Microlicia furnensis, a new endemic species from campos rupestres of Capitólio municipality, Minas Gerais state, Brazil, is described and illustrated. The new species is characterized by its cream petals with pale pink blotches at the apex, sessile or subsessile leaves and golden glandular trichomes and short pale trichomes covering the leaves, pedicels, hypanthium and the calyx lobes. It resembles M. confertiflora, M. isophylla and M. flava, the latter also occuring in Capitólio, Minas Gerais state. A list of species of Melastomataceae from the mountains of Capitólio municipality is also provided.

A new endemic species of Microlicia from campos rupestres of the Espinhaço Range is described and illustrated. The new species is characterized by having leaves of different sizes distributed along the branches, petioles 1–2 mm long, leaf blade that are attenuate at the base, with an entire margins, prominent and thickened nerves mainly on the abaxial surface, and an indumentum of short pale, glandular trichomes and sessile golden glands covering the whole plant. It resembles M. avicularis, M. tomentella and M. elegans, which also occur in the Espinhaço Range, in Minas Gerais state.

During a floristic survey of Melastomataceae carried out in Delfinópolis and Capitólio, Minas Gerais State, Brazil, a new species of Fritzschia was found. Fritzschia furnensis has stems peeling in thin, woody flakes, petiole 2–10 mm long, large leaf blades (23–38 × 10–29 mm) and an indumentum of glandular trichomes on the branches, petioles, leaves, bracteoles, pedicels, hypanthia, and sepals. The new species is regarded as endangered (EN) due to a restricted distribution, small populations and the destruction of its habitat.

We described a new species of Phyllanthus currently known from a single fragment of Ombrophilous Dense Forest in the Jequitinhonha Valley, Minas Gerais State, Brazil. Phyllanthus pedicellatus is the second species of the genus with phylloclades found in the Atlantic Forest domain, once mostly Brazilian Phyllanthus with these kinds of specialized branches grow in open vegetation as “campos rupestres” and cerrado. The name is a reference to its remarkable pedicels of pistillate flowers. We present illustrations and photographs of the new species in its habitat, comments on its relationships to other Brazilian Phyllanthus, and its conservation status.

Lychnophora osanyiniana is a new species from “campos rupestres”, a Brazilian savanna ecosystem constantly threatened by agriculture and mining, despite it having a high number of plant species, particularly endemic and microendemic species. The new species was collected from Sítio Serra da Rita, Serra dos Alves, municipality of Itabira, Minas Gerais State, Brazil. The species is recognized by its glomerulate capitulescence with subinvolucral bracts surrounding sessile heads, giving the appearance of a single head. Another distinct character, although it is not exclusive, is an uniseriate pappus, shared by just three species, Lychnophora grisea, L. haplopappa and L. uniflora, of which only L. haplopappa has similar habit, becoming the closest species.

Chrysolaena glandulosa is a new species of Vernonieae (Asteraceae), endemic to the “campos rupestres” of Serra da Canastra National Park and adjacent areas of southwestern Minas Gerais state, Brazil. Chrysolaena glandulosa is characterized by its laxly disposed leaves and lower surface with glandular dots, corolla lobes papillose with glandular dots, and strigose achenes with glandular dots. It is morphologically similar to C. campestris but differs from the latter by presence of glandular dots on the lower surface of the leaves, the ratio between the size of the bracts of the inflorescence and the involucre, and the number of heads and flowers per head. Pollen study confirms that this species belongs to Chrysolaena. A diagnostic key is presented to all Minas Gerais species.

We describe Lippia krenakiana, a new species of Verbenaceae endemic to the campos rupestres of Espinhaço Range in Minas Gerais, Brazil. The species is mainly distinguished by the combination of ovate-deltoid leaf blades and sericeous-villous indument with sessile and pedicellate glandular trichomes. We provide a diagnosis, a morphological comparison with the most similar species, a distribution map, preliminary conservation assessment, and photos of live specimens. Additional notes on Lippia are also provided, as we designate lectotypes for L. glazioviana and L. diamantinensis, and L. violacea is proposed as a new synonym for L. rubella.

Abstract—Fritzschia atropurpurea, an endemic new species from the Serra do Cipó, Espinhaço Range, Minas Gerais state, Brazil, is described and illustrated. This new species can be easily differentiated from its congeners by the combination of the following characters: hirsute-glandular trichomes covering the branches, petioles, leaves, bracteoles, pedicels, hypanthium, sepals, and the medial-apical portion of the right margin of the petals; membranaceous leaves with a dark purple abaxial surface; and long pedicels. Images from scanning electron microscopy, photos of the species in the field, a distribution map, and a key to identify the congeners that occur in the Serra do Cipó are presented. We suggest that if a formal assessment were performed, Fritzschia atropurpurea would probably be categorized as an Endangered (EN) species.

The southeastern Brazilian phytophysiognomy of “campos de altitude” is threatened by the global temperature increase, and because of it, many of its endemic species, such as those of the Asteraceae family, may disappear over the next years. This new species, which occurs in this type of environment, belongs to the genus Heterocondylus (Eupatorieae: Asteraceae), which comprises seven species, mainly with South American distribution. This genus is morphologically variable but all its species share the diagnostic characters, such as: enlarged basal style with variable indumentum, and cypselae with an asymmetrical carpopodium composed of cells with thickened walls. Heterocondylus penninervius is described as a new species from the “campos de altitude” in Serra do Brigadeiro, Araponga municipality, Minas Gerais state, Brazil. The species is recognized by its sessile leaves concentrated in the lower part of the stem, with narrow-elliptical to narrow-lanceolate blade and penninerved leaves, as well as broad capitula with white and pinkish phyllaries. This study provides the description, illustration, taxonomic affinities, flowering and fruiting period and geographic distribution of the species.

Begonia vasconselosiana, a new species of Begonia from Minas Gerais state, Brazil is described. Begonia vasconselosiana is morphologically similar to Begonia lealii Brade with which it is compared. The new species grows in campos rupestres in Atlantic Forest, east of Minas Gerais state, Brazil. Description, diagnosis, etymology, taxonomic comments, illustrations, and conservation status of the new species are provided.

During a floristic study of Chamaecrista in Diamantina plateau, Minas Gerais state, a new species was discovered. Chamaecrista petiolata is here described, illustrated, and compared to its putative closest relative species, C. catapodia and C. monticola. These species are shrubs, the stem-axis exceeding 1.5 m, and show sessile leaves, whereas C. petiolata is a subshrub up to 40 cm alt., with short petiolate leaves. The new species belongs to subsection Absus, which is characterized by glandular trichomes and lack of extrafloral nectaries.
