Phylogenetics and taxonomy of Habenaria sect. Micranthae (Orchidaceae), with the description of an overlooked new species from the Espinhaço mountain range, Eastern Brazil

Checklist and molecular phylogenetics reveal three taxonomic novelties in Habenaria (Orchidaceae, Orchidoideae) from Chapada dos Veadeiros, Goiás, Brazil

“…In terms of overall results of the phylogenetic analyses, the main differences between our results and some of the earlier molecular phylogenetic studies (Batista et al 2013(Batista et al , 2014(Batista et al , 2016(Batista et al , 2018Cruz-Lustre et al 2022;Lau et al 2021) were the position of H. monorrhiza (Sw.) Rchb.f. and subclade 1 (H. sect.…”

“…To investigate the phylogenetic relationships of the putative new taxa we performed an initial analysis using the same dataset as Batista et al (2013), which comprises ca 51% of the Neotropical species of Habenaria and 1,389 bp of the complete nuclear internal transcribed spacer (ITS) region and part of the plastid matK gene. Based on this analysis, we selected some terminals for a second analysis using the dataset of Pedron et al (2014), including some species addressed in later studies (Batista et al 2014(Batista et al , 2016(Batista et al , 2017Cruz-Lustre et al 2022;Lau et al 2021) and 37 new sequences from 11 species (12 terminals) that were generated for this study. For the outgroup, encompassing old world taxa, we used the same dataset as Batista et al (2022a), which consists of a selected sampling based on the studies of Jin et al (2017) and Ngugi et al (2020), comprising representatives of the main clades of Asian and African Habenaria and related genera.…”
