Description
Species Description - Plants of medium size to robust, coarse, light yellow-green, brown on drying, rarely tinged with red, prostrate in dense mats or among other bryophytes; stems to 3 cm or more long, with leaves 2.5 4 mm wide, irregularly branched, the branches intercalary, dorsi-axillary or ventral-axillary, leafy or flagelliform, or small-leaved and gemmiparous at the tip or sexual; in transverse section the stem 10-14 cells across, the cortical layer of 1 or 2 rows of small cells with thick walls, the medulla of larger cells with thinner walls and large trigones. Rhizoids abundant on the ventral side of the stem. Line of leaf insertion oblique. Leaves large, widely spreading, subrectangular, to 2 mm long, 1 mm wide, tending to be plane, the margins more or less undulate or crisped, here and there recurved; cells of the upper part of the leaf mostly 26 X 26 µ, the walls as thin pits between the large, rounded trigones, the cell cavity stellate, the marginal cells slightly smaller, the outer wall very thick, the cuticle verruculose. Underleaves small, broadly ovate, the margins, marginal projections, and much of the surface, covered with stalked or sessile slime papillae which may secrete quantities of slime. Plants dioicous. Male inflorescences in long or short whitish catkins on the ventral side of the stem, the flagelliform branches (in 1-3 rows) or sometimes terminal; bracts and bracteoles in up to 8 series, the bracts short, bilobed, concave, monandrous, the bracteoles tiny, ovate, bidentate. Female inflorescence on a very short dorsal or ventral branch, the bracts and bracteoles in 3 series, the innermost series largest, bifid to one-third, the segments triangular, the margins irregular. Perianth long, whitish, cylindrical below, 3-keeled above, the mouth contracted, incised, ciliate with long and short cilia. Gemmae light green, 2-celled.
