Nippon, in fossis circa Yoko- hamam semel inveni ; * IV.—The Stem. The stems vary in length from a few inches to upwards of two feet, and they have many branches. Considering the large number of leaves which they support, the stems are comparatively weak; they do not vary much in diameter from the base to the summit; vertical sections of the upper internodes are not quite so circular as those of the lower Fig. 42. If we examine one of these internodes we find that the centre of the shaft consists of a small channel, surrounded by two or three layers of elongate cells somewhat closely aggregated; surrounding , these is a much larger cells, hexagonal in outline, and having thinner walls than those which protect the central channel. From this central mass radiates a series of from eight to twelve prolongations of the central hexagonal cells, meeting as many out- growths from the tissue which forms the circumference of the internode, and arranged like the spokes of a wheel.
