Characteristics

Paroicous? Green, sometimes with purple margins of the leaves, growing on wet soil. Stem to 10 mm long, usually about 5 mm, up to 250 µ in diameter, green-brown, frequently dark purple on the dorsal face, basally with leafless stolons. Leaves Ungulate-ellipsoid larger towards the apex of the shoot, alternate, hardly decurrent on the dorsal face. Marginal cells in a distinct row, rectangular, 16 x 22-30 x 40 µ, near the base longer on 20. The ventral side, up to 20 x 50 µ cells in the centre of the leaf rounded, 26-34 µ long, trigones of medium size, cuticle strongly papillose. Oil bodies yellowish, 1-3 per cell, 4 x 6-12 x 12-8 x 20 µ, homogeneous or composed of small drops. Amphigastria only present in the top below the female organs, frequently hyaline in the margin, entire-slightly dentate, broad, scale-like. Female organ terminal (only young ones observed), where the stem forms a cavity. Bracts smaller than the leaves, emarginate. Perianth shorter than the bracts, mouth irregularly dentate. Archegonia surrounded by paraphyses. The leaves in the vicinity of the bracts with small paraphyllous lobes at the base, paraphyses on the dorsal surface of the stem in this region. Rhizoids single, not in fascicles, slightly brownish. Gemmae disciform, up to 300 µ in diameter, arising from the dorsal surface of the stem near the apes.
