Plants very short, gregarious, simple. Leaves lanceolate-
suhulate, minutely serrate. Flowers monoecious, without para-
physGS. Capsule erect, subturbinate, distinctly short-necked,
soft, thin, gymnostome, macrostome and exannulate ; pedicel
straight, comparatively long. Operculum large, short-beaked.
1. A. Do n ian u s, Bruch & Schimp. Leaves deeply canaliculate,
with a strong continuous nerve mostly composing the
apex ; basilar cells of the areolation rectangular, empty, the
upper quadrate, small, chlorophyllose. — Bryol. Eur. t. 109.

3 4 . SELIGERIA, Bruch & Schimp. (PI. 1.)
Plants slightly more robust than in the last genus. Lower
leaves very small, distant, the upper abruptly tufted and much
longer, entire ; costa stronger upwards, semi-terete or canaliculate.
Capsule subglobose, of thick texture, tumid at the
collum, turbinate when empty. Lid large at the base, subulate-
beaked. Peristome of 16 broad solid teeth, linear-lanceolate,
obtuse or pointed, free to the base, smooth, orange, without
dividing lines, inflexed when moistened, reflexed when dry.
1. S. p u s illa , Bruch & Schimp. Plants very small, soft,
bright green, loosely cespitose : lower leaves narrowly lanceolate,
the upper long, narrowly linear from a broader concave
base ; costa slender, vanishing below the apex, translucent ;
borders nearly entire, very narrow, distinct to near the apex ;
perichætial leaves half-olasping at base, lanceolate, subulate
above : male flowers terminal on separate branches or sessile
under the perichætium : capsule ribbed when dry, on a comparatively
long strict yellowish pedicel ; lid oblique, subulatebeaked.

2. S. c a lc a re a , Bruch & Schimp. Differs from the preceding
in the shorter and broader leaves, the lower lanceolate,
the upper ovate, oblong at base, concave, abruptly narrowed to
a subulate blunt apex, the costa flat, enlarged upward and filling
the whole width of the lamina ; capsule larger, more solid,
with the beak of the lid shorter, and the teeth broader and
more densely articulate: spores larger.— Bryol. Eur. t. 110;

3. S. re c u rv a ta , Bruch & Schimp. Plants widely cespitose,
very short : upper leaves oval-lanceolate at base, canaliculate
above, long-subulate by the excurrent costa, entire ; perichætial
leaves sheathing, tubulose at base, lanceolate-subulate, flexuous
above : capsule subglobose, inflated at the collum, thin, loosely
areolate, red at the orifice ; pedicel long, yellowish, arcuate
when moistened, erect when dry ; lid straight, subulate-beaked ;
teeth linear, obtuse or lanceolate, sometimes irregularly bifid at
the apex. — Bryol. Eur. t. 112. Grimmia recurvata, Hedw.

4. S. tris tic h a , Bruch & Schimp. Plants rigid and cespitose,
short, branching : leaves distinctly three-ranked, close,
rigid, elliptical, whitish at base, narrowly linear to the blunt
apex ; perichætial leaves longer, subulate and recurved at the
apex ; costa excurrent : capsule as in the precedmg species ;
