So where do we stand Sir? Roxburgh's *A. echinatus*(*m*) is dubius/uncofirmed, meaning Roxburgh may not be correct at all! Thereby Wight and Prain are also wrong!
TPL thinks *A. echinatus* Roxb. is synonymous with, that too with three stars, with *A. crispus* Thunb. You, based on inflorescence colour and Garg Sir, based on leaf, think the species submitted by Anurag Ji is *A. natans* (L.) Engl. & K. Krause. So be it..... thank you very much.
