Hedera helix L. is commonly grown in our area as an indoor ornamental plant and in milder climates it thrives outdoors. Its capacity to endure difficult conditions is well known and quite naturally it has been used extensively in teaching and research. Several studies have related to its leaf form and size under various conditions. Ursprung and Blum explored its osmotic values and their work was later summarized by Ursprung (1929). Watson's recent papers (1942 a., 1942 b) discussed certain, aspects of its leaf tissues. The present paper deals with general foliar organizati9n of this plant in comparison with mesomorphic leaves.
