THE GENUS POTHOS L (ARACEAE-POTHOEAE) IN NEW-GUINEA, SOLOMON-ISLANDS AND AUSTRALIA

The genus Pothos L. is revised for the Australasian region. Twelve species are recognised. Pothos albertisii Engl. and P. quinquevenosus Alderw. are reduced to the synonymy of P. papuanus Becc. ex Engl.; P. brevispatha Ridl. and P. ledermannii Engl. & K. Krause are reduced to the synonymy of P. versteegii Engl.; P. elegans Engl. is reduced to the synonymy of P. zippelii Schott, and P. brownii Domin is reduced to the synonymy of P. longipes Schott. No new names are proposed. Illustrations are provided for previously unillustrated species. Aspects of morphology, architecture, and infrageneric and suprageneric relationships are briefly discussed.
