This volume treats the microscopic anatomy of vegetative organs of two monocotyledonous flowering plant families. Observations are included for Acorus, sole genus of Acoraceae, and nearly all of the 106 genera of the family Araceae, now including the duckweeds as the subfamily Lemnoideae.
The introduction reviews all aspects of morphology and anatomy of the families and a variety of other topics including biogeography, the paleobotanical record, economic uses, chemistry and toxic properties. Highlights of the vegetative anatomical literature are reviewed from about 1000 references...

Contributions to this volume review, in international perspective, the "European social model" of collective bargaining, minimum wages, employment rights, and social welfare support, which is seen as both cause and cure for joblessness and low-wage employment in Europe.

This book is the eagerly-awaited result of over 30 years of research into orchid anatomy by one of the world's leading authorities and is the first comprehensive publication on orchid anatomy since 1930. It describes the structure and relationships among the cells and tissues of leaves, stems, and roots, and is organized systematically in line with the taxonomy expressed in the OUP Genera...
