An Abnormal Stem of Lonicera Periclymenum. 237 
Node 6 (leaf 8). No commissure was present between leaves 
seven and eight, but the eighth leaf formed the first of a series 
extending to the apex of the stem, arising singly at each node, and 
joined by a commissural ridge. As regards internal structure, the 
sixth node was identical with the previous one. 
Node 7 (leaf 9). All leaves from the ninth onward were on the 
same side of the stem (Figs. II and III). 
Fig. III. Part of Abnormal Stem of Lonicera Periclymenum. The figures 
refer to the number of the leaves beginning at the bottom of the stem.
