which they promptly bee one erect or send up new culms. In spite 

 of the coarseness of the sterns stock oat the grass down very close 

 but the hard knotty base soon sends up new culms. In fact this is 

 a grass that is very hard to defeat in its proper site. Its chief 

 limitation is that it requires considerable moisture. In the nur- 

 sery it produces at least two excellent crops of hay and seed. 



♦ Muhlcnbergia lon g il igula , Slender Bull Grass, is a tall 

 bunch grass closely resembling H« emers leyi . It does not have awns 

 on the spikelets and the lower sheaths are not compressed-keeled. 

 This is a good forage grass from western Texas to southern Arizona 

 and Mexico. 



Huhl enbergig. subpatens. Beardless Bull Grass. Hitchcock's 

 Manual makes this species* a 'synonym of M, emersleyi. Field obser- 

 vations, however, indicate that it a well defined species which fre- 

 quently hybridizes with II. emersleyi » A form in the &os Cabezos 

 Mountains of southern Arizona is less than two feet high and may 

 prove to be distinct even from II, s ubpatons . This has long, hard 

 scaly rhizomes and almost spicatc paniclcsT Judging from the way 

 it is browsed it is a highly palatable grass. 



♦ Muhlenbcrgia glau ca, Glaucus Muhly, occurs in the mountains 

 in the southern part of ^egion Eight and in Old Mexico. It is con- 

 fined to quite steep, rather dry, loose rocky slopes. It is a very 

 leafy, rather loosely bunched grass with numerous rhizomes and looks 

 like a very promising grass for propagation and erosion control work. 



*!■ luhl onb or g i a polyoaulis ranges from western Texas to south- 

 ern Arizona and central Mexico. It is a perennial from a rather 

 loose crown* The culms are numerous and leafy. The entire grass 

 is usually not more than a foot and a half high. This grass has 

 probably been driven back into the fastnesses of the steep rocky 

 hills because of its high palatability, 



* Muhlenbcrg ia moriticola, Mesa Muhly, is a perennial from a 

 rather loosely tufted base, the culms being numerous and quite 

 leafy. The panicles resemble those of M. polycaulis. It ranges 

 from western Texas to Arizona, and. central Mexico and is quite simi- 

 lar in the sites in which it grows to that species, being confined 

 by stern necesciry, hiding itself away in rough, rocky places whore 

 stock cannot reach it. 



*Muh lenb orgia montana, Mountain Muhly. In the southern part 

 of Arizona and Hew Mexico this species is scarce, if not rare. In 

 the Flagstaff section, however, and along the Mogollon mesa it is
