Plectocephalus chilensis (Bertero ex Hook. & Arn.) G. Don ex Loudon var. brevilobus (DC) Penneck. & Chaura View in CoL , comb. nov. ( Figure 2 View FIGURE 2 ).

Basionym:— Centaurea chilensis Bertero ex Hook. & Arn. var. breviloba Candolle (1837: 575) View in CoL . Type:— CHILE: Coquimbo Region, Coquimbo Province, Coquimbo, 1831/1833, C. Gaudichaud 94 (Lectotype designated here: P 00703636 !; isolectotypes: FI 004939 !, P 00703637 !) .

Note:—This variety is differentiated by smaller leaves with shorter lobules ( Reiche 1905), also the capitulum is sessile, without peduncle, and the flowering branches are densely leaved, whereas in P. chilensis View in CoL the capitulum is pedunculate. This plant has more woody habit rather than P. chilensis View in CoL s.str. We recognize this variety, following Rodríguez et al. (2018).
