Helianthus divakicatus, L. 



Our specimens of this species show a wider range of 

 cauline leaf forms than are included in Gray's descrip- 

 tions. They vary from the ovate-lanceolate form, deeply 

 and regularly serrate, to ovate with obtuse or rounded tips, 

 with the serration barely apparent. Specimens collected
