Abstract:

Remusatia Schott and Gonatanthus Klotzsch are two closely related genera of Colocasieae-Steudnerinae in Araceae. Both genera characteristically produce branched or unbranched aerial bulbiliferous shoots. All species of them with same basic chromosome num-bers ( 2n= 28) are diploid or triploid. Remusatia is distinguished from the genus Gonatanthus only on its parietal rather than basal placentation. But, the placentiaion is usu-ally various in the same species ( Remusatia ornata, Gonatanthus yunnanensis) . In fact Gonatanthus is so similar to Remusatia that we have to make a combination of them as following.
