Agropyron pseudorepens Scribn. & Smith. The plants referred to 
this species are undoubtedly indigenous in this region, and appear 
quite different in habit from the European A. repens Beauv., intro- 
duced into the Eastern States. It spreads little by its root- 
stocks as compared with the latter. It has been suggested that 
this is on account of its not oecupying broken land, and that 
when given eultivated ground it would assume the same habit 
as the other. However this may be, our observations of the 
plant lead us to believe that this species should be tried under 
cultivation in the West. Un- 
der favorable conditions this 
grass grows tall and very leafy 
and without the wiry char- 
acter of the much-despised 
“Quack.” —

Agrostis scabra Willd. Forms 
of this well-known grass are 
worthy of more attention in 
this region. In some low mead- 
ows we found it producing

: to be a most excellent one 
where plenty of moisture can be secured. 
Agrostis alba L. In several places more thrifty and luxuriant forms 
of this species were observed than we had ever noticed before. 
This was perhaps owing to the peculiar fertility of the soil. How- 
ever this may be, such forms are worthy of attention and may be 
taken as starting points for improved varieties. 
Bouteloua oligostachya Torr. (See fig.5.) It is hardly necessary to 
speak of this well-known species, with whose merits most people are 
familiar. It is one of the best pasture grasses of the arid plains 
and bench lands of the West, and far excels, in general opinion, the 
true Buffalo-grass, Bulbilis dactyloides (Nutt.) Rafin., which has 
gained much of its credit at the expense of Bouteloua, the two being 
often confused by farmers and ranehmen, Under favorable cireum- 
stances it produces a much larger erop than is usually supposed.
