For assessment of own chromosome counts in Hieracium was carried out a literature survey of the chromosome numbers of Hieracium reported in the standard abstracting references. This surely not complete compilation (updated until may 1, 1996) will be continued and additions and/or corrections are accepted with pleasure: Email schuhwerk@snsb.de.
Pugsley (1948: 19) characterizes the system adopted by Zahn "of often very large capital species" as "the best that can be devised for an account of the whole genus". Therefore this compilation follows the system of Zahn as the greater part of mentions of taxa in the literature evaluated here. In the monographs of Zahn not mentioned taxa are treated after Sell & West in "Flora Europaea". Scandinavian, British or Russian "microspecies" are here related to species of Zahn unless proposing new combinations. Changes of names required by the rules of ICBN are not carried out here if not a type of the correct name was seen.
Bibliographical data (mostly in the form as in abstracting references) of cited chromosome counts are compiled in Literature. To my regret I have not found some special signs and accents used in Russian or other Slavic languages for HTML.
Chromosome counts in Hieracium are also found e. g. in a data base compiled by Missouri Botanical Garden.
