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

Abstract

1. Remarks on the anatomical characteristics of the leaves of three Carices described in this paper are as follows:
Carex Middendorffii FR. SCHMIDT: Hinge cells in two layers and having wavy walls. Spine cells existing in the upper epidermis on the nerves, the under epidermis and the margins. Protuberances occurring densely in the under epidermis. Subsidiary cells of the stomata protruding in their both ends. Transfusion cells conspicuous.
Carex Lyngbyei HORNEM.: Hinge cells in two layers and having thick walls. Protuberances numerous in the under epidermis. Subsidiary cells of the stomata protruding in their both ends. Transfusion cells conspicuous.
Carex ketonensis AKIY.: Very similar to Carex Lyngbyei, but differing in having robust spine cells in the upper epidermal cells on the nerves and the margins.
2. In seven papers (XIII, XIV, XX, XXVIII, XXIX, XXXI and XXXII), the author treated twenty species belonging to the Sect. Acutae. The characteristics common to these species are as follows:
i. Subsidiary cells of the stomata protruding in some degree (except. C. kiotensis and C. phaeopoda).
ii. Protuberances occurring numerously on the epidermal cells in the stomata bands (except. C. aequialta, C. kiotensis and C. phaeopoda).
iii. Stomata small and rounded.
iv. Transfusion cells conspicuous etc.
