1. Remarks on the anatomical characteristics of the three species of Carices described in this paper are shown as below.
Carex Rochebruni FRANCH, et SAV.: Upper epidermal cells are large. Protuberances occur in the upper epidermis near the margins. Upper epidermal cells on the nerve are quite similar to those on the mesophyll.
Carex stipata MUEHL.: All epidermal cells are large and have conspicuously wavy cell-walls. Protuberances are found in the upper epidermis on the nerve. Spine cells and protuberances are densely distributed in the margins.
Carex tenuiflora WAHL.: Protuberances are widely distributed in the upper epidermis on the nerve, in all the cells of the under epidermis and in the margins. Subsidiary cells of the stomata are narrow.
2. Nineteen species hitherto described in five papers published presiously to this, and eight species belonging to Canescentes and Macroce- phalae formerly described, belong to the Subgenus Vignea. Those have not the common critical characters in the leaf-structures to authorize their being grouped as a subgenus, and this fact seems to the writer to suggest that the subgenera of the Carices formerly established should be more fully examined.
