Tournefortia kirkii (I.M. Johnston) J.S. Mill. (Boraginaceae): A new combination for a species from Madagascar

A new combination, Tournefortia kirkii, is published, recognizing Tournefortia puberula var. kirkii as a distinct species. An increase in available collections demonstrates that this taxon is more widespread than originally supposed and that it occurs sympatrically with T. puberula while maintaining its distinct morphology, thus meriting recognition as a distinct species.
