MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



[VOL. 11 



Plants small, light yellow-green to olive-green becoming pigmented with 

 brown, forming depressed mats or scattered among other bryophytes; stems 

 slender, prostrate, to 2 cm or more long, with leaves 0.25-0.35 mm broad, regularly 

 pinnate to bipinnate; lateral branches numerous, diverging at a wide angle, 

 0.8-1.3 mm apart, mostly 1.2 cm long, leafy, occasionally becoming flagclliform 

 in the outer part, the ventral intercalary branches frequent, long, flagelliform, 

 the scale-like leaves with rhizoids at the bases; stem cells in longitudinal 

 section elongate, uniformly thin-walled, averaging 96x18 /x, the cortical cells 

 shorter, to 60 n long, stem in transverse section of a unistratose layer of about 

 12 thin-walled cortical cells somewhat larger than the cells of the medulla. 

 Line of leaf insertion transverse. Stem leaves distant to subimbricate, erect to 

 squarrose-incurved in the outer half, quadrifid to within one or two cells of the 

 base; segments subulate, two or three cells broad below and ending in a row 

 of two to four cells, the dorsal segment more or less parallel to the stem, the 

 cells 16-18x16 the walls scarcely thickened, the cuticle verruculose. Stem 

 underleaves distant, divided to near the base into three or four subulate segments, 

 with usually two of the segments shorter than the others, the cells as in the 

 leaf. Branch leaves and underleaves with one segment less. Plants dioicous. 

 Male inflorescence on a short ventral sexual branch, the bracts and bracteoles in 

 six or more series, the bracts larger than the leaves, concave, divided to above 

 the middle into two or three long-pointed segments, the bracteoles plane, bifid. 

 Female inflorescence on a short ventral sexual branch, solitary, one to several 

 on a stem, the bracts and bracteoles ovate, those of the inner series to one-sixth 

 divided into two or three ciliate laciniae, the lateral margins obscurely ciliate, 

 the cells averaging 64x24 /x, thin-walled, the cuticle verruculose. Perianth to 

 5 mm long, three-keeled and contracted above, the mouth ciliate with the cilia 

 to six cells long. Sporophytes not seen. PI. 49. Fig. 1, a-m.
