GRAMINE^ (POACE^), GRASS FAMILY 8l subtending one or more lemmas; in the axil of each lemma is a flower, and each flower consists of a palet (outer perianth), two lodicules (inner perianth), three stamens, and a single pistil. Each stamen has a large anther. The filament {stalk) is attached at the base of the anther, but on account. Fig. 30.—Wheat flower with lemma removed; considerably magnified. of the extreme sagittate nature of the latter, it appears versatile. The ovary is one-celled, one-seeded, bears two styles and two feathery stigmas. There are many deviations from the typical form of spikelet. In Colean- Ihus, the empty glumes are absent; in Nardus, solitary; in Bomalocenchrus, mere rudiments. In some Agrostis species, the palet is rudimentary. It is not always two-keeled, but generally two-nerved. There is a third (posterior) lodicule in some grasses. Although the stamens are as a rule three, there are six in most bamboos and in rice {Oryza). In Streptochceta and Oryza (oc- casionally), there are three styles, and only one in Nardus. 6.
