Provisional generic delimitation in the Haumaniastrum/Acrocephalus complex (Labiatae)

  • A. Paton


Generic delimitation within the “Acrocephalus group” of genera is discussed using a preliminary cladistic analysis. The African Haumaniastrum and an enlarged Asiatic, Madagascan and African Acrocephalus are recognized at this preliminary stage. Geniosporum as currently delimited is polyphyletic and it is suggested that the genus should not be recognized, its species being placed either in Acrocephalus or Limniboza. It is also proposed to merge Ceratanthus into Platostoma,which is the earlier name. It should be noted that these are preliminary conclusions and that no formal changes are made here.

Key words

Acrocephalus Generic delimitation Geniosporum Haumaniastrum 


Délimitation générique dans le «Acrocephalus group» de genres est discuté en utilisant une analyse cladistique et préliminaire. Le Haumaniastrum Africain et un Acrocephalus agrandi de l’Asie, Madagascar et l’Afrique sont reconnus. Geniosporum comme couramment délimité est polyphyletique et il est suggéré que le genre ne doit pas être reconnu, les espèces étant placées dans Acrocephalus ou Limniboza. C’est aussi proposé à placer Ceratanthus dans Platostoma qui est le nommatinal. On doit noter que celles sont des conclusions préliminaires et qu’on ne fait pas de changements formels ici.
