Plants delicate, of medium size, olive-green, becoming brown in the older 

 portions; stems to 3 cm or more long, with leaves to 2.5 mm broad; lateral 

 branches frequent, mostly 5 em apart, diverging at a wide angle ; flagelliform 

 branches frequent. Line of leaf insertion curved in its upper part. Leaves 

 imbricate, plane to deflexed, asymmetrically ovate, spreading, 1—1.5 mm long, 

 0.5 mm broad at the base, narrowed a little to the transversely truncate, tri- 

 dentate apex; teeth narrow, sharp, five to eight cells long, four to six cells 

 broad at the base, usually ending in a row of two cells, the sinuses broad, 

 lunulate, the margins mostly entire; leaf-cells quadrate, with thin walls and 

 minute trigones, the lumina rounded, the cuticle faintly verruculose ; cells of 

 the apical region mostly 16-20 X 18 /*. Underleaves distant to imbricate, round- 

 quadrate, broader than the stem, 0.55-0.65 mm long X 0.5-0.6 mm broad, 

 sometimes hyaline in part, the apex mostly entire, repand to undulate. Sexual 

 branches not seen. Fig. 12, a-e.
