The description and drawing in the Botanical register, from a Sumatra 

 specimen, agree perfectly well with our Java plant. The anther is here 

 recurved and the appendix very small, it varies in the Java plant from '/2-3 

 mm, and is recurved or reflexed, the cells of the anther are linear, parallel 

 only at their base, and much diverging from the middle upward. The 

 staminodes are widely obovate, shorter and broader than the petals, and of 

 a bright pink colour as well as the petals. In the figures of Roscoe the 

 appendix is almost as long as the cells, and the staminodes are narrowly 

 oblong and white. Here is either represented a different species or the dra- 

 wing is very incorrect. But Trimen, 1898, 243. also described the staminodes 

 as oval-oblong. Probably, therefore, there exist two different forms.
