This paintings, released in volumes, includes descriptions of the wooden and bark anatomies of 3000 dicotyledonous crops of a hundred and twenty households, highlighting the anatomical and phylogenetic range of dicotyledonous crops of the Northern Hemisphere. The first volume mostly treats households of the Early Angiosperms, Eudicots, center Eudicots and Rosids, whereas the second one concentrates at the Asterids.

Presented in Volume 1 are microsections of the xylem and phloem of herbs, shrubs and bushes of 1200 species and eighty five households of assorted existence different types of the temperate region alongside altitudinal gradients from the lowland on the Mediterranean coast to the alpine area in Western Europe. the worldwide viewpoint of the findings is underlined via the research of 500 species from the Caucasus, the Rocky Mountains and Andes, the subtropical quarter at the Canary Islands, the arid zones within the Sahara, in Eurasia, Arabia and Southwest North the United States, and the boreal and arctic zones in Eurasia and Canada.

The presence of annual jewelry in all existence varieties demonstrates that herbs and dwarf shrubs are a great instrument for the reconstruction of annual biomass creation and the interannual dynamic of plant institutions. the typical precept of the anatomical expression of secondary development is a key consider realizing evolution and version strategies in all lifestyles types, from the two cm tall whitlow grass (Draba arctica) within the arctic to the forty m tall beech (Fagus sylvatica) in imperative eu controlled forests. The research opens massive fields of analysis for dendrochronology, wooden anatomy, taxonomy and ecology.
