Thanks a lot for the details. At University of Calicut there should eb athesis by Dr. Jana Sckornikova on the revision of Indian Curcumas. It can help further. I remember when I was doing field work with Jana (she for Curcuma and me for orchids) for some time she use to lick the leaves always to check the hairs first :))
