A very handsome plant, allied to Impatiens arguta of India and its 
near ally Impatiens pseudarguta of China, but differing greatly in the 
Size and membranous texture of the erenulate leaves, and in the much 
larger flowers and capsules. Unfortunately the specimens are in a 
Very bad state of preservation as regards the flowers, which I found 
it impossible to analyse satisfactorily; these are described as of a violet 
colour,
