Content
Description
Annual.

Inflorescence simple, open, not rarely reduced to a single sessile cluster.
Stamens 3;
Notes
Extremely tall or low specimens, and those with many-flowered spikelets, were described as separate species, subsequently reduced to varietal rank (see synonymy). They hardly deserve nomenclatural recognition. A collection from Jappen-Biak, with very slender stems, capillary leaves, inflorescences consisting of 1-4 spikelets only, and 2 involucral bracts the lower of which seemingly continues the stem, answers the description of var. capillaceus , recorded from the Antilles and the Himalaya. Presumably it is merely a depauperated form.
In African specimens the glumes are sometimes strikingly purple-spotted (like in C. sphacelatus).
