Sorghum bicolor (L.) Moench, Methodus 207 (1794).
Fragments of the fruiting inflorescences of grain sorghum are occasionally encountered in imported potpourri. Terminal panicles, which may be up to 60 cm long, have primary, secondary, and even tertiary branches with spikelets arranged in pairs and groups of three at the ends of the branches. Samples in potpourri are commonly 2-10 cm long x 1-6 cm wide. The globular caryopses are 4-8 mm in diameter.
Sorghum bicolor is widely known from cultivation and naturalized in North America. It is a potentially invasive species.
