Abstract

A new species of Convolvulaceae, Bonamia minima A.L.C. Moreira & Faria, is described and illustrated based on a collection made in 2012 from a region of high diversity in the Central Plateau of Brazil, in campo rupestre. The new species is most similar to B. austinii A.L.C.Moreira & Sim.-Bianch., the only congener with which it shares the combination of sericeous indumentum and bifurcate trichomes on the leaves. It can be distinguished from this species mainly by characteristics of the gynoecium, presenting a completely glabrous ovary. Details of its habitat, distribution, phenology, conservation status, and micromorphological aspects of the leaf and pollen are provided, along with a comparison to the most similar species.
