Plate 260a 



An erect, perennial herb, 1 to 2 feet high, stems slender, striate, smooth 

 or more or less pubescent, especially below. Leaves smooth or somewhat 

 hairy, opposite; the basal and lower stem leaves spatulate or oblong, entire, 

 sometimes with a pair of lateral lobes, 2 to 6 inches long, on slender petioles; 

 upper stem leaves few, lanceolate to oblong, nearly sessile. Heads of 

 flowers usually few, i| to 2\ inches broad, showy, bright yellow, borne on 

 long, slender peduncles often 8 to 12 inches long. Involucres rather flat- 

 tened, their bracts ovate-lanceolate, in two series, the outer narrower than 

 the inner but nearly as long. Ray flowers six to ten in number, wedge-

 the darker yellow disk. Achenes oblong, winged on the edges, with two 

 short teeth projecting from the summit, giving it somewhat the appearance 

 of a bug. It is from this character of the achene that the generic name 

 Coreopsis, meaning " buglike," is derived.
