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

Abstract

Anatomical characteristics on the leaves of four Carices are described in this paper, the remarkable points of each species are as follows.
Carex accrescens OHWI: Spine cells are widely distributed in the uper epidermis, the margins and the under epidermis on the nerve. Protuberances occur sparsely in the upper epidermis on the nerve.
Carex albata BOOTT: Hinge cells differ clearly from the epidermis on the mesophyll. Upper epidermal cells on the nerve are indistinct. Stomata spread sparcely.
Carex arenicola FR. SCHMIDT: Upper epidermal cells on the mesophyll are narrow. Walls of the hinge cells are thick and rarely wavy.
Carex cyperoides MURR.: All epidermal cells are long and wide. Protuberances are scattered in the upper epidermis on the nerve and the margins. Spine cells are found in the under epidermis on the midrib.
