the walls thin, the trigones small, with concave sides, the cuticle verruculose. Under-

3. Odontoschisma stoloniferum (Lindenberg & Gottsche) Stephani, Spec. Hep. 



3: 372. 1908. 



Sphagnoecetis stolonijera Lindenberg & Gottsche in G. L. & N. Syn. Hep. 688. 1847. 



Plants of medium size, the stems tufted from a rhizomatous base, ascending 

 or creeping, pale green to yellow-brown, caespitose or among other bryophytes; leafy 

 stems numerous from a common stolon "joint," to 2.5 cm long, sometimes becoming 

 stolon-like at the tip, with leaves, to 1.5 mm wide, occasionally branched; branches 

 ventral-intercalary, leafy or long stolon-like, branches of the stolons in 3 rows. 

 Rhizoids few, from the ventral side of the stem. Line of leaf insertion oblique. 

 Leaves spreading, more or less ascendant, imbricate, long-oval, the sides parallel, 

 the apex broad rounded, the margin (1 or 2 rows of cells) tending to curve upward; 

 cells of the margin 20 X 20 n, with thickened walls, cells of the apical part of the 

 leaf 15-20 X 15-20 /x, with thinner walls and small trigones, the cuticle verruculose. 

 Underleaves very small, inconspicuous. Plants dioicous. Female inflorescence a short 

 branch, the bracts and bracteoles in 3 series, ovate, the innermost series largest, bifid 

 to one-third the length, the segments broadly triangular. Perianth 3.5-4 mm long, 

 cylindrical below, 3-keeled and plicate above, the mouth weakly crenulate. Male 

 inflorescence not seen.
