The nomenclature of <i>Sorghum bicolor</i> (L.) Moench (<i>Gramineae</i>)

Abstract

The currently used subspecific names for the annual wild and weedy relatives of domesticated sorghum either lack valid publication or have not had their priority established over competing names of equivalent priority. These problems are resolved with valid publication of the new combination Sorghum bicolor subsp. verticilliflorum and establishment of its priority and that of S. bicolor subsp. drummondii over competing synonyms.
