In his paper: "Recherches sur la naissance des feuilles et sur l'origine foliaire de la tige (Revue gén. de Bot., 19, 1907), . Fig. 1. Fagus silvatica: Transverse Fig.2. Alnus glutinosa: Transverse section of a part of the central section of a part of the central cylinder; young vascular bundle; cylinder; young vascular bundle; X c. 450. X c. 550. L. Flot gives a very instructive figure of the young stem of a Betula. Here is shown not a solid cylinder, but distinctly separate bundles. Also in Fraxinus excelsior, Sorbus aucuparia and Euonymus latifolia (Fig. 3) I have found young bundles. Amongst herba- ceous plants and shrubs I have examined Linum austriacum (Fig. 4), Potentilla palustris, Rubus Idseus (Fig. 5) and Rubus sp., Hype- ricum quadrangulum (Fig. 6) and some Veronica species. Of these species, of which Linum, Hypericum, Potentilla, and Veronica possess an early developed continuous cylinder, I have proved the existence of isolated bundles besides distinct leaf-trace bundles. In Hypericum, Potentilla palustris as well as in Veronica, it is.
