Discussion

All the cultivated sorghums are placed in Sorghum bicolor subsp. bicolor. 'Grain sorghums' have short panicles and panicle branches, 'broomcorns' have elongate panicles and panicle branches, and 'sweet sorghums' or 'sorgo' produce an abundance of sweet juice in their stems. For a more detailed treatment, see Harlan and de Wet (1972).
