Tripsacum image
Plants perennial; monoecious, staminate and pistillate spikelets evidently distinct, located in the same inflorescences, pistillate spikelets below the staminate spikelets. Culms 0.7-5 m. Leaves not aromatic; sheaths open; ligules membranous, erose to ciliate. Inflorescences terminal and axillary, panicles of 1-several subdigitate to racemose rames; rames with pistillate spikelets proximally and staminate spikelets distally; disarticulation in the rames, beneath the pistillate spikelets and at the base of the staminate portions. Pistillate spikelets exposed, solitary, embedded in the indurate rame axes; lower glumes coriaceous, closing the hollows in the rachises and concealing the florets; upper glumes similar but smaller; lower florets sterile; upper florets pistillate; lemmas and paleas hyaline, unawned; styles 2, not fused. Staminate spikelets paired, both sessile or both subsessile, or 1 sessile and the other pedicellate; glumes coriaceous, chartaceous, or membranous; lemmas and paleas hyaline, unawned. Pedicels (when present) not fused to the rame axes. x = 9. The origin of the name is unknown.
