angle of 45°, innermost large, 4 times larger than the stem leaves, 

 quadrate-oblong, subcordate at the base, bifid to about the ^th, 

 segments obtusate, rarely subacute, outer ones gradually becoming 

 smaller and changing into stem leaves. Perianth half hidden by 

 the bracts, subcompressed, very obtusely trigonous (third angle 

 postical), antical deeply unisulcate, mouth small, denticulate or 

 setulose, setie 1-4 cells long. Capsule brown, oblong- globose, 

 valves delicate, composed of two layers of cells. Elaters reddish- 

 brown, bispiral. Spores pale brown. 



Androecia on separate stems growing with the $, simply fur- 

 cate, not repeatedly innovantly dichotomous as in the $ ; perigonial 

 bracts several, terminal or along the stem, slightly imbricate, 

 swollen at the base, bifid to about the -J^rd, segments obtuse, 

 antheridia solitary, oval. 



Fruits May, June.

Obs. — " In size this resembles CepJialozia dkaricaia, but its 

 true alliance is with Jung, minuta, of which it might be accounted 

 a microscopic form. Owing to the rigid chitinous texture of 

 Jung, ntgriocarpa, the stems and even perianths decay very slowly.
