<div>This file set contains (version 2) information, and analysis files, related to morphological data matrices collected from literature (including some we published) to sum up some principal features of these matrices, mainly how tree(un)like they are.</div><div><br></div><div>Version 2 includes<br></div><div><b>XLXS-File <i>OverviewTables</i> </b>summarising general signal information (behaviour under parsimony and NJ tree-building in relation to matrix and individual Delta Values, a measure for treelikeness.</div><div><b> </b></div><div><br></div><div><b>7z-Archives <i>Cycadales </i></b>and <i><b>HuffordMcMahon</b></i>.</div><div><i><b>Cycadales.7z</b> </i>includes the matrices of Stevenson (<i>Mem.
