ADDITIONS MADE TO THE CEDAR POINT FLORA 

 DURING THE SUMMER OF 1911.i 



E. L. Fullmer. 



Additions made to the Cedar Point Flora during the summer 

 of 1911: 



Lithospermum arvense L. 



At the edge of a recent lagoon near the Breakwater, and 

 growing in the Juncus association, Jmie 28, 1910. O. E. 

 Jennings. Seed very likely reached this place by means of 

 water transportation. 



Cycloloma atriplicifolium (Spreng.) Coult. 



On sandy banks of newly fonned lagoons near the Break- 

 water. O. E. Jennings, June 26, 1911. Prof. Moseley had 

 known of the occurrence of this species here in previous years 

 but evidently had not reported it. Probably introduced by 

 water-transportation frojm the upper Great Lake region. 



Archangelica atropurpurea (L.) Hoffm. 



In marshy vegetation surrounding a lagoon near the 

 Breakwater. O. E. Jennings, June 2G, 1911. 



Dipsacus sylvestris Huds. 



In wave-washed debris along the shore of the Bay about 

 two miles south of the Laboratorv. 0. E. Jennings, July 

 13, 1911. 



Triadenum virginicum (L.) Raf. 



Around the shore of the Lily Pond, northwest of the 

 Breakers Hotel. O. E. Jennings, July IS, 1911. The sudden 

 appearance of this species around the pond in a narrow strip 

 of vegetation, which had been thoroughly surveyed the 

 year before, suggests that birds must have brought in the 

 seeds. 



Miss Blanche McAvoy did some work upon the Grasses and 

 Sedges of Cedar Point and as a result of her work the following 

 three species are added to the list: 



Panicum ovale Ell. June 23, 1911. 

 Panicum villosissimum Nash. June 23, 1911. 

 Scirpus occidentalis (Wats.) Chase. June 27, 1911. 



1. Presented at the meeting of the Ohio Acad, of Sci., Dec. 1, 1911.
