Abstract
Wunderlichia mirabilis Riedel ex Baker, a Brazilian wind-dispersed tree species, has a disjunct pattern of geographical distribution. This species occurs in ‘campo rupestre’ locations of the Espinhaço Range, andGoiás Mountains, Brazil. The phylogeography of W. mirabilis was reconstructed on the basis of the genetic variability and phylogeny of the nuclear (ITS) and chloroplast (trnL) non-coding spacer regions. AMOVA andMantel analysis revealed for both markers that genetic variability is high within populations and moderate-tohigh among populations. Rates of seed flow are higher than those of pollen flow, and there is a non-significantgenetic x geographic correlation. The spread of Wunderlichia mirabilis probably occurred from Serra do Cabral through other serras in the Espinhaço Range of Minas Gerais and Espírito Santo, in an easterly direction, andthrough Goiás Mountains, Serra da Canastra in Minas Gerais and São Paulo in a westerly movement from the Serra do Cabral, Minas Gerais.
