In Poaceae, the grass family, a spikelet consists of two (or sometimes fewer) bracts at the base, called glumes, followed by one or more florets. A floret consists of the flower surrounded by two bracts, one external—the lemma—and one internal—the palea. The perianth is reduced to two scales, called lodicules, that expand and contract to spread the lemma and palea; these are generally interpreted to be modified sepals. WebWhen the supply of sugars from the leaves exceeds the demand for new leaf development and growth, certain grass species may develop a rhizome. A rhizome is a segmented, subterranean, modified stem arising …
