Molecular Phylogenetics and Trait Evolution in Stigmatodon (Bromeliaceae, Tillandsioideae), an Endemic Genus to Brazilian Rocky Outcrops
<p><strong><em>Abstract</em></strong>—The genus <em>Stigmatodon</em> occurs in steep granite slopes, typical of the inselbergs from the Brazilian Atlantic Forest. Here, we present the first broad phylogenetic analysis focused on <em>Stigmatodon</em>, sampling a total of 83 terminals, including 16 of the 20 species of the genus and the morphologically similar species of <em>Vriesea</em>. We conducted a phylogenetic analysis using two plastid markers (<em>matK </em>and <em>rps16-trnK</em>) and the nuclear gene <em>PHYC</em> to infer phylogenetic relationships and reconstruct ancestral states for ecological and morphological characters. Our results suggest the monophyly of <em>Stigmatodon</em> as originally circumscribed is only possible with the inclusion of morphologically and ecologically similar <em>Vriesea</em> species. In addition, the morphological and anatomical traits led us to propose a new circumscription for the genus, combining eight species of <em>Vriesea </em>to <em>Stigmatodon</em>. The stomata positioned above the ordinary epidermal cells, the adaxial water-storage parenchyma with axially elongated cells, the stamens positioned in two groups of three on each side of the corolla and the tubo-laciniate stigma are exclusive to <em>Stigmatodon</em> in its new circumscription. This new morphological and phylogenetic results constitute a relevant contribution to the taxonomy and evolution of Bromeliaceae, one of the most diverse and ecologically important families of flowering plants of the Neotropics.</p>
Phylogenetic study of the New Caledonian endemic genus Adenodaphne (Lauraceae) confirms its synonymy with Litsea
<p>The genus <em>Adenodaphne</em> is currently considered endemic to New Caledonia, but its distinction from Litsea is questionable based on morphological similarity. An earlier phylogenetic analysis (ITS) including one species of <em>Adenodaphne</em> and two Asian species of <em>Litsea</em> did support their close relationship but did not permit resolution of their generic boundary. We sampled the four species of <em>Adenodaphne</em> currently recognized (11 accessions) and 11 of the 13 endemic species of <em>Litsea</em> currently recognized, plus one undescribed species (24 accessions in total). Based on our extensive herbarium studies, field work, and especially our molecular phylogenetic analyses (ITS) we conclude that <em>Adenodaphne</em> is not distinct from <em>Litsea</em> and that all species of <em>Adenodaphne</em> should be recognized within <em>Litsea</em>, thereby necessitating the creation of two new species synonymies and one nomen novum. As well, <em>Litsea</em> paoueensis is here synonymized with L. deplanchei.</p> <p><span></span></p>
Description of two new species and phylogenetic placement of recent taxonomic novelties in the Chilean endemic genus Miersia (Gilliesieae, Allioideae, Amaryllidaceae)
<p>Abstract: Two new species in the Chilean endemic genus <em>Miersia</em> (Gilliesieae, Allioideae, Amaryllidaceae) are introduced: <em>M. stellata</em> and <em>M. raucoana</em>. A morphological description, distribution map, illustration, and the assessment of their conservation status are provided for each new taxon, along with an updated key to all species in <em>Miersia</em>. Additionally, analyses of DNA sequences were performed to inquire the evolutionary affinities of both new species and the recently described, <em>M. putaendensis</em>, within Gilliesieae phylogenetic framework. Data from multiple single-copy nuclear genes, as well as the inclusion of <em>Trichlora</em> and <em>Schickendantziella</em>, are necessary to corroborate the tribe’s phylogeny and reassess its generic classification.</p> <p>Dataset description: Two phylip alignment files were uploaded: 1) Miersia_nov_ITS_3.0.phy, includes sequences of nrDNA ITS (nrITS) region, and 2) Miersia_nov_cpDNA_3.0.phy, includes concatenated sequences of two chloroplast (cpDNA) markers, <em>trnL-F</em> and <em>rbcL</em>. Sequences were aligned using MAFFT v.1.4.0.</p> <p>Three *.bestTree.tre files for 1) nrITS, 2) cpDNA, and 3) concatenated dataset of all loci (nrITS, <em>trnL-F</em>, <em>rbcL</em>). All were inferred using RAxML-NG v.1.1.0 (Kozlov et al. 2019), GTR+Γ as the model of molecular evolution (--model GTR+G), and partitioned by locus. nrITS and cpDNA analyses were performed conducting 50 tree searches using 25 random and 25 parsimony-based starting trees to pick the best-scoring topology (--tree pars{25},rand{25}), and the concatenated analysis included 100 tree searches using 50 random and 50 parsimony-based starting trees (--tree pars{50},rand{50}). </p> <p>Also, the respective boostrap trees (*.bootstraps.tre) were uploaded for each analysis. Likelihood bootstrap analyses were conducted in RAxML-NG v.1.1.0 with 1,000 pseudoreplicates (--bs-trees 1000).</p> <p>We also uploaded two Nexus files which correspond to sequence data from Escobar et al. (2020, Bot. J. Linn. Soc. 194: 84–99), considering that these are currently not available in TreeBase.</p>

Alignments and phylogenetic tree from: A new endemic species of Loasa ser. Macrospermae from northern Chile
<p><span></span></p> <p>Alignments used for the phylogenetic work and raw phylogenetic trees obtained.</p> <p>A new species of Loasa, endemic to the northern Andes of Chile is described and evaluated, under the IUCN criteria for conservation, as critically endangered. Molecular analyses based on plastid markers place the new species within the Loasa ser. Macrospermae, with high support, and specifically as sister to Loasa acerifolia. A key to and comparative plates including all the 13 known species of Loasa ser. Macrospermae, are provided.</p>
