Sir, I would further like to add that *Amaranthus gangeticus* L. of the "Bengal Plants" includes following species of Flora Indica ;-
- *A. gangeticus* - *A. oleraceus* - *A. lanceolatus* - *A. atropurpureus* - *A. tricolor* - *A. melancholicus* - *A. lividus* "Bengal Plants" also describes - - "The species separated by Roxburgh are well-marked races of this variety, and some of them, but more particularly the race described in the Flora Indica as *A. oleraceus*, possess many more or less distinguishable and definite subraces or cultivated forms. About *A. gangeticus* var. *tristis*, the "Bengal Plants" describes - - "as variable in shape and coloration of leaves as the preceding variety (*A. gangeticus*), ......... but particularly the race named *A. tristis*, include a multitude of distinguishable subraces and cultivated forms......"
