plant, and although there is a resemblance between the two, especially 

 in the inflorescence, the latter is more robust in liabit, has narrower 

 and acuminate-pointed outer glumes, and, so far as examined, but 

 one perfect flowering-glume, which is one-half smaller, with longer 

 and more slender awns. So far as the spikelets are concerned there 

 is a close similarity between Pringle's grass and No. 803 of C. 

 Wright, collected in Western Texas in 1849, and ticketed P.apertum 

 I)y Genh Munro in herb. Bentham, and P. vaginatum by Mr. Buckley 

 in herb. Phila. Acad. I fail to detect the slightest difference between 

 the spikelets of No. 803 of C. Wright and No. 1,362 of Palmer's 

 Mexican collection. Between these and Pringle's grass, or the No. 

 1,360 of Palmer, the diff*erence is more apparent than real, and exists 

 in those characters which are most subject to variation. The. culm 

 is rather stouter, the panicle may be a little longer and is more 

 densely flowered and lighter colored, also the spikelets usually have 

 fewer perfect flowers, but in all other essential points they are alike. 

 Should Pringle's grass prove a good variety of No. 803 of C- Wright, 

 which its habit would seem to indicate, Buckley's name might be 

 adopted to designate it, as it is in a measure descriptive.
