THE MOSSES OF ALASKA

The following paper on the Mosses of Alaska, by J. Cardot and I.
Thériot, was originally published in the Proceedings of the Washing-
ton Academy of Sciences, vol. Iv, pp. 293-372, July 31, 1902. It is
here reprinted from the same electrotype plates, so that it may be
quoted exactly as if it were the original. The original pagination has
been preserved and transferred to the inner or hinge side of the page,
where it is enclosed in brackets, thus [294]; while the consecutive
pagination of the present volume has been added in the usual place.
In the plates the original numbers and running headline, slightly
abbreviated, have been preserved [in brackets], while the volume
designation and serial plate numbers have been added in the usual
place. The original text references to the plates are unchanged. The
present headpiece and title have been substituted for the running head-
ing of the Academy’s Proceedings and the original title, which was:
Papers from the Harriman Alaska Expedition. xxix. The
Mosses of Alaska. No other alterations have been made.

The authors desire to record the following corrections :

THE MOSSES OF ALASKA

BY J. CARDOT AND I. THERIOT

INTRODUCTION

Tue following catalogue of the mosses of Alaska and some
adjacent islands is based primarily upon the collection made by
the Harriman Expedition in 1899. For completeness, how-
ever, species previously reported from the region are also
included.

The whole number here enumerated is 280, of which 124 are
new to Alaska and 46 are new to science. The 29 new species
and 17 new varieties, except for three species of Bryum, are
here first described.

The mosses brought back by the Harriman Expedition were
collected’ by Wm. H:. Brewer, W- R: Coe, LJ. Cole; F. V.
Coville, T. H. Kearney, De Alton Saunders and Wm. Trelease.

Previous collections were made by W. H. Dall, 1867 ; Krause
brothers, 1882; W. G. Wright, 1891; Jas. M. Macoun, 1891-

2; B. W. Evermann, 1892; C. H. Townsend, 1893-95 (Exp.
of U.S. S. Albatross); W. M. Canby, 1897; W. H. Evans,
1897; W. A. Setchell, 1899; F. C. Schrader, 1899.

Matthew Island (Trelease, 2153, 2154) ; Attu Island (J. M. Macoun).

Most of these specimens have the inner pericheztial bracts shortly
acuminate, which relates them to D. contermina Ren. & Card. (D.
roelit¢ Kindb.), but the alar cells are usually more distinct than on the
moss from Oregon and Idaho. Moreover, the comparison with numer-
ous specimens from different regions of Europe and North America
proves that the characters on which D. conterména has been established

[295] THE MOSSES OF ALASKA 255

are too variable and insufficient to establish a specific distinction. D.
contermina must therefore be considered as only a variety of D.
crispula, and the specimens from Alaska and the islands of Bering
Sea are nearly all intermediate between the type and this variety.

D. obliqua WKindb., which has been recorded from Alaska, is un-
known to us; but, from the description, it is probable that it, like-
wise, is only a form of D. criéspula. (Cfr. Kindberg, Notes on
Canadian Bryology, 1893, and Eur. and N. Amer. Bryinee, p. 210.)

Dicranum anderssonii Sch. Syn., ed. 1, p. 689.
From Port Wells (Trelease, 2277). New to Alaska.

258 CARDOT AND THERIOT ; [298]

This moss undoubtedly belongs to D. anxderssontd Sch. (Arctoa
anderssoniz Wich. in Flora, 1859, no. 27). Inhis second edition
of the Synopsis, Schimper reunites it to D. hyferboreum, from
which, however, it seems sufficiently distinct by its smaller, sub-
globose capsule, turbinate after the fall of the lid, very shortly pedi-
cellate and almost always surrounded and surpassed by the perichetial
leaves, and by the cells of the exothecium being smaller, with more
solid and more colored walls. According to C. Jensen (Bryo-
phyta of the Faeroes, in his Botany of the Faeroes, p. 159), the
capsule of Dicranum anderssonti should be destitute of stomates,
but in the Port Wells specimen all the capsules bear several stomates
at the base of the very short neck.

Dicranum strictum Schl. Pl. crypt. helv., cent. m1, no. 26.
From Yakutat Bay (Trelease, 2331, 2336).

Dicranum subflagellare sp. nov.
(Plcxmx figs 325°.)

A D. flagellari proximo differt defectu flagellarum, foliis erectis
subfalcatis angustioribus parum flexuosis, brevioribus (2—2.5 millim.),
acumine canaliculato non subtubuloso, marginibus dorsoque subintegro
cellulisque inferioribus angustioribus, superioribus multo minoribus.
Specimina pauca, sterilia.

From Kodiak (Trelease, 1899).

[299] THE MOSSES OF ALASKA 259

Dicranum fuscescens Turn. Muse. hib., p. 60, pl. 5, f. 1.

From Yes Bay (Gorman, 184); Juneau (Brewer and Coe, 6994,
400); Skagway (Canby, 478); Wrangell (Trelease, 2317); White
Pass, 3,000 ft. (Trelease, 2313); Farragut Bay (Trelease, 2416;
Brewer and Coe, 617); Yakutat Bay (Trelease, 1763, 2340); Point
Gustavus (Coville and Kearney, 777) ; La Perouse Glacier (Trelease,
2498); Sitka (U. S. S. Albatross, 53,55; Canby, 458, 463; Trelease,
2359); Hot Springs (Trelease, 1914); Kodiak (Trelease, 1853) 3
Douglas Island (Trelease, 1908, 2392) ; Port Wells (Trelease, 2282,
2288); Orca (Trelease, 1918, 1925, 2262; Setchell, 1213); New
Metlakatla (Coville and Kearney, 364.) ; Plover Bay, Siberia (Trelease,
1865).

The Yes Bay specimen was associated with Mntum glabrescens
Kindb. and Scapanza sp.

The Kodiak specimen (1853) is a paludal form, with entire, shorter,
erect leaves. We must point out too a sterile form, collected on Unalaska
Island by Mr. C. H. Townsend (U.S. 8. Albatross exped., 43), which
is very near D. muehlenbeckii Br. eur. var. brevifolium Lindb. The
same form was found by Trelease on Hall Island (1907). It differs from
the European plant chiefly in having its leaves less flexuous when dry.

Many authors separate D. congestum Brid. from D. fuscescens Turn.
but as it is almost impossible to find two descriptions of D. congestum
which agree, we can infer that it is one of those species which every
author understands in his own way, that is to say a very bad species;
and we deem it preferable to merely unite it with D. fuscescens.

Dicranum dipteroneuron C. Mill. in Flora, 1887, p. 221.

having a less rough subula. Décranum virginicum Aust. ( Cam-
pylopus virginicus Lesq. & Jam.) is intermediate between the Euro-
pean and Alaskan forms.

ductis, costa breviter excurrente mucronatis reteque magis opaco valde

papilloso.

262 CARDOT AND THERIOT F [302]

From St. Matthew Island (Trelease, 2151 in part).

We found only a few stems of this moss, mixed with Barbula
brachypoda Card. & Thér. and a Bryum. By the pellucid margin
of the leaves, it is nearly related to P. odbtus¢folia C. Miill. (P.
heimti arctica Lindb.), but it is easily distinguished from it by its
pointed leaves. It also closely resembles Desmatodon systyliotdes
Ren. & Card., from Labrador, which is probably also a Pottza of the
same group, but it differs from this species by its ovate, shorter and
proportionately wider capsule, its longer and more finely beaked lid,
its shorter and more briefly acuminate leaves, and finally by its areola-
tion formed of larger and less obscure cells.

According to J. M. Macoun P. hezmit typica has been recorded by Kindberg
from St. Matthew Island and from Bering Island.

Contrary to Kindberg’s description, the leaves are entire or nearly
so on the specimen we have seen. It is probable that this moss is but
a form of D. rubellus.

Trichostomum cuspidatissimum sp. nov.
(Pl. xin, fig. 4°—*.)

Dioicum, elatum, compacte cespitosum, fusco-lutescens. Caulis
erectus, circa 5 centim. altus, dense foliosus, rufo-tomentosus, ramis
erectis numerosis. Folia siccitate crispata, madore erecto-arcuata, ad
apicem caulis et ramorum congesta, fragilia (acumine sepe effracto), e
basi ovata sensim et longissime acuminata, 3-3.5 millim. longa, 0.45-
0.7 lata, marginibus planis, superne inflexis, papillis prominentibus

From Hall Island (Brewer and Coe, 674).

A fine species, easily distinguished from the large forms of 7. mata-
ble Bruch, and its var. cuspidatum Limpr. (Z. cuspidatum Sch.),

[303] THE MOSSES OF ALASKA 263

by the form of the leaves, and more particularly by its narrower costa
and its upper cells which are much larger and more distinct (10-12 »
instead of 6-8).

Trichostomum sitkanum sp. nov.
(Pl. x1v, fig. 17.)

Dioicum? Cespites densiusculi, superne virides, intus nigrescentes,
inferne terra obruti. Caulis 2-3 centim. altus, parum divisus, laxe
foliosus. Folia mollia, sicca cirrato-crispata, madore patula, inferiora
2.5-3 millim. longa, superiora majora, 4—4.5 millim. longa, e basi
longe subvaginante lineari-lanceolata, marginibus planis integris, costa
sat valida, basi circa 110 p» lata, in mucronem lutescentem breviter ex-
currente, cellulis basis subvaginantis rectangulis, hyalinis, 4-6 long.
quam lat., cateris quadrato-hexagonis, 12-14 » latis, valde papillosis.
Cetera desunt.

From Sitka (Trelease, 2370).

The aspect, the form of leaves, the looser basal areolation and the
upper cells more papillose, easily distinguish this plant from 7. cuspi-
datissimum Card. & Thér. It is more closely connected with 7.
bambergert Sch., but the latter has the costa shining on the back in

a dry state, and the hyaline cells of the base going up along the borders
of the leaf, as in Barbula tortuosa Web. & Mohr.

From St. Matthew Island (Trelease, 2151 in part, 2166).

This species, which belongs to the section Cumnezfolie Sch., is
easily distinguished from &. cunezfolia Brid. by its leaves revolute be-
low, its longer lower cells, the upper more chlorophyllose with thicker
walls, its shorter seta, its broad annulus, etc.

Kindberg has established (in Revue bryologique, 1896, p. 22)
a B. subcunetfolia from Alaska, which, by some characters, seems to
be near to our B. brachypfoda; but his description is so incomplete
that we can neither ascertain whether this B. swbcunezfolza is identi-
cal with the plant here described, nor, with still more reason, mention
the characters which might distinguish it from the former,

Barbula saundersii sp. nov.
(Pl. xvi, figs 165)

Dioica? laxiuscule cespitosa, olivaceo-viridis. Caulis brevis, 5-8
millim. altus, simplex vel parce divisus. Folia sicca incurvata, madida
erecta vel erecto-patentia, 1.5-2 millim. longa, 0.8 lata, e basi ovata
breviter acuminata, obtusa vel brevissime mucronata, marginibus e

operculo conico longissimo, capsulam zquante. Peristomium pur-
pureum, papillosum, membrana basilari brevi, 30 alta, dentibus
semel vel bis contortis. Spore leves, 14-16 crasse.

From Hidden Glacier Inlet, Yakutat Bay (Trelease, 2514).

In habit recalls the smallest forms of B. ungutculata Hedw., from
which it differs by the shorter and proportionately broader leaves, which
are shortly ovate-lanceolate, not or hardly mucronate, etc. By the form
of the leaves, it is also connected with B. drachyphylla Sulliv., but
the latter has the stems much longer and the basal areolation of the
leaves quite different.

[305 ] THE MOSSES OF ALASKA 265

Barbula treleasei sp. nov.
(Pl. xv, fig. 2*—9.)

Dioica? dense cespitosa, lutescenti-viridis. Caulis 1-2 centim.
altus, erectus, divisus. Folia siccitate crispatula, madore erecto-pa-
tentia, circa 1.5 millim. longa, 0.6 lata, ovato-lanceolata, breviter

multo longiora et latiora, sat subito constricta, longe acuminata, madore
arcuato-patula, intima subvaginantia, in dimidio inferiore hyalina.
Capsula in pedicello 10-11 millim. longo, erecta, oblongo-cylindrica.
Cetera desunt.

From Juneau (Trelease, 2179, 2181).

This moss has the aspect of a slender B. fallax Hedw.; but the
texture of the leaf base, formed of rectangular subhyaline cells, clearly
separates it. On the other hand, it differs from 2. véxeals Brid. and
allied forms by the much shorter leaves.

Barbula rigens sp. noy.
(Pl. xv, fig. 1°79.)

Rubella, laxe cespitosa vel aliis muscis gregarie intermixta. Caulis
gracilis, erectus, rigidulus, divisus, 1-2 centim. altus. Folia sicca
crispatula, madida erecto-patentia, stricta, breviter lanceolato-linearia,
1.25-1.5 millim. longa, 0.3 lata, marginibus integris medium versus
paululum revolutis, costa valida, tota fere longitudine zqualiter crassa,
diam. 56 », biconvexa, percurrente vel in mucronem brevem excurrente,
cellulis inferioribus rectangulis, hyalinis, plerumque levibus, superiori-
bus opacis, indistinctis, quadrato-rotundatis, utraque pagina dense
papillosis, mediis circa 11 y latis. Cetera ignota.

From Orca (Trelease, 2260; mixed with Déstichium capillaceum
and Anactangium compactum).

This species belongs to the group of B. rig¢dula Mitt., from which
it is easily distinguished by its stiff stem and leaves, the latter being
shorter and very briefly acuminate and by its much more papillose
areolation.

R. tenutnerve and palmert of Kindberg surely constitute but one
species, which differs from A. fasctculare Brid. principally by its
weak, flat costa, disappearing far from the point. Kindberg is mis-
taken inattributing to #. Ja/mer¢ a percurrent or subexcurrent costa.

268 CARDOT AND THERIOT : [308]

On the original specimen collected by Palmer, and which Kindberg
himself formerly communicated to us, the costa has exactly the same
length and the same structure as in A. tenuznerve. The latter is a
form with long simple or hardly branched stems, whereas PR. palmeri
is a shorter and more ramulose form.

By the shape of its capsule, dilated at the mouth, this species is very
distinct from U. druchzz Hornsch. and U. intermedia Sch. It can-
not be, either, mistaken for U. connectens Kindb., which, according
to the author, has a short, hardly emergent seta. U. camptopoda
Kindb. would appear, according to the description, nearer to U.
alaskana, but as Kindberg has recently joined it to his U. con-
mectens, we need not take it into account. Besides, he gave it the
aspect of U. crzspula Bruch, which does not at all agree with our U.
alaskana, characterized by its great size and the length of its seta.

This moss was distributed as O. axomalum Hedw., but it bears no
resemblance to that species. It is allied to O. cribrosum C. Miill.
from the Chukchi peninsula, Siberia, chiefly by the shape of the capsule
and the structure of the peristomial teeth, but it differs from it by its
larger size and the leaf-areolation, composed of less incrassate and less
papillose cells. In O. crzbrosum the leaf-cells are strongly incrassate
and coarsely papillose from the base.

From St. Paul Island (Trelease, 2067, 2074).

A remarkable species, very distinct from all the Eztosthodon of
Europe and North America by its polygamous inflorescence, its leaves
shortly spatulate, obtuse or subapiculate, and its calyptra hardly swell-
ing. It is much to be regretted that the too immature capsules do not
show the peristome, annulus and spores.

Island (Saunders, 1859; Trevor Kincaid) ; St. Matthew Island (Tre-
lease, 1894); Attu Island (J. M. Macoun); St. Paul Island (J. M.
Macoun).

A very variable plant. The numbers 1789, 1843, 1852, 1855 and
1928 of Trelease, as well as numbers 1743 and 1744 of Coville and
Kearney, are forms more or less resembling var. cesfitosa. A speci-
men gathered on Unalaska Island by Mr. J. M. Macoun is a form
remarkable by its subacute, distinctly nerved perigonial leaves, and by
its stem-leaves, which are hardly revolute on the borders and possess
a loose areolation, characters that place it near the var. cesfztosa, but
it differs from the latter by its stems provided with much more
numerous fasciculate branches. On the other hand, it is closely con-
nected with the form that Kindberg named P. acutzflora, but in
the latter the stem-leaves are strongly revolute. Number 1812 of
Trelease, as well as the specimens from Kukak Bay and St. Paul
Island, constitute a heterophyllous deformation, with upper leaves
often obtuse or subobtuse. The var. serrata Kindb. (Attu Island,
teste Macoun) does not appear to be distinguishable from the type.

Yakutat Bay (Trelease, 1819).

Philonotis capillaris Lindb. in Hedwigia, 1867, p. 40.

From Kodiak (Trelease, 1841). New to Alaska.

This sterile specimen has, it is true, the aspect, size and areolation
of the European P. capzllaris, but it differs from it by the leaves
revolute on the borders from the base for two-thirds of their length.
However, it seems impossible to ascribe it to another species.
Moreover, according to Mr. Dixon (Handbook, p. 297), P. capillarés
may have the leaves more or less revolute; this character would then
be only more marked on the plant from Kodiak.

Kindberg has indicated from Alaska P. vancouvertensts Kindb. and P. sertata
Mitt.

This specimen agrees exactly with a scrap of the type kindly com-
municated by the Royal botanical museum of Berlin, but in the lat-
ter the leaves are more crowded, giving to the plant a still more
robust aspect. JZ. ¢schutschica differs from ML. triguetra Angstr. by
its larger size and broader leaf-cells.

drummondit Lesq. & Jam. by its leaves which are more crowded on
the whole stem, and not carinate-concave, and its capsule hanging and
with a mamillary lid.

From St. Lawrence Island (Trelease, 1871).

This species, which seems to belong to the group of ZB. alpinum
Huds., is chiefly characterized by its more acuminate and distinctly
denticulate leaves, and by its nerve disappearing below the apex.

This specimen agrees exactly with JZ. 22dam Williams, from Idaho
and Montana. Mr. Williams mentions as distinctive characters for
his species, in comparison with JZ. punctatum, nothing but the un-
thickened margin of-the leaf and the naked, not radiculose stems.
Now, in the European specimens of JZ. punctatum var. elatum, it
very often happens that the margin of the leaf is not thickened at all
or only slightly towards the base; this character, therefore, is not valu-
able. But, besides the naked or hardly radiculose stems and the
smaller height, AZ. xudum differs from JZ. punctatum var. elatum
by a more regularly hexagonal areolation, the cells towards the
margins being larger (45-55 » instead of 28—35) and the ones near the
costa of the same length as in the allied species (70-100 #) but broader
(50-60 », instead of 40-45); and the lid of AZ. zudum is shortly apic-
ulate, while in JZ. punctatum it is rather long beaked. However,
these distinctive characters are not of great importance, and it seems to
us preferable to regard AZ. xudum as a subspecies of JZ. punctatum.

This species is distinguished from JZ. punctatum by its cells which

a line generally very distinct, the larger spores (44-55 », instead of
30-40) and the higher peristome (0.75 millim., instead of 0.60).
Moreover the nerve is usually shorter than in JZ. punctatum.

286 CARDOT AND THERIOT . [326]

The moss which was described by Mr. Kindberg under the name of
B. lescuriz, from sterile specimens collected in Japan, does not seem
to be the true Africhum lescuriz James, because its leaves are only
incurvate and not crispate when dry. On the contrary, it is prob-
able that &. sttkana of Kindberg, equally described from sterile
specimens, differs in nothing from the species of James. The latter
was, after all, imperfectly known until now, the author having seen
neither the calyptra nor the lid, and having been unable to ascertain
the existence or absence of a peristome. Therefore, we here give a
complete description with drawings of this interesting moss, which, by
the absence of the peristome and chiefly by the structure of its leaves,
which, except on the borders, consist of two layers of cells, seems to
us to constitute a genus distinct from Atrichum.'

Dioicum, laxe cespitosum, atroviride. Caulis gracillimus, filiformis,
flexuosus, simplex furcatusve, laxe foliosus, inferne longissime denu-
datus, 2-8 cent. altus. Folia sicca crispatissima, madida arcuato-

From Douglas Island (Trelease, 1728, 2415); Port Etches (J. M.
Macoun).

A. leiophyllum Kindb. cannot be specifically distinguished from
A. parallelum Mitt., the characters put forward by Mr. Kindberg to
justify the creation of his species being liable to vary on the same
specimen. Such is more particularly the case with number 217 of
the Canadian Muscz, the leaves of which are sometimes destitute of
dentate crests on the back and sometimes possess them well-developed.

1See Note 2, p. 347.

[327] THE MOSSES OF ALASKA 287

On other specimens, coming from Vancouver Island, the crests are
more generally wanting; however, they are sometimes found and the
leaves often bear sparse teeth on the back toward the apex; moreover,
the nerve is always lamelliferous on both sides, at least in the upper
part.

From St. Lawrence Island (J. M. Macoun). New to Alaska.

Mr. Kindberg has attributed this moss to O. hercynicum typicum,
but it certainly belongs to his O. ¢xtegrifolium, characterized by its
broader leaves, smooth and entire on the back, and by the cells of the
leaf-areolation which are much larger; characters which appear to
us sufficient to admit of a specific distinction.

The specimens from St. Matthew Island have their stem-leaves a
little longer than those of the European specimens, their basilar cells
with thicker walls and their perichatial leaves hardly different from
the comal ones, and thus almost exactly agree with Catharinea (Psi-
lopilum) tschuctschica C. Miill., which does not appear to us a
good species.

No precise limits exist between P. alpinum and P. macountz.
Kindberg attributes 60 lamella to the leaves of his species, but
on the specimens which he sent to us we find only from 40 to 50
lamelle; and, on the other hand, P. al/pzzum, to which he at-
tributes only 30 lamellz, often has 40. (Cfr. Barclay, Muscinées de la
France, p. 198, and Limpricht, Laubmoose, 11, p. 615.) There is no
other more constant difference between the two mosses. P. macounti
is therefore only a variety of P. alpinum, characterized by its greater
dimensions, its longer leaves, more widely spreading when dry and
usually provided with more numerous lamelle (40 to 50). This var.
macount? represents an extreme form of P. alpinzum, of which the

[329] THE MOSSES OF ALASKA 289

other extreme is var. breviéfolium. In the specimens from Alaska we
find all gradations of form between the two varieties.

From Yukon River (W. H. Dall, in 1867).

This species is easily distinguished from the smaller forms of P.
commune by its short and entire leaves, its higher lamellae with more
deeply crenated borders and more strongly emarginated marginal cells.

A recently described species, P. jensentd Hagen (P. fragilifolium
Lindb. fil. mss.), which has been found in Greenland, Spitzbergen,
Lapland and Wyoming, comes very near our P. ywkonense by its
size and the height and structure of its lamella, but differs from it by
its leaves being longer and dentate at the point, by the cells of the
basilar and subvaginant part, which are wider, and by the much less
emarginated apical cells of the lamelle.

The specimens from St. Paul Island are remarkable by their leaves
being entire or nearly so, and provided with rounded auricles, larger
than in the type. In C. americanum Brid., the auricles are still more
developed, and the areolation is chiefly formed of much shorter and
wider cells. By its entire or subentire leaves, the form from St. Paul
Island comes near var. oregonense Ren. & Card.

Numbers 2056 of Trelease, and 753 in part of Coville and Kearney,
exactly agree with the type of Washington; the Muir Glacier plant
has the leaves somewhat wider at the base, but the form of the seg-
ments of the endostome and the other characters leave no doubt as to
its correct reference to P. stenophylla. Number 1759, from Yakutat
Bay, is a stouter and sterile form, the determination of which is rather
doubtful.

[333] THE MOSSES OF ALASKA 293

In his valuable Revision of the North American species of Pseudo-
leskea (Bull. Torr. Bot. Club, xxvir), Dr. Best has substituted the
name P. rigescens (Wils.) Lindb. for P. stenophylla Ren. & Card.
It is impossible for us to admit any well grounded reason for this
change; for, if Dr. Best saw, as he affirms, a specimen of Leskea
rigescens Wils. identical with P. stexophylla Ren. & Card., on the
other hand, we possess one which certainly belongs to P. radicosa
(Drummond, Musci Americani, no. 225). Moreover, Dr. Best him-
self acknowledges that both species were mixed up under this number
of Drummond’s exsiccata and under the name Hypxum congestum
Hook. & Wils. Now, as Wilson never described his Leskea rigescens,
it is impossible to know to which of the two species he wished to give
this name, and that must, therefore, be definitely abandoned. One of
the two species should be called P. radzcosa (Mitt.) Best, the other
should preserve the name P. stexophylla Ren. & Card.

other than Brachythectum reflexum Br. eur.

more chlorophyllose areolation, and by its narrower, short and often
bifurcate costa.

On these specimens nearly all the leaves are smooth on the back;
however we have found a few branches with papillose leaves,
which, added to the other characters, leaves no doubt as to their de-
termination. Moreover, even on the specimens from New England,
the leaves are sometimes quite smooth. This character is therefore
variable, which prevents us from admitting the genus Bryhnza.

Mr. A. J. Grout has recently ascertained that Hypxum chloropte-
rum C. Mill. & Kindb., from Canada, and 4. scabridum Lindb., from
Norway, should be reunited to B. xove-anglie (cf. Bull. Torr. Club,
XXV, pp. 229-231). The distribution of this species, as it is now
known, includes southern Norway, eastern Canada, Newfoundland,
Miquelon Island, the Eastern States as far south as Maryland and as
far west as Wisconsin, Alaska, the Bering Sea Islands and Japan.

This variety, which seems to occur along the Pacific Coast from
Oregon to Alaska, differs from the type by its stouter aspect, its stem-
leaves larger, less triangular, rather ovate-lanceolate, not so abruptly
acuminate, and revolute on the borders in the lower part, by its costa
thinner and generally vanishing at the base of the acumen, and by its
leaf-areolation composed of cells of the same width (about 9) butat
least twice longer (80-90, instead of 30-35); those in the angles
longer too, rectangular, seldom quadrate. These characters seem to
be constant, and perhaps Mr. Kindberg is right in considering this
moss as a species distinct from B. reflexum.

longer, with a more elongated and narrower acumen, and a closer
areolation, formed of longer and narrower cells. There is, however,
no doubt of the specific identity of the two specimens. This species
should be placed near . ste/latwm Schreb., from which it is distin-
guished by its much smaller dimensions, its short and fastigiate stems,
its leaves which are small, imbricate, shortly acuminate and for the
most part finely denticulate, and, finally, by its small, quadrate alar-
cells, the median ones shorter.

We do not distinguish from HZ. c¢rcrnale, H. sequoteti C. Miill. in
Flora, 1875, p. 91, the characters mentioned for the latter being in-
constant and of little importance. We must equally refer to 77. czr-
cinale the Raphidostegium pseudorecurvans Kindb. Not. on Canad.
bryol., 1893, according to the specimens of the latter which were com-
municated to us by Mr. J. M. Macoun.

As we have said elsewhere (Revue bryologique, 1890, p. 18, and
Hedwigia, 1893, p. 275) it was a mistake to describe 7. cércinale as
being monecious; it is certainly dicecious, for on a hundred speci-
mens that we have had the opportunity of examining, we have never
found flowers of both sexes on the same stem.

Hypnum alaske Kindb. Not. on Canad. bryol., 1893.

From Port Etches (J. M. Macoun).

This species appears to be very close to the preceding, judging from
the small specimen we received; however, it differs from it by its

smaller dimensions, its creeping and radiculose stems and its much
narrower leaves.

The alar cells are here a little more numerous than on the European
type; but we have specimens from the Pyrenees that are identical in this
respect with those from Alaska.

This species differs from 7. zmpfonens Hedw. by the auricles of the
leaves being formed of one or two large outer hyaline cells, the inner
cells being brown or yellowish.

From Bailey Harbor (U.S. S. Adéatross Exped.).

Although the areolation is a little closer than usual, the alar cells,
much more numerous than in 47. cupresstforme, do not seem to leave
any doubt on the determination of this moss.

Hypnum krausei C. Miill. in Flora, 1887, p. 224.

From Takhin valley (Dr. Krause).

This moss, that C. Miiller placed in his section ///ecebrzma, which
corresponds to the genus Scleropodium Br. eur., is certainlya Hygro-
hypnum (Limnobium Sch.), as appears from an examination of the
original specimen, which was communicated to us by the Royal Bo-
tanical Museum in Berlin. It comes near 7. subeugyrtum occidentale
Card. & Thér., but differs from it by its longer leaves, its almost scari-
ous and much less chlorophyllose areolation, and its thinner costa.

From Yukon River (W. H. Dall, in 1867).

This species resembles both H. stramineum Dicks. an} H. pseudo-
stramineum C. Miill.; but it is with the latter that it has the closest
affinity. It differs from it by its leaves being shorter, subdeltoid, with
a costa thicker (40-50 instead of 30-40), longer, usually exceeding
the 34, and finally by the firm areolation, formed of flexuous cells,
rather obtuse (not truncate) at the ends, with thick walls, and re-
sembling those of Hygrohypnum.

The comparative figures of 17. pseudo-stramineum given on Plate
XXIII, were supplied to us by Mons. Renauld, who drew them from an
original collected by C. Miiller at Halle-am-Saale.

Mr. Kindberg has described a H. pseudo-complexum Kindb. from Alaska, of

which we have not seen any specimen. WH. alaskanum Lesq. & Jam. is also
unknown to us.

This variety is Hylocomtum alaskanum of Kindberg, but we
much doubt whether it is the true Hypxum alaskanum of Lesquereux

[345] THE MOSSES OF ALASKA 395

and James (Proced. Amer. Acad., x1v, p. 139, and Manual, p. 405).
These authors compare their plant to Wyprum Schrebert, to which
this var. graczléus bears no resemblance, and attribute to it obtuse
leaves, whereas they are apiculate on the moss of which we are speak-
ing. Besides, it would be very surprising if such experienced bry-
ologists as Lesquereux and James had not noticed the evident relations
which would have existed between their species and Hylocomtum
splendens, if the identification proposed by Mr. Kindberg was exact.
Until the contrary is proved, we think that AZ. alaskanum Lesq. &
Jam. is a different species, much more resembling AZ. schreder¢ than
Lylocomium splendens.

rate from HZ. sguarrosum.

POSTSCRIPT.

Nore 1.—Since the completion of this paper for the press, in March,
1901, a very important catalogue of the bryophytes of the Yukon,
comprising 24 hepatics, 7 sphagna, and 222 mosses, has been published
by Mr. R. S. Williams, in the Bulletin of the New York Botanical
Garden. Mr. Williams’s list includes a large number of mosses that
are here indicated as new to Alaska. The following species, however,
to the number of fifty, are not found in Mr. Williams’s list :

[347] THE MOSSES OF ALASKA 307

Of the species and varieties here described as new only one, Lypnum
plestostramineum, may possibly be identical with one of Mr. Williams’s
new species, LZ. amblyphyllum.

It should also be added that Mr. Williams’s list contains 115 species
not found in our list, so that at present the total number of mosses
unquestionably shown to be Alaskan or of the Bering Sea islands is
about 350.

Note 2 (p. 326).—In.a recent paper in the Journal of Botany, vol.
39, pp- 339-341, Mr. E. S. Salmon points out that Bartramiopsis
lescurtt has the same leaf structure as Lyellia créspa, and he suggests
placing it in this genus. But Gartramdopsts differs from Lyellia by
its small, erect, symmetrical, not angular and macrostomate capsule,
and it seems preferable to keep it as a distinct genus.

NoTE 3 (p- 343)-—A preliminary diagnosis of this moss has been
published by Mr. Renauld in Bryologist, 1v, p. 65. It is perhaps the
same species as H. amblyphyllum Williams, in Bull. N. Y. Bot.
Garden, u, p. 139.

June, 1902.
