Note 198 — Chapter V · Hook and Root-Climbers.—Concluding Remarks.

Such slight spontaneous movements, I now find, have been for some time known to occur, for instance with the flower-stems of Brassica napus and with the leaves of many plants: Sachs’ ‘Text-Book of Botany’ 1875, pp. 766, 785. Fritz Müller also has shown in relation to our present subject (‘Jenaischen Zeitschrift,’ Bd. V. Heft 2, p. 133) that the stems, whilst young, of an Alisma and of a Linum are continually performing slight movements to all points of the compass, like those of climbing plants.
