II. 95 ... directed issue from this axis in the same wa\ as in the preceding species. These axes run through the middle of the short lateral branches before mentioned, and accordingly they attain only a rather small length. Fibres issue from the axes of the stem and the branches, quite corresponding to the fibres of the branchlets in the preceding species. They issue all round, and most frequently they are- arranged in a more or less circular way, and they are inserted in the axes in the common manner, so that in a transverse section they are seen to meet in the middle (Woodcut fig. 5). The circular arrange- ment cannot be seen in the exterior, but when the layer of tissue is separated from the axes, a linglike structure is seen in these, owing to the basal parts of the small axes, which are inserted into the axis (PI. Ill, fig. S). Xow the only difference between this species and the preceding ones is that while in these the fibres inserted in the axes support free branchlets, they support in the present species the coherent part of tissue on the steins and branches, continuing from the axis out through this tissue, and their ends projecting a little. These fibres are in this species of about the same thickness through- out their length; sometimes they are a little curved. They may be somewhat branched, especially in their outer part, so that the number of projecting ends is greater than the number of fibres inserted in the axis. The part of the sponge coating the stem and the lateral branches and supported by the mentioned small fibres is not solid, but is, as before mentioned, pierced by a coherent system of cavities. A row of cavities is especially found inmost, round the axis, arranged like stories above each other, separated by the almost plate-shaped parts of tissue in which the small fibres run, but st
