Among the exotic genera occasionally cultivated in our fields or gardens 

 may be mentioned Rye {Secale cereale), the Maize or Indian Corn (Zea 

 Mays), and the Feather-grass (Stipa pennata). The latter plant, a native of 

 southern Europe, has by some mistake been inserted in some British Floras 

 as having been found in Westmoreland. 



I. IiEERSIA. LEEHSIA. 



Spikelets loosely panicled, 1-flowered, flat, consisting of only 2 glumes, 

 both of them keeled, without outer empty glumes or inner 2-nerved palea. 

 Stamens in the British species 3, in most exotic ones 6, 2, or 1. 



A small genus, chiefly American, with 2 or 3 of the species spread over 

 the warmer regions of the old world and Austraha. It is doubtful whether 

 in this and other genera of Oryzeee the inner glume should be considered as 

 an anomalous palea, or as the flowering glume vrithout any palea. 



1. Common Iteersia. Leersia oryzoides, Sw. 



(Eng. Bot. Suppl. t. 2908.) 



Stems about 2 feet high, the leaves, especially their sheaths, very rough. 

 Panicle, when fully developed, loosely branched, spreading, 6 or 8 inclies 

 long, but in the British specimens usually much shorter, and partially in- 

 cluded in the sheath of the last leaf. Spikelets numerous, aU turning in one 

 direction, 2 to nearly 3 lines long ; the outer glume rather broad, with 2 

 nerves on each side of the keel ; the inner one much narrower, with 1 faint 

 nerve on each side. 



In wet places, ditches, and marshes, common in North America, extend- 

 ing over a great part of Asia, and more sparingly across central Europe to 

 northern Italy, France, and Denmark. In Britain, only recently discovered 

 iu Hampshire, Sussex, and Surrey. Fl. autumn. 



II. MlZiXUra. MILIUM. 



Spikelets loosely panicled, 1-flowered, without awns. Empty glumes 2, 

 concave, nearly equal. Flowering glume concave, of a firmer texture, hard 

 and shining when in fruit. 



A genus of very few species, but vridely dispersed over the globe ; differ- 

 ing from Panicum chiefly by tlie want of the outermost small glume, front 

 the large tropical genus Paspalum only in inflorescence. 



1. Spreading Milium. Milium effusum, Linn. 

 (Eng. Bot. t. 1106.) 

 A tall, slender Grass, often 4 or 5 feet high, with rather short, flat leaves,
