On the Systematic Anatomy of the Leaves of Some Japanese Carices. XXXI

Abstract

In the present paper, the author deals anatomically with the leaves of four Carices; the remarkable points of the characteristics are as below:-
Carex Maximowiczii MIQUEL: Upper epidermal cells large. Spine cells existing in the upper epidermis on the nerve. Under epidermal cells thin-walled. Spherical protuberances occurring densely in the under epidermis. Subsidiary cells protruding in their middle parts.
Carex incisa BOOTT: Spine cells occurring in the upper epidermis and the margins. Protuberances existing on almost all the cells in the under epidermis. Stomata rounded; subsidiary cells protruding upwards and completely covering the gurd cells.
Carex descendens KÜKENTHAL: Upper epidermal cells comparatively small. Hinge cells in two layers. Spine cells existing both in the upper and under epidermis on the nerves. Subsidiary cells protruding and completely covering the gurd cells.
Carex dimorpholepis STEUDEL: Hinge cells having wavy walls. Large spine cells found in the margins, in the upper epidermis on the nerves and in the under epidermis on the midrib. Small protuberances occurring rather scarcely in the under epidermis. Subsidiary cells of the stomata slightly protruding.
