gle in T. muralis); and finally, im the dioicous inflorescence. 
The male and female plants grow intermixed and do not dif- 
fer at all in appearance; the perigonial leaves are precisely 
Similar to those of the perichetium, and enclose about 3 an- 
theridia.

This resembles small specimens of 7. levipila Schwgr. in 
habit and essential character ; it forms, however, more lax and 
Spreading patches, and frequently grows intermixed with 
Orihotricha, especially O. diaphanum, from which it is not 
readily distinguished by the eye. The stems are short, 
branched near the base. The leaves are spreading but not 
recurved, shorter than those of T. /evipila, usually less ob- 
tuse, their nerve much less produced and towards the apex of 
the leaf beset with short articulated filaments, as in Tortula 
membranifolia, Hook. ; they are besides more hyaline and brit- 
tle, far more widely areolated, and papillose on their under sur- 
face They do not twist in drying, but {ke margins speedily 
become involute and the apices connivent.
