14 CRTPTOGAMIA. 



eanaliculatis usque ad apicem incurvarn tereti-costatis ; capsula ovali 

 microstoma late annulata, collo tumido. 



Hab. Andes of Pern, at an elevation of 15,000 feet. A few stems 

 only found growing among tufts of a Campylopus. 



Stems about 1 -inch high, mostly simple. Leaves from an erect, 

 oblong, amplexicaul base, suddenly wide-spreading, linear-acuminate, 

 carinate-canaliculate, incurved at the apex; margins plain entire; 

 costa terete heavy, extending to the point; areolation minute dense 

 roundish in the upper portion of the leaf. Capsule erect oval, with a 

 conspicuous collum, rather wide-mouthed; annulus large revolute; 

 operculum erect long-rostrate : teeth of the peristome much as in T. 

 crispulum, which the species resembles, but the differently shaped 

 leaves, the distinct collum of the capsule, and presence of an annulus, 

 sufficiently separate it.
