Data from: Phylogeny of digitaria sections Trichachne and Trichophorae (Poaceae, Panicoideae, Paniceae): a morphological and molecular analysis. New circumscription and synopsis
The present study provides evidence for taxonomic delimitation of Digitaria sect. Trichachne based on morphological data (micro- and macromorphology) and molecular data. A phylogenetic analysis was performed using 121 morphological characters and ITS sequences of 22 species and one variety of Digitaria plus three outgroups. In all topologies (based on morphological, molecular, and combined data) Digitaria sect. Trichophorae was non-monophyletic and nested within D. sect. Trichachne. Digitaria sect. Trichophorae is thus synonymized under D. sect. Trichachne and the circumscription of D. sect. Trichachne is emended. Diagnostic morphological characters related to spikelet structure are described and documented with SEM. A key to taxa belonging to D. sect. Trichachne is provided, as well as a synopsis including synonymy, iconography, geographical distribution, and ecology. The neotype of Trichachne sacchariflora Nees is herein designated. Complete illustrations of Digitaria eggersii, D. hitchcockii, and D. patens are provided. The phylogenetic placement of the Australian species D. brownii differed among trees resulting from different data sets, thus it is provisionally not included in D. sect. Trichachne in spite of its morphological similarity. Furthermore, Megaloprotachne albescens is formally transferred to Digitaria, as Digitaria albescens .

Data from: Whole chloroplast genome and gene locus phylogenies reveal the taxonomic placement and relationship of Tripidium (Panicoideae: Andropogoneae) to sugarcane
Background: For over 50 years, attempts have been made to introgress agronomically useful traits from Erianthus sect. Ripidium (Tripidium) species into sugarcane based on both genera being part of the 'Saccharum Complex', an interbreeding group of species believed to be involved in the origins of sugarcane. However, recent low copy number gene studies indicate that Tripidium and Saccharum are more divergent than previously thought. The extent of genus Tripidium has not been fully explored and many species that should be included in Tripidium are still classified as Saccharum. Moreover, Tripidium is currently defined as incertae sedis within the Andropogoneae, though it has been suggested that members of this genus are related to the Germainiinae. Results: Eight newly-sequenced chloroplasts from potential Tripidium species were combined in a phylogenetic study with 46 members of the Panicoideae, including seven Saccharum accessions, two Miscanthidium and three Miscanthus species. A robust chloroplast phylogeny was generated and comparison with a gene locus phylogeny clearly places a monophyletic Tripidium clade outside the bounds of the Saccharinae. A key to the currently identified Tripidium species is presented. Conclusion: For the first time, we have undertaken a large-scale whole plastid study of eight newly assembled Tripidium accessions and a gene locus study of five Tripidium accessions. Our findings show that Tripidium and Saccharum are eight million years divergent, last sharing a common ancestor 12 million years ago. We demonstrate that four species should be removed from Saccharum/Erianthus and included in genus Tripidium. In a genome context, we show that Tripidium evolved from a common ancestor with and extended Germainiinae clade formed from Germainia, Eriochrysis, Apocopis, Pogonatherum and Imperata. We re-define the 'Saccharum complex' to a group of genera that can interbreed in the wild and extend the Saccharinae to include Sarga along with Sorghastrum, Microstegium vimineum and Polytrias (but excluding Sorghum). Monophyly of genus Tripidium is confirmed and the genus is expanded to include Tripidium arundinaceum, Tripidium procerum, Tripidium kanashiroi and Tripidium rufipilum. As a consequence, these species are excluded from genus Saccharum. Moreover, we demonstrate that genus Tripidium is distinct from the Germainiinae.
