ECHINOCA CTUS—ECHINOPSIS. 



'93 



much given to the production of aerial roots ; 

 flowers equal in size to those of C. grandiflorus ; 

 orange and pure white. 

 C. triangularis. — Mexico. Stems stout and tri- 

 angular ; flowers 1 foot in length and the same 



across ; sepals narrow and green, petals broader ; 

 pure white, with yellow stamens. 

 E. Echinocereus. — Species are not sufficiently distinct 

 to form a genius, and the best of them are included 

 under the heading Cereus. 



ECHTNOCACTUS. 



Species of what is known as the Hedge-hog Thistle are, by their habit and stem 

 character, worthy of inclusion in all collections. They thrive best in gentle heat. The 

 majority are natives of Mexico.

ECHINOPSIS. 



In addition to being somewhat hardier, this section differs from Echinocactuses 

 in the formation of the flowers, which are remarkable for their great size, length of 

 tube and beauty. They are borne, generally, on small and somewhat stumpy stems. 

 When properly treated the plants flower profusely. They should be kept in a root- 

 bound state, also free from offsets, and must be carefully rested during the winter, 

 receiving little or no water, especially if comparatively low temperatures are main- 

 tained. All are easy of propagation, and none need be grafted on other Cactuses, as
