Molecular phylogeny and morphological perianth evolution in Corymbia (Myrtaceae), and the implications for generic delimitation: data and tree files
<p><strong>Premise:</strong> Eucalypts (Myrtaceae tribe Eucalypteae) are currently placed in seven genera. Traditionally,<em> Eucalyptus</em> was defined by its operculum but when phylogenies placed <em>Angophora</em>, with free sepals and petals, as sister to the operculate bloodwood eucalypts, the latter were segregated into a new genus, <em>Corymbia</em>. Yet generic delimitation in the tribe Eucalypteae remains uncertain. Here we address these problems using phylogenetic analysis with the largest molecular dataset to date.</p> <p><strong>Methods: </strong>We captured 101 low-copy nuclear exons from 392 samples representing 266 species. Our phylogenetic analysis used maximum likelihood (IQtree) and multi-species coalescent (Astral). At two nodes critical to generic delimitation, we tested alternative relationships among <em>Arillastrum</em>, <em>Angophora</em>, <em>Eucalyptus</em> and <em>Corymbia</em> using Shimodaira's AU test. Phylogenetic mapping was used to explore the evolution of perianth traits.</p> <p><strong>Results: </strong>Monophyly of <em>Corymbia</em> relative to <em>Angophora</em> was decisively rejected. All alternative relationships among the seven currently recognised Eucalypteae genera imply homoplasy in evolutionary origins of the operculum. Inferred evolutionary transitions in perianth traits are congruent with divergences between major clades except that expression of separate sepals and petals in <em>Angophora</em>, which is nested within the operculate genus <em>Corymbia</em>, appears to be a reversal to the plesiomorphic perianth structure.</p> <p><strong>Conclusions:</strong> Here we formally raise <em>Corymbia</em> subg. <em>Blakella</em> to genus rank and make the relevant new combinations. We also define and name three sections within <em>Blakella</em> (<em>B.</em> sect. <em>Blakella</em>, <em>B.</em> sect. <em>Naviculares</em> and <em>B.</em> sect. <em>Maculatae</em>), and two series within <em>Blakella</em> sect. <em>Maculatae</em> (<em>B.</em> ser. <em>Maculatae</em> and <em>B.</em> ser. <em>Torellianae</em>). <em>Corymbia</em> is reduced to the red bloodwoods.</p>

Phylogenomic analysis of the hemp family (Cannabaceae) reveals deep cyto-nuclear discordance and provides new insights into generic relationships
<p>Cannabaceae are a relatively small family of angiosperms, but they include several species of huge economic and cultural significance: marijuana or hemp (Cannabis sativa) and hops (Humulus lupulus). Previous phylogenetic studies clarified most deep relationships in Cannabaceae, but relationships remain ambiguous among several major lineages. Here, we sampled 83 species representing all genera of Cannabaceae and utilized a new dataset of 90 nuclear genes and 82 chloroplast loci from Hyb-Seq to investigate the phylogenomics of Cannabaceae. Nuclear phylogenetic analyses revealed a robust and consistent backbone for Cannabaceae. We observed nuclear gene-tree conflict at several deep nodes in inferred species trees, also cyto-nuclear discordance concerning the relationship between Gironniera and Lozanella and the relationships among Trema s.l. (including Parasponia), Cannabis + Humulus, and Chaetachme + Pteroceltis. Coalescent simulations and network analyses suggest that observed deep cyto-nuclear discordances likeliest stem from incomplete lineage sorting (ILS); nuclear gene-tree conflict might be caused by both ILS and gene flow between species. All genera of Cannabaceae were recovered as monophyletic, except for Celtis, which consisted of two distinct clades: Celtis I (including most Celtis species) and Celtis II (including Celtis gomphophylla and Celtis schippii). We suggest that Celtis II should be recognized as the independent genus Sparrea based on both molecular and morphological evidence. Our work provides the most comprehensive and reliable phylogeny to date for Cannabaceae, enabling further exploration of evolutionary patterns across this family and highlighting the necessity of comparing nuclear with chloroplast data to examine the evolutionary history of plant groups.</p>
