A new dwarf Turnera (Turneraceae, Passifloraceae s.l.) from the Brazilian Cerrado

We describe Turnera valeverdensis , a new species from Cerrado grasslands of the iconic region of Vale Verde, Chapada dos Veadeiros, Goiás, Brazil. The new taxon belongs to Turnera series Leiocarpae and can be recognized by its hemicryptophytic and herbaceous habit, reaching 5‐7 cm in height, an obovate leaf blade, rarely elliptic, with a serrated margin and teeth concentrated in the mid-distal portion of the blade, and flowers with lilac petals and purple lines. The new species was found in an area annually visited by tourists and highly studied by researchers, highlighting botanical inattention to small plants. We provide a full taxonomic description, illustrations, photographs, a distribution map, comments on habitat and preliminary conservation status, and a comparison with morphologically similar species. Also, we highlight the need for research involving understory plant species, historically neglected in tropical grasslands and savannas, despite being the layer that harbors the greatest richness of plants in these ecosystems.
