1. The leaves of following eight species belonging to Sect. Graciles are treated from the anatomical view point in this paper:
Carex Nakiri, C. sendaica, C. brunnea, C. sacrosancta, C. Hattoriana,
C. autumnalis, C. subteiogyna and C. scabriculmis.
2. All these species resemble one another very much, and have common peculiar characteristics. Hinge cells form a central band and two lateral bands: cells of the central band are generally similar in their structures to the upper epidermal cells on the mesophyll or on the nerve, cells of the lateral band generally have thick and slightly wavy or smooth walls, like the hinge cells of many other Carices; larger and smaller vascular bundles generally alternate, and fibre cells stretch widely directly on inner sides of the upper epidermis as larger ones and below the under epidermis as smaller ones, and the fibre cells neighbouring the margin stretch conspicuously widely beneath the upper epidermis. Spine cells are found in all parts of the upper epidermis excepting the lateral bands of the hinge cells, and the margins, though sparsely on the nerves of the under epidermis.
