Oe d e e II. ANDREJSACEAS. S chizocaepous M o s se s .
Plants ascending from a prostrate rooting base, of dark color
and generally black, branching by innovations from under the
flower-bearing apex, and dichotomous. Leaves thickish, open
or falcate-secund, papillose or warty; areolation circular or
hexagonal in the upper part, quadrate in the lower, sinuous-
vermicular at base. Flowers monoecious or dicEcious, terminal,
gemmiforrn. Calyptra very thin, closely adherent. Capsule
oval, immersed in the large perichaetiiim before maturity and
then protruded by the elongation of the receptacle or vaginule,
splitting from the collum upward into 4 or rarely 6 equal segments,
which cohere at the quadrangular apex. Spores small,
at first coherent by fours in glomerules.
Plants cespitose, growing on rocks in alpine or subalpine localities; all
the American species monoecious.
