Glumes 2, equal or unequal, the upper enclosing the floret, lower longer, 1—3—5- nerved, acute, acuminate, mucronate, awned, or erose. Lemma cylindrical and fusiform, pubescent, hairy or tubercular-scabrous or both, 3-5-nerved, margins convolute, terminating in a pronounced corona or a reduced rim with or without a coma of longer hairs; lobes conspicuous or small or absent; callus hairy, usually sharply pointed. Awn 0-1-2-geniculate, often very long; column twisted, arista straight or curved. Palea enclosed within lemma, = or < lemma, 0-2-nerved, internerve hairy or glabrous. Flower hermaphrodite. Lodicules 2 or 3, hyaline, nerved or nerveless, glabrous.
