Plants large, dull olive-green to brownish-green, light yellow-green at the 

 growing tips; stems stout, to 10 em or more long, with leaves to 5 mm wide; 

 lateral branches numerous, 1 em or more apart, diverging at a wide angle; 

 flagelliform branches numerous, long, often branched. Line of leaf insertion 

 curved in the upper part. Leaves widely spreading, imbricate, nearly plane, 

 becoming convex on drying, often strongly deflexed, asymmetrically ovate, to 

 3 cm long on robust plants, to 1.5 mm wide at the base, narrowing to the trans- 

 versely truncate, tridentate apex; teeth spreading, deltoid, acute to subobtuse, 

 mostly unequal, three to seven cells long, three to seven cells wide at the base, 

 the sinuses broad, the margins straight to undulate; leaf-cells thin-walled, the 

 trigones small to large with convex sides, the lumina angular-rounded to stel- 

 late, the cuticle verruculose ; cells of the apical portion 25 p. long X 21 p. Under- 

 leaves round-quadrate, broader than the stem, mostly 0.7-0.8 mm long, 0.8-1.0 

 mm wide, with a hyaline border of four to eight or more rows of cells, the 

 apical margin broadly undulate, with three or four lobes, the bases rounded to 

 semi-cordate ; hyaline cells 18-30 p. X 15-18 p, thin-walled, with few trigones, 

 the chlorophyllose cells with conspicuous trigones. Male branches to 1 mm 

 long, the bracts broadly ovate, 0.6 X 0.5-0.6 mm wide, strongly concave, bi- or 

 tridentate with short, broad teeth, the braeteoles smaller; antheridia borne 

 singly or in pairs. Female branches several on a stem, the bracts of the inner- 

 most series 1.5-1.8 mm long X 0.85-0.95 mm wide at the base, divided to one- 

 third or one-fourth their length into two to four long, narrow, crenulate seg- 

 ments. Perianth long, the mouth contracted, short -ciliate to dentate. Sporo- 

 phyte capsule 1.5 mm long, ovoid-cylindric, of four or five layers of cells. 

 Elaters 390 p long, 18 p wide, bispiral. Spores 15-18 p., minutely punctate.
