[Duss 508.] 



Plants of medium to large size, in yellow-, olive-, or dark green to brownish mats, 

 or among other bryophytes; stems highly variable, to 10 cm long, with leaves, to 

 4-5 mm wide, often much smaller, often becoming erect, small-leaved and gem- 

 miparous at the tips, irregularly branched; branches scarce to abundant, leafy or 

 flagelliform, or short sexual, ventral-intercalary from the axils of the underleaves; 

 stem in transverse section with the cortical cells similar to those of the medulla. 

 Rhizoids frequent, long, in hyaline, yellowish or brownish tufts from the bases of 

 the underleaves. Line of leaf insertion oblique and curved in the upper part. Leaves 

 distant to imbricate, ascendant-spreading, ovate from a broad base, the dorsal base 

 curved, the ventral base straight or sometimes decurrent in less robust plants, 

 narrowed to the shortly bifid apex, the segments short, triangular from a 2- to 4- 

 celled base, ending in a 1- or 2-celled tip, the sinus U-shaped; cells of the upper 

 part of the leaf hexagonal, regular, 26-39 X 26-39 n, the walls uniformly thin, 

 without trigones, the cuticle verruculose. Underleaves conspicuous, distant, broader 

 than the stem, transversely elliptical in outline, deeply set on the stem, bifid and 

 with a broad sinus, the teeth of segments usually broad, blunt, the lateral margins 

 convex and with a second broad tooth or projection on the margin, additional short 

 acute teeth sometimes present. Plants monoicous or dioicous (usually sterile). Male 

 inflorescence catkin-like, the bracts and bracteoles scale-like, in up to 6 series, con- 

 cave, imbricate. Female bracts and bracteoles in 3 or 4 series, small, scale-like, 

 remaining at the mouth of the sac. Perigynium cylindrical, to 2 mm long, bearing 

 rhizoids. Sporophyte not seen.
