branches simple, or forked,
delicate, flexible. Leaves
rather closely placed, bifarious,
remarkably concave,
roundish, approaching to
ovate, broader than long,
divided half way down
from the apex by a rather

acuminate, incurved in a
striking manner (figs. 74,

74- 75-

six or seven, resembling the rest, but the
segments less acuminate, and not incurved.
Calyx oblong or oblong-ovate, a little
plicate above, mouth somewhat contracted,

with a few short teeth. Capsule ovate, deep brown.
Elaters bispiral.
Dr. Carrington contends that this is the most
distinct and least variable of all the bicuspidate
species. Eng. Pot. t. 1304, and Hooker’s Jung,
t. xvi., both represent states of C. bicuspidata.
It occurs in neat compact strata, the stems
gracile, of equal width throughout, and from the
convexity of the leaves looking like strings of small
beads. These have a silky lustre, and are usually
of a bright pink or claret colour, but sometimes
pale green. The leaves are vertical, unsymmetri-
cal, cordate, broader than long, very convex, con-
duplicate, gibbous posteriorly, with the margin
ini exed and tumid, bicornute, the ventral tooth
not continuous with the border, but arising at
some distance within it, segments long and curved
liked the horns of an ox. The axillary leaves are
cordate-lanceolate, and have only one tooth, while
in the perichætial leaves there are two shorter
dentate segments. The texture is thin and silky,
the areolæ quadrate, discrete, surrounded by a
pellucid border.
