Two new micro-endemic species of Eriocaulaceae are described from the Campos Rupestres of Serra Nova State Park, a conservation unit located in the Espinhaço Range in northern Minas Gerais state, Brazil. Herein we provide descriptions, illustrations, photographs and maps, together with notes on morphology, distribution, phenology, taxonomy, and conservation. Paepalanthus ferrugineus is distinguished mainly by the reddish-brown involucral bracts, surpassing the floral disc, with the apex attenuate and tufted adaxially, tufted sepals and hairy petals. Syngonanthus polyaxis is easily differentiated by the inflorescence architecture with three morphologically distinct axial parts. Both species are considered Critically Endangered according to the IUCN Red List criteria.

Hibiscus L. is one of the largest genera of Malvaceae, Southeast Brazil has six endemic species of 14 native species, mainly distributed in cerrado. These Hibiscus are hairy shrubs, with showy flowers of pink corolla, dark base, 5-toothed staminal tube apex, loculicidal capsule of 5 cells. The species inhabit wet ecosystems of the atlantic rainforest and cerrado. After the last study of Hibiscus taxonomy evidencing four endemic species from Minas Gerais state, showed to have the largest endemism center of Hibiscus in Brazil, therefore, using IUCN classification methodology, we indicated H. hilarianus and H. multiformis as vulnerable, H. itirapinensis as endangered and H. mariae as critically endangered. The species are represented by small isolated populations distributed at the mountains and plateaus between Espinhaço mountain range and Planalto Paulista, considered a region with great endemic biodiversity. According to the previously analysis, it is recommended specific studies with techniques and appropriate methodology to research the development and evolutionary characteristics of hibiscus species in Minas Gerais state.

ABSTRACT The objective was to present the floristic survey of the bryophytes of the Parque Estadual da Serra do Brigadeiro. It included an evaluation of the species richness, as well as information about the substrate preference of each species and its geographic distributions in Brazil. We found 208 taxa of bryophytes: one hornwort, 88 liverworts and 119 mosses. This richness represents ca. 26% of the bryoflora of Minas Gerais State and ca. 13% of that known for Brazil. Eighteen of the bryophytes species are endemic to Brazil, whereas 19 species are recorded for the first time in Minas Gerais. The bryoflora showed preference for tree bark (30%) and rock (23%) as substrates. Our data show that the Parque Estadual da Serra do Brigadeiro is an important area for the diversity conservation of Brazilian bryophytes and maintenance of endemic species of the country.

We report here the rediscovery of Phyllanthus itatiaiensis Brade (Phyllanthaceae) after 50 years, as well as its occurrence in Minas Gerais State in southeastern Brazil. We provide a taxonomic diagnosis, in situ photographs, a distribution map, and a reassessment of its conservation status, which will contribute to our knowledge of this rare and endemic species as well as our ability to protect it.

Abstract—Three new species of Eriocaulaceae, endemic to the Serra da Canastra in Minas Gerais state, are described. Paepalanthus petraeus is assigned to P. ser. Paepalanthus, differing within the series by its thickened stem accumulating leaf sheaths, linear leaves, and numerous scapes shorter or equaling the leaf height and bearing capitula with brown involucral bracts. Paepalanthus sinuosus belongs to P. subsect. Polyactis and is distinguished by few scapes in lax fascicles, more than twice as long as the leaves, which are patent to slightly recurved, and light brown involucral bracts with acute apex. Syngonanthus culcitosus, within S. sect. Syngonanthus, is unique due to its elongate and branched stem forming dense mats, simple inflorescences, cream-colored involucral bracts equaling the length of the floral disc, and gynoecium with nectariferous appendages. Comparisons with the most similar species are provided for each new taxon. Maps, photographs, and illustrations are presented, together with comments on phenology, distribution, habitat, and morphology. Paepalanthus petraeus and P. sinuosus are likely to be assessed as Critically Endangered, and S. culcitosus as Vulnerable, according to IUCN criteria.

A new species of Inga (Leguminosae, Caesalpinioideae, Mimosoid clade), restricted to the Atlantic Forest of Minas Gerais State, Brazil, is described, illustrated, and compared in an inedited identification key to the species with stipitate extrafloral nectaries in the biome, Inga ciatiformis is similar to Inga cabelo and Inga platyptera. It differs from I. cabelo by having appressed-sericeous young branches, leaves with 1–3 pairs of leaflets, a terminal appendix 7–12 mm long, cyathiform extrafloral nectaries, bracts 9–13 mm long, linear, persistent, and a sparsely sericeous calyx (vs. hirsute-hispid young branches, leaves with 2–5 leaflets pairs, terminal appendix 2.5 mm long, capitate extrafloral nectaries, bracts 2 mm long, triangular, caducous, and a hirsute calyx). It differs from I. platyptera by having appressed-sericeous young branches, a cylindrical petiole and rachis, rachis rarely winged in the superior portion of the apical pair of leaflets, extrafloral nectaries always cyathiform, and linear bracts (vs. hispid young branches, winged petioles and rachises, extrafloral nectaries generally cupuliform, and lanceolate to ovate bracts).

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.

Hyptidendron albidum a new and endemic species from Northern Minas Gerais state, Brazil, is here described. This new species is unique due to the morphological combination of its dense indumentum of white dendroid trichomes, covering much of the plant and the inflorescence composed of a unilateral cymose structure. The new species is morphologically similar to H. unilaterale which displays a similar unilateral cymose structure but differs in its indumentum, inflorescence length and leaf morphology. We provide a description, an illustration, a conservation status assessment, a distribution map, and comments on the recognition of this new species.

Since it was trapped in the XIX th century, Rhagomys rufescens has been considered a rare endangered sigmodontine rodent and an endemic species of the Atlantic forest. Only a handful of vouchers of this taxon were known by Thomas, 1886. Recently, eight new individuals were collected, providing new geographical, morphological and phylogenetic (based on molecular evidence) information on this species. In the present work we report the southernmost occurrence record for R. rufescens at Indaial, Santa Catarina State, with the largest collected series of this species, the northernmost occurrence record at Santa Teresa, Espírito Santo State, and new records from Poços de Caldas, Minas Gerais State, from Ibiúna and Ribeirão Grande, São Paulo State.
