During field works in Espírito Santo, Minas Gerais and Bahia states, it was notified four news registers of Begonia species. Begonia dietrichiana, B. glabra and B. platanifolia to Espírito Santo state and Begonia admirabilis to Bahia and Minas Gerais states. Descriptions, illustrations, geographic distribution data, maps, information on the habit, phenology, sections and vegetative differences are provided.

The genus Euparkerella is composed of four species endemic to the Atlantic Rainforest biome, ranging from Espírito Santo to Rio de Janeiro, Brazil. Three of them are known only to their type locality. According to the IUCN, the species Euparkerella tridactyla is currently classified as Vulnerable to Extinction due to its apparently low population density and restrict geographic distribution. Previously, E. tridactyla was known only from the type locality (650 m.a.s.l.), municipality of Santa Teresa, state of Espírito Santo. Herein, we provide new distribution records for E. tridactyla that extend its range by 70 kilometers to the south, encompassing four different municipalities, and increase the altitudinal distribution to a range between 550- 700 m.a.s.l.

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. © 2014 Magnolia Press.

The objective of this study was to evaluate the epiphytic community from a fragment of the Atlantic Forest in the montainous region of Espirito Santo state, aiming at observing the distribution of this form of life on phorophytes. The study site is made up by a preserved forest hillside which was analyzed at the top of the hill (Area 1 - altitude of 890 m) and on a slope (Area 2 - 720 m altitude). The method used in the experiment was the centered quarter, selecting 15 points for each area, totaling 120 phorophytes with DBH ≥ 10 cm. For the analysis of epiphytes distribution, the phorophytes were divided into the following strata: low, medium and high shaft, internal and external canopy. Each epiphyte received a frequency grade, resulting in the phytosociological parameters: epiphytic importance (VIe), dominance and frequency (absolute and relative). Twenty-nine species of epiphytes and hemiepiphytes were recorded, and the most representative families were Bromeliaceae (7 species) and Orchidaceae (6 species). There was a low similarity between the two areas (IS = 0.3) with only five species in common. The species with the highest epiphytic importance were two hemiepiphytes: Heteropsis rigidifolia in Area 1 (VIe = 29.1) and Polybotrya espiritosantensis in Area 2 (Vie = 15.3), the first record of the genus Polybotrya as important taxon in epiphytic structure. The richness was low compared to other studies with epiphytes, however, the presence of rare and endangered species demonstrates the importance of the studied forest for the conservation of taxons in the Atlantic Forest.

Five species of Pleurothallis R. Br. s.l. are transferred to Pabstiella Brieger & Senghas (Orchidaceae): Pabstiella armeniaca (Barb. Rodr.) L. Kollmann, Pabstiella fragae (L. Kollmann & A. P. Fontana) L. Kollmann, Pabstiella henrique-aragonii (Pabst) L. Kollmann, Pabstiella mentigera (Kraenzl.) L. Kollmann, Pabstiella ramphastorhyncha (Barb. Rodr.) L. Kollmann. Lepanthes armeniaca Barb. Rodr. is lectotypified. Two new species of Pabstiella, Pabstiella cipoensis L. Kollmann and Pabstiella rupicola L. Kollmann, are described and illustrated from Brazil. Information on the ecology and geographic distribution of the new taxa is also provided. © CONSERVATOIRE ET JARDIN BOTANIQUES DE GENÈVE 2010.
