Plants of medium size to large, dark green, becoming brown ; stems stout r 

 to 5 cm or more in length, with leaves to 4 cm broad, prostrate to suberect; 

 lateral branches frequent, 1 cm or more apart, diverging at a wide angle - r 

 flagelliform branches frequent. Line of leaf insertion curved in the upper part. 

 Leaves imbricate, plane to deflexed, asymmetrically ovate, spreading, 1.8-2.3 

 mm long, 1 mm broad at the base, narrowed to the obliquely truncate, irregu- 

 larly tridentate apex; teeth broad, three to five cells high, four to seven cells 

 wide at the base, the sinuses lunulate, the margins entire : leaf -cells thin-walled, 

 the lumina angular-rounded, the trigones large, distinct, often becoming coa- 

 lesced, the cuticle smooth to faintly verruculose ; cells of the apical portion 

 mostly 20-24 p. ; underleaves imbricate, subquadrate, broader than the stem, 

 0.7-0.85 mm long, 0.6-0.7 mm wide, the lateral margins often lobed, the apex 

 usually with a short, incurved tooth at either end, and undulate to lobed be- 

 tween. Sexual branches not seen. Fig. 16, a-c.
