Abstract

Stemodiasensu lato is one of the largest genera of the Gratioleae (Plantaginaceae). Recent phylogenetic studies corroborated the paraphyly ofStemodiain its traditional circumscription and suggested the segregation ofS. stellatafrom this genus. This species belongs to a morphologically cohesive group along withS. cipoensis,S. harleyiandS. lobata, all endemic to the Espinhaco Range, eastern Brazil. In this study, we tested the monophyly and interspecific relationships of this group by reconstructing its phylogeny, based on sequences of three cpDNA regions (rps16andtrnLintrons and thetrnL-trnFintergenic spacer), and one nrDNA region (ITS1 spacer), using Maximum parsimony and Bayesian inference. The monophyly of the `S. stellatagroup' was confirmed, and its segregation fromStemodiacorroborated. We proposeLapaeaas a new genus to accommodate its species, with subsequent four new combinations:L. cipoensis,L. harleyi,L. lobata, andL. stellata. Additionally, we describe and illustrateL. rubriflora, a remarkable red-flowered new species, based on morphological and micromorphological evidence. Lastly, a taxonomic revision of the species recognized inLapaeais presented, providing an identification key, photos, descriptions, distribution map and notes on their morphology, geographic distribution, habitat, ecology, and conservation status.Lapaeais restricted to the Espinhaco Range comprising five threatened species, each of them with a narrow distribution and phylogenetic relationships consistent with biogeographic provinces.
