Une espèce nouvelle de Pleurothallidinae est décrite dans le genre Pabstiella et illustrée.

La position systématique de ce groupe est discutée, essentiellement sur la base des résultats de phylogénie moléculaire déjà publiés. Dans l'état actuel des connaissances, c'est le genre Pabstiella Brieger & Senghas qui convient le mieux pour traiter ces plantes. Chacune des espèces concernées est décrite et illustrée. Finalement, une clé d'identification des espèces est proposée.

Such a form is presently described and illustrated for Pteroglossa glazioviana.

Notylia angustifolia Cogniaux is reported for the first time for the Brazilian State of Amazonas.

Its presence in Brazil is thus confirmed ans extended. A morphological description and some pictures are provided in order to ease its field identification.

Such a form, from Minas Gerais (Brazil), is presently described and illustrated for Pabstiella pellifeloides (Barbosa Rodrigues) Luer

The species was found in Burarama, district of Cachoeiro de Itapemirim, in the southern part of the Serra do Castelo in semideciduous forest. Hitherto the species have been known from the North (PA), Shoutheast (MG, RJ) and South (PR, SC, RS). A description ans illustration are provided for a better identification.

The species was found in Burarama, district of Cachoeiro de Itapemirim, south of Serra do Castelo in semideciduous forest. A description ans an illustration are provided for a better identification.

The main differences with the former, as well as its affinities with other Brazillian Anathallis, are discussed.

This species, from the Serra do Castelo, in Espirito Santo, is a member of the "Acianthera saundersiana" alliance, a group belonging to section Sicariae, sub-section Auritae. It is compared to the two species wich are, in our opinion, most closely relative to it, Acianthera bidentula (according to the vegetative characters) and Acianthera saundersiana (according to the floral features).

They are compared to their close relatives, respectively Pabstiella cordilabia, P. hians and Anathallis kautskyi.

Dichaea fusca Valsko, Holland & Krahl is similar to Dichaea rendlei Gleason, but differs in its vegetative and floral morphology, particularly in the lip.

Inside the country, the Atlantic Rain Forest, very devastated over the years, it's probably one of the richest biomes. The “Serra do Castelo”, in the state of Espirito Santo, is one of the greatest diversity of this biome sites and therefore one of the areas where there is the largest number of orchid species: about 700. To display all of them, four volumes were required .
In the first part, the study area is presented in its various aspects: geography, geology, climate, endemism, natural history of orchids and history of its discoverers. The second part is dedicated to the presentation of 700 species, divided into 145 genera, belonging to three subfamilies: taxonomy, geographical distribution, material studied, complete morphological description, accompanied whenever possible with a photograph of colored flower and a botanical board.
