membranous. Inner palea nearly as long, delicate, 

 ciliate. 



Rachilla short, flattened and angular, tapering below 

 (see Festuca elatior). 



Caryopsis about 3'5 mm. long, obovate, yellowish 

 brown. 



Fig. 57. Lolium perenne with tj-pioal 

 boat-shaped "seed." a, natural 

 size; 6 and c, x about 8. d, cary- 

 opsis, X 8. The rachilla, in c, is 

 broader upwards and flatter than 

 in Fig. 58. Nobbe. 



Fig. 58. Festuca elatior, var. 

 pratensis. Lettering and sizes 

 as in Fig. 57 : compare the 

 more cylindrical and slender 

 rachilla. Nobbe. 



Although Bromus mollis, Holaus lanatus, &c. occur as impurities 

 they are easily distinguished : the real difficulties are with Festuca 

 elatior and F. pratensis.
