New record of Distimake ternifoliolus (Pittier) A.R.Simões & Staples (Convolvulaceae Juss.) from the Brazilian savanna reveals its disjunct distribution pattern

Abstract

We present the first record of Distimake ternifoliolus (Pittier) A.R.Simões & Staples (Convolvulaceae) from the Brazilian savanna (Cerrado). This is a rare species, previously known only from the savannas of the Venezuelan Llanos and the Guianas. We provide a key characters, data on geographic distribution, habitat, conservation status, flowering and fruiting period, updated distribution maps and a key for Distimake Raf. species from Ceará.
