Description:Latin Diagnosis - Caules foliosi, e caudice irregulariter ramoso, prostrato. Caulium cortex 6-15 seriebus, cellulis dorsalibus maioribus. Rhizoidea e basi amphigastriorum. Folia oblique inserta, succuba, bifida. Amphigastria bifida, raro trifida. Inflorescentia masculina terminalis vel intercalaris. Inflorescentia femínea in ramo brevi caudicis, bracteis bracteolisque bifidis. Perianthium 3-carinatum insuper, ore 3-lobato, setulo-ciliato.

Species Description - Plants small, consisting of a prostrate caudex and more or less ascending, somewhat complanate, leafy stems and flagelliform branches; branches of the caudex and the flagelliform branches axillary-intercalary, branches of the leafy axis infrequent, ventral-intercalary in the axils of the underleaves; stem in transverse section of a cortical layer of 6-15 cells, with the ventral rows smaller than the rest, surrounding 6-12 cells of the medulla. Rhizoids in tufts from the bases of the underleaves, or in 3 rows of tufts on the caudex and the flagelliform branches. Line of leaf insertion oblique, the leaves succubous. Leaves ovate-lanceolate, bifid to the middle, the segments lanceolate, the cells mostly longer than broad, the walls uniformly thickened. Underleaves conspicuous, bifid or occasionally trifid to the middle, the segments slender. Male inflorescence terminal becoming intercalary on the stem, the bracts and bracteoles similar to the leaves and underleaves, densely imbricate. Female inflorescence on a very short branch from the caudex or a flagelliform branch, the bracts and bracteoles in 3 or 4 series. Perianth 3-keeled above, the mouth 3-lobed, the lobes variously laciniate and ciliate. Vegetative reproduction from globose masses of cells formed on the caudex or the flagelliform branches.
