This paintings, released in volumes, includes descriptions of the wooden and bark anatomies of 3000 dicotyledonous vegetation of one hundred twenty households, highlighting the anatomical and phylogenetic range of dicotyledonous crops of the Northern Hemisphere. The first volume largely treats households of the Early Angiosperms, Eudicots, middle 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 timber of 1200 species and eighty five households of assorted existence varieties of the temperate region alongside altitudinal gradients from the lowland on the Mediterranean coast to the alpine sector in Western Europe. the worldwide point of view of the findings is underlined through the research of 500 species from the Caucasus, the Rocky Mountains and Andes, the subtropical region at the Canary Islands, the arid zones within the Sahara, in Eurasia, Arabia and Southwest North the USA, and the boreal and arctic zones in Eurasia and Canada.

The presence of annual earrings in all lifestyles varieties demonstrates that herbs and dwarf shrubs are a good 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 edition techniques 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 crucial eu controlled forests. The examine opens immense fields of analysis for dendrochronology, wooden anatomy, taxonomy and ecology.

9) in rays of many species and vertical ducts in the pith (Fig. 13 and 14).  1. Ring-porous xylem with distinct annual rings. Latewood vessel-groups are in diagonal patterns. Stem of a 2 m-high shrub, on limestone rock, hill zone, Trento, Italy. Cotinus coggygria, transverse section.  2. Distinct annual rings in a ringporous xylem with few earlywood vessels. Small vessels and vascular tracheids are mostly in radial groups. Stem of a 2 mhigh shrub, maccia, Mediterranean zone, Cevennes, France. Pistacia terebinthus, transverse section.

141.  142.  143.  144. 110 Rays with sheet cells (tangential section). Cells located along sides of broad rays, larger than central ray cells. 117 Rayless wood only with axial elements. Identification of this feature is only possible using tangential sections. In cross-sections ray cells with the same form as fibers or parenchyma can be mistaken for ray absence.  146. Umbilicus horizontalis, Crassulaceae, herb. With short, thin-walled, lignified fibers.  147. Silene viscaria, Caryophyllaceae, herb.

The present study, however, differs from the previous studies: Most previous authors, with the exception of Heklau (1992), concentrated on the xylem of shrubs and dwarf shrubs from dry regions. This study includes many herbaceous species including those in humid regions. The absence of fibres and the presence of pervasive parenchyma is characteristic of some herbaceous species. Some species contain prismatic crystals. The pith has hardly been observed. Only Carlquist (2003) described the pith of 2 species (Amaranthus caudatus and Nototrichium sandwicense).
