Black-eyed peas are a commercial cowpea class, not every pea or bean
USDA defines Blackeye beans as cowpeas of the Blackeye variety and the inspection handbook also treats Browneye and Violeteye or Pinkeye types within that class. Codex CXS 171-1989 separately identifies cowpeas as Vigna unguiculata among dry pulses. Atlas therefore retains botanical identity, commercial type and colour pattern instead of merging Blackeye lots with Phaseolus beans, Pisum peas, other cowpea classes or a generic legume label.
