from the Kew Gardens. Of ail tlie races this one seems tlie 

 best adapted to tlie dry prairie regions of the Central United 

 States. 



Festuca ovina, L., Sheep's Fescue. — A small perennial, 

 densely tufted, leaves chiefly radical, very narrow, conduplicate, 

 appearing cylindrical, the upper more or less flattened. Panicle 

 one-sided, short; spikelets, 4-10-fld. Glumes faintly nerved. 

 Dry, hilly pastures, very variable. Of little value, but here 

 mentioned because it is so common and likely to be found. 



Festuca duriuscula, L., Hard Fescue. — Compared Avith the 

 preceding, less densely tufted, taller, larger, sheaths downy. 

 Panicle more open, varying much in color. All intermediate 

 forms can be selected from this to the preceding, of which many 

 consider it a mere variety. 



For dry pastures this seems to be Avorthy of some attention. 



POA, L. 



Spikelets, 2-6-flowered, comjaressed, in loose or close panicles; 

 bunches, 2-nate or in ^-Avhorls. Rachilla jointed between the 

 flowers which are perfect, rarely imperfect. Empty glumes 

 unequal, shorter than the lowest floral one, keeled, acute or 

 obtuse; the lower 1-nerved, the uj^per larger, 3-nerved. Floral 

 glume often Avebbed beloAV, keeled, acute or obtuse, 5, rarely 

 7-nerved, tips hyaline. Palea 2-nerved, ciliate. Lodicules tumid 

 beloAV. Stamens 3. Styles 2, short, terminal, distinct, stigmas 

 feathery. Caryopsis avoid, oblong, grooved, free. Annuals or 

 j^erennials, Ioav or tall, leaA-es flat or condui3licate. About 80 

 species, chiefly in cold or temperate regions, nearly related to the 

 fescues, having shorter and more compressed glumes, Avithout 

 awns.
