Brachypodium pinnatum, L., is similar, but the palea more open and boat-like and narrows more suddenly above into the smooth awn which is shorter than itself (Fig. [77]). Length 8-9 mm. 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.
≡ ≡ Paleæ rolled round the “seed" which is terete and tapering gradually into a stiff awn.
Δ 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. Rachilla small.
ΔΔ 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.
