An update of the “Catalogue of the Hedwig-Schwägrichen Herbarium (Part 1)” of 2005 has been compiled herein. It collates the 38 recently published typifications for the Hedwig moss names and includes updated information on 12 typifications that were unintentionally omitted or incorrectly cited in the original catalogue. Information on the place and page of publication of each typification as well as the details of the types themselves is given for each name concerned. Given the complexities of the typification process of the Hedwig material (for example, the historical nature of the material, presence of different entities with different temporal or geographic origins on the type sheet, two or more species attached to the same sheet, the presence of Schwägrichen's annotations, labels that do not correspond exactly with the protologue or validating description) the correct citation of the G-Hedwig herbarium sheet and of the elements on it being typified are of crucial importance. To facilitate the unequivocal identification of the Hedwig specimens in G a list of the barcodes assigned to each of the Hedwig herbarium sheets figured in the original catalogue is provided.
