Description Spikelets unisexual; staminate spikelets 2-flowered, in pairs on one side of a continuous rachis, one nearly sessile, the other pedicellate; glumes membranaceous, acute; pistillate spikelets sessile, in pairs, consisting of 1 fertile and 1 sterile floret, the latter sometimes developed as a second fertile floret; glumes broad, rounded or emarginate at apex; sterile lemma similar to the fertile, the palea present; style very long and slender, stigmatic along both sides well toward the base.
Note Tall annual, with broad, conspicuously distichous blades, monoecious inflores- cences, the staminate flowers in spike-like racemes, these numerous, forming large spreading panicles (tassels) terminating the stems, the pistillate inflorescences in the axils of the leaves, the spikelets in 8-16 or even as many as 30 rows on a thick- ened, almost woody axis (cob), the whole enclosed in numerous large foliaceous bracts (husks), the-long styles (silk) protruding from the top as a silky mass of threads. Only one species in numerous varieties.
