<p><strong>A new species of <em>Androlepis </em>(Bromelioideae; Bromeliaceae), endemic from southern Megamexico</strong></p>

Abstract

Androlepis najarroi (Bromelioideae, Bromeliaceae), a third dioecious species identified in the subfamily, is proposed as new from the Chiapas Highlands and Veracruzan biogeographical provinces, southern Megamexico. The novelty is superficially similar to Aechmea lueddemanniana but features characteristics of Androlepis, such as unisexual flowers and apically divided filaments. Based upon available information on the species and current generic concepts, assigning this species to Androlepis might only be provisional. The present contribution includes distribution maps, iconography, an identification key to the species of Androlepis, and a preliminary evaluation of the conservation status of this new species.

Target‐enrichment sequencing reveals for the first time a well‐resolved phylogeny of the core Bromelioideae (family Bromeliaceae)

“…This genetically very well‐defined clade has also been found in previous studies with relevant sampling and resolution (Schulte & al., 2005; Horres & al., 2007; Schulte & Zizka, 2008; Schulte & al., 2009; Sass & Specht, 2010; Silvestro & al., 2014; Díaz, 2019). From the morphological point of view, the members of this clade are strikingly different (Ramirez‐Diaz & al., 2020). However, the consistent results of molecular phylogenetic studies very much contradict the current taxonomy.…”

Re-establishment of Aechmea laxiflora (Bromeliaceae, Bromelioideae) based on morphological and phylogenetic evidence, with notes on its geographical distribution

“…pacifica (three sampled individuals) possessed reciprocal monophylly, being each taxa recovered as monophyletic with respect to each other (Kizirian & Donnelly 2004); however, according to cpDNA evidence, A. bracteata var. pacifica seems to be more related to A. pittieri and A. pubescens (Ramírez-Díaz 2019), but this relationship is not well supported since the topology shows low resolution.…”

“…Later, Ramírez-Díaz (2019) performed a phylogenetic analysis in order to assess the phylogenetic position of Mexican and Central American distributed Bromelioids. This work included a phylogenetic analysis with the same markers used by Sass & Specht (2010) but with a higher number of species (210 spp.…”

“…), as well as individual analyses for nDNA markers (agt1 and g3pdh) and cpDNA markers (rpl32-trnL and ycf1) with fewer species but with several specimens per taxa to test the monophyly of various clades and species complexes. All the analyses by Ramírez-Díaz (2019) retrieved the monophyly of the Central American Clade II (sensu Sass & Specht 2010). According to the nDNA evidence by Ramírez-Díaz (2019), A. bracteata var.…”

“…All the analyses by Ramírez-Díaz (2019) retrieved the monophyly of the Central American Clade II (sensu Sass & Specht 2010). According to the nDNA evidence by Ramírez-Díaz (2019), A. bracteata var. bracteata (four sampled individuals) and A. bracteata var.…”
