The description above is taken from Wall. Cat. 2373a, -which is Nees' "type" 

 of Hygrophila salicifoUa. The Selangor example diii'ers from this in having the 

 capsules -8 in. long, in which point it resembles U. quadrivalvis, Nees, below. 

 T. Anderson esteemed the whole of the species in the present section to constitute 

 but one polymorphic species (.Journ. Linn. Soc. IX. 456 (1867) ). They are described 

 here shortly only, with reference to their differences from H. salicifoUa, Nees, taken 

 as the standard form.

 333 (1893). SmaU, rigid, branched, 6 to 14 in. high. Leaves approxi-
