Leaves erect-appressed, 2 mm. by 1 mm., ovate-lanceolate, acutely acumi- 
nate, a little decurrent at base, margins plane and entire, costa 80 fi thick 
below, short excurrent, basal cells quadrate or short-rectangular, subin- 
flated, 40-60 ju by 25-40 //, median hexagono-rhomboidal 40 by 18-20//, four 
to five rows, marginal cells of the upper two-thirds narrow, linear forming a 
sort of yellowish margin. Seta reddish, pale above, more or less flexuous, 
2-2.5 cm. long: capsule 2-2.5 mm. long by 0.75 mm. wide, pendulous or cernu- 
ous, ovate-pyriform, narrowed into a neck equalling the sporangium, pale 
yellow, plicate with age, scarcely constricted under the mouth, walls soft 
with numerous superficial stomata, operculum convex, obtusely apiculate, 
annulus broad. Teeth 0.44 mm. high, formed of 20-25 joints, basal mem- 
brane very wide extending more than half the length of the teeth, seg- 
ments widely open along the keel, cilia one or two more or less elongated, 
granulose. Spores 18-20 ju in diameter. Seemingly dioicous (antheridial 
buds not seen on fruiting plants). Plate XX. 
Nevada: Marlette Lake, Washoe Co., on stream bank (C. F. Baker, 
1902). 
Resembles in habit W. gracilis DeNot., but much stronger, with a very 
different areolation of broad and short cells. The leaf areolation recall that 
of the genus Mniobryum Limpr., but the stomata of the capsule are super- 
ficial and the annulus is quite distinct. 
Webera Debati Card. & Ther. 
In loose yellowish-green tufts, with the habit of Philonotis. Stems 
1 .5-2.5 cm. high, densely radiculose below, tomentose above, with slen- 
der erect innovations. Lower leaves rather remote, erect-spreading, upper 
leaves closer appressed, about 1.3 mm. long by 0.33 mm. broad, lanceolate, 
acute, not at all decurrent; margins plane throughout, denticulate nearly to 
base; costa 40 ju thick at base, vanishing below the apex; median cells linear, 
140-170/q 28-30 yu broad, the lower cells broader and shorter, rectangular or 
subhexagonal, marginal cells longer, narrowly linear. Other characters 
unknown. Plate XX. 
North America: Alexander Co. (Herb. L. Debat. without name of col-- 
lector). 
This species seems closely connected with W. annotina Bruch., from 
which it is distinguished by the larger size, the habit resembling that of a 
small Philonotis, the tomentose stems and the leaves plane on the margins. 
Bryum pendulum Sch. var. Nevadense Card. & Ther. 
Differs from the type in the more slender capsule, similar to that of the 
var. angustatum Ren., but larger; in the convex-apiculate operculum, 
which is not at all conic; and finally in the leaves and costa which are green, 
not red at base. 
Nevada: King’s Canon, near Carson, along stream (C. F. Baker, 1902). 
Bryum polycladum Card. & Ther. 
Synoicous, in broad dense tufts, fuscous within, bright green above. 
Stems short, 3-5 mm. high, ^ranches slender, erect, numerous, arising from 
below the perichsetium. Leaves erect-appressed, crowded, the lower short,
