IlAB. Surface and fissures of damp or shaded overhanging rocks, in the
mountains especiaily, not rare. The variety on caicareous rocks, Dalias
County, Texas {E. Hall).
This and the next species are extremeiy variable, and some of the varieties
are indifferently referable to one or the otlier. Var. stelligerum, which
represents G. stelligerum and G. articulatum, Smith, and G. pomiferum,
Nees & Ilornscli., is considered by Wilson and others as a variety of
G. currirostrim. It is apparently from sterile plants of one of the
numerous varieties of tliis species that G. Clintoni, Aust. (Bull. Torr.
Club, vi. 42), has been made.
3. G. c u rv iro s trum , Hedw. Plants dark red or brown,
soft or solid, 1 to 10 cent, long, with close fastigiate branches
more or less covered with a reddish felt of radicles : leaves
spreading, slightly incurved when dry, lanceolate-acute, concave
at the liyaline base, carinate above, smooth or slightly papillose,
with borders entire or sometimes slightly serrate and recurved
above the base ; costa vanishing under the apex ; capsule long-
pedicellate, ovate, oblong or sub-globose, thick-walled, chestnut-
color, shining, turbinate when dry and empty ; lid enlarged and
conical at base, prolonged into a long oblique tubular beak remaining
attached to the columella and persisting long after disruption
from the orifice of the capsule ; annulus of a double row
of small persistent cells : spores larger than in the precedmg. —

IlAB. Limestone rocks, and on deposits of carbonate of lime or tufa,
near springs; very abundant at Niagara Falls.
4. G. ten u e, Schrader. Plants very small, 1 m.m. high,
widely subcespitose : leaves linear, gradually narrower to the
obtuse apex, concave ; perichætial leaves sheathing to the
middle, there recurved, thinly costate, the inner ecostate and
smaller ; capsule oblongrelliptical ; lid short-beaked ; annulus
broad ; peristome mostly none or composed of minute narrow
teeth. — Coll. PL Crypt, n. 31 ; Bryol. Eur. t. 30. Gyroweisia

12. ANOEOTANGIUM, Schwaegr. (in part).
Plants compactedly pulvinate-cespitose, with dichotomous
and fastigiate branches, radiculose their whole length. Leaves
spreading, lanceolate or linear-lanceolate, subulate, opaque,
densely papillose, with a round costa. Flowers monoecious.
Capsule erect, oval or sub-globose, with a short inflated collum,
smooth, of thin texture ; lid obliquely long-beaked ; annulus
very narrow. Spores small.
A strange genus [genus paradoxuin, as Schimper calls it), with the
dichotomous fastigiate ramification of the Pleurocarpi, but a true Gym-
nostomum in the sliape of the leaves, their areolation, and the organization
of the capsule.

the essential characters of which are indicated in the description
of the genus, differing merely in the great size of the plants, the
much longer narrowly lanceolate leaves gradually increasing in
length upward, subulate-pointed, slightly contracted above the
short concave ovate clasping base, carinate-plicate above ; areolation
more distinctly quadrangular in the upper part of the leaves
and chlorophyllose at the base ; fruit unknown. — Aust. Muse.

2. Peristome simple.
13. W E IS IA , Hedw. (PL 1.)
Mosses of small size, cespitose or pulvinate. Leaves lanceolate
or linear-lanceolate and subulate, twisted when dry. Flowers
monoecious or dioecious, rarely synoecious. Capsule long-pedicel-
late, erect, oval-oblong, symmetrical or rarely slightly incurved,
with a peristome of 16 more or less perfect lanceolate teeth,
either entire or jferforated or split at the apex, or to the middle,
solid, transversely articulate, granulose, slightly marked with a
vertical divisural line. Spores large, verrucose.
1. W. v irid u la , Brid. Monoecious. Plants more or less
densely cespitose and pulvinate, bright green : stems about i
cent, long, nearly simple or with fastigiate branches : lower
leaves minute, the upper abruptly much longer, open and flexuous,
críspate when dry, linear-lanceolate, mucronate by the
stout excurrent costa, enlarged at the pale concave a,nd flat-
margined base, tubulose in the upper part by the involute
