C0RE6PSIS (Greek, signifying Img-Hke, from the 

 fruit). Conrpdsito!. Tickseed. Annual or perennial 

 herbs, flowering in summer and autumn. Nearly all na- 

 tives of eastern N. Amer. Lvs. either opposite or alter- 

 nate : heads pedunculate and radiate ; the broad in- 

 volucre with bracts of two kinds, the outernarrower and 

 greener, receptacle chaffy ; rays very showy, yellow 

 particolored or rarely rose, neutral : disk fls. yellow, 

 brown or dark. The genus differs from Bidens only in 

 the broad, flat and winged akenes, with short or obso- 

 lete pappus. Many of the species are in the trade under 

 the name Calliopsis. All the kinds are of easiest cul- 

 ture. The perennials are hardy border plants The an 

 nuals are raised in an\ gaiden soil and bloom fitfl} 

 with little care The\ aie all showy plants
