This feature distinguishes the spike from the branching head, called panicle, of the Oats. In the varieties of common Wheat, each spikelet contains three or more flowers arranged one above another on the rachilla, and one or more of the upper flowers are rudimentary. Each fully developed flower, just as in Oats, consists of three stamens and a pistil enclosed by the lemma and palea. The lodicules, like those of the Oat flower, are small inconspicuous scales at the base of pistil and stamens. In Wheat, where the spikelets are broad, the spikelet is only partly enclosed by the glumes. In thresh- ing Wheat the kernel is separated from the bracts â the latter being blown away as chaff. A study of the spikelet shown in Figure 20 will aid the student in un- derstanding the structure of Wheat fl o w e r s and their arrange- ment in the spike- let.
