the walls soon becoming thick by deposits of secondary thickenings and coalesced 

 trigones. Male branches occasional, the bracts ovate, to 0.56 mm long, to 0.64 mm 

 broad at the base, the apex entire, or with two or three short teeth, the bracteoles 

 smaller; antheridia occurring singly. Female branches and sporophytes not 

 seen. Fig. 29, a-e.

Plants of medium size to large, light yellow-green, becoming yellow-brown ; 

 stems slender to robust, 5 cm or more long, with leaves to 4.5 mm broad, prostrate 

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

 branches numerous, long. Line of leaf insertion curved in its upper part. 

 Leaves distant to imbricate, often becoming deflexed when dry, asymmetrically 

 ovate, falcate, 1.5-3.0 mm long, 1.0-1.5 mm broad at the base, narrowed a little 

 to the more or less obliquely truncate, irregularly tridentate apex; teeth mostly 

 small, acute, to six cells long, three to five cells broad at the base, the sinuses 

 shallow, lunulate, the margins entire; leaf -cells thin-walled, the cell lumina 

 angular-rounded, the trigones conspicuous, with convex sides, soon becoming 

 coalesced through the deposition of secondary thickenings, the cuticle faintly 

 verruculose ; cells of the apical portion mostly 24 X 24 ft. Underleaves distant 

 to imbricate, subquadrate to orbicular, broader than the stem, 0.5-1.2 mm long, 

 0.5-0.95 mm broad at the base, the lateral margins convex from a rounded base, 

 entire, the apical portion rounded, entire, straight, to four-lobed, a little squar- 

 rose, the cells 24-32 n, thin-walled, the trigones large, often coalesced, inter-
