    • Abstract


      Two lichens are found on the sandal trees of Coorg which do not suffer adverse effects on this account.Parmelia tinctorum was earlier reported to contain atranorin and lecanoric acid; considerable amounts of nor-stictic acid are now isolated from it.Usnea japonica is reported for the first time in India. Besides usnic and stictic acids already known in this source, barbatolic acid also has now been found to be present in it.
