City on the Ganges (5)
I believe the answer is:
patna
'city on the ganges' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for patna that I've seen before include "Variety of long-grain rice" , "Long-grain rice type" , "City of savoury rice" , "Long-grained rice type" , "Source of long-grain rice" .)
