MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



[VOL. 11 



Plants slender, brownish-green becoming deep reddish-brown ; stems to 6 em 

 long, with leaves to 3 mm broad, depressed to ascending; lateral branches 

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

 frequent, long. Leaves approximate to subimbricate, deflexed when dry, asym- 

 metric, elongate-ovate, ascendent, 0.75-1.5 mm long, 0.5 mm broad at the base, 

 narrowed a little to the transversely truncate, bidentate apex ; teeth large, acute, 

 six to eight cells long, five to seven cells broad, margins crenulate, serrate, 

 or even shortly denticulate ; leaf -cells thin-walled, the lumina rounded, the 

 trigones small, conspicuous, rarely coalesced, the cuticle verruculose ; cells of 

 the apical region mostly 20 X 20 p. ; a vitta not conspicuous. Underleaves 

 distant to approximate, more or less quadrate in outline, mostly 0.26-0.32 mm 

 long and broad, the apex irregularly divided into irregular, long or short, 

 blunt to acute teeth, the lateral margins entire or variously toothed. Female 

 branches frequent, the bracts of the intermediate and innermost series ovate, 

 to one-half or more divided into two or three long, slender laciniae one or two 

 cells broad and twelve or more cells long, the lateral margins serrate to ciliate. 

 Perianth-mouth densely long-ciliate. Male bracts and sporophytes not seen.

Plants mostly large, light yellow-green at the growing tips becoming dark 

 brown; stems to 10 cm or more long, with leaves 2.0-2.5 mm wide, mostly 

 ascending to erect; lateral branches infrequent, diverging at a wide angle; 

 flagelliform branches numerous, long. Leaves imbricate, often becoming strongly 

 deflexed on drying so that dried stems appear to be laterally compressed, 

 asymmetrically ovate, more or less falcate, to 1 mm long, 0.6-0.72 mm wide at 

 the base, narrowing to the bidentate apex ; teeth acute, mostly eight to ten
