N ot as common as C. cladorrhizans, from which it is distinguished at
first sight by tlie shorter yellow pedicel of the capsule.
4. 0 . Floridanum, Duby. Stems prostrate, dirty green;
branches close, irregular, with short erect branchlets: leaves
subpellucid, imbricate, ecostate, narrowly lanceolate, acute or
acuminate, minutely serrulate at the apex ; perichætial leaves
long-lanceolate, very entire : iiedicels clustered (3 or 4), erect,
strict, bright purple, slightly enlarged under the capsule ; capsule
brown, horizontal or suberect, ovate ; operculum rostrate,
acute from a conical base, a little incurved; peristome and
areolation as in C. seductrix. — Regensb. Flora, Iviii. 284
(1875).
H a b . Florida (Chapman).
Tlie author compares it to C. seductrix. Tliis may be right for some of
th e characters, but the horizontal ovate clustered capsules and th e nar-
roYvlylanceolate-acuniiiiate leaves are characters not accordant with those
of the genus.

filling the whole base, the capsule shorter, inflated at the neck,

striolate, and the annulus wanting. — Sulliv. Mosses of U. States,

Plants large, tree-like, arising from a subterranean radiculose
stem ; primary branches erect, simple below, fasciculately
branching above. Leaves of the primary branches squamiform ;
those of the divisions crowded, erect-spreading, imbricate when
dry, decnrrent, thinly costate. Flowers dioeoious or abnormally
monoecious ; perichætial leaves long-sheathing. Fruit clustered.
Calyptra dimidiate, long, embracing the base of the pedicel.
Capsule long-pedicellate, erect, cylindrical-oblong. Operculum
rostrate. Teeth confluent above the orifice of the capsule,
linear-lanceolate, closely articulate ; segments arising from a
very narrow membrane, as long as the teeth, cleft between
