21-372. DACTYLIS L. 



1. Dactylis glomerata L. Orchard Grass. Map 166. This species has 

 now escaped in all parts of the state, commonly so in limestone areas. It 

 has been sown for both hay and pasture. It affords early pasture and is 

 drought resistant. I think its use is now on the decline. 



Nat. of Eurasia; Newf. to se. Alaska, south w. to Fla. and cent. Calif. 



26-333. PHRAGMITES Trin. 



1. Phragmites communis Trin. Common Reed. Map 167. This grass 

 is found in wet marshes, on mucky borders of lakes and streams, and in 

 springy places in general, hence it is found mostly in our lake area. Here 

 it was once frequent, but it is now rather local on account of drainage. 



N. S. to B. C, southw. to Fla. and Calif. ; also in Mex., W. I. to Chile and 

 Argentina. It is also found in Eurasia, Africa, and Australia. 



28-355. MELICA L. 



Upper surface of leaves generally glabrous and the lower surface generally pubescent; 

 spikelets with 2 fertile florets ; lateral nerves and midrib of the lemmas fading out 

 before reaching the hyaline apex; panicles simple or nearly so 1. M. mutica. 



Upper surface of leaves generally pubescent and the lower surface scabrous or smooth; 

 spikelets with 2 or 3 fertile florets; lateral nerves and midrib of lemmas usually 

 reaching the apex; panicles compound 2. M. nitens. 



1. Melica mutica Walt.* Two-flower Melic. Map 168. This is a local 

 grass in a few of the southern counties, where it is found on the rocky 

 crests or slopes of black oak ridges, and is rarely associated with beech 

 and sugar maple. I have seen this species a good many times but have 

 found only a few tufts here and there and only a few culms to a tuft. 



Md. to Iowa, southw. to Fla. and Tex. 



2. Melica nitens (Scribn.) Nutt. Three-flower Melic. Map 169. This 

 species is very local but usually abundant where found. Its habitat is so 

 varied that it seems worth while to give the habitat in which specimens 



* Plants with spreading pubescent sheaths are Melica mutica f. diffusa (Pursh) 

 Fern. (Rhodora 41: 501. 1939.) I have it from Crawford and Perry Counties.
