RUDBECKIA BICOLOR Nutt. Journ. Acad. Phila. 7; 81 (1834). 
This species of more western distribution has been collected in 
eastern Florida. Mr. A. H. Curtiss has found it growing in pine 
barrens near Jacksonville (no. 4759). Some years since he se- 
cured it in fertile fields in Duval county, but distributed it under 
the name of another species (no. 1423). In 1894 Prof. Tracy se- 
cured a remarkably slender form at Biloxi, Mississippi (no. 2896). 
The Blue-eyed Grasses of the eastern United .States (Genus 
Sisyrinchium), 
By EuGeEnE P. BICKNELL. 
(PLATES 263-265). , 
No conclusive answer has yet been given to the old question 
whether there exists more than one East American species of 
Blue-eyed Grass. The common resource of throwing together 
under one name all eastern specimens belonging to the genus is 
easy botany but poor morals. Neither does the recognition of two 
forms or species satisfy the botanical conscience. It would ap- 
pear that only when we take notice of three or more kinds of 
Blue-eyed Grasses do we find ourselves bearing somewhere near 
the truth. It matters little whether these £inds be rated, accord- 
ing to the conceptions of different minds, as species or as forms of 
less signal rank; the pith of the matter lies in this, that each kind 
upholds a certain definite type of individualization which has been 
established in nature. 
I venture to propose a new eastern species in this confused 
genus only on the authority of facts perfectly clear to my mind. 
Nor do I doubt that any student who may approach the subject 
guided by out-of-doors study will reach views not greatly at vari- 
ance with my own. 
Nomenclature. 
An inquiry into the nomenclature of the East American forms 
of Szsyrinchium discloses the unsuspected fact that our common 
Blue-eyed grass of the Atlantic States is without any available
