ABSTRACT:

Recently Crusio (1979) published a revision of the African aroid genus Anubias Schott. Simultaneously to his investigations of an analysis of the somatic chromosome numbers of the various species was initiated by the present authors. It appeared however that the chromosomes of Anubias are rather difficult to handle; well spread metaphase plates permitting conclusive counts are rare. At the time Crusio completed his revision there were many uncertainties in respect to the correct chromosome numbers of several plant specimens. Moreover, not all species as recognized by Crusio were available for investigation. Since that time several more species were acquired with the result that a complete chromosomal analysis can now be presented.
