Morphological examinations reveal new combination Myriopus subulatus in Heliotropiaceae, suggesting key taxonomic clarity.
Based on comparative morphological examinations of specimens available in both physical and digitized herbaria, a new combination is proposed in Myriopus (Heliotropiaceae): Myriopus subulatus (Gardner) J.I.M.Melo. Additionally, Tournefortia lanceolata Fresen. is synonymized under M. subulatus, with its effective lectotypification. Data on the distribution, habitat and reproductive phenology are provided for M. subulatus, as well as taxonomic notes based its morphological characters. Myriopus breviflorus (DC.) Luebert and M. subulatus are morphologically similar, and a key to their identifications is presented together with a list of the specimens examined.
