P. scandens var. zollingerianus), P. horsefieldii, P. scandens var. javanica, P. scandens var. zeylanica, P. scandens var. sumatrana and P. scandens fm. angustior are reduced to P. scandens; Pothos balansae, P. cathcartii, P. chinensis var. lotienensis, and P. warburghii to P. chinensis; Pothos ellipticus, P. grandispathus and P. ridleyanus to P. kingii; Pothos penicilliger to P. lancifolius; and Pothos peninsularis, P. kunstleri and P. maingayi to P. curtisii. Brief discussions of geography, shoot architecture and life form are presented. Dichotomous and multi-access keys to species and a geographical species finder-list are provided. All species are illustrated.
