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 vdth the names of 
their first collectors, date and locality of collection and a few 
remarks as to their occurrence and distribution; 
50a. Marsilea quadrifolia 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. Panicuni Gattingeri Nash. Cuyahoga County, Otto 
Hacker, 1901; Washington County, W. A. Kellerman, 1902;

is not so abundant as P. capillare but, is found side by side with 
the latter and, like it is common throughout the State.

Hacker, 1901. 
553a. Agave Virginica L. Lawrence County, E. B. Willard,
