    • 1880, Charles Darwin, The power of movement in plants (London: John Murray, p. 450-451) online:
      But some tendrils are apheliotropic, for instance those of Bignonia capreolata and of Smilax aspera; and the stems of some plants which climb by rootlets, as those of the Ivy and Tecoma radicans, are likewise apheliotropic, and they thus find a support.
