Note 176 — Chapter IV · Tendril-Bearers—(continued).
Reading edition

Translation, 1875, p. 280), has shown that which I overlooked, namely, that the tendrils of different species are adapted to clasp supports of different thicknesses. He further shows that after a tendril has clasped a support it subsequently tightens its hold.
