The barren form, the only one which has been found in Denmark, must be reckoned to the P. ampHfolius-gvoup, if we want to class it into the above given system; in the structure of the axial cylinder, however, it often approaches to the P. iKceHS-group which is simply because the barren form is certainly a bastard between P. lucens and P. nutans. If only we stick to the charac- ters here used, the barren form shows the following facts: In the bark of the stem are numerous bundles (Fig. 8), in part some rudimentary, with bast surrounded vascular bundles; in part and.
