Treatment

Plectocephalus monocephalus (J. Rémy) Penneck. & Chaura View in CoL , comb. nov.

Basionym:— Centaurea monocephala J. Rémy View in CoL in Gay (1849: 311–312). Type:— CHILE: Biobio Region, Nahuelbuta, “cerros de Nahuelbuta, cerca de Nacimiento”, C. Gay 193 (Holotype P 00703667 !; isotypes P 00703668 !, SGO 000005198 About SGO !) .

Note:—The labels of the types of Centaurea monocephala View in CoL provide no information on the date of collection or any specific locality; the isotype at SGO says “Prov. Concepción, Cordillera Nahuelbuta prope Puren” .

Notes: —This species has not been collected again since the original description, and because the original habitat has been deeply modified in the last century, we suspect that P. monocephalus may be extinct.
