Summary The genus Xanthosoma has been arbitrarily lectotypified on X. jacquinii Schott, an illegitimate name. Xanthosoma jacquinii Schott may be considered either as validly published in 1832 (an illegitimate renaming of Arum xanthorrhizon and a synonym of X. sagittifolium (L.) Schott), or as not validly published until 1856 (an illegitimate later homonym of X. jacquinii Schott ex Kunth (1841) and a synonym of X. undipes (Koch) Koch. In view of the arbitrary designation of X. jacquinii as “type species” and the confusion surrounding application of the binomial, it is proposed that X. sagittifolium (L.) Schott be accepted as the lectotype species.
