A List of the Grasses of Pennsylvania. 
By Tuos. C. Porter. 
At the request of the Pennsylvania Board of Managers for the 
World’s Fair, the author prepared a suite of all the grasses known 
to grow beyond culture within the bounds of the State, and these, 
mounted on card-boards, are now on exhibition in their building 
at Chicago. But, as no way seems to be open, through the parties 
who have the matter in charge, for issuing in pamphlet form for 
distribution a list copied from what 1s printed on the card-boards, 
he has deemed it his right to seek a channel in the pages of the 
BuLLetin for putting on record and making accessible to the pub- 
lic the results of his labors. The list that follows, much enlarged 
by additional notes, is in fact a new work. 
In it, the names of the counties in which the species were col- 
lected are given, with the names of the collectors. Wherever the 
latter are wanting that of the author is to be supposed. All these 
species thus noted can be verified by specimens in the Pennsylva- 
nia Herbarium of Lafayette College, either by a single one, or by 
several from different stations in the same county. 
Besides this, the Flora of Darlington, for Chester county; that 
of Barton, for Philadelphia, and the Catalogues of Dr. George 
Smith, for Delaware; of Dr. I. S. Moyer, for Bucks, and of Pro- 
fessors Dudley and Thurston, for Lackawanna and Luzerne, are 
cited in brackets. 
The numbers attached to the species correspond with those on 
the card-boards of the Chicago exhibit.

Dr. Geo. Smith ; Chester, Porter, (Fl. Cestrica); Philadelphia ;
