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

Abstract

The leaves of Carex Thunbergii STEUD., C. subspathacea WORMSK. and C. rikuchiuensis AKIYAMA, belonging to the Sect. Acutae, are treated anatomically in this paper. All these species have the stomata widely and densely distributed in the upper epidermis, and rather scarcely in the under epidermis, in this point the species may be grouped together.
In C. Thunbergii the stomata and the protuberances are scarce in the under epidermis, and rather numerous in C. rikuchiuensis. Transfusion cells are not evident in C. Thunbergii and conspicuous in other two species. Spine cells in the upper epidermis are found only in C. rikuchiuensis.
