The volumes of tissues in leaves of two species ofTypha with different habitus were measured. It was found that air cavities occupy more than 50%, parenchyma about 20% and photosynthetic tissue about 10% of the total volume of the leaf. If the cavities are omitted, parenehyma amounts to approximately 50% and photosynthetic tissue to little more than 20% of the total volume of tissues. The relative volumes of tissues vary continuously from the base to the tip of the leaf. The differences between the two species studied were not large. Besides the relative volumes, the real ones of leaves and tissues were calculated.
