The genus Palmorchis (Orchidaceae: Neottiae) in Peru: A taxonomic synopsis including four new species and a new record

Abstract

A taxonomic synopsis of Peruvian Palmorchis with six accepted species is provided including four new species (P. blancae, P. liberolabellata, P. loretana and P. yavarensis) and a new record previously reported only for Ecuador (P. imuyaensis). This overview is the result of a review of local herbaria, taxonomic literature, and a field study of the genus. An artificial key for all Peruvian Palmorchis species is presented, as well as photographs and a map of known localities in Peru. Resumen. Se presenta una sinopsis taxonómica de Palmorchis peruanas con seis especies aceptadas, incluyendo cuatro nuevas especies (P. yavarensis, P. blancae, P. liberolabellata y P. loretana) y un nuevo registro (P. imuyaensis) previamente reportado sólo para Ecuador. Este resumen es el resultado de la revisión de herbarios locales, literatura y el estudio de campo del género. Se presenta una clave artificial para todas las especies de Palmorchis peruanas, así como fotografías y un mapa de todas las localidades conocidas en Perú.

Synopsis of EcuadorianPterichis(Orchidaceae)

“…Recognizing species composition is essential to preserve wildlife by identifying areas important for biodiversity and ecosystem services (Sofo, 2011;Casetta, Marques da Silva & Vecchi, 2019). For that reason, taxonomists are continuously publishing articles not only introducing the novelties in local biota, but also more comprehensive articles presenting concepts of particular plant or animal group (Ormerod, 2018;Damián Parizaca & Torres Montenegro, 2018). Orchidaceae and Asteraceae, with a rate of 500 new species being described each year (Chase et al, 2015), are among the most problematic groups to work with.…”

Palmorchis triquilhada sp. nov. (Orchidaceae; Neottieae) from the Brazilian Amazon

“…Szlachetko et al () recently established a preliminary infrageneric classification system based mainly on morphological characteristics of the lip and divided the genus into six informal groups: the Palmorchis carlos‐parrae group, Palmorchis powellii group, Palmorchis nitida group Palmorchis pubescente group, Palmorchis trilobulata group and Palmorchis sobralioides group. In addition, recent efforts to systematize taxonomic knowledge about the genus have resulted in the recognition of nine new species for Colombia, Ecuador and Peru, indicating that the diversity of Palmorchis may be underestimated (Parizaca and Torres Montenegro , Szlachetko et al ).…”
