C0BE6FSIS (Greek, signifying bug hke from the 

 fruit). Compdsita. Tickseed. Annual or perennial 

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

 tives of eastern N. Amer. Lv.s. either opposite or alter- 

 nate : heads pedunculate and radiate ; the broad in- 

 volucre with bracts of two kinds, the outer narrower and 

 greener, receptacle cbaffy ; 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 any garden soil, and bloom freely 

 ■with little care. They are all showy plants.
