Aniiido doiia.v L. Sp. PI. 81, 1753, the giant reed, is cultivated for ornament and prob- 

 ably will become established. This is a large herbaceous grass as much as 7 meters tall, with 

 thick knotty rhizomes, flat blades 5 to 7 cm. wide on the main culms, smaller on the branches, 

 and a handsome feathery panicle 30 to 60 cm. long. The conspicuous^ distichous leaves are 

 distributed rather evenly along the culm. 



8. DACTYLIS L. 



Spikelets few-flowered, compressed, finally disarticulating between the florets, nearly 

 sessile in dense one-sided fascicles, borne at the ends of the few branches of a panicle ; glumes 

 unequal, carinate, acute, hispid-ciliate on the keel ; lemmas compressed-keeled, mucronate, 

 5-nerved, ciliate on the keel. Perennials, with flat blades and fascicled spikelets. 



I. Dactylis glomerata L. Sp. PI. 71. 1753. Orchard grass. 



Culms erect, 6 to 120 cm. tall; blades broadly linear; panicle 7 to 15 cm. long, the few 

 stiff branches naked below, contracted after flowering; spikelets crowded in dense i-sided clus- 

 ters at the ends of the branches (fig. 23). 



Escaped from cultivation in pastures and grassland at upper elevations; 

 introduced. Originally described from Europe.
