Lake Maxinknckee, Physical and Biological Survey 439 



In addition to the rudbeckias above mentioned another, prob- 

 ably subtomentosa, grew along the southwest shore of the lake 

 between Murray's and Farrar's, but it was seen on a hurried trip 

 in that region and no herbarium specimens were secured. 



805. GRAY-HEADED CONE-FLOWER 



RATIBIDA PINNATA (Vent.) Barnhart 



Not common; noted along the railroad east of the depot and 

 near the lake September 29, 1900. Although this species is ap- 

 parently indigenous it has a habit in many parts of the country 

 of growing usually on roadsides, as if introduced. 



806. PURPLE CONE-FLOWER 



ECHINACEA PURPUREA (L.) Moench 



Not common ; only one patch found on a hill some distance down 

 the outlet in 1909. This was not found during the preceding years 

 of the survey and had somewhat the appearance of having arisen 

 recently from perhaps a single stray seed of a few years before; 

 one plant could easily have been the parent of the entire colony. 

 Although the leaves are coarse and homely, giving a weed-like as- 

 pect to the plant before blooming, the flower-head, with its long 

 drooping purple rays and spine-like orange-colored disk flowers, is 

 a striking object. 



807. COMMON SUNFLOWER 



HELIANTHUS ANNUUS L. 



An occasional escape from cultivation near Culver. 



808. FEW-LEAVED SUNFLOWER 



HELIANTHUS OCCIDENTALS Riddell 



Not particularly common; a few plants were found scattered 

 along the hill east of Lost Lake outlet, near Green's field, and a 

 few south along the railroad. Leaved out well by May 12, 1901. 

 It grows in dry sandy soil. 



809. TALL OR GIANT WILD SUNFLOWER 



HELIANTHUS GIGANTEUS L. 



Found by Lakeview Hotel in the sedgy flat September 29, 1900. 

 Rather common in moist places in rich ground. Common between 

 Culver and Hibbard.
