SPHiERIACEiE IMPERFECTS COGNITS. 
Under this heading in Saccardo’s Sylloge, he enumerates no less 
than 420 species of which the fructification was unknown to him. 
Whether this list might not with little trouble have been consider- 
ably reduced, we will not stay to enquire. Suffice it to say that we 
have taken the first 89 species, belonging to the Composite, and 
subjected them to examination, with the following result. 
We are indebted to Mr. W. C. Stevenson, of Philadelphia, for 
the determination of some of the species in the Schweinitzian 
Herbarium, for which we had not access to authentic specimens. 
The numbers at the left refer to the corresponding numbers in the 
“ Sylloge.”
