now regarded as a monotypic genus consisting of S. dura Beauv. ; 

 Smith (Engl. Fl. i: 119. 1824) regarded it as a Glyceria; and 

 Kunth (Rev. Gram, i: 129. 1829) very tardily recognized 

 the relationship to Festuca by placing it in that genus. 



The genus Sderopoa was finally established by Grisebach 

 (Spic. Fl. Rumel. 2: 431. 1845) and was made to include but 

 the one species S. rigida. Since that time various concepts of 

 the genus have prevailed. Parlatore in 1848 recognized seven 

 Italian species. Boissier in 1884 recognized seven species in 

 his Flora Orientalis. Twelve binomials are given under Sderopoa 

 in the Index Kewensis. Hackel (in Engler & Prantl, Nat. 

 Pflanzenfam. 2: 2, 75. 1887) states that there are "2 Arten," 

 and names 5'. rigida. What he regards as the second one cannot 

 be conjectured with certainty, although of the various species 

 that have been proposed 5. Hemipoa (Delile) Pari. (Fl. Ital. 

 1:472. 1848), a native of Sicily, would seem to have perhaps 

 the best claim to validity. 



I am under obligation to Dr. J. H. Barnhart for compiling 

 and verifying the bibliography of Sderopoa, and. to Prof. A. S. 

 Hitchcock, Dr. J. K. Small, Mr. J. F. Macbride and Prof. 

 Matthew Fowlds for their information regarding herbarium 

 specimens. Duplicates of my own collection have been deposited 

 in each of the three large herbaria named above.
