Dear Sid, Thanks a lot for the clarification. I can make out that you have a good hold on understanding the studies on Molecular systematics. I would really be interested in knowing about your whereabouts to learn more from you as I dont know much abt this field and hence I would be interested in getting in touch with u. My email id is [email protected]. At the same time I really like Tanay's comments on, "If Heterostemon from upper Amazon has similarity then there should me some evidences in middle and lower Amazon in form of fossils for T indica, or any kind of transitional plant". My confusion was based on Heterostemon's origin in amazon...but lets see as said by him this theory is speculative and not affirmative and as said by you that it is possible. Lets say, may be due to inadequate sampling we cant reach to conclusion. Thanks again for putting up so much of info on a simple Tamarind!!!! This shows we still need to study hard each and every plant in our locality to understand every aspect of it.
Nice....keep it up.... Regards Pankaj
