Your observations were correct. I worked on Indian Acacias long back and published an account of the same in 1996. As regards Acacia caesia, it is indeed a variable species and I merged A. torta with it, having found ample intergradations. I had examined relevant specimens in all the major Indian herbaria. It is interesting to note that while majority of the collectors mentioned it to be scandent shrubs or climbers, many others found it to be trees, 3 - 10 m high. In recent past the indigenous Indian species of Acacia were transferred mainly to Senegalia and Vachellia. I noticed some discrepancies in these publications but I have not published any rejoinder on them except for one short note on Vachellia eburnea as this is not my priority area at present. I am not at all fully satisfied with these publications. I came to know that a Ph. D. student at Goa University is now working on Indian Acacias and he has found some ways for differentiating A. caesia from A. torta. There is, however, no publication seen by me from that end. I can raise several questions which are to be answered by the future workers on Indian Acacias. Regards, Tapas.
