 (15) Stipa porteri Rydb., Bull. Torrey Bot. Club 32: 599. 19C5. 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 the name is based on Stipa mongolica Turcz., an 

 Asiatic species.

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.; 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."
