“…Os exemplares foram identificados ao nível específico através de consulta aos protólogos e tipos nomenclaturais, e comparações com descrições em obras especializadas que contemplam de maneira abrangente o gênero (Cogniaux 1896;Pabst & Dungs 1978;Foster 2007), além de análises comparativas do material depositado nos diversos herbários acima citados. A terminologia morfológica adotada foi baseada em Rizzini (1977), Stearn (1983) e Luer (2002). Com exceção dos novos sinônimos aqui propostos, todos os outros seguem a base de dados The Plant List (2018).…”

Resumo Octomeria (Orchidaceae: Pleurothallidinae) consiste de cerca de 150 espécies neotropicais, das quais aproximadamente 95 ocorrem no Brasil. Através de consultas a herbários nacionais e estrangeiros, além da realização de trabalho de campo, 21 táxons foram encontrados no Paraná. Octomeria lilliputana revelou-se endêmica para o estado e Octomeria leptophylla uma nova ocorrência. O gênero ocorre em todas as fisionomias vegetais do Paraná, principalmente na Planície Litorânea e Primeiro Planalto. Segundo os critérios da IUCN, cinco espécies se enquadram na categoria “CR”, nove na categoria “EN”, duas nas categorias “NT”, “LC” e “DD”, e uma delas, Octomeria concolor, presumidamente extinta (“EW”) no Paraná. Dois novos sinônimos são propostos: Octomeria hatschbachii, sinônimo de Octomeria chamaeleptotes, e Octomeria caetensis, sinônimo de Octomeria palmyrabellae. Lectótipos são selecionados para Octomeria chamaeleptotes e Octomeria hatschbachii. São apresentados uma chave de identificação das espécies, descrições, ilustrações, discussões taxonômicas, lista de material examinado, dados sobre distribuição geográfica e estado de conservação dos táxons.

“…Pleurothallis minutilabia is placed in the group Macrophyllae-Fasciculatae (Luer 1986(Luer , 1988(Luer , 2005 based on morphological attributes: spreading-to-erect, well-developed ramicauls; sessile, cordate leaves, not in same plane as ramicaul; single-flowered inflorescence emerging from the apex of the ramicaul at the base of the leaf; short peduncle and pedicel mostly hidden within the reclining spathaceous bract; apical anther; and transversely bilobed stigma. Morphologically P. minutilabia does not fit within section Abortivae (Luer 1980(Luer , 1998 or within the single-flowered subsection Acroniae series Amphigyae Luer (Luer 1998), because these species typically have less well developed ramicauls; sessile, but rarely cordate leaves, usually in the sample plane as the ramicaul; a longer, terete column; longer peduncles and pedicels emerging some distance from the spathaceous bract; and an oval, rather than bilobed, stigmatic surface. While not closely related, the flowers of Pleurothallis minutilabia (Macrophyllae-Fasciculatae) and Pleurothallis kaynagata (Abortivae) are superficially similar and could be confused.…”

A new species of Pleurothallis (Orchidaceae: Pleurothallidinae) in subsection Macrophyllae-Fasciculatae with a unique, highly reduced, morphologically distinct labellum

et al. 2018

Pleurothallis minutilabia, a species unique in subsection Macrophyllae-Fasciculatae because of the minute, highly reduced lip, is described and compared to the most similar species in the subsection. It is also compared morphologically to Pleurothallis kaynagata from section Abortivae, to which P. minutilabia is not related, but which also possesses a highly reduced lip. The morphology of the flower of P. minutilabia is discussed briefly in relation to possible pollination mechanisms. The distribution, restricted to Zamora Chinchipe, southern Ecuador, and the conservation status are addressed. Key words / Palabras clave: cloud forest, Ecuador, labellar morphology, Pleurothallis, pollination

A new species of Andinia (Orchidaceae, Pleurothallidinae) from Huánuco, Peru, and the first Peruvian locality for Andinia schizopogon

A new species of Andinia in subgenus Andinia from Tingo María National Park is described, illustrated and compared to the most similar species pair. Andinia tingomariana is distinguished by unguiculate, reniform, ciliate petals, a longer column without the terminal dilation and a trilobed, ciliate lip in which the narrow, semi-auriculate lateral lobes project upward around the column, adnate in the middle, creating a furrowed surface. The floral morphology of the new species is compared to that of the phylogenetically unrelated Salpistele group of Stelis and possible convergent evolution of pollination syndromes is discussed. Finally, the first confirmed locality of A. schizopogon is reported and a preliminary list of Andinia species in Peru is provided.
