This description is taken principally from one single specimen, cul- 

 tivated by Mr. Heyne out of a rhizome purchased at the bazar in 

 Batavia. The rhizome is distinguished by experts and herbmongers from 

 Z. amaricans by the more fleshy consistence and apparently by some pecu- 

 liarity of smell. 



The spike resembles much that of Z. amaricans. It is however shorter 

 and less pointed and the flowers are very different and more like those of 

 Z. zerumbet by the shape of lip and staminodes (see Pi. xv fig. 9 and 10); 

 but different by the smallness and orange coloring. 



As a wild form of this species I consider the specimens collected in 

 the teakforest of Randublatung and Kediri by Mr. Ralshoven, and those 

 collected in Madura by Mr. Backer. In both specimens the flower is orange 

 coloured, and the lip as wide as long and not clawed, by which characters 

 they are easily distinguished from Z. amaricans. But they differ as well 

 from the type of Z. aromaticum by the orbicular lip and narrow (elliptic) 

 staminodes and approach to Z. amaricans. Taking the orange-colour of the 

 flower and the shape of the lip as diagnostics of Z. aromaticum 1 distin- 

 guish' the following varieties.
