Austin’s types have been examined and compared with 0. 
speciosum. There scarcely seems any necessity for maintaining 
this as distinct from var. polycarpum ; though it antedates the lat- 
_ter. The capsules are numerous, long exserted, and striate at base 
and apex.

depauperate specimens, with spreading leaves, and almost smoot’ — 
calyptras, and differ in aspect from No. 186 S. & L. Muse Bor. —

plants are from the Rocky Mountains, and grew on rocks. |
