Perak, Kinta Valley, Lahat (Ridley). 



In ponds, and ditches, abundant but local. Native name " Bak- 

 ung." Distrib; Ceylon : Java, Sumatra. 



A very distinct plant from the other species when alive, and im- 

 possible to confuse with it. It is strictly aquatic (whereas the other 

 species inhabits dense forest only), and forms great floating masses in 

 the Siak River, Sumatra, almost blocking it. Though described as 

 having pubescence on the base of the leaves, and (Fl. Brit. Ind.) also 

 on the panicle, I have seen no trace of any pubescence on it any- 

 where.

 dark green, lighter and slightly cobwebby beneath, lamina lanceolate 

 acuminate 12-50 inches long 2-4 inches wide petiole channelled 3 or 4 

 inches to a foot long. Panicles 1-2 feet long lax, branches in half 

 whorls 2-G inches long tomentose with leafy bracts at the bases of the 

 lower whorls, peduncle and branches cobwebby. Flowers sessile scat- 

 tered. Male panicles with very slender branches. Male flowers of 2 

 or 3 small orbicular sepals. Petals oblong lanceolate. Stamens 5 or 

 6, bases linear above filiform. Pistillode small 5 or G lobed. Female
