MISSOURI MUHLENBKRGIAS 39 



lemma slender acuminate, hairy-tufted at the base, attenuate 

 into a slender awn 1-5 mm. long. 



Differs from M. soholijera in having shorter, much -branched 

 culms, shorter and narrower leaves, shorter and denser panicles, 

 longer and narrower florets which are awned. Was referred by 

 Vasey to M. syhatica, M. sylvatica, var., M. soholijera, M. soholijera 

 var., and M. Willdenovii. 



Scribner based M. soholijera setigera on Reverchon's 70 and 

 1054, referring to it also his No. 30, but gives neither dates not 

 localities for the type specimens. Many years ago Reverchon sent 

 to Dr. George Vasey of the Department of Agriculture, specimens 

 of Grasses to be determined, and these were numbered from i up, 

 usually marking "Vasey" on his labels. 



The specimens of Muhlenbergia which I am referring to this new 

 species, which he sent to be named, were reported by Vasey under 

 five names, M. sylvatica, M. syhaitca var. — , M. soholijera, M. 

 soholijera var. — , and M. Willdenovii. Believing these to be 

 distinct species and varieties, Reverchon numbered one 1049, 

 another 1050 and so on up to 1054, these being the numbers given 

 to these species and varieties in his MS. list of Texas Plants. 



But the specimens sent to Dr. Vasey with numbers on the labels, 

 and other numbers bearing the same numbers do not agree, and I 

 feel confident that Reverchon used the same numbers over and over. 



I have seen several of Reverchon's No. 70, supposedly part of 

 the No. 70 sent to Vasey, and these are marked M. sylvatica var. 

 — , presumably a MS. name of Vasey's, but these do not appear 

 to be the same as that examined by Scribner. I have also examined 

 two sheets of specimens marked 30 by Reverchon, collected at 

 Ferris, Texas, but these differ from the No. 30 examined by Vasey 

 and Scribner, and cited by Scribner as belonging to his M. soholijera 

 setigera, in being short-awned. These Ferris specimens are named 

 M. soholijera var.- — presumably a MS. name of Vasey's, and the 

 date of collection is stated as 1884 and 1888, while the one cited 

 by Scribner is said to be dated 1885. One of the Ferris specimens 

 is numbered 1665, which makes it apparent that Reverchon sep- 

 arated this variety from M. soholijera, and assigned it a much later 

 number in his MS. list of Texas Plants. 



Having been intimately acquainted with Mr. Reverchon, I 

 learned much about his numbering, the earlier collecting being 

 numbered according to his MS. list, which was arranged in accord-
