Sorghum
Family: Poaceae	FNA Gleason & Cronquist Resources Mary E. Barkworth. Flora of North America Plants annual or perennial. Culms 50-500+ cm; internodes solid. Leaves not aromatic, basal and cauline; auricles absent; ligules membranous and ciliate or of hairs; blades usually flat. Inflorescences terminal, panicles with evident rachises; primary branches whorled, compound, the ultimate units rames; rames with most spikelets in heterogamous sessile-pedicellate spikelet pairs, terminal spikelet unit on each rame usually a triplet of 1 sessile and 2 pedicellate spikelets, rame axes without a translucent median line; disarticulation in the rames below the sessile spikelets, sometimes also below the pedicellate spikelets (cultivated taxa not or only tardily disarticulating). Sessile spikelets dorsally compressed, calluses blunt or pointed; lower glumes dorsally compressed and rounded basally, 2-keeled or winged distally, 5-15-veined, usually unawned; upper glumes 2-keeled, sometimes awned; lower florets reduced to hyaline lemmas; upper florets pistillate or bisexual, lemmas hyaline, sometimes awned. Pedicels slender, neither appressed nor fused to the rame axes. Pedicellate spikelets staminate or sterile, well-developed, often subequal to the sessile spikelets in size. x = 10. Name from the Italian word for the plant, sorgho. Vascular plants of NE US and adjacent Canada Spikelets in pairs, or at the ends of the branches in threes, numerous, dorsally compressed, forming a large, branching panicle that in wild- adapted plants disarticulates at maturity into joints bearing a single pair (or trio) of spikelets; one spikelet of each pair sessile and perfect, the other pedicellate and staminate or neuter; glumes indurate, about equal; lemmas hyaline, the palea ±reduced, both sorts of spikelets typically with a lower empty lemma and an upper floriferous one; upper lemma of the fertile spikelet usually with a geniculate and twisted, readily deciduous dorsal awn. 20, e.
