Oryzopsis canadensis (Poir.) Torr. ex Gray Man. 583 (1848) 

 as to name bringing synonym not as to plant. 1 Stipa canadensis 

 Poir. in Lam. Encycl. 7:4")'2 (1806); Hitchc. in Gray Man. ed. 7, 

 123 (1908) — Some time ago Prof. Hitchcock pointed out to me that 

 Stipa canadensis was in reality an Oryzopsis.

Careful study of the genera Sporobolus, Muhlenbergia and Epicam- 

 pes has led me to agree with the conclusion of Rydberg and others that 

 the whole of the group of Sporobolus to which 8. Rickardsonis and 8. 

 brevifolius belong is more correctly placed in Muhlenbergia than in 

 Sporobolus. Furthermore I can find no specific differences between 

 M. squarrosa and M. Rickardsonis and as Vilfa squamosa has 

 priority of place in Trinius's paper I take squarrosa as the name 

 of the collective species that the same name may be used under 

 both codes. 



Muhlenbergia cuspidata (Torr.) Rydb. in Bull. Torr. Bot. CI. 32: 

 599 (1905). Agrostis brevifolia Nutt. Gen. No. Am. PI. 1:44 (1818) 

 not M. brevifolia Scribn. ex Beal Grasses No. Am. 2:254 (1890). 

 Sporobolus cuspidatus (cuspidata) (Torr.) Wood Sedges & Grasses 

 Atlant. Div. U. S. 385 (1871); Scribn. in Bull. Torr. Bot. CI. 10:03 

 (1883). 8. brevifolius (Nutt.) Scribn. in Mem. Torr. Bot. CI. 5:39 

 (1894); Hitchc. in Gray Man. ed. 7, 130 (1908). 



As there is a valid M. brevifolia Scribn. ex Beal S. brevifolius 

 when transferred to Muhlenbergia must become M. cuspidata.

 IIolcus is reapplied to the Sorghum group leaving the IIolcus of authors 

 in need of a name. The oldest generic name, aside from Holcus is 

 Ginannia Bub. which according to the American Code is inadmissible
