3 5 . B L IN D IA , Bruch & Schimp.
Plants of larger size, densely cespitose, branching by innovations
from under the apex, fastigiate when old. Loaves crowded,
open or secund, broadly lanceolate at base, subulate, canaliculate
and costate to the apex, glossy; areolation narrow, quadrate
toward the apex, linear at base, enlarged and orange-
colored at the basilar angles. Flowers dioecious; perichætium
sheathing. Calyptra large, covering the capsule to the middle.
Capsule exserted on a long or short pedicel, subglobose, solid,
inflated at the collum; peristome of 16 equidistant lanceolate
teeth, entire or perforated or bifid at the apex, purple, erect
when dry, arcuate and connivent when moistened, distantly
articulate.
1. B. a c u ta , Bruch & Schimp. Tufts olive or yellowish
green; plants variable in size, one to fifteen c.m. long, the
slender stem mostly naked in the lower part. — Bryol. Eur.

H a b . On wet rocks, Rocky Mountains (Drummond) ; Cauterskill River,
New York (Lesquereux); White Mountains (James); Oregon (Hall).
3 6 . BRACHYODUS, Fuernr.
Plants very small, densely gregarious. Leaves lanceolate,
subulate, tufted, with a semiterete excurrent costa ; areolation
minute and quadrate toward the apex, rectangular-hexagonal
and smooth in the lower part. Flowers monoecious, terminal ;
antheridia without paraphyses. Caljqitra erect, conical, five-
lobate at base, split on one side to near the apex. Capsule
gradually enlarged from the top of the pedicel, erect, oblong,
soft, substriate; lid convex at base, abruptly long-subulate,
crenulate on the borders. Teeth of the peristome hyaline,
punctulate, sometimes perforate, confluent at base, broad and
truncate, rarely lanceolate, entire. Annulus compound, very
large, persistent.
Schimper (Syn. Muse. ed. 2, 132) calls this genus paradoxical, but considers
it more related to the Selig erice than to any other. Another species
(B. flexisetus, Hampe) is found in the Andes of South America.
1. B. trich o d e s, Fuernr. Plants simple : lower leaves
small, obscurely cordate, the upper much longer, subulate
from the ovate concave base : capsule deeply wrinkled lengthwise
when old ; pedicel twisted to the left in the upper part,
to the right in the lower. — Regensb. Flora, x., Beil. 112 ; Nees &

3 7 . CAMPYLOSTELEUM, Bruch & Schimp.
Plants densely gregarious, very short, delicate. Leaves subulate
; areolation minutely quadrate and chlorophyllose in the
upper part, hexagonal, rectangular and hyaline in the lower.
Capsule of thin texture, on a slender geniculate or arcuate
pedicel. Teeth of the peristome 16, lanceolate-subulate, split
to the middle or to the base. Annulus broad, compound,
revoluble. Spores very small.
■ This genus is placed by Lindberg and Braithwaite with Glyphomitrium
and Coscinodon.
1. 0 . sax íco la , Bruch & Schimp. Stem radiculose at
base : lower leaves minute, lanceolate, the upper densely tufted,
long-linear, subulate from the lanceolate base, concave, slightly
recurved when moistened, subcrispate when dry ; costa thick,
pei-current; perichætial leaves enlarged, concave at base,
narrower upward : flowers monoecious ; male buds on a short
basilar branch ; capsule oblong, cylindrical, oval, pale red at the
orifice, declined on a long very slender pale geniculate pedicel ;
lid with a very long subulate beak ; teeth reddish at base, pale
and punctulate at the apex of the narrow linear segments. —
