Notes
The hypogynous bristles, when reduced to a small 6-toothed cup, were called by Nees a disc. Kunth supposed that by “disc” Nees understood the obpyramidal 3- (or several-) toothed gynophore of Scleria and of many species of Fimbristylis. But the two discs are not homologous: the stamens are entirely within the “disc” of Eleocharis, entirely without the disc of Fimbristylis .
