Karyotypes in Hymenaea L., Guibourtia Benn. and Peltogyne Vog. (Leguminosae, Caesalpinioideae) and its taxonomic implication

Abstract

Hymenaea, Guibourtia and Peltogyne are part of the Hymenaea clade and they present interesting taxonomic challenges and biogeographical patterns. This study presents karyotype data (chromosome numbers and CMA/DAPI banding) from representatives of these genera and some preliminary evidences for an improvement of taxonomy and biodiversity knowledge of the group.
