A Taxonomically-verified and Vouchered Checklist of the Vascular Plants of the Republic of Guinea.

The Checklist of the Vascular Plants of the Republic of Guinea (CVPRG) is a specimen-based, expert-validated knowledge product, which provides a concise synthesis and overview of current knowledge on 3901 vascular plant species documented from Guinea (Conakry), West Africa, including their accepted names and synonyms, as well as their distribution and status within Guinea (indigenous or introduced, endemic or not). The CVPRG is generated automatically from the Guinea Collections Database and the Guinea Names Backbone Database, both developed and maintained at the Royal Botanic Gardens, Kew, in collaboration with the staff of the National Herbarium of Guinea. A total of 3505 indigenous vascular plant species are reported of which 3328 are flowering plants (angiosperms); this represents a 26% increase in known indigenous angiosperms since the last floristic overview.

A 313 plastome phylogenomic analysis of Pooideae: Exploring relationships among the largest subfamily of grasses.

In this study, we analyzed 313 plastid genomes (plastomes) of Poaceae with a focus on expanding our current knowledge of relationships among the subfamily Pooideae, which represented over half the dataset (164 representatives). In total, 47 plastomes were sequenced and assembled for this study. This is the largest study of its kind to include plastome-level data, to not only increase sampling at both the taxonomic and molecular levels with the aim of resolving complex and reticulate relationships, but also to analyze the effects of alignment gaps in large-scale analyses, as well as explore divergences in the subfamily with an expanded set of 14 accepted grass fossils for more accurate calibrations and dating.

A phylogeny of species near supporting the recognition of two new genera, and (Poaceae, Pooideae, Agrostidinae) from Europe.

Based on a molecular DNA phylogeny of three plastid (, intron, and ) and nuclear ITS regions investigating 32 species of Agrostidinae, we describe two new genera, with a single species and with four species; provide support for five species in a monophyletic ; and include a small sample of 12 species of a monophyletic s.s. (including the type and most species of ), that separates into two clades corresponding to A.

Phylogeny of the tribe Aveneae (Pooideae, Poaceae) inferred from plastid trnT-F and nuclear ITS sequences.

New insights into evolutionary trends in the economically important oat tribe (Aveneae) are presented. Plastid trnT-F and nuclear ribosomal ITS sequences were used to reconstruct the phylogeny of the Aveneae-Poeae-Seslerieae complex (Pooideae, Poaceae) through Bayesian- and maximum parsimony-based analyses, separately and in combination. The plastid data identified a strongly supported core Aveneae lineage that separated from other former Aveneae and Poeae groups.
