To W. T. Thiselton-Dyer   23 November [1880]


WTT-D’s suggestion about absorbent function of pegs in Abronia suggests origin of pegs in Welwitschia, which deeply interests CD. Previously could not see how pegs became large enough to be of mechanical use. Now thinks tissue between hypocotyl and radicle absorbs fluid, which would favour rise of peg to expose larger surface.

Rejects German contempt for investigating use of organs.

Asks WTT-D to observe how worms draw Robinia leaves into burrows.
