[VOL. 11 



of somewhat smaller cells; stem paraphytia absent. Rhizoids not seen. Line of 

 leaf insertion oblique, the leaves succubous. Leaves imbricate, subsymmetric, to 

 0.6 mm long, to 0.5 mm wide, divided to one-half of their length into four or 

 five segments; segments narrowly triangular, sparsely filiate with paired cilia, 

 the cells averaging 100 X 10 /a, the cuticle striolate-papillose ; lamina lour or five 

 cells high, bearing scattered superficial cilia, its cells averaging 38 X 25 ft.. Under- 

 leaves to 0.4 mm long, 0.3 mm wide, divided to one-half of their length into four 

 or five ciliate segments as in the leaf. Branch leaves and underleaves similar to 

 those of the stem, smaller, without superficial cilia on the lamina. Plants dioicous. 

 Male inflorescence intercalary, near the tip of the stem or branch, the bracts 

 and bracteoles in nine or more series, similar to the leaves and underleaves but 

 larger ; antheridia large, globose, occurring singly. Female inflorescence terminal 

 on the stem or a branch, the bracts and bracteoles in three series, the bracts to 

 1.3 mm long, 1 mm wide, divided to one-half of their length into five or six often 

 branched segments, ciliate as in the leaves; lamina of the bracts and bracteoles 

 eight or nine cells high with numerous superficial cilia. Shoot /sporophyte 

 relationship and sporophyte not seen. Fig. 9, a-d. 



Habitat : In mats on the soil or among other bryophytes.

 Plants small, pale .yellowish-green, in tufts ; stems slender, 3-5 cm long, with 



leaves to 1.2 mm broad, pinnate to irregularly bipinnate, the branches 5-8 mm 

 long ; stems in transverse section 8-10 cells across, the unistratose cortex of 

 smaller cells; stem paraphyllia absent. Rhizoids not seen. Line of leaf insertion 

 oblique, the leaves succubous. Leaves approximate, spreading, subsymmetric, to 

 1.0 mm long, 1.0 mm wide, bisbifid nearly to the base; segments narrowly tri- 

 angular, branched, the cilia long, opposite or whorled, the cells averaging 110 X 

 10 p., the cuticle striolate-papillose; lamina one to a few cells high, the cells 

 averaging 55 X 18 /i. Underleaves smaller, to 1 mm long, 0.7 mm wide, quadrifid 

 to bisbifid to three-fourths of their length, the cilia as in the leaf. Branch leaves 

 and underleaves similar to those of the stem, smaller. Male and female inflores- 

 cences and sporophyte not seen. Fig. 10, a-c.

Plants small, pale yellowish-green, in tufts; stems slender, to 5 cm long, with 

 leaves to 1.2 mm broad, pinnate, the branches to 7 mm long; stems in transverse 

 section 8-10 cells across, the unistratose cortex of slightly smaller cells; stem 

 paraphyllia absent. Rhizoids not seen. Line of leaf insertion oblique, the leaves 

 succubous. Leaves approximate, spreading, subsymmetric, to 1 mm long, 1.3 

 mm wide, quadrifid (bisbifid) to five-sixths of their length, the four segments, 

 branched, nearly equal, triangular, ciliate with long simple or branched cilia, 

 the cells averaging 120 X 10 /«., the cuticle striolate-papillose ; lamina one to a 

 few cells high, the cells averaging 91 X 29 ji. Underleaves smaller, to 0.8 mm 

 long, 0.8 mm wide, quadrifid to near the base, ciliate as in the leaves. Branch 

 leaves and underleaves similar, smaller. Male and female inflorescences and 

 sporophyte not seen. Fig. 11, a-c.
