Hab. Andes of Peru, at an elevation of 15,000 feet. 



Eesembles Q. leucophoea, Grev. and may be a local form of that 

 species. It differs, however, thus : the whole plant (the pellucid hair- 

 point of the leaf excepted) is of a reddish-brown color ; the stems are 

 more branched and not clavate; the capsule is less inflated, less 

 emergent, and has a wider mouth and a distinct collum ; teeth of the 

 peristome are not bifid or trifid ; the pedicel is shorter ; leaves are not 

 so spreading and are not cymbiform-concave, neither is their hair- 

 point strongly spinulose-dentate, nor their texture so thick.
