Ix] “ SEEDS ” 171 
++++ Palea seven-ribbed, smooth. 
Brachypodium pinnatum. 
Brachypodium pinnatum, L., is similar, but the palea 
more open and boat-lke and narrows more suddenly 
above into the smooth awn which is shorter than itself 
(Fig. 77). Length 8—9mm. The caryopsis is, however, 
much more slender than in Agropyrum. 
For distinction from B. sylvaticum, see above. The inner palea 
is ciliate and more delicate than in Agropyrum. 
== Palee rolled round the “seed” which is terete 
and tapering gradually into a stiff awn. 
A Awn longer than the palea. 
Festuca Myurus. 
See also Festuca ovina, Cynosurus, &c., p. 147, and Arundo. 
Festuca Myurus, L. (Fig. 80). 
“Seed” 5—7 mm. without the long (10 mm.) awn, 
tapering and slender (like Nardus), grey or brown. Finely 
mamillate upwards. HRachilla small. 
AA Awn shorter than palea. 
Festuca ovina (var. rubra). 
Nardus stricta. 
Aira flexuosa, Molinia and other moor-grasses occur with these 
narrow-leafed Fescues, but are easily distinguished: Molinia by 
having no awn and being shorter and stouter, and Aira flexuosa by 
the dorsal awn and basal hairs. 
Festuca rubra, L. (Fig. 78). 
“Seed” pale brown with rosy tinge, 3 
without the awn, smooth, or slightly hairy upwards. 
Caryopsis 2—3'5 mm., compressed, with a shallow broad 
5mm. long
