared at Kew with specimens collected by Jameson from
Quito, nos. 1 5 1-200, and Pichincha, no. 328. Sent to Dr. Muller
and with this name, and he replied “ forsan species nova.”

Bryum coloratum, C. Muller, n. sp. Near La Paz. October,
1885 (3140-

Plants cespitose, in loose light-green cushions; stems with
several 4-5 short fasciculate innovations about 1 cm. high ; leaves
in rosettes at the ends of the branches, 2-6 mm. long, oblong-
lanceolate carinate, serrate above the middle, margins bordered by
2-3 rows of elongated cells ; vein round, ending in a short mu-
cronate apex ; cells all regularly rhomboidal. Dioecious. Peri-

double perfect, teeth brown, inner membrane deep, carinate seg¬
ments open along the keel with 3-4 slender, papillose, appendicu-
late cilia; spores brown .013-.016 mm.

Resembling B. cernuum Hedw. in the bright yellow color of its
capsules, but a larger and coarser plant, seemingly one of the
smaller Rhodobryums , with the leaves twisted when dry, allied to
B. andicola.

Mielichhoferia campylocarpa H. & T. Near Yungas, 4000 ft.

(3149).

Mielichhoferia n. sp. ? Ingenio del Oro, 10000 ft. March,

1886 (3146).

These specimens were compared at Kew with all the species
described by Mitten (Jour. Linn. Soe. 12, 320) having leaves at
all similar and found to be most nearly related to M. diplodonta,
but as the fruit is too immature to determine any peristome char¬
acters, it cannot be safely referred to any of them. A portion
sent to C. Muller was named by him Mielichhoferia modesta n. sp.

Plants dark red, glossy; stems erect, unbranched 5-6 cm. high,
leaves erect, 5 mm. long, closely imbricate with a brown clasping
base; margin coarsely serrate; vein pellucid, excurrent into a
smooth blunt cusp ; perichaetium longer tipped, enclosing long dark
protruding paraphyses ; Dioecious, the male plants proliferous at
apex. Pedicels stout, erect, 2-3 cm. long, bright fulvous, capsules
horizontal 4-5 mm. long ; lid conic, beak hooked, 2 mm. long.

POLYTRICHADELPHUS INTEGRIFOL1US C.M., n. Sp. Unduavi, IOOOO

ft. October, 1885 (3159a).

Stems 5-8 cm. high, leafless below and tomentose, proliferous
at apex; leaves erect, slightly spreading, vein broad, excurrent
into a smooth, dark awn; margins entire, incurved; lamellae
seven, rows of cells high, uppermost cells rounded in section.
Dioecious. Perigonial bracts scarious, with short triangular
points.

Male plants only collected, and from the robust stems and
broad, scarious, perigonial bracts it strongly resembles Polytri -
chum. Compared with various species of Polytrichadelphus at
Kew, none of which it resembles.

Plants 5-8 cm. high; stems naked below, densely leafy above;
leaves erect-appressed, almost imbricate when dry, 5 mm. long,
margins serrate with a few large, coarse, teeth; lamellae filling
almost all of the blade, margins only slightly incurved. Periche-
tial leaves longer, erect, innermost with a scarious base and long,
slender tips; pedicel 15-25 mm. long; capsules 3 mm. long with
a small hypophysis; teeth lax, short, pale and regular.

No specimens bearing this name can be found in Schimper’s
Herbarium at Kew.

Polytrichum aristiflorum Mitt. Unduavi, 8000 ft. October
1885 (3;55a).

This species has also been collected at Yungas by Pearce
There are a great many diverse localities cited for this species by
Mitten, and there is as much diversity in the specimens at Kew.
We referred all of Dr. Rusby’s specimens from Yungas, nos. 3155b
and c and no. 3155a from Sorata and 3155c from Mapiri to this
species, but Dr. Muller gave it a manuscript name, which is ante¬
dated by P. patulum Harvey (MU11. Syn. Muse. 1 : 210) from Ne-
paul. It seems probable that there is room for the separation of
several species, but as ours agree with Jameson’s from the Andes

491 (28a)

of Quito and Weddell’s from Peru, vve have thought it best to
enumerate them under this species.

Polytrichum angusticaule C.M., n. sp. Near Yungas, 4000 ft.,
1885 (3155).

Plants large, 8-10 cm. high; stems simple, 2-4 cm. high; leaves
6-8 mm. long, the clasping base oblong, brown or slightly scari-
ous on the margins, tapering into a slightly longer apex, with in¬
curved entire margins; vein rough on back, with two or three
rows of sharp teeth, excurrent into a smooth or only slightly rough¬
ened awn ; lamellae covering almost all of the blade, of 6-7 rows
of cells, the last row elongated, conical and smooth. Dioecious ;
male plants proliferous ; perichetial leaves with a long smooth
point; seta 6-8 cm. long, stout, glossy, curved at apex ; capsules
large, 5 mm. long, cubic, with a short wrinkled apophysis ; lid
dark red, beak long; teeth white, 64.

Closely allied to P. aristiflorum Mitt., and compared with speci¬
mens sent us by Wm. Mitten, collected in Venezuela by Funk and
Schlim, no. 472. Differs in the longer, scarcely roughened awn of
the leaves, which are more closely appressed when dry, and in the
larger capsules.

PLEUROCARPI.

All the specimens of the pleurocarpous mosses as well as the
acrocarpous ones were carefully studied and separated before du¬
plicates were sent to Dr. Muller, yet in two cases in the genus
Hookeria, there was evidently a mixture of species growing to¬
gether, which in one instance seems to have misled Dr. Muller.
Hookeria Bakeri E. G. Britton, n. sp. Near Yungas, 4000 ft.
1885 (3163).

Plants yellowish-green, large and coarse; stems 2-3 cm. long;
branches 1 cm., leaves curled and crisped when dry, more or less
undulate with long subulate tips 2 mm. long, veins prominent
when dry, ending just inside the margin, which is entire below,
serrulate along the tapering apex and bordered by 3 rows of nar¬
row, elongated cells; those of the blade very large and clear, not
papillose. Pedicel 20-25 mm. long, bright, glossy brown; cap¬
sules ovoid, 2 mm., brown, walls thick; lid conic-rostrate; teeth
long, slender, brown and incurved in pairs, and papillose ; endo-
stome yellow, erect, carinate segments closed.

Compared with H. marginata to which it is related, but differs
in the lighter green leaves, broader and less acuminate, the cells
more lax and hyaline.

Dedicated to Mr. J, G. Baker, of the Royal Herbarium at Kew,
in grateful acknowledgement of the many kind favors received
from him while at work, under his charge, on Dr. Rusby’s Ferns
and Mosses, and also as a small recognition of the task he accom¬
plished in mounting and putting in order the Herbarium of W. P.
Schimper, presented to Kew by the Baroness Burdett-Coutts.

This species was first named H. castanea, from the description
only, and when submitted to Dr. Muller he discovered three new
species in it; but as we can find but one specimen in our packet,
and have no means of determining which of his names apply to
our species, we have discarded all his manuscript names.
Hookeria purpureophylla C.M., n. sp. Near Yungas, 6000 ft.
1885 (3164).

Plants small, light reddish brown, .7-1.5 cm. high; stems
branched, distichous, or flattened; leaves small, 1 mm. long,
closely imbricate, appressed with flexuous, filiform spreading
points ; veins ending below the rounded part of apex, toothed at
the back of the leaf above ; margins serrate to below the middle,
more coarsely so above ; cells papillose, upper wine-color, lower
colorless and longer; pedicel purple, 15 mm. long, arched at
apex; capsule 2 mm. long; neck tapering; lid conic- rostrate.
Peristome not yet matured, torn off with lid.

Compared with H. (Callicostella) rufescens Mitt. (Spruce, no.
629) from which it differs in the longer acuminate leaves ; they
also are more slender and not so crisped as those of H. purpurea
and are too acute for H incurva. Our plants are mixed with a
small, golden yellow Hypnum in fruit, and a brown Hepatic, but
we cannot find the two species of Hookeria , indicated by Dr. Muller
in his letter by two other manuscript names.

uous white hairs, ovate and quite concave in the middle with a
plane border of small square cells in straight rows, and the mar¬
gins double or recurved, bluntly papillose, frequently brown
in the upper half with elongated cells in the centre of the base, and
others sinuous ; apex serrulate or erose when long and hyaline ;
perichetium short, 3 mm., enclosing very long paraphyses, bracts
strongly plicate, cells long and clear, apex not hyaline ; pedicels
1 cm. long, capsules about 3 mm. with small orange-colored
mouth and apiculate lid.

Braunia subplicata E. G. Britton, n. sp. Ingenio del Oro, 10000
ft., May, 1886 (3154); Mapiri, 5000 ft (3154a).

Plants dark brownish green, in large dense mats, stems de¬
cumbent, pinnately branched, often giving off radiculose stolons,
branches erect, 4-5 cm. long ; leaves subsecund when moist, im¬
bricate and erect when dry, with three blunt ridges, not hyaline
pointed, ovate-concave, over I mm. long, less than 1 mm. broad,
with entire revolute margins and a conspicuously rolled border to
the concave center, apex acute and concave, erose dentate, but not
hyaline, conspicuously papillose at the tips of the branches, basal
cells elongated brown, others regular and sinuous ; perichetium
narrowly lanceolate, erect, sulcate, 3 mm. long, with oblong yellow
cells at base and middle and blunt erose tips; pedicels 1 cm. long,
erect or cernuous twisted, fulvous as well as the base of the cap¬
sule, which is 2 mm. long with a straight beak over I mm. long,
mouth with a thick red rim, calyptra brown, 3 mm. long, tufted
and ragged at base with a straight beak 1 mm. long.

Differs from H. plicata Mitt. (Bridges, Bolivia in Herb. Hooker)
in the dull brown color of the plants and in the leaves not being hy¬
aline tipped ; from H. secunda (Hook. Musci Exot. t. 46, Humboldt’s
type in Herb. Hooker) in the larger, less secund leaves with more
strongly revolute margins ; resembling only an unnamed scrap in
Herb. Hooker, collected by Mathews in Peru at Casapi, and a
part of Braunia subsecunda Sch. M. S., no. 5, in Herb. Schimper
without locality or name of collecter. (See Jaeger, p. 86) pencilled

Compared with G. Mandon Plantae Andeum Boliviensium
Exsicc., no., 1638 vicinius Sorata, labelled Harrisonia rhabdoccupa
Hpe. with which it agrees. As also with Lindig’s New Granada,
no. 2000. Both of these are considered to be H. imberbe Sm.
(Mitt. J. L. Soc. 12: 405). The plants mixed with 3154a are
coarser and brighter green, agreeing better with Spruce Musci
Am. et. And., nos. 1293-1295, of H. imberbe . There is consider¬
able variation in the size and color of this species, also in the de¬
gree of ramification of the stems and the appression of the leaves,
but otherwise the leaves are indistinguishable when placed side by
side under the same cover-glass under the microscope. Wed¬
dell’s no. 9 Peru, are small, little over 1 cm. high and almost sim¬
ple like 3152 H. H. R., while Spruce no. 1295 and Rusby’s 3154a
are nearly 6 cm. high and quite pinnately branched.

Plants large, slender; stems bipinnate, 10-15 cm. long,
branches pendant, 5-6 cm. long, branchlets few and distant,
I— 1.5 cm. long; leaves spreading when dry, those of the
branches 2 mm. long, those of the branchlets only about I
mm. long, both lanceolate-acuminate, vein ending below the
long subulate, serrate apex, margins entire below, slightly
recurved in the middle; basal angles auricled, decurrent. Cap¬
sules two or three together at intervals along the branches,
perichetial leaves with a broad, clasping base covering the capsule,
vein scarcely extending below the long nearly smooth awn,
exceeding the base in length. Capsules 2 mm. long ; peristome
double, the outer of long, spreading, broad teeth, the inner of
shorter, narrower segments, composed of a double row of papil¬
lose cells, attached to a basal membrane.

Allied to C. pilifera Mitt., and possibly referable to that spe¬
cies, but recognized also by Muller as a new species, Schimper’s
name having priority.

Plants sterile. Allied to M. patulum Sw.

Meteorium filiferum (C.M.) Mitt. Near Yungas, 4000 ft. 1885.

(3173).

Plants dark green or black with lighter yellowish branches.
Youngest shoots very slender, filform, and totally different in as¬
pect from the older stems ; stem leaves, entire, concave, the vein
ending below the short recurved cuspidate point; basal angles con¬
spicuously inflated at the inner angle, with a small round group
of yellow cells ; leaves of the young branchlets much smaller,
distant, narrowly lanceolate-acuminate, vein ending below the long
filiform point ; basal angles decurrent with the same conspicuous
round auricle, at the inner point of insertion.

Named from description, and compared with No. 131 col¬
lected by Weir, Andes Bogotensis from which it differs in aspect,
and the presence of the long filiform branches described in the
original.

Meteorium (Pilotrichella) perinflata C.M. n. sp. Near Yun¬

yellow, endostome as long, carinate segments rarely open along
the keel; spores green, .021-.024 mm.

Allied to M. crinitum Sulk, but differing in the entire leaves
and the long peristome, the inner not adhering to the outer
Specimens not compared.

Meteorium (Pilotrichella) reflecto-mucronata C. M. n. sp

Sorata, 10000 ft., February, 1886 (3170).

Plants light green, glossy ; stems creeping and rooting ; branches

Plants light yellowish-green, with a creeping rhizome ; stems
4-5 cm. long, naked below, about 2 cm., bipinnate ; branches flat¬
tened, frond-like, red; leaves compressed, elliptical-oblong, unequal
at base, about I mm. long ; vein dividing and disappearing below
the broad sharply serrate apex ; margins entire below ; cells of the
basal angles only slightly differentiated ; monoecious ; antheridial
buds on different branches from the archegonia ; perichetial leaves
longer, outer squarrose, subulate, often veinless, inner erect-clasp¬
ing, with a narrow vein ; seta red, flexuous, 10-15 mm. long; cap¬
sule 2 mm., ovoid-cylindric, neck short; lid 2 mm. long, with a
ong beak ; annulus large, simple ; peristome double, teeth long,
slender, endostome of slender papillose carinate segments, open
along the keel; cilia none.

Allied to Porotrichum longirostrum (Hook.) Mitt, and possibly
referable to this variable species, according to Mitten. Compared
at Kew with specimens collected by Spruce (And. Quit. nos.
1 361-1 363) from which ours differ in being much coarser, with less
slender, not flagellate branches and shorter stouter pedicels,

497

(28g)

agreeing better with Weddell’s no. 53 from the Andes of Peru, but
our plants are smaller with shorter leaves, turning yellower with
age, and more coarsely and doubly serrate at the apex.

ous short branches 3-5 mm. long ; leaves crowded, spreading
minute, ovate-acuminate with a long subulate point, margins
spinose-dentate or rarely entire at the apex of the branches, vein
ending above the middle ; basal cells square at the angles. Peri-
chetial leaves broad and serrate at apex, with a suddenly subulate
point ; vein short. Pedicel erect, 5 mm. long ; capsule small, little
over 1 mm. long, ovoid; neck distinct, tapering into the pedicel ;
lid conic-rostrate, small, yellow ; mouth small, bordered by 4-5
rows of transversely elongated, darker, denser cells ; peristome
short, teeth brown when old, pale when young, united in fours or
divided when old, smooth, slender at apex.

Closely related to F. polycarpa Hook, from which it differs in
its abruptly subulate perichetial leaves and its ovate capsule.

Hypnum (Cupressina) “entodonticarpum C.M., n. sp. Unduavi,

12000 ft. October, 1885 (3186).

Plants in dense, yellowish-green, glossy cushions ; stems pin-
nately branched, arcuate, 1-2 cm. long, branches 5-8 mm. long;
leaves crowded, uncinate hooked, entire, veinless ; cells of basal
angles inflated, yellow. Monoecious. Perichetial leaves longer,
outer uncinate, inner erect, subulate, all veinless. Pedicels red
below, twisted above, 15-20 mm. long; capsules erect, cylindric
or arched; neck tapering; wails thin; mouth bordered by denser,
brown cells; peristome double; teeth brown, short and thick,
bordered by the adherent segments of the inner peristome.

Compared with Drepanium hamatum Mitt., no. 1046, Spruce
Musci Am. et And.), specimens of which are preserved at Kew
but are not listed by Mitten. Closely related to this species, but
differs in its more clearly veined leaves and longer pedicels.

Leskea aciculata Taylor. Near Yungas, 6000 ft. 1885 (3177).

Compared with Jameson’s specimens from Quito with which
it *agrees.

Leskea (Schwetschkea) Boliviana C.M., n. sp. Mapiri, 10000

creeping, with short, irregular branches 5-8 mm. long; leaves im¬
bricate with spreading points, ovate-acuminate, less than 1 mm.
long; margins entire; vein ending below the apex; cells rhom-
boidal above, transversely elongated below, not papillose ; monoe¬
cious ; perichetial leaves longer, erect, base long, clasping, vein
ending below the acuminate apex; cells elongated; pedicels red,
10-15 mm. long; capsule cylindric, 2 mm.; lid conic; annulus
falling in fragments, narrow, single ; mouth bordered by darker,
denser cells, walls thin ; peristome double, teeth long, slender,
papillose at apex; endostome with a short basal membrane and
slender, carinate, papillose segments, thickened at the joints, or
appendiculate ; cilia none.

Allied to L . gracillima Tayl., which has also been collected in
Bolivia by Bridges, but differs in the vein ending below the apex
and the leaves being quite smooth. Identical with no. 3185 cited
above, which was also sent to Dr. Muller and named by him
Psendoleskea amblystegiella n. sp., but this name is too near P
amblystegioides C.M. from Costa Rica, Polanowsky.

larly pinnate; branches .5-1.5 mm. long, slender; paraphyllia
small, clustered, branching; leaves small, less than 1 mm.,
crowded, minute; base concave appressed, apex subulate, serru¬
late; vein thick, channelled, excurrent; cells rhomboidal, pa¬
pillose, those of the basal angles erect, rectangular and denser on
each side of the basal folds. Perichetial leaves longer and more
acuminate, and not papillose, outer recurved, inner sheathing, all
pale and plicate with the vein ending below the apex. Pedicels
straw-colored, 2 cm. long ; capsules arched, 3 mm. long, slightly
contracted below the mouth when dry ; lid mammillate ; mouth
bordered by a deep flaring rim ; peristome inserted below the
rim, double ; teeth yellow, trabeculate ; endostome yellow, seg¬
ments as long as the teeth, carinate, rarely divided or open along
the keel, attached to a short, basal membrane, appendaged at the
joints; cilia none; spores rough, .016-.021 mm. green.

No. 3181 was named for Dr. Rusby, by C. Muller, but Schim-
per’s name has priority.

Thuidium Peruvianum Mitt. Near Yungas, 6000 ft. (3178),
Unduavi, 8000-10,000 ft. October, 1885 (3179).

(28i)

Compared with Jameson’s specimens from Pichincha and
Pearce’s from the Andes, duplicates of which have been sent to us
from Kew. The specimens collected by Miguel Bang (No. 482)
at Yungas, and listed by Dr. Rusby (Mem. Torr. Club, 2 : No. 3,
p. 274) as Thuxidium delicatulum, were so named by Mr. C. H.
Wright at Kew. Duplicates of all our specimens, including these,
were submitted to Dr. George N. Best for critical comparison.
He says : “ They apparently belong to one and the same species.

The stem leaves differ from those of T delicatulum in not being
closely appressed when dry ; they are more concave, broader at
base and more abruptly acuminate, somewhat undulate and ru¬
gose above, and the leaf-cells are more rectangular and less rhom-
boidal. Notwithstanding these differences, which indicate a vari¬
ety rather than a distinct species, the general type remains well
marked. I should refer your specimens to T. delicatulum!' But as
these specimens are much larger and coarser than any of 7. deli¬
catulum which we have ever seen, and they seem worthy of a
distinctive name, we have maintained them as above listed.

squamosis; frondibus anguste-linearis, coriaceis, apice et basi
longe acuminatis, margine glabris, revolutis, subtus densissime
squamosis ; squamis ovatis-lanceolatis, reticulatis, ciliatis ;
stipes teretes, squamosi, prope basim articulati.

Climbing on trees ; rhizome slender, less than I cm.
in diameter, covered with dark-brown, glossy, stiff, lan¬
ceolate scales ; stipes clustered, terete, arising from lateral
buds, 2 to 3 cm. long, and also covered with short, dark
scales, when old of a bright reddish straw-color, showing
a well marked joint less than I cm. from the rhizome; fronds
coriaceous, 30-40 cm. long, 2 to 5 mm. wide, broadest above
the middle and tapering to each end, of a light green color
when young, becoming tawny and mottled with black on the
upper surface when old, densely covered beneath with ovate-
lanceolate, ciliate and reticulate scales, naked above except
along the midvein; scales of the lower surface of the midvein
mottled with black ; margins nearly naked and strongly
revolute, even when boiled ; veins pinnate, about 1 mm.
apart, sometimes bifurcate near the midvein. Yungas (342),
sterile specimens only; collected also by R. Pearce, June,
1865, at Quichara, Herb. Kew, marked “epiphytal ferns.”
Another specimen, collected by Pearce at the same time and
place, has fronds nearly twice as long and broad, and the
scales are round and more deeply laciniate — perhaps a different
species. A remarkable species of the section Elaphoglossum
not approaching any member of the group that we have seen;
its nearest alliance is with A. lepidotum , Willd., and probably
with var. vittatum , Sodiro, Recens. Crypt. Vase. Quitenses,
p. 81. Named in honor of Professor Daniel Cady Eaton, of
Yale University, who first declared it to be a new species.

This species, if correctly referred to the present genus, differs
from all the others I have been able to examine in having
the separate fruits connate to very near their beaks, forming
a very dense head.

It also diverges from most of the species, in being entirely
destitute of lepidote trichomes. The leaves are about 8 inches
long by 2 inches wide, and are markedly acuminate.

LOASEHL

Loasa CANARINOIDES (Leune et C. Koch) ( Illiaria canarinoides
Leune et C. Koch, Flore des Serres t 913). This very beau¬
tiful vine, supposed by M. Planchon to have been introduced
to German gardens from Central America, was found by Dr.
Rusby in considerable quantities on the slopes of the Andes
near Unduavi, Bolivia, at an altitude of 8,000 feet. His speci¬
mens differ slightly from the type of t. 5022 of Bot. Mag., in
having blunter petals. Unfortunately all the specimens yet
