%X The formation of lenticels on the branches of Ficus microcarpa L. F. was examined. Beneath the stomata of a young branch, the division of precomplementary cells progressed from the cortex inwards and then the lenticel phellogen was formed. It was found to be continuous with the phellogen of periderm. The phellogen of the lenticel centrifugally produced a compact suberized closing layer and then one to four layers of unsuberized complementary cells. The mature lenticels are lens-shaped and convex towards both the exterior and interior. They are centrifugally composed of phylloderm, lenticel phellogen, and several strata of complementary cell layers alternated with a single closing layer. In the lenticel,  some prismatic calcium oxalate crystals and several rows of radially arranged tannin cells were observed. Lenticel hypertrophy arose in the immersed mature internodes. It was characterized by large and loosely interconnected thin-walled cells.
