has shorter stems, more serrate leaves, not twisted when dry and a longer 
capsule. 
Bryum subdrepanocarpum Card. & Ther. 
Dioicous, loosely caespitose, green. Stems short, 5-7 mm. high, radicu- 
lose below, forming [slender loosely foliate innovations under the perichae- 
tium. Lower leaves remote, upper crowded into a small rosette, 1-1.5 mm. 
long, 0.6-0.75 mm. broad, ovate-oblong, short-acuminate; margins longly 
revolute, plane and denticulate in the upper part; costa 80 // thick at base, 
vanishing usually below the apex; areolation lax, basal cells rectangular, 
median and upper oblong-hexagonal, 6o// long, 18-20// broad, marginal cells 
1-2 rows narrow, linear, yellowish. Seta reddish below, pale above, 1.5-2 
cm. long. Capsule pendulous or nodding, oblong, arculate, with a long neck ; 
operculum convex-apiculate. Annulus broad. Peristome perfect, cilia 
appendiculate. Spores 8-12 // thick. Plate XXII.

This moss is very near B. drepanocarpmn Philib., from which it differs 
by its shorter and broader leaves, denticulate in the upper part, and form- 
ing a small rosette or bud at the top of each stem, and by its costa generally 
vanishing below the apex. 
Bryum camptocarpum Card. & Ther. 
Monoicous, rather laxly caespitose, yellowish green. Stems short, about 
5 mm. high, radiculose, simple or branching. Leaves erect, quite crowded, 
oblong -lanceolate, acuminate, middle and upper leaves 2 mm. long, 0.6-0. 7 
mm. broad, the lower shorter: margins incrassate, plane or barely reflexed 
below, subdenticulate towards the apex ; costa reddish, 80-90 // thick at base, 
shorter in the lower leaves, longer excurrent in the upper leaves: median 
and upper cells hexagonal and rhomboidal, 54-70 // long, 18-24// broad, basal 
cells rectangular, 80-90 // long, 20-30// broad, marginal cells bi- or tri-stratose, 
forming a beautiful distinct yellowish incrassate border. Male flower on a 
separate terminal branch. Capsule nodding, oblong, arcuate, 4-4,5 mm. 
long, 1 mm. broad, tapering into a neck as long as the sporangium ; opercu- 
lum convex, short apiculate. Seta reddish, 1.5-3 cm. long. Annulus double 
and triple. Peristome perfect, 0.48 mm. high; membrane of the inner peri- 
stome extending more than half the height of the teeth: processes narrowly 
gaping for a short distance along thejkeel; cilia 1-3, appendiculate. Spores 
papillose, 24// in diameter. Plate XXII.

1895). 
Allied to B. meesoides Kindb., B. drepanocarpum Philib., and A*, subdre- 
panocarpum Card. & Ther. by the form of the capsule, but distinct from 
these species by the monoicous inflorescence and by the leaves plane on the 
margins, or nearly so, with a very distinct and thickened border. It also 
much resembles B. pal lens Sw. var. arcuatum Sch., from which, however, 
it differs by the shorter leaves, with margins plane or scarcely reflexed at 
base and denticulate or sinuate at apex.
