Plants small, filamentous, in light yellow-green tufts or mats; stems slender, 

 3^ cm long, more or less radial, often erect, densely leafy above, regularly 

 pinnate to bi- or tripinnate, the lateral branches long, the half-leaf bifid, ventral 

 branches occasional, leafy throughout or with smaller leaves for some distance, 

 then becoming densely leafy above; stems in transverse section with a cortical 

 layer of 18 or 12 large cells surrounding a medulla of smaller cells. Rhizoids 

 from small cells of the bases of the underleaves and the base of the female 

 branch. Line of leaf insertion transverse. Stem leaves distant to approximate, 

 rectangular to cuneate in outline, divided to two-thirds or four-fifths of their 

 length into mostly four (sometimes five or six) segments, the lamina two cells 

 high at the margins, two or three cells high between or one cell high at the 

 margins and two or three cells high between, usually eight (ten or twelve) cells 

 wide, the cells quadrate to rectangular, thin walled; segments uniseriate, four 

 or five cells long, sometimes curved, the cells of the lower part averaging 

 73x21 p.. LJnderleaves similar, the segments four or five cells long, the lamina 

 mostly two cells high throughout, eight (ten or twelve) cells wide. Branch leaves 

 and underleaves with one or two segment less. Plants dioicous. Female inflores- 

 cence terminal on a leafy branch, more rarely on a short ventral branch, the 

 bracts and bracteoles in four series, the outermost series quadrifid to one-half of 

 their length, the intermediate series divided to one-third of their length into 

 four segments with a few short cilia on the margins, the innermost series divided 

 to one-half of their length, the segments undivided. Perianth 4-5 mm long, 

 cylindrical to fusiform, with three rounded keels above, the mouth contracted, 

 long ciliate with simple cilia. Capsule long ovoid, brown with the characteristic 

 brown thickenings. Seta with an outer row of 16 large cells surrounding many 

 smaller cells. Male inflorescence not seen. PI. 53. Fig. 5, a-g. 



Habitat: Over soil, banks, logs, tree bases, and other bryophytes, in 

 shaded areas.
