Wood density relates negatively to maximum plant height across major angiosperm and gymnosperm orders

Data coming from an extensive sampling on species woody tissue densities.For each species, there are columns dedicated to its taxonomic classification plus the volume and weight of 4 woody tissues, including entire (complete stem cross-section), backless (stem cross-section without bark), pithless (stem cross-section with bark and without pith), and wood (stem cross-section without bark and pith).
