    Four Carices are treated in this paper, remarkable characters are as below:
    Carex omiana FRANCH. et SAV.: Hinge cells resemble the upper epidermal cells on the mesophyll. Upper epidermal cells on the nerve are indistinct in spite of the conspicuousness of those in the under epidermis.
    Carex planata FR. et SAV.: Cells on the nerve in the upper epidermis are indistinct. Vascular bundles are small. Spine cells and protuberances are found only in the margins.
    Carex pseudo-loliacea FR. SCHMIDT: All epidermal cells have spherical protuberances. Hinge cells are low. Spine cells are small and found only in the margins. Transfusion cells are rather numerous.
    Carex remotiuscla WAHLENBERG: Upper epidermal cells are large. Protuberances occur in the upper epidermis and the margins. Spine cells are distributed in the under epidermis on the midrib and in the margins. Vascular bundles are poorly developed.

    By serial microtome-sections of large numbers, the writer traced the course of vascular bundles of Zea Mays from the terminal part of a male inflorescence, downwards to the middle part of the stem.
    At the terminal of the axis, several large medullary bundles and about ten small peripheral ones ar found; the former descend downwards through at least six nodes of successive leaves, in a case examined by the writer, without any direct connction with the leaf traces, and may be regarded as cauline bundles.
    At the lower part of the inflorescence axis, large medullary bundles are represented by the cauline bundles and the branch traces which originate from the lateral shoots i.e. the peduncles and the axes of secondary inflorescence. When traced downwards into the stem, they gradually migrate towards the periphery of the stem, diminishing in size, the branch traces fusing with the leaf traces.
    The connecting mode of branch traces to mother axis is very simple at the uppermost part of the axis, and somewhat similar to the case of some dicotyledons, but it is more complicated in the lower part of the inflorescence, and has been described in detail.

    In der vorliegenden Arbeit werden die Chromosomen bei Trichosanthes multiloba MIQ. und bei anderen 9 Arten und 6 Varietäten von Cucurbitaceen untersucht.
    1. In der Metaphase der heterotypischen Teilung in P. M. Z. von Trichosantes multiloba MIQ. erkennt man 11 Gemini, eins davon das X-Y-Geminus ist. Die Chromosomenformel dieser Art lautet:
    _??_2n=20+X+Y.
    2. Die Chromosomenzahlen der anderen 9 Arten und 6 Varietäten von Cucurbitaceen lassen sich feststellen (siehe Tabelle 1 S. 507).
