Abstract—Solanum adamantium is described from Serra de Grão Mogol, located in the Espinhaço range, in northern Minas Gerais State, Brazil. The new species is ecologically and morphologically similar to the prickly species S. buddleiifolium and S. thomasiifolium, from which it differs in a series of vegetative and reproductive characters. We discuss the morphological similarities and differences among these species, as well as certain aspects of the new taxon’s ecology and geographic distribution. Images of diagnostic characters, a map of geographical distribution, a preliminary conservation assessment, and full specimen citations are provided.

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

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.

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.

We describe and illustrate three new species of Paepalanthus (Eriocaulaceae: Paepalanthoideae) from the Espinhaço Range: P. argyrotrychus, P. farinaceus and P. velutiphyllus, all endemic to Serra do Ambrósio, a mountain disjunct from the Espinhaço Range in the municipality of Rio Vermelho, Minas Gerais, Brazil. These species belong to Paepalanthus ser. Paepalanthus (=Paepalanthus [unranked] Variabiles). We provide detailed descriptions and illustrations for each taxon, as well as comments on habitat, distribution, morphology, conservation and their affinities to the most morphologically similar species.

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.

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.

Species Descriptions

Pombalia Vand. (Violaceae) is represented in the Cerrado by a well-supported monophyletic group of species known as the Pombalia lanata complex, characterised by some unique vegetative and reproductive features within the genus. This group includes six species – Pombalia cristalina, P. insignis, P. lanata, P. poaya, P. strigoides and P. velutina – the first two of which are new to science. Pombalia lanata shows the widest geographical distribution throughout the Central Brazilian Plateau and the Espinhaço Range in Minas Gerais state, with a disjunction in Misiones Province, Argentina. Because most species in this group are narrow endemics, we evaluated the conservation status of all taxa. An identification key for the species, descriptions, illustrations, maps of geographical distribution and nomenclatural notes are also provided.
