Description
Description - Stems prostrate, small, irregularly branched, the branches as in Eadula; rhizoids springing from the bases of the underleaves. Leaves complicate bilobed, the dorsal lobes larger than the ventral, incubous, attached by a long line, ovate to obovate, rounded to obtuse at the apex, entire or slightly crenulate; lobule when well developed inflated, acute, bearing a hyaline papilla at the base of the apical tooth on the side next to the stem; leaf-cells thin-walled but sometimes with small trigones. Underleaves ovate to orbicular, bifid, the division mostly entire or crenulate. Antheridia borne or in pairs in the axils of saccate bracts, the latter in more or less elongated androecia. Archegonia borne singly on branches variable in length with one or two subfloral innovations, the bracts with plane lobules, bractole bifid. Perianth inflated, five keeled, abruptly narrowed to a distinct tubular beak. [Commemorates A. L. S. Lejeune, Belgian botanist.] Xearly 200 species, mostly tropical. Type species: L. cavifolia (Ehrh.) Lindb.
