(16) Stipa porteri Rydb., Torrey Bot. Club 

 Bui. 32:599. 1905. Based on the plant 

 described as S. mongolica Turcz. by 

 Porter and Coulter (Syn. Fl. Colo. 145. 

 1874). [Rocky Mountains, Hall and 

 Harbour 648, error for 646.] 

 This is the species described under the 



name Oryzopsis mongolica (Turcz.) Beal 



(Bot. Gaz. 15: 111. 1890), but that name 



is based on Stipa mongolica Turcz., an 



Asiatic species. 



(13) Stipa pringlei Scribn. in Vasey, U. S. 

 Natl. Herb. Contrib. 3: 54. 1892.

 Stipa pringlei Scribn. ex Beal, Bot. Gaz. 

 15: 112. 1890, as synonym of Oryzopsis 

 pringlei Beal. 

 Oryzopsis erecta Beal, Grasses N. Amer. 2 : 

 230. 1896. Apparently based on O. 

 pringlei Beal, Pringle 1410 being cited, 

 the name changed because of O. pringlei 

 Scribn. ex Beal 1896 (page 226 of the 

 same work). The latter is the same as 

 Stipa virescens H. B. K. of Mexico, not 

 known from the United States. Beal 

 erroneously gives the authority of O. 

 erecta as "(Scribn.) Beal."
