 very variable, and this seems to have given rise to a number of 

 synonyms. In the form pontederiaefolia the leaves are deltoid and 

 usually less cordate, and sometimes even quite entire with a very broad 

 base. In a drawing of a Perak specimen collected by Scortechini 

 the base of the spathe is figured as swollen, which occasionally occurs. 

 Distribution Malay Islands.
