Valid publication of names in Astereae originally proposed in 1990 in a University of Munich dissertation

摘要

The new species names Mairia petiolata,Zyrphelis capensis, Z. glabra,Z. glandulosa,Z. grauii,Z. macrocarpa,Z. nervosa, Z. spathulata, the new subspecies names Mairia hirsuta subsp. robusta, Zyrphelis ecklonis subsp. oligocephala,Z. ecklonis subsp. strictifolia, Z. microcephala subsp. foliosa, Z. microcephala subsp. glandulosa and the new combinations Zyrphelis ciliaris,Z. ciliaris subsp. angustifolia,Z. ciliaris subsp. hirsuta,Z. decumbens,Z. fruticosa,Z. gracilis,Zyrphelis sect. Gymnostephium, Z. leiocarpa, Z. levis, Z. montana, Z. monticola, and Z. outeniquae are validly published. These names originally appeared in the Ph.D. thesis of the second author, Ursula Zinnecker-Wiegand, submitted to the University of Munich, Germany, in 1990. Being printed and distributed to over 50 libraries, this thesis met the formal requirements for effective publication of the International Code of Botanical Nomenclature then in force, but it is no longer effectively published as a result of a retroactive change in the rules adopted at the International Botanical Congress in Vienna in 2005. As result, the new names appearing in the thesis were not validly published and they are validated here.
