EUCHAKIS. 



89 



E. albidum (White Dog's Tooth Violet).— A rare 

 species occasionally met in Iowa and Southward ; its 

 flowers are white, or nearly so, and the foliage is plain, 

 free from the markings that distinguish most of the spe- 

 cies. A variety of this has been discovered at Lake 

 Superior, with yellow flowers. 



E. grandiflorum. — A species occasionally met in 

 the Northwestern States, and in its glory in the North- 

 ern Eocky Mountains. It has larger flowers than E. 

 americanum, but does not differ materially, from a flor- 

 ists' standpoint, in other respects. 



EUCHARIS. 



This genus is of recent cultivation, having been 

 introduced from New Grenada in 1851, where the species 

 are found growing in the marshes in tropical luxuriance. 

 The flowers are remarkable for their purity, beauty and 

 delightful fragrance. As flowers for florists' use, or for 

 greenhouse decoration, they have no equals in the list of 

 bulbs. All the species require the humid atmosphere of 

 the hothouse, the ordinary temperature of the greenhouse 

 being too low for their perfect development. The flow- 

 ers are produced in trusses of from four to ten, accord- 

 ing to the strength of the bulb and the conditions of 

 growth. The impression that generally prevailed soon 

 after their introduction, that they were difficult subjects 

 to manage, was soon dispelled, and their culture became 

 not only common, but very profitable, until the Eucharis 

 insect made its appearance, since which time most grow- 

 ers have become so discouraged, by repeated failures, 

 that they have abandoned their cultivation. But for the 

 ravages of this pest the cultivation of the Eucharis would 

 be attended with as little difficulty as that of almost any 

 popular plant. In fact, but few subjects are more easily 

 managed, water and heat being their chief requisites. 

 Unlike many other plants, they enjoy massing, and to
