( 1 ) The writer studied on the developmental process of the oilgland and the secretory duct and thc santonin quantity in Artemisia Kurramensis QAZILBASH. ( 2 ) The oilgland takes its rise in one epldermis cell. This epidermis cell divides into the oilglancl mother cell and as a result of five divisions four stalk cells and eight oilgland cells are completed and the chloroplastid is contained in these cells. These oilglands grow well on the epidermis of stalks, leaves and buds. ( 3 ) As the oilgland grows, reslnous substances are accumulated in the oil sac. On the other hand santonin substances are accumulated In the lowest oilgland cells, and after their quantity increases in there, they are accumulated in the upper oilgland cells gradually, and at last they have been accumulated in the oll sac with resinous substances. ( 4 ) Secretory duct grows along the bundles in the inter tissues of the stem, leaf and bud and it is cornposed of many flat and slender secretory cells and the schizogcnous intercellular space occuring between these secretory cells. On early stage much resinous substances are contained in this secretor duct but after that santonin substances are accumulatecl in it with resinous substances.
