The taxonomy of Calyceraceae, a small family of angiosperms endemic to southern South America and sister of Asteraceae, has recently been revised based on molecular phylogenetic analyses and the evolution of flower morphology. Despite the efforts for precision by those authors, some further nomenclatural adjustments to the classification previously provided are needed: Boopis Juss. is applied as the correct name for the “Pilose group,” and Xiphodesma Pozner & Zijlstra is a new genus name published to accommodate B. anthemoides Juss. In addition, lectotypes are designated for four names: Anomocarpus tenuis Miers, B. anthemoides var. subscandens Speg., B. leucanthema Poepp. ex Less., and B. pusilla Phil.
