We describe and illustrate Aristolochia assisii, a new species assigned to subseries Anthocaulicae. This subseries is characterized by the presence of extremely short and ramiflorous racemes in which each flower is subtended by a small bract. The inflorescences and the flowers of the new species are morphologically similar to those found in three woody climbers of this subseries (A. bahiensis, A. disticha and A. subglobosa); however, it clearly differs by the herbaceous condition, a trait extremely rare in cauliflorous species that suggests neoteny, and the possession of a long, cylindrical rhizome and a tapered rostrum to 1.2 cm long in the capsule. So far, A. assisii is the third species of the subseries Anthocaulicae known to occur in the Atlantic Forest of Brazil.

We describe a new species of dull-colored flea-toad, genus Brachycephalus, from the Atlantic Forest of Caparaó mountains in southeastern Brazil. The new species is characterized by its diminutive size, “leptodactyliform” body, brownish color with an inverted V-shaped dark mark on dorsum, skin smooth, hyperossification and dorsal shield absent, linea masculinea absent, Fingers I and IV vestigial, Toe I externally absent, Toe II reduced but functional, Toes III and IV with pointed tips, Toe V vestigial, and ventral color uniformly brown. It is a leaf litter dweller, known only from type locality in the humid forests on the eastern slopes of Parque Nacional do Caparaó mountains, a protected area in the states of Espírito Santo and Minas Gerais, southeastern Brazil. It is the third flea-toad occurring in the state of Espírito Santo recovered as sister to all other Brachycephalus distributed from the state of São Paulo northward in the Atlantic Forest.

The Atlantic Forest is one of two biodiversity hotspots in Brazil (Mittermeier et al. 1997, Myers et al. 2000). It is the second most diverse (Forzza et al. 2010) and threatened biome because only ca. 11.7% of the Atlantic Forest remains (Ribeiro et al. 2009). Annonaceae are well represented in the Atlantic forest with 92 species, of which 71 are endemic (Maas et al. 2015). In the State of Espírito Santo, there are 12 genera and 44 species (Maas et al. 2015). The majority of genera in Annonaceae that occur in Brazil are represented in Espírito Santo, but previously there were no records of Trigynaea Schlechtendal (1834: 328) for the State.

Tocoyena atlantica, a new species endemic to southern Bahia and northern Espírito Santo states, Brazil, is here described and illustrated. The species consists of trees 5−8 m tall; with petioles 2−5 cm long, and leaf blades 7.4−24.5 × 2.5−9.1 cm, elliptic, adaxially glabrous; calyces cup-shaped with triangular lobes; corolla yellow during anthesis, with tube gradually wider towards the mouth; and laterally compressed hypanthia. Based on IUCN criteria, we consider T. atlantica endangered, with three collection localities within the Atlantic Forest domain. An identification key for species of Tocoyena occurring in the Brazilian Atlantic Forest is also provided.

This paper reports a new species of Psidium found only in the Atlantic Forest of Espírito Santo and Rio de Janeiro, Brazil. Psidium grazielae is related to P. cauliflorum, differing mainly by membranaceous to chartaceous leaves with glandular dots visible on both faces, inconspicuous secondary veins, as well as the absence of trichromes on branches, inflorescences and fruits. We provide the description and illustrations for this new species. The relationship of P. grazielae and P. cauliflorum is discussed, and comments concerning the taxonomy and ecology of the new species are provided.

Abstract A new species of Trichilia (Meliaceae) from Southeastern Brazil is here described, illustrated and compared to its closest related species. Trichilia arenaria sp. nov. is morphologically similar to T. casaretti, T. elegans and T. pallens. An identification key and comparison table for T. arenaria and those three species from Atlantic Forest of Espírito Santo are also presented.

We describe and illustrate Aristolochia subglobosa, a new species assigned to subseries Anthocaulicae. The subseries is characterized by the presence of extremely short and cauliflorous racemes in which each flower is subtended by a small bract. The new species is related to A. bahiensis, A. daemoninoxia and A. guentheri. So far, A. subglobosa is the second species of this subseries known to occur in the Atlantic Forest of Brazil.
