Acephala group

Groups of cultivars of Brassica oleracea

Mabberley (q.v.) has these groups: Napobrassica Group / Pabularia Group / Acephala Group / Alboglabra Group / Botrytis Group / Capitata Group / Gemmifera Group / Gongylodes Group / Italica Group / Tronchuda Group / Chinensis Group / Japonica Group / Pekinensis Group / Perviridis Group / Rapifera Group

Royal Botanic Gardens Kew[1] has eight groups: Acephala Group (kale, borecole, collards) / Alboglabra Group (Chinese kale, Chinese broccoli, gai laan, kai lan) / Botrytis Group (broccoli, cauliflower, broccoflower, calabrese) / Capitata Group (cabbage, savoy cabbage, red cabbage) / Gemmifera Group (sprouts, Brussels sprouts) / Gongylodes Group (kohlrabi, knol-kohl) / Italica Group (purple sprouting, sprouting broccoli) / Tronchuda Group (Portuguese cabbage, seakale cabbage)

The Acephala group of cultivars or variety for the species Brassica oleracea includes:[2]

The Acephala means "no head"[20] as the plants have leaves with no central head; the opposite arrangement of white cabbage, or Savoy cabbage.

Each cultivar has a different genome owing to mutation,[21] evolution, the ecological niche,[22] and intentional plant-breeding by man.

Mabberley (1997, p.120) has the Acephala group in three sub-groups: kale, borecole, and collards.[23]
