Ushadi, For molecular studies the herbarium specimens are not eligible as these are poisoned. Sometimes back someone requested me to send fresh leaf samples of Nicobariodendron sleumeri, tentatively placed under Celastraceae, for molecular studies to solve the problem whether it really belongs to the Celastraceae or a new family should be proposed. Thus if Nicolas ji can find out some way of preserving his materials without poisoning, it is quite good but at the same time he should adhere to the valuable suggestions given by Pankaj ji. Regards, Tapas.
