The pedicel is relatively thick and is shed with the fruit; a hypogynous perianth scar is seen at the junction of pedicel with base of the fruit.
The style is persistent and remnants of the hypogynous perianth often persist above a very short stipe.
The hypogynous calyx consists of five elongate persistent sepals at the base of a short stipe.
The pedicel is dispersed with fruit, revealing a prominent hypogynous thickened disk and persistent calyx lobes.
alba, is characterized by anthelate or fasciculate inflorescences, hypogynous bristles, and deeply bifid styles.
Although Dichromena has a single capitate inflorescence per culm and Psilocarya had an open paniculate inflorescence, they do have features in common: large spikelets that bear multiple achenes, and achenes that are usually rugulose and without hypogynous bristles.
Also, hypogynous bristles are present in Paniculatae and mostly absent in the other two sections.
While morphological characteristics unique to Pleurostachys include distichous spikelet scales and hypogynous bristles that are flattened and have distal pubescence, there are other characteristics that are also found in Rhynchospora.
In several genera of the Cypereae, there is a tendency to form a hypogynous stalk.
In many genera, there is a tendency to form a hypogynous stalk.
Hypogynous scales, a character considered plesiomorphic in Cyperoideae, are found in Scirpeae, Fuireneae, Eleocharideae, Dulichieae, and Schoeneae but are absent from Abildgaardieae and Cypereae (Goetghebeur, 1998).
The gynophore in Cypereae, formed by the development of the hypogynous stalk, is characterised by a lobed cup that envelops the basal part of the nutlet (Vrijdaghs et al., 2005).
