several teeth, the ventral margin with an occasional tooth, quadrifid to one-fourth 

 of their length; segments unequal, triangular from a 6- to 10-celled base, acute; 

 leaf-cells of the base of the segments quadrate, 18-24 (i, the walls thickened, the 

 cuticle smooth. Underleaves nearly as broad as the stem, broader than long, 

 quadrifid to the middle, the segments narrowly triangular from a 3- to 4-celled 

 base, the margins of the lamina convex, bearing several teeth. Female inflo- 

 rescence occasional, the innermost female bracts orbicular, crenulate-short ciliate 

 above. Perianth to 6 mm long, the mouth contracted, crenulate. Male inflo- 

 rescence not seen. PI. 44. Fig. 27, a, b.

Plants small, light green to yellowish or brown, in depressed mats or among 

 other bryophytes; stems to 6 cm long, with leaves 0.48-0.8 mm broad, becoming 

 tripinnate, the lateral branches 2-3 mm apart, sometimes becoming flagelliform, 

 0.5-1.0 cm long; the ventral branches not seen. Line of leaf insertion oblique. 

 Stem leaves small, distant, subquadrate to rectangular, plane to concave with 

 incurved segments, 0.3-0.6 mm long, 0.4-0.6 mm wide at the base, the dorsal 

 margin slightly concave, the ventral margin straight, entire, quadrifid to 

 one-fourth of their length; segments in pairs, triangular from a 2- to 6-celled 

 base, with a tip of one or two cells; leaf-cells at the base of the segment

 Underleaves scarcely as broad as the stem, quadrifid to the middle, the segments 

 mostly broad, triangular from a 3- to 4-celled base, ending in a tip one or two
