TYPIFICATION OF CACHRYS LIBANOTIS L. (UMBELLIF.)

Summary C. libanotis , the type species of the monotypic Linnaean genus Cachrys , is proved to comprise 2 genera: Cachrys L. (incl. Prangos Lindl.) and Hippomarathrum Link non P.G. Gaertn., B. Mey. & Scherb. The relevant literature and possible type specimens are discussed. A Burser specimen (with ripe fruits), seen by Linnaeus and determined by him as C. libanotis , is chosen as the best admissible lectotype. This specimen agrees with Cachrys trifida Mill. to which, therefore, the name C. libanotis has to be reinstated. As a result of this typification the generic name Cachrys L. may be retained for the taxa conventionally considered as Cachrys L. or Prangos Lindl., while Hippomarathrum Link, being a later homonym, is proposed for conservation.
