Description:Description - Dark green or more or less pigmented with yellow, brown or red. Stems prostrate, ascending or pendent, more or less copiously branched, the branches all arising at the bases of leaves without lobules, rhizoids springing from the bases of the underleaves. Leaves deeply complicate-bilobed, the dorsal lobes much larger than the ventral, incubous, widely spreading, ovate to orbicular, usually entire, lobule normally inflated, helmet-shaped; leaf-cells with distinct trigones; ocelli present in certain species. Underleaves smaller than the leaves, usually bifid. Antheridia mostly in pairs, in the axils of inflated bracts with explanate lobules, the bracts imbricated and forming short or more or less elongated androecia. Female inflorescence borne on a more or less elongated, branch, without innovations; bracts larger than the leaves, with explanate lobules and often more or less connate with the bifid bracteole. Perianth normally 3-keeled, with one keel ventral, but often with supplementary folds, abruptly contracted into a short tubular beak. [Commemorates L. Frullani, a Florentine minister of state.] A very large genus, 800 or more described species, mostly tropical. Type species: F. dilatata (L.) Dumort.
