Popis: | Anderberg, Arne A. (Swedish Museum of Natural History, Department of Phanerogamic Botany, p.o. Box 50007, S-104 05 Stockholm, Sweden) 1992. In defence of the transfer of Nablonium to Ammobium (Asteraceae-GnaphaIieae), a reply to Orchard. Telopea 5(1): 13-19. The relationship between Ammobium (2 species) and Nablonium (1 species) has once again been examined. A cladistic parsimony analysis has been undertaken based on the data presented in support of an alternative taxonomic treatment (Orchard this volume). The result of the analysis is illustrated with a cladogram. It is concluded that Ammobium is paraphyletic, and the problem with paraphyletic groups is discussed. Ammobium calyceroides (= Nablonium calyceroides) and Ammobium craspedioides are sister species, and most similarities between A. craspedioides and A. alatum are symplesiomorphies. |
