“…2) Eriopsidinae (Fig. 2) but the two data sets recovered the same major clades, supporting the generic concepts presented by Blanco et al (2007). Our sampling included two individuals of several species; in each pair, there are nucleotide differences separating the two, indicating that ycf1/ matK is often capable of resolving not only closely related species but also intraspecific variation.…”

Relationships among all subtribes of Neotropical Cymbidieae (Orchidaceae) were estimated using combined matK/ycf1 plastid sequence data for 289 taxa. The matrix was analyzed using RAxML. Bootstrap (BS) analyses yield 100% BS support for all subtribes except Stanhopeinae (87%). Generic relationships within subtribes are highly resolved and are generally congruent with those presented in previous studies and as summarized in Genera Orchidacearum. Relationships among subtribes are largely unresolved. The Szlachetko generic classification of Maxillariinae is not supported. A new combination is made for Maxillaria cacaoensis J.T.Atwood in Camaridium.

-(Orchidaceae in a fragment of semideciduous slope forest in the southern Espírito Santo State, Southeastern Brazil). The present study aimed to inventory and elaborate descriptions and illustrations for the species of Orchidaceae found in a forest located in the southern Espírito Santo State, a region of few botanical studies, featuring a poorly known flora. During the study, 25 species were found and distributed into 21 genera. The majority of the species were epiphytic, represented by 16 species, followed by rupiculous, terrestrial, and mycoheterotrofic species. Most species flourished during the hot and humid period. Furthermore, the study revealed the presence of an endemic species and three new records for the State.

O presente trabalho teve como objetivo inventariar e elaborar descrições e ilustrações para as espécies de Orchidaceae encontradas em um fragmento de Floresta Semidecídua localizado no sul do Estado do Espírito Santo, região de poucos estudos, caracterizando uma flora ainda pouco conhecida. Durante o estudo, 25 espécies distribuídas em 21 gêneros, foram registradas. A forma de vida predominante foi a epifítica, caracterizada por 16 espécies, seguida pela rupícola, terrícola e micoheterotrófica. A maior parte das espécies floresceu no período quente e úmido. Além disso, o estudo revelou a presença de uma espécie endêmica e três novas ocorrências para o Estado.

“…However, molecular phylogenetic analyses published by Whitten et al (2007) using DNA sequences from more than 600 specimens allowed for a new interpretation of the subtribe that has been useful for redefining particular genera (Whitten & Blanco 2011). Based on wellsupported clades in the gene trees and defined by morphological synapomorphies, several genera of Maxillariinae were recircumscribed by Blanco et al (2007). One genus in particular, Mormolyca Fenzl, changed significantly.…”

ABstrAct. The Neotropical orchid genus Mormolyca Fenzl, as currently circumscribed, encompasses a diverse group of ca. 27species. Many of these were included traditionally in Maxillaria sect. Rufescens, when similarity of floral morphology was considered foremost in their classification rather than the evolutionary history of the taxa. In order to begin revising species delimitation and clarifying the evolution and biology of the genus, we present a phylogenetic hypothesis using sequence data from five plastid loci (rpoC1, matK gene and flanking trnK intron, atpB-rbcL intergenic spacer, and the 3' portion of ycf1) and the nuclear ribosomal internal and external transcribed spacers (ITS, ETS). Resulting trees using both Bayesian and parsimony inference are congruent with each other, and generally well resolved. Based on current level of sampling across Maxillariinae, these molecular data support the monophyly of Mormolyca and shed light on the interspecific phylogenetic patterns within the genus. These include an early divergent paraphyletic grade of Mormolyca species successively sister to a clade with at least two definable subclades within. The latter are characterized by two different flower morphologies that are likely related to their pollination systems. Although not all relationships within the genus are fully resolved or supported, these results offer a first glimpse into the phylogeny of a small group of epiphytic orchids characterized by an unusually high level of variable vegetative characters, floral fragrance profiles, and pollination systems.
