new Species of Panicum 595 



nizing that they were the same. Among other species described 

 l n this paper Panicum calliphyllum Ashe, we cannot consider to be 

 distinct from P. xanthophysum A. Gray. Panicum Ashei Pearson, 

 evidently named to gratify the author's desire for fame, as this 

 authority is unknown to systematic botanists, is a small form of 

 Panicum commutatum Schultes, but may be worthy of specific 

 rank. In his conception of Panicum nitidum Lam., the author is 

 evidently very much at sea as he refers a western form to that 

 species with this remark : "In the extreme west Panicum nitidum 

 is represented by P. thermite Boland., a rather low, nearly glabrous 

 species." He evidently means Panicum thermale Boland., but any 

 one who has seen Panicum titer mate or even the original descrip- 

 tion, would certainly not consider it glabrous. Panicum Malta- 

 musketense Ashe, 1900, is exactly identical with the type of Pani- 

 cum discolor, co -species veL varietas major Muhl., Desc. 115, 18 17, 

 in the Herbarium of the Philadelphia Academy of Sciences. This 

 name, however, will have to be retained as Muhlenberg's var. 

 major is antedated by Panicum nitidum var. majus Pursh, 1814. 

 Panicum Orangense Ashe, is exactly Panicum lanuginosum Ell., 

 according to a specimen so named by Elliot, in the Herbarium of 

 Columbia University. The first specimen cited under Panicum 

 haemacarpon Ashe, is exactly Panicum Atlanticum Nash, while 

 other material distributed by the author under this name is Pani- 

 cum commonsianum Ashe. Under Panicum Huachucac the mistake 

 is made of applying a local name to a species which, according to 

 the author's statement, extends from Arizona to Iowa and North 

 Carolina, and according to specimens distributed, to New York. 

 We have as yet been unable to separate Panicum mcridionate and 



fih 



original de- 



scriptions or by comparison of typical material. Panicum vicri- 

 dionale may even prove to be unworthy of specific rank. Panicum 

 micropjiyllum Ashe is a doubtful species and the name is invalidated 

 by that of Panicum zisanioidcs, var. microphyllum Doell. ; Mart. 



Fl. Bras. 2 2 : 229. 1877. 



In the same publication * this author publishes another article 

 in which one new species of Panicum, and one species and variety 

 of Andropogon are described, and two new names proposed for
