Handbuch der Pflanzenanatomie. Encyclopedia of plant anatomy. Traité d'anatomie végétale / Anatomie des Galles

This work on the anatomy of galls (phytocecidia and zoocecidia) succeeds KÜSTER'S which appeared in 1930 in the same series, 'Handbuch der Pflanzenanatomie'. Despite the value of the latter, a new work was necessary to include recent findings and new theories in cecidology which have evolved in the last half century since publication of the first work. While retaining the essentials of the old work, the new work condenses past findings and leaves adequate scope for the presentation of new findings. This new and comprehensive work is based on a bibliography of 493 works of reference and provides an index of gall-forming parasites comprising 438 species, genera and families and an index of hosts listing 347 names. It is magnificently and generously illustrated, with 519 figures, most of which are microphotographs taken with a light or electron microscope. This work highlights the specific nature of gall-forming parasites and the organizing role played by cecidozoa, decisive for the anatomy of the gall hosting it -- the perfect adaptation of the plant to the parasite, permitting the realization of the latter's biological cycle and indispensable for conserving the gall-forming species. These structures are all described and illustrated in detail on the basis of the most recent works on this subject.
