Cinnamomum camphora(L.) Presl(Lauraceae), a handsome evergreen tree. native of China, japan, and Formosa, has been introduced to India in the fifiies as an ornamental plant and also for commercial extraction of natural camphor. At present two chemically distinct populations of the taxon have been recognised,in N. E. India. One population is rich in campllor while in the other the major constituent is cineole (69.6 %) in the oil. although they are apparently indistinguishable morphologicaJly. The attempt to investigate the micromorphological variations, between them, however, revealed few interesting findings. The leaves of the camphora type bear no intersecondary vein and presence of variations in veinlet entering and veinlet termination number per islet.Intersecondary composite in cineola type and no variations are recorded in veinlet entering and veinlet termination number in the islets . Moreover, anomocytic stomata is present in camphora type found to be absent in cineola type . Sunken stomata with poor content of subsidiary cells are rare in the former but these are frequent with subsidiary cells rich in content in the later type. Unlike cineola type, the stomatal pores of Camphora type become obliterate due to the presence certain rod shaped structures. In addition to the characters, nonglandular foliar trichomes give separate identity to cineola type . These micro-morphological characters have immense significance for easy recognition of the two populations even an intermixed conditions.
