ADDITIONS MADE TO THE CEDAR POINT FLORA 
DURING THE SUMMER OF 1911. 1 
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, June 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 formed 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 26, 1911. 
Dipsacus sylvestris Huds. 
In wave-washed debris along the shore of the Bay about 
two miles south of the Laboratory. O. 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 18, 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.
