Paepalanthus mellosilvae is here described and illustrated as a new species of Eriocaulaceae from the Atlantic Forest domain in Minas Gerais state, Brazil. The new species is known from a single locality in the Mantiqueira Range, growing along trails through cloud forests. According to the IUCN criteria, it is suggested here as critically endangered. Paepalanthus mellosilvae is compared to P. harmsii, a morphologically similar species also growing in the Mantiqueira Range, being mainly distinguished by the presence of a rhizome, narrower leaves, more numerous scapes, narrower capitula, sparsely pilose involucral bracts, and obdeltate floral bracts. Additional comments on the taxonomy, morphology, and distribution of the species, along with illustrations are provided. The specific epithet is a tribute to Prof. Dr. Renato de Mello-Silva.

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.

The new species Chrysophyllum pubipetalum from the Brazilian Atlantic forest of Espírito Santo state is described and illustrated. This new species is characterized by the presence of trichomes on both surfaces of the corolla (a character unique in the genus), channeled petioles, a relatively short pedicel length, and various characters of the fruits and seeds. A distribution map and a table distinguishing the new species from morphologically similar species are also included. As based on IUCN criteria, the species is considered critically endangered.

Behuria mestrealvarensis (Melastomataceae) from the state of Espírito Santo, Brazil, is described, illustrated and compared with B. capixaba, the species most similar to it. Behuria mestrealvarensis differs from B. capixaba by the glabrous petioles and hypanthia, by the solitary flowers or these in simple or compound triads up to 7 flowers, elliptic bracteoles almost the same size of the pedicel and hypanthium, sepals with eciliate margins and ovary apex with trichomes up to 0.5 mm. It occurs in a single locality, on an isolated, ca. 800m elev. inselberg. Due to its restricted occupancy area, fragmented landscape and poor habitat quality, this species must be considered as Critically Endangered according to IUCN criteria.

A New Species

We describe Waltillia itambana, a new species placed in the previously monotypic genus Waltillia, presenting as main differences from Waltillia hatschbachii features such as a water-impounding rosette, shorter and broader leaves, divergent non-secund flowers and the light-green petals. The species is, as far as known, restricted to Pico do Itambé State Park, in Minas Gerais, growing above 1500 m of elevation in the rupestrian grasslands, of the Diamantina Plateau, Espinhaço Range, Minas Gerais State. We compare W. itambana with other similar species that occur in the rupestrian grasslands and provide illustrations, information on geographic distribution, a map, and ecological and conservation observations on the new species.

A New Species

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.

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).

We describe Miconia lucenae R.Goldenb. & Michelang., a new species from the montane Atlantic Forest in Santa Teresa in the state of Espírito Santo. Our analysis, based on three plastid spacers (atpF-atpH, psbK-psbl and trnS-trnG), one plastid gene (ndhF, not available for M. lucenae), and two nuclear ribosomal loci (nrITS and nrETS), showed that it belongs to a small clade with Miconia paradoxa (Mart. ex DC.) Triana (Minas Gerais) and M. michelangeliana R.Goldenb. & L.Kollmann (Espírito Santo). The three species in the “Paradoxa clade” can be recognized by the plants with glabrous or glabrescent branches and leaves, white petals and yellow stamens, these with the connectives not prolonged below the thecae, ventrally unappendaged, dorsally unappendaged or with a minute tooth, the latter bilobed or not, glabrous ovary, and the fruits with a persistent calyx. Miconia lucenae can be recognized, among the species in this clade, by the shrubby plants with terete young branches, short inflorescences, usually with red axes, and the 2-bracteolate, sessile, 4-merous flowers, with a ciliolate inner portion of the sepals, lanceolate petals, and 4-celled ovaries. This species can be considered as endangered according to IUCN criteria.

A New Species

Colanthelia is a woody bamboo genus belonging to the Arthrostylidiinae and currently includes nine species. It can be recognized by a suite of morphological characters including hollow and thick-walled culms, branch complement with a promontory in the base and a dominant divergent branch bearing few to many secondary small branchlets from its base, culm leaves with a relatively well developed girdle and a crest or skirt at the juncture of the sheath and girdle, racemose or weakly paniculate synflorescences, and relatively long and narrow spikelets with visible rachilla internodes. During recent fieldwork in Minas Gerais state, a new species, Colanthelia longipetiolata, from the Brazilian Atlantic forest was collected, which is here described and illustrated. So far as we know, the species is endemic to the Caparaó National Park, in Minas Gerais state. Comments on its habitat, distribution and conservation status, a morphological comparison between C. longipetiolata and C. sparsiflora, and a revised identification key to all species of the genus are provided.

Microvelia joceliae Magalhães & Moreira, sp. nov. is described and illustrated based on material from Parque Natural Municipal das Andorinhas, Minas Gerais State, in southeastern Brazil. The new species can be distinguished from congeners occurring in the region by the pronotum of the apterous form covering almost the entire thorax dorsally, proepisternum with black denticles, male abdominal segments V–VII ventrally depressed, shape of the asymmetrical parameres, and female abdominal laterotergites reflected over the mediotergites and almost touching over segments V–VII.
