Engelmann ( '44, p. 104) cites Poa liirsuta,nowE. Jiirsuta, as occur- 

 ring in the state, but no specimens of this have been seen, and it is 

 doubtful whether the species was correctly determined. Higley and 

 Raddin ( '91, p. 144) cite Eragrostis minor, a European species but 

 sparingly introduced into this country. Out of many specimens labeled 

 E. minor in collections which were examined, not one proved to be 

 correctly dctermir.ed ; all Avere small specimens of E. cilianensis. 



50. MELICA L. 

 Melic Grass 



These grasses are perennials with paniculate inflorescence. The 

 spikelets are large, from 7 to 12 mm. long. The glumes and lemmas 

 are thin and papery, with a broad, transparent margin which is con- 

 siderably roughened. The spikelets are 2- to several-flowered, the upper 

 sterile lemmas reduced to club-shaped or hood-like rudiments (Fig. 

 222). The leaf sheaths are closed and the blades are long and narrow 

 with long membranous ligules. 



Glumes nearly equal in length and almost or quite as long as the 2-/lo\vered spike- 

 let; panicle simple or but little branched. M. mutica 



Glumes unequal and considerably shorter than the spikelet, which is usually 3- 

 flowered; panicle compound, the branches spreading. M. nilens
