COREOPSIS. 



[The name is from Greek words, signifying a bug and resemblance. Its fruit 

 is convex on one side, and concave on the other ; it has a membranous margin, 

 and it has two little horns at the end which gives it very much the appearance of 

 some insect.] 



The genus has been divided, and C. tinctoria and its 

 varieties are now classed in the genus Calliopsis, but as 

 they are generally known as Coreopsis, I shall consider 

 them under this head. The genus includes both perennials 

 and annuals. The perennials are hardy border-plants, with 

 yellow flowers and most of them quite showy. The most 

 desirable are C. tenuifolia, with very delicate pinnated foli- 

 age, about one and one-half foot high ; C. lanceolata with 

 lance-shaped and large flowers ; G. latifolia, C. verticilla- 

 ta, C. tripteris, and others, all continuing long in bloom. 

 Propagated by dividing the roots. The following are an- 

 nuals. 



Coreopsis Drtimmoildii is a fine bedding plant, where a 

 mass of brilliant yellow flowers are wanted ; the flowers 

 being very large, and continuing in bloom most of the 

 season. It is about one and one-half foot high. 



C. Coronaria has flowers of a paler yellow, each petal 



or ray is marked or penciled with brown at the base. 



Most of the genus of Coreopsis are natives of N. America. 



C. Drummondi, was discovered by Mr. Drummond, and 



named after him. 



C. tinctoria was introduced by Nutall, who found it in 

 great profusion in Missouri and other southwestern States.
