 810. ROUGH OR WOODLAND SUNFLOWER 



HELIANTHUS DIVARICATUS L. 



Not rare ; noted on shore in front of the Palmer House grounds. 

 Leaved out well and growing finely May 10, 1901. 



811. HAIRY SUNFLOWER 



HELIANTHUS MOLLIS Lam. 



Found on a bank on the east side of Lost Lake, also in open 

 places between the lakes. Noted in flower September 19, 1900. 

 Common on the bank back of Green's field at the beginning of Lost 

 Lake outlet, growing in the dry sandy soil. 



812. PALE-LEAVED WOOD SUNFLOWER 



HELIANTHUS STRUMOSUS L. 



Occasional in dry places west of the lake.

814. WING-STEM 



RIDAN ALTERNIFOLIUS (L.) Britton 



Scattered in fair abundance on the east side of the lake back

 their sides. 



815. TALL TICKSEED 



COREOPSIS TRIPTERIS L. 



Found south along the railroad; up well and leaved out finely

 the edges of thickets. The heads are not especially showy, com-

 susans and the like are in full sway. Unlike most flowers of the 

 sunflower group, those of this plant are decidedly fragrant. 



816. STIFF TICKSEED 



COREOPSIS PALMATA Nutt. 



East side of Lost Lake outlet, on a dry sandhill. Up well May 

 12, south along the railroad. Not very common ; it seems to be con-
