MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



[VOL. 11 



Plants large, pale green to light brown, in loose tufts or mats or among other 

 bryophytes; stems 5-8 cm long, with leaves to 1 mm broad, mostly ascendent, 

 bi-tripinnate, the lateral branches mostly 5 mm apart, 1-3 cm long, decurved at 

 the tips, sometimes becoming flagelliform, ventral branches not seen. Line of 

 leaf insertion subtransverse to oblique. Stem leaves distant to approximate, 

 asymmetric, ovate, cucullate-concave to saccate, 0.5-0.6 mm long, 0.5 mm wide 

 at the base, the dorsal margin strongly convex, the ventral margin much shorter, 

 to only one-fourth as long, without teeth, obliquely quadrifid to one-fourth of their 

 length; segments unequal, short, incurved, triangular from a 3- to 5-celled base, 

 soon becoming uniseriate with a sharp 2- or 3-celled tip, the cells to 27 p. long; 

 leaf-cells at the base of a segment 18-27x16-18 p., the walls thickened, the 

 lumina rounded, the cuticle smooth. Stem underleaves distant, not as wide as 

 the stem, quadrifid to one-half of their length, the segments narrowly triangular, 

 with a uniseriate 3- or 4-celled tip, the lamina with convex sides, entire or occa- 

 sionally with a tooth, almost connate with the leaves on one side of the stem. 

 Branch leaves and underleaves larger, approximate to imbricate, less concave, 

 the uniseriate tips of the leaf-segments longer. Sexual branches and sporophytes 

 not seen. PI. 43. Fig. 20, a, b. 



Habitat: Among Sphagnum, over humus, logs, or the bases of trees in moist 

 mountain forests.

Plants large, green becoming brown, in tufts or mats; stems 5-10 cm long, 

 with leaves to 1.0 mm broad, bi-tripinnately branched, lateral branches 2-3 mm 

 apart, to 8 mm or more long, not becoming flagelliform (?), ventral branches not 

 seen. Line of leaf insertion subtransverse, the upper end bent downward, hook- 

 form. Stem leaves distant to approximate, cucullate-concave, appearing saccate, 

 asymmetric, 0.5 mm long, 0.5-0.8 mm wide at the base, the dorsal margin strongly 

 convex, sometimes semicordate, entire, the ventral margin to only one-fourth as 

 long, with one or two teeth or cilia, obliquely quadrifid to one-third of their 

 length; segments unequal, incurved, triangular from a 4- to 6-celled base, with a
