Dioicous, loosely cæspitose, or creeping, flagelliferous, small,
brownish-green or olive-brown. Stems diohotomously innovantly
branched, innovations proceeding from the axil of the stipules,
slender, fragile, cortical cells about 20, about 8 in diameter, all
similar ; flagella abundant, microphyllous ; radiculose, rootlets
fasciculate, hyaline. Leaves incubous, horizontal or patent-
divergent, distant or approximate, caducous, deflexed, convex or
plane, oblong-ovate or ovate, apex entire acute or irregularly bi-
tridentate; cells smallish to medium size, roundish, walls firm,
trigones large and distinct. Stipules patulous, orbicular, subrotund
or obovate, entire, retuse, emarginate, or irregularly crenate.
Andrcecia postical, proceeding from axil of stipule, bud-like,
globular. Perigonial bracts 4, 5 pairs, concave-complicate, broadly
ovate, bidentate, sinus and segments small, acute; bracteole oval-
orbicular, retuse. Antheridia solitary, oval, stipitate.
