Abstract
The herbarium of Joseph Bornmüller (1862–1948) was acquired by the Berlin Botanical Museum in 1938 and belongs today to its most valuable possessions. Parts of Bornmüller´s Hieracium collection remained in the museum´s backlog and have now been incorporated in the general herbarium. A list of Hieracium names published by various authors on the basis of plant material collected by Bornmüller or deposited in Bornmüller´s herbarium is presented here, including information on the type localities given in the protologues. The type material available is listed with full label data and other particulars to be found on the specimens. The status of the type specimens is discussed and the currently accepted names are provided. The names Hieracium fridae-bornmuelleriae and H. scitulum subsp. aquae-albae are validated, the new combinations H. bifidum subsp. arnstadtense, H. diaphanoides subsp. leptodermum, H. glaucinum subsp. chrysoprasicola, and H. schmidtii subsp. trichocyaneum are proposed, and 95 names are lectotypified.
