Panicum sect. Antidotalia

Freckmann & Lelong
Treatment appears in FNA Volume 25. Treatment on page 482.

Plants perennial; rhizomatous. Culms robust, lignified, branching at the middle nodes. Ligules membranous, ciliate, cilia longer than the membranous base. Panicles pyramidal, more or less lax, with many spikelets. Spikelets ellipsoid to ovoid. Lower glumes to 1/2 as long as the spikelets, 1-5-veined; upper glumes and lower lemmas 7-11-veined; lower florets staminate; upper florets smooth, shiny, x = 9.

Discussion

In Panicum sect. Antidotalia, the culms become almost woody at maturity; even a hammer blow fails to flatten them.
