Specimens of this fine plant, no less remarkable for the large 
size of its flowers than for the deeply-lobed ribs of the stem, 
were purchased of Mr. Bridges on his return from Bolivia, where 
he had gathered them and other fine species of Cactacee then r 
first known in our gardens, in 1844. In 1846, the individual — 
which blossomed, and which is here represented, produced purple 
flowers ; that which bloomed the following year (1547) bore 
white ones. The latter we look upon as identical with the 
Echinopsis cristata of Salm-Dyck. The genus Hchinopsis, if 
genus it really be, is placed in a distinct tribe, Cereasiree, from 
Echinocactus, which is in Echinocactee : the former beng cha- 2
