Plants large, ochraeeous yellow to dark brown, greenish in the younger por- 

 tions; stems robust, to 10 cm long, with leaves to 6 mm broad, depressed to 

 ascending; lateral branches frequent, diverging at a wide angle; flagelliform 

 branches frequent, short, with 3 rows of large, scale-like, ovate leaves, 0.25-0.33 

 mm long. Leaves densely imbricate, convex, deflexed, connivent when dry, asym- 

 metrically long-ovate, somewhat falcate, to 3.5 mm long, 2 mm broad at the base, 

 narrowing to the mostly 0.65 mm broad, truncate, tridentate apex, the dorsal 

 base deeply cordate, sometimes with a marginal appendage, the ventral auricle 

 large, oblong to rounded, undulate, entire or toothed ; teeth broadly triangular, 

 acute, five to eight cells broad at the base, to six cells high, widely spreading, 

 the margins straight to repand; leaf-cells with thickened walls, the lumina stel- 

 late, the trigones very large, with convex sides, mostly confluent with narrow 

 pits ; cells of the apical portion 18 p in diameter, the cuticle faintly verruculose. 

 rnderleaves imbricate, subquadrate, 0.8-1 mm long from the line of attachment, 

 the base cordate, the auricles large, undulate, rounded or toothed, the lateral 

 margins sinuate, or short toothed, the apex undulate to 2— 4-lobed or occasionally 

 toothed. Female branches occasional, the bracts of the intermediate and inner- 

 most series similar, long-ovate, divided to one-fifth or one-sixth of their length 

 into two or three crenulate teeth, six to ten cells long, four to six cells broad at 

 the base, the cells 45-72 X 22 p., with unequally thickened walls. Perianth long, 

 the mouth laciniate, the laeiniae six to twelve cells long. Male branches and 

 sporophyte not seen. Fig. 42, a-h.
