The description is taken from dried and living plants. A non-flowering 

 plant, cultivated in the Buitenzorg Gardens, which seems to be a more 

 strongly developed spécimen of this, differs in having the dimensions of 

 the leaves twice to thrice as large, with the lamina elliptical-oblong, broadest 

 at the middle, and the base abruptly rotundate-truncate, hardly cordate- 

 emarginate. The crests of the pétiole are partly deciduous, leaving the 

 pétiole slightly, longitudinally ribbed when they fall.
