The Zamioculcas and Gonatopus
Online Library

(…)

Several genera have been described after Engler's monograph (1905 - 1920), but most of them are synonyms of already known genera. A few genera accepted by Engler are reduced now and these are listed below too, as well as a few not cited by him. For other synonyms see Engler's monograph (1905 - 1920).

On the left side the synonymous generic name is given and on the right side the generic name under which it is accepted today.
