Data from: A multi-locus plastid phylogeny of the Aulonemia clade (Poaceae: Bambusoideae: Bambuseae: Arthrostylidiinae) reveals three new genera of bamboo
<p>Arthrostylidiinae (Poaceae: Bambusoideae), a subtribe of Neotropical woody bamboos with diverse morphology, comprises 200 species classified in 16 genera. Previous studies supported monophyly of the subtribe and recovered four major internal clades, however, some genera were found to be polyphyletic while others, like <em>Aulonemia</em> and <em>Colanthelia,</em> were either undersampled or not included. <em>Aulonemia</em> and <em>Colanthelia</em> are complex both in their taxonomy and morphology, and exhibit overlapping morphological characters. Prior morphological and molecular analyses suggested they share a close relationship, with <em>Colanthelia </em>emerging as monophyletic and either nested within <em>Aulonemia</em> or sister to it,<em> </em>but these studies sampled relatively few species of each genus. The aims of this study were to increase taxon sampling to test the monophyly of <em>Aulonemia</em> and <em>Colanthelia, </em>to investigate the relationships within the <em>Aulonemia </em>+ <em>Colanthelia </em>clade, and to revise their classification as appropriate towards a natural classification of the Arthrostylidiinae. We present a multi-locus plastid phylogeny of the Arthrostylidiinae with emphasis on <em>Aulonemia </em>and <em>Colanthelia</em>. We used sequences of seven plastid markers (one coding: <em>ndhF</em>; six non-coding:<em> trnC-rpoB, rps16-trnQ, trnT-trnL, rps16, trnD-trnT, </em>and <em>rpl16</em>) from 67 taxa of Bambusoideae including all genera of Arthrostylidiinae. Phylogenetic trees were inferred using both Bayesian and maximum likelihood methods. <em>Aulonemia</em> was confirmed as polyphyletic and <em>Colanthelia</em> was not supported as monophyletic. The phylogenetic position of <em>Myriocladus </em>within Arthrostylidiinae is resolved for the first time. All species of <em>Colanthelia</em> were recovered within the clade containing most species of <em>Aulonemia</em>. Four species of <em>Aulonemia</em> (<em>A. radiata</em>, <em>A. effusa</em>, <em>A. setosa</em>, and <em>A. setigera</em>) grouped in other clades within the subtribe and these placements combined with morphological evidence support the establishment of three new genera: <em>Quixiume</em>, <em>Stelanemia</em> and <em>Vianaea</em>, to accommodate the four remarkable <em>Aulonemia</em> species. An updated key for the genera of the Arthrostylidiinae is provided, as well as taxonomic treatments for the three new genera, including the description of a new species in <em>Stelanemia</em>.</p>

Plastid phylogenomics shed light on intergeneric relationships and spatiotemporal evolutionary history of Melocanninae (Poaceae: Bambusoideae)
Melocanninae is sister to other subtribes of Paleotropical woody bamboos with some 90 species mainly concentrated in Asia. However, phylogenetic relationships within the subtribe are poorly known. Here, we filled the gaps in complete plastome data of Melocanninae, reconstructed the phylogeny of Melocanninae, and further estimated divergence time and ancestral distribution range. Our results showed that the two major genera, <i>Cephalostachyum </i>and <i>Schizostachyum</i>, were paraphyletic. Species of <i>Cephalostachyum</i> were resolved in two successive basal clades, while <i>Annamocalamus</i> was embedded in the <i>Schizostachyum</i> clade. Different plastid regions provided inconsistent signals for the relationship of <i>Melocanna</i> and <i>Pseudostachyum</i>. Conservative loci supported a successive divergence rather than sister relationship between them and the difference may be caused by long-branch attraction. We infer that Melocanninae originated in the East Himalaya to northern Myanmar in the early Miocene. Three routes were revealed in forming its present biogeographic pattern: <i>in situ</i> diversification on the Asian mainland; dispersing southwest to Sri Lanka and to the Western Ghats in South India; and spreading southeast to Malesia and Oceania via the Indo-China Peninsula. The rapid uplift of the Tibetan Plateau and the intensification of Asian monsoons since the Miocene and the sea-level-fall events since the late Miocene might be potential driving forces for diversification of Melocanninae and, particularly the latter event, for the species radiation of <i>Schizostachyum</i>.
