NEW AND RARE OHIO PLANTS. 



Walter Fischer. 



Since the last annual report on the State Herbarium was 

 written, ten new plants have been added to the flora of the 

 State. The following is a list of these plants with the names of 

 their first collectors, date and locality of collection and a few 

 remarks as to their occurrence and distribution: 



50a. Marsilea quadrijolia L. Franklin County, W. Fischer, 

 1905. This plant was placed in the botanic garden at the 

 University several years ago and is now spreading in a small 

 stream on the University farm. 



154a. Paiiicum Gattingeri Nash. Cuyahoga County, Otto 

 Hacker, 1901; Washington County, W. A. Kellerman, 1902; 

 Franklin and Warren Counties, W. Fischer, 1905. This Panicum 

 is not so abundant as P. capillare but, is found side by side with 

 the latter and, like it is common throughout the State. 



1546. Panicum cognatum Schultes. Lake County, Otto 

 Hacker, 1901. 



553a. Agave Virginica L. Lawrence County, E. B. Willard, 

 1905. This is a southern plant and was found growing on a 

 hillside near Ironton, probably one of the northernmost limits 

 of its range. 



626a. Salix alba x lucida. Ashtabula and Logan Counties, 

 R. F. Griggs, 1905. 



6266. Salix alba x babylonica? Ashtabula County, R. F.
