Note 165 — Chapter IV · Tendril-Bearers—(continued).

See M. Isid. Léon in Bull. Soc. Bot. de France, tom. v. 1858, p. 650. Dr. H. de Vries points out (p. 306) that I have overlooked, in the first edition of this essay, the following sentence by Mohl: “After a tendril has caught a support, it begins in some days to wind into a spire, which, since the tendril is made fast at both extremities, must of necessity be in some places to the right, in others to the left.” But I am not surprised that this brief sentence, without any further explanation did not attract my attention.
