 Muhlenbergia diffusa Schreb. Besch. Graes. 2: 143, t. 51 (1810). This is 

 often quoted as "1772-79"; but the title-page and Pritzel's Thesaurus agree 

 on the date 1810. The title-page of the first part (pp. 1-154, pll. I-XXI) is 

 dated 1769; but the plates are dated variously from 1766-1768. The second 

 part, in the copy I possess, has no separate title-page (pp. 1-88, pll. XXII-XL). 

 This is said by Pritzel to have been issued 1772-1779. It was apparently 

 issued in three parts, the signatures for pp. 1-20 reading "II Th.;" for pp. 

 21-56, "II Th., 2 Ausg.;" for pp. 57-88, "II Th., 3 Ausg." The dates of the 

 plates vary from 1760-1778. The third part is designated on the title-page as 

 "Zweiter Theil", and seems to be a continuation after a long interruption (pp. 

 89-160, pll. XLI-LIV). Riley, Chase, Pawnee, Saline.
