The spikelets (fig. 270) are usually enclosed at the base by two empty bracts named glumes (outer or empty, glumes) (), one placed a little above the other; these glumes are succeeded by one or more glumes (flowering glumes) {), arranged distichously on the short rachis, and each of these embraces a single flower (although one or more of them are occasionally empty). Within and facing each flowering glume is a small 2-nerved .glume known as a palea (/>). Within the palea and the flowering glume are two minute scales called lodicules (/), which are regarded as rudimentary perianth-leaves. Stamens (j) are usually 3, but in Rice and Bamboo the number is 6; the anthers are versa- tile and pendulous. Ovary superior {ov), syracarpous, i-celled with a single erect, anatropous ovule; stigm>a {st) usually 2, feathery. Fruit an achene (caryopsis) with the seed closely ad- herent to the thin pericarp, the latter again more or less adherent to the palea and sometimes also to the flowering glume; the outer glumes also in i-flowered spikelets as of Rice (figs. 271, 272) may be more or.
