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.
