In species of Scleria, the glumes are disposed distichously in the pistillate spikelets, while the subandrogynous spikelet, staminate spikelet, and androgynous spikelet have one proximal portion with glumes disposed distichously and one distal portion with glumes disposed spirally (Camelbeke, 2002; Ahumada & Vegetti, 2009); this arrangement of the glumes is also characteristic of the bisexual spikelets of Abildgaardia ovata.
