This genus differs from Kaempferia by its polygamous flowers, and from all 

 species of Kaempferia known to us, K. Ethelae only excepted, by the ovaries being 

 below the surface of the ground. A large number of the plants have been under 

 our observation during the flowering season, but very few hermaphrodite flowers 

 have been noted, the female flowers largely outnumbering them, and in no case, so 

 far as we have been able to find, have seeds been produced, the ovaries rotting in 

 the ground, though the flowers are visited by a minute " Mucid fly," the name of 

 which we have not been able to ascertain. The tube of the female flowers is very
