To Hugo de Vries   10 November 1875

Down, | Beckenham, Kent.

Nov 10. 75

Dear Sir

Your very kind letter has pleased me greatly.1 I write now to suggest, if you make any more observations on tendrils, to attend to the very curious case described at p 132 of my book under Echinocystis,—namely that the extremity of a tendril which has curled half round a small cylindrical stick, can by an undulatory movement, curl twice or thrice round the stick. This seems to me a point worthy of further investigation, and if my measurements can be trusted shows that the movement is not due to growth along the convex surface.2

With much respect | I remain | Dear Sir | Yours faithfully | Charles Darwin


See letter from Hugo de Vries, 7 November 1875 and n. 6. CD’s observations on Echinocystis lobata (wild cucumber) are in Climbing plants 2d ed., pp. 128–34.

Suggests that, if HdV make further observations on tendrils, he attend to Echinocystis, as described on p. 132 of Climbing plants.
