This book represents a response to the action plan for Diospyros and Dalbergia species regarding the establishment of a reference collection and reliable identification system for species listed by CITES, the Convention on International Trade in Endangered Species of Wild Fauna and Flora.

This atlas gives a unique assemblage of microscopic slides of wood anatomy and and demonstrates the reaction of stem anatomy to environments in which plants form woody stems. Presented in color throughout it has over 700 beautiful and instructive illustrations.

The global perspective of the findings is underlined by the analysis of 500 species from the Caucasus, the Rocky Mountains and Andes, the subtropical zone on the Canary Islands, the arid zones in the Sahara, in Eurasia, Arabia and Southwest North America, and the boreal and arctic zones in Eurasia and Canada.

This atlas presents anatomical descriptions of the xylem, bark and pith of more than 260 species belonging to over 65 families. It highlights the anatomical diversity found in the Eastern Mediterranean region, with a focus on the island of Cyprus.

At a meeting of dendrochronologists an American colleague described the effects of volcanic eruptions on annual ring formation in bristlecone pines. It is difficult even for dendrochronol ogists to keep in touch with the whole spectrum, and even more difficult for the layman to obtain an overall view of the many methods and fields of application.

This work, published in two volumes, contains descriptions of the wood and bark anatomies of 3,000 dicotyledonous plants of 120 families, highlighting the anatomical and phylogenetic diversity of dicotyledonous plants of the Northern Hemisphere.
