 local forms of Helianthus. It masses well and gives a variety in 

 color effects. Although the rays are bright- 

 yellow, the disk-florets are greenish-yellow, 

 which affects the tone of the mass. Culti- 

 vation has already produced several very 

 beautiful varieties, and more may be ex- 

 pected.
