Good morning Didi The KEY in the linked pdf file doesn't feature *Curcuma amada*. Since I have seen both the *amada* and the *longa* I think there is no way to identify them without examining rhizome. The pdf follows the 'Bengal Plants' pattern. I agree that in most cases the ID can be established without digging, taking care of distribution, and other aerial features. Even then you may need to dissect a number of flowers.
Thank you very much.
