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 an...

... 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;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. ...
A phylogenomic analysis of the so far phylogenetically unresolved subfamily Bromelioideae (Bromeliaceae) was performed to infer species relationships as the basis for future taxonomic treatment, stabilization of generic concept, and further analyses of evolution and biogeography of the subfamily. A target-enrichment approach was chosen, using the Angiosperms353 v.4 kit RNA-baits and including 86 Bromelioideae species representing previously identified major evolutionary lineages. Phylogenetic analyses were based on 125 target nuclear loci, assembled off-target plastome as well as mitogenome reads. A Bromelioideae phylogeny with a mostly well-resolved backbone is provided based on nuclear (194 kbp), plastome (109 kbp), and mitogenome data (34 kbp). For the nuclear markers, a coalescent-based analysis of single-locus gene trees was performed as well as a supermatrix analysis of concatenated gene alignments. Nuclear and plastome datasets provide well-resolved trees, which showed only minor topological in-congruences. The mitogenome tree is not sufficiently resolved. A total of 26 well-supported clades were identified. The genera Aechmea, Canistrum, Hohenbergia, Neoregelia, and Quesnelia were revealed polyphyletic. In core Bromelioideae, Acanthostachys is sister to the remainder. Among the 26 recognized clades, 12 correspond with currently employed taxonomic concepts. Hence, the presented phylogenetic framework will serve as an important basis for future taxonomic revisions as well as to better understand the evolutionary drivers and processes in this exciting subfamily.
