Abstract
SummaryBethencourtia Choisy (Compositae, Senecioneae) has three species and is dedicated to Jean IV de Béthencourt (1362—ca.1425/1426), who led the first successful military European expedition to conquer the Canary Islands. The botanical history of this Canary Island genus is reviewed, and its nomenclature is revisited. The generitype, Senecio palmensis C.Sm. = B. palmensis (C.Sm.) Choisy, is illustrated (t. 1058). The names S. palmensis and S. hermosae Pit. are lectotypified. Phylogenetic relationships, conservation status, systematics, phytochemistry, and ecogeographical patterns are discussed. A list of the herbarium specimens which have been studied is given.
