— II — 
species on specimens from a single collection or two collections from neigh- 
boring localties even. 
Following are the descriptions of the new species translated from the 
Latin. These descriptions of all the species are accompanied by good illus- 
trations. 
Bryum Minnesotense Card. & Ther. 
Dioicous, densely cespitose: stems 5-10 mm. high, erect, radiculose, 
with numerous innovations ; stem leaves erect-open when moist, appressed 
when dry, about 2 by 1-1.5 mm., ovate-lanceolate, short acuminate, entire or 
denticulate at apex, costa excurrent, margins revolute from base to apex; 
basal leaves larger, longer acuminate, somewhat twisted when dry: basal 
cells hyaline, elongated rectangular, medial and upper short-hexagonal, 
strongly chlorophyllose, marginal linear in 4-5 rows forming a distinct bor- 
der. Seta 2-2.5 mm. long, usually bent at base; capsule subhorizontal or 
cernuous, oblong-pyriform with a long plicate neck when dry; operculum 
conic: annulus broad, exostome as in B. pendulum , 0.36 mm. high, inner 
lamellae anastomosing. Endostome adherent, cilia not appendiculate. 
Spores 19-20 ju. Antheridial plants unknown. 
Differs from B . pendulum by its narrower, longer capsule, provided with 
a longer neck, longer cilia and dioicous inflorescence. 
At Granite Falls (June 13, 14, 1901). 
Bryum Holzingeri Card. & Ther. 
Closely related to the preceding from which it differs in the synoicous 
inflorescence, leaves narrower at base with margin less longly revolute, 
plane above, acumen longer, more distinctly denticulate at apex, median 
cells about twice longer, margin broader, composed of 6-7 rows of cells. 
Capsule longer and narrower for its length. 
The longer and narrower capsule distinguishes this species from B. 
pendulum. 
At Cedar Lake (June 18), Hartford (June 27) Foster (June 29, 1901). 
Catharinaea Macmillani Holz. 
Dioicous, archegonial heads only found. Plants not branching, reach- 
ing 2 cm. in length; leaves involute and circinate when dry, erect-open when 
moist, margin bistratose and constructed of two rows of cells, serrate with 
paired teeth; lamellae 7-10, 8-12 cells high, the terminal cell lightly papil- 
lose. Other characters not known. 
This species is at once distinguished by its papillose leaves. It is dedi- 
cated to Prof. Conway MacMillan, director of the Minnesota Botanical Sur- 
vey. On ground near Ortonville (June 25, 1901). 
Note — T he original spelling of the generic name is Catharinaea , not 
Catharinea. 
Fontinalis obscura Card. 
Plants rather soft, obscurely green to dark green, blankish below, stems 
10-15 cm. high, flexuous, denuded at base, irregularly or pinnately brancUed, 
branches patent to patulous, obtuse or short cuspidate; leaves rather 
densely foliate, slighly concave, rather soft erecto-patent, imbricated at the
