Acta Botanica Register 11-20. (1976)
Introduction
INTRODUCTION The register of the first ten volumes (1954 — 64) of the Acta Botanica Academiae Scientiarum Hungaricae was published in 1965, containing the bibliographical data of the volumes, the list of the papers arranged according to authors and to subjects and finally the list of the described new taxa. Having published the twentieth volume of the Acta Botanica Hungarica, we submit the register of volumes 11 — 20, arranged as the former one. The ten volumes considered amount to 4274 pages with 52 plates — including 4 coloured ones — and 23 tables. They contain 295 original papers with 3557 illustrations by 208 authors (90 of them abroad). In volumes 11 — 20, there are described 717 new taxa (resp. new names) in the following distribution: 100 algae, 5 mushrooms, 15 mosses, 2 pteridophytes, 476 angiosperms, 73 fossil pollens and spores, and 46 fossil plants. To make a comparison between the corresponding dates of the first and second ten volumes it appears that the second ten volumes — though an fewer pages — contain more papers and illustrations. The increments expressed in percentages are: papers 28%, authors 63%, illustrations 56%, while the number of described new taxa has grown by 140%. The register (like the previous one) is not only a summarized content of the ten volumes, but it comprises more bibliographical information than the single contents of volumes 11 — 20. It has the same structure as the register to volumes 1 — 10, except the new department, the book review (started in 1968). In addition, it has been necessary — owing to the much greater number of articles — to make an different or more detailed subject index. Part I gives the bibliographical data of volumes 11 — 20, with the actual publication dates of the single fascicles. Part II enumerates all published articles in the alphabetical order of their authors, referring also to coauthors and to the double family-name of the authoresses. Part III lists book rewiews an alphabetical order referring to the authors of the reviewed books. Part IV collects the data of Part II, according to the various botanical disciplines. Finally, Part V gives the list of the described new taxa and of the new names (omitting the new combinations) in a systematical sequence.
