This genus was established in 1803 by Jussieu, upon a plant 
collected by Commerson in the neighbourhood of Buenos Ayres, 
which he named Boopis anthemoides : with this he associated the 
Scabiosa sympaganthera of the ‘ Flora Peruviana,^ which was 
afterwards separated and placed in Calijcera. Richard, in his 
admirable memoir on the Calyceracece, published in 1820, gave 
ample details of the structure of the genus, then reduced to its 
typical species. To this original type are to be added three 
new species recently described by Dr. Philippi, and three others 
which I now contribute; so that the genus will thus comprise
