Glumes are bracts subtending the flowers of a sedge or the spikelets of a grass.
In grasses, two bracts known as "glumes" form the lowermost organs of a spikelet (there are usually 2 but 1 is sometimes reduced; or rarely, both are absent). Glumes may be similar in form to the lemmas, the bracts at the base of each floret.
In sedges, by contrast, a glume is a scale at the base of each flower in a spikelet.
