Stachytarpheta is mainly distributed in Brazil, where the knowledge of species richness is still in progress. Here, we describe S. meninii, a new micro‐endemic species from the Diamantina Plateau, Espinhaço Range. It is a shrub that can reach up to 1.8 meters in height, with abundant pedicellate glandular trichomes, viscous, aromatic leaves, inflorescences with oblong‐triangular bracts, and blue corollas, with a tube that is barely exserted from the calyx. The new species has been recorded from two gatherings from the same locality in the municipality of Serro, Minas Gerais state, and can be considered Critically Endangered (CR). Illustrations and a distribution map are provided for the recognition of S. meninii, along with an identification key for species of the genus found in Diamantina Plateau. [ABSTRACT FROM AUTHOR]

Among the Brazilian Stachytarpheta, the small group of species treated as the Stachytarpheta longispicata complex is morphologically recognised by its inflorescences with pedicellate flowers. This character is also present in S. longibracteata and S. rizzoi, two new species herein described based on the morphological species concept. Both species have a restricted distribution in the Cerrado domain, with S. longibracetata found in the Jalapão region (State of Tocantins) and S. rizzoi in the Serra Dourada region (State of Goiás). Detailed diagnosis, morphological comparisons, line drawings, ecological and taxonomic data, provisional conservation status, and a distribution map are provided for each new species. With these findings, we improve the taxonomy of the S. longispicata complex by increasing the number of known species to seven, and providing an identification key for this peculiar group with pedicellate flowers exclusive to the Cerrado.

Verbenaceae includes 32 genera and approximately 800 species distributed mainly in the Neotropical region, especially diversified in Brazil, where the campo rupestre stands out as an important vegetation type for the family. The Itacolomi State Park (ISP) is located in the southeast of the Quadrilátero Ferrífero, Minas Gerais state (MG), Brazil. Vegetation at the Park is composed of campo rupestre and forest remnants among degraded areas. The present research provides a floristic treatment of Verbenaceae in this protected area. Data were obtained from fieldwork and herbarium study. A total of 13 species were recorded: Glandularia phlogiflora, Lantana camara, Lantan fucata, Lantana tiliaefolia, Lantana trifolia, Lippia brasiliensis, Lippia hermannioides, Lippia origanoides, Petrea volubilis, Stachytarpheta cayennensis, Stachytarpheta commutata, Verbena litoralis and Verbena rigida. Among them, six are new records for the ISP. Stachytarpheta glabra, endemic to MG, was found in an area of canga very close to the boundaries of the Park. Additionally, S. viscidula, whose type locality is close to the Park, is proposed as a new synonym for S. commutata, whose type specimen comes from the Park. We provide an identification key, descriptions, photographs and comments on taxonomy, ecology and distribution for each species. [ABSTRACT FROM AUTHOR]
