This fileset includes a curated, reduced version of the matrix used by Soltis et al. (2011) that I generated in 2012 for a colleague at the Swedish Museum of Natural History, who was looking for plant matrices that can be used for total-evidence dating. The experiment failed, and the project was abondoned (see Footnote 7 of the linked post).

The taxon set was reduced to match the set used in Sareela et al. (2007), respectively Doyle & Endress (2010).

The final matrix combines data from placeholder-genera and well-covered gene regions (nuclear-encoded 18S rDNA, 25S rDNA; mitochondrial atp1, matR, nad5; plastid atpB, matK, ndhF, psbB...psbH, rbcL, rpoC2) and corresponding morphological data as extra partition.

— An 7z-archive ( including the matrices, a fully annotated version generated with and optimised for Mesquite ( and a simple-NEXUS version for MrBayes.
— Several draft graphs as PDF: a ML tree inferred from the matrix (bootstrap support annotated) with RAxML (00all.ML...); a Bayesian total evidence generated with MrBayes by my colleague (01b.withFossils....); a neighbour-net based on morphological distance inferred from the morphological partition in the combined matrix.
— A tabulation of the checked data, with some curating information, in two formats: CSV (for general compatibility), and xlsx (for further functionality, includes summarising Pivot-table)
— Additional figures (v. 2) shown in blogposts using this matrix or subsets of it (see provided links)
