Dioicous, loosely csespitose or creeping amongst mosses, 

 largish to very large, of a yellowish-green to dark brown colour. 

 Stems (a cross-section shows about 30 cortical cells which are a 

 little larger and darker than the inner, 12 x 15 in diam.), procum- 

 bent, simple or producing one or two short lateral innovant 

 branches, flexuose ; radiculose, rootlets numerous, whitish, clothing 

 the whole of the underside of the stem. Leaves obliquely inserted, 

 horizontal to patent-divergent, bifarious, alternate, distant or 

 contiguous, ovate-acuminate, ovate or more rarely orbicular, 

 margin entire, or erose by gemmae ; texture rather firm, but more 

 delicate than in Mylia Taylori, epidermis smooth, cells large, 

 oblong-quadrate, cell- walls somewhat thin, showing two bands, 

 trigones distinct, darker coloured than the lumen of the cells. 

 Stipules small, often hidden by the rootlets, subulate, bifid to 

 about the \, sinus very narrow, segments acuminate. Bracts 

 oblong-oval, apices often erose. Bracteole free from bracts, subu- 

 late, about 15 cells broad at the base, bifid to about the ^, 

 sinus very narrow, segments acuminate. Perianth oblong-oval, 

 narrower at the mouth and base than the middle, laterally com- 

 pressed, mouth truncate, entire. Capsule roundish-oval ; spores 

 light-brown ; elaters bispiral, about 12 turns of the spiral, reddish- 

 brown. Male stems more slender, ^ terminal or at the middle of 

 the stem, perigonial bracts smaller, more erect, semiamplexicaul, 

 sublobulate, ventricose, antheridia small, spherical. 



Fruits June, July.
