Anatomical characteristics of the leaves of
Carex aequialta,
C. aphyllopus and
C. caespitosa are described in this paper; the remarkable points of the characteristics are as below:
Carex aequialta KÜKENTHAL: Upper epidermal cells and the cells in the margins are large and thick-walled. Stomata are small and have protruded subsidiary cells. Transfusion cells are conspicuous. Protuberanceshardly occur in the epidermis.
Carex aphyllopus KÜKENTHAL: Spine cells are found in the upper epidermis on the large nerves, margins and the under epidermis on the midrib. Protuberances occur in the upper epidermis sparsely, and almost all the cells in the under epidermis. Hinge cells have thin and wavy cell walls. Somata are small and have protruded subsidiary cells.
Carex caespitosa L.: Hinge cells are in many rows and in two or more layers. All epidermal cells, excepting in the margins, are thin-walled. Protuberances occur mostly in the under epidermis. All vascular bundles are of almost equal size. Transfusion cells are conspicuous.
