Abstract
Abstract Paepalanthus Mart. sect. Diphyomene Ruhland (Eriocaulaceae) is mainly diversified in the savannas of Central Brazil (Cerrado). This is an unusual pattern regarding the highest diversity of Eriocaulaceae in Southeastern Brazil (in the Espinhaco Range). Despite this interesting contrast, the geographic distribution of these species has yet to be explored. The present work aims to detail the geographic distribution of species of Paepalanthus sect. Diphyomene in order to discuss biogeographical patterns. The species are also categorized according to their risk of extinction, based on the IUCN criteria, establishing their conservation status and implications for the conservation of the Cerrado domain. Distribution maps were constructed for each species based on geographical coordinates obtained in the field or from herbarium specimens. All eighteen species occur in the Cerrado domain, with sixteen species exclusive to it, whilst Paepalanthus erectifolius Silveira and P. chiquitensis Herzog also occur ...
