To understand such transitions, the availability of detailed anatomical data and species-level phylogenies are crucial. We investigated the evolution of food deception in Epidendrum, one of the largest orchid genera, using genus phylogeny to map transitions between nectar gain and loss among different clades. Associations between anatomical and histochemical changes and nectar gain and loss were examined using fresh material available from 27 species. The evolution of nectar presence/absence in Epidendrum species was investigated in a phylogenetic framework of 47 species, using one nuclear and five plastid DNA regions available from GenBank and sequenced in this study. Results: The presence or absence of nectar was strongly associated with changes in the inner epidermal tissues of nectaries. Nectar-secreting species have unornamented epidermal tissue, in contrast to the unicellular trichomes found on the epidermis of food deceptive species. Bayesian tests confirmed that transitions occurred preferentially from nectar presence to nectar absence across the Epidendrum phylogeny. In addition, independent nectar loss events were found across the phylogeny, suggesting a lack of constraint for these transitions. Conclusions: Ornamented nectaries may play an important role in the deceptive pollination strategy by secreting volatile organic compounds and providing tactile stimuli to pollinators. The recurrent and apparently irreversible pattern of nectar loss in Epidendrum suggests that food deception may constitute an alternative evolutionarily stable strategy, as observed in other orchid groups.

Marantaceae is a family with approximately 550 species distributed throughout the tropics, with the exception of Australia (Andersson 2003). Calathea Meyer (1818: 6) used to be the largest genus in the family, previously including ca. 300 species. After the molecular study on the genus by Borchsenius et al . (2012), which confirmed the genus as polyphyletic, Goeppertia Nees (1831: 337) was resurrected to include all the species (approximately 245) that were not in the former subgenus Calathea Kornicke (1862: 112), the Calathea lanicaulis group (Kennedy et al. 1988) and the synonymized genus Sanblasia Andersson (1984: 21). Goeppertia thus became the most representative genus of Marantaceae, in Brazil represented by ca. 100 species (Braga 2013). It is found chiefly in rainforest habitats at elevations, below 1500m (Kennedy et al. 1988). However, the number of species may yet be underestimated due to unknown diversity of Brazilian species occurring in drier areas.

A new species from the Atlantic forest of northeastern Brazil, Goeppertia yoshida-arnsiae, is described and illustrated. It is morphologically similar to G. umbrosa (Körnicke 1862: 137) Borchsenius & Suárez (2012: 635), but differs mainly by the indumentum of the leaf blades and petioles, length of the peduncles, number of bracteoles per pair of flower, and indumentum of the sepals.

Foram encontradas 661 espécies em 129 famílias, as dez fanerogâmicas mais diversas foram: Asteraceae (56 espécies), Fabaceae (37), Rubiaceae (29), Poaceae (25), Solanaceae (24), Cyperaceae (19), Euphorbiaceae (19), Orchidaceae (19), Melastomataceae (17), e Piperaceae (17). O acréscimo de 322 espécies adicionais compiladas de listagens florísticas suplementares eleva, para a Serra do Japi em geral, o número registrado a 976 espécies em 141 famílias. Comparada a outros levantamentos florísticos na Mata Atlântica, esses resultados demonstram a diversidade florística da área estudada e ressaltam o valor da preservação da vegetação nessa região altamente urbanizada. Floristic sampling was carried out in Serra do Japi Biological Reserve, Jundiaí, state of São Paulo, Brazil, including physiognomies of semideciduous montane forest, a type of forest formation within the Atlantic Forest domain. Six hundred and sixty one species distributed in 129 families were recorded; the ten most diverse phanerogam families were: Asteraceae (56 species), Fabaceae (37), Rubiaceae (29), Poaceae (25), Solanaceae (24), Cyperaceae (19), Euphorbiaceae (19), Orchidaceae (19), Melastomataceae (17), and Piperaceae (17). The addition of 322 species from other floristic surveys increased the number of species of Serra do Japi to 976, distributed in 141 families. Compared to other floristic surveys carried out in the Atlantic Forest, our results highlight the floristic diversity of the study area and the importance of preserving the vegetation of this highly urbanized region.

A recent molecular based phylogeny (Borchsenius et al. 2012) redefined the genus Goeppertia Nees (1831: 337) to include all the subgenera of Calathea Meyer (1818: 6) proposed by Schumann (1902) with the exception of C . subgenus Calathea Kornicke (1862: 112). As a result, several species of Calathea recently described were transferred to Goeppertia (Braga 2014). Similarly, a taxonomic revision of the Brazilian species, currently carried out by the first author, led to the conclusion that Calathea polytricha Baker (1894: 497) should be combined in Goeppertia . This species features the synapomorphies of Goeppertia , such as simple inflorescences and corolla lobes straight to spreading, and belongs to Schumann’s subgenus Pseudophrynium Kornicke (1862: 113). During the taxonomic revision, other names have been considered synonyms and are typified here.

Resumo A Reserva Particular do Patrimonio Natural (RPPN) Paiol Maria possui 76 ha de Floresta Ombrofila Densa Montana e esta localizada no municipio de Sao Lourenco da Serra, Sao Paulo, Brasil, pertencente ao Corredor de Biodiversidade da Serra do Mar. Objetivando elaborar uma listagem floristica das especies vasculares nao arboreas ocorrentes na RPPN, foram realizadas coletas durante o periodo de junho de 2010 a setembro de 2011. Foram inventariadas 330 especies, distribuidas em 84 familias e 223 generos. Das especies amostradas, quatro sao consideradas ameacadas no Estado de Sao Paulo. A analise de similaridade entre as especies epifitas ocorrentes na RPPN e outras quatro areas de Floresta Ombrofila Densa Montana localizadas na Serra do Mar reafirma a importância de fragmentos em regeneracao secundaria para o conhecimento e conservacao da biodiversidade da Floresta Atlântica. Palavras-chave: floresta montana, floresta secundaria, Floresta Atlântica, epifitas. Abstract The private owned conservation area of RPPN Paiol Maria includes 76 ha of montane forest located at the municipality of Sao Lourenco da Serra, Sao Paulo State, belongs to the biodiversity corridor of the Serra do Mar, and is located at the northern part of Ribeira valley. This study was carried out during the period of June 2010 to September 2011 and our aim was to elaborate a checklist of the non-arboreal species occurring in the RPPN. A total of 330 species, distributed in 84 families and 223 genera were collected. Four species recorded for this work appears in the red list for the state of Sao Paulo. A similarity analysis between the epiphytes found in the RPPN and other four areas of montane forest reassert the important role of secondary forest fragments to the knowledge and conservation of the Atlantic Forest biodiversity. Key words: montane forest, secondary forest, Atlantic Forest, epiphytes.
