different seasons of the year, and the flowers are a hill deep crimson-

of this extensive and difficult family. I place the present species, 
with some confidence, in Buellia, because of its gr^ sum an y 
in habit and fiow^ers to the Buellia hracteata of i. Ir. 
New Holland, as figured by Endlicher in his valuable Icouo- 
graphia’. Erom that, however, our present 
recognized by the different form of the corolla, and by its glabrous 
stem and leaves. .
