COMPOSITE 



THE FLOWER HEADS: few or solitary, two inches broad, 

 borne on short hairy peduncles; involucre hemispheric; 

 its bracts lanceolate or ovate-lanceolate, the outer ones 

 spreading; rays eight to fifteen. 



THE FRUIT: achenes, the pappus consists of deciduous 

 chaffy scales. 



This Wild Sunflower is a copy, on a much slenderer and 

 smaller scale, of the cultivated Sunflower. The flat centre 

 or disk is brown although more yellow-brown than purple- 

 brown, and the oblong, petal-like rays are yellow. On 

 account of its slightness, this is the more graceful plant.
