986 REPORT OF STATE GEOLOGIST. 



HELIANTHUS L. 



H. ANNUUS L. Common Sunflower. 



This familiar form has escaped from civilization in many parts 

 of the State. In its wild state it is much smaller than under cul- 

 tivation. The species has considerable economic value, and is 

 being quite largely cultivated in some parts of the country. "Its 

 flowers yield honey and a yellow dye; its leaves fodder; its seeds 

 an oil and food; and its stalks a textile fibre" (Britton and 

 Brown). Locally it is somewhat largely cultivated for the oil 

 derived from its seeds. 



Flowering from early in July through the summer. 



Vigo and Monroe (Blatchley); Fayette (Hessler); Clark (Baird 

 and Taylor); Jay, Delaware, Randolph, and Wayne (Phinney); 

 Franklin (Meyncke); Gibson and Posey (Schneck); Jefferson (J. 

 M. Coulter); Noble (Van Gorder); Putnam (MacDougal);- Lake 

 (Hill); Hamilton and Marion (Wilson); Steuben (Bradner). 



H. scaberrimus Ell. Stiff Sunflower. 



(H. rigidus Desf.) 

 This western form seems to have obtained lodgment in the 

 eastern counties. It doubtless first appeared as a migrant, and 

 has since maintained itself, though spreading but slightly. Open 

 places in dry soil. 



Flowers in our range late in August; probably continuing 

 through September. 



Jay, Delaware, Eandolph, and Wayne (Phinney). 



H. occidentalis Riddell. Few-leaved Sunflower. 



Found sparingly in a few counties growing in dry, open places 

 on prairies. 



Flowering season, August and September. 



Cass (Hessler); St. Joseph (Barnes); Vigo (Blatchley); Steuben 

 (Bradner). 



H. microcephalus T. and G. Small Wood Sunflower. 

 (JT. parviflorus Bernh.) 

 Well distributed through the State, and finding its favorite 

 location in moist woods or upon the shaded banks of streams. It 

 also occurs in moist prairies. Apparently more abundant in the 

 southern part of its range. 



Flowers from July through September.
