longis mox in quadratas superne minutas rotundatas subobscuras 
transeuntibus, perichetialibus conformibus, theca in pedunculo elon- 
gato rubro cylindrica pallide fusca, operculo subulato pallido, peristo-

Hab. Japan, Oldham. China, Nan-kong-foo, by the cataract Kiang-si, 
Alexander. 
In compact roundish tufts of a blackish-green colour. In its 
stems and foliage similar to G. erispatum, Hook., but the leaves 
more acute, and the capsule on a longer seta, which gives the 
plant at first sight more the appearance of a Tortula. 
A very few stems, belonging to all appearance to Grimmia apo- 
carpa, L., were intermixed with Stereodon Oldhami.
