Arranges for HdeV to call.
Regrets he cannot receive HdeV at Down, because he has just left home.
Enjoyed seeing HdeV yesterday.
Following the point mentioned by HdeV, CD has observed the difference in corrugation of primary roots in plants exposed to dry and damp soil.
Discusses heliotropism in plant cotyledons. Asks for information.
Thanks for letter.
Comments on growth and movement of plants.
Perhaps movement from side to side in plants is caused by the contraction of one side, rather than the expansion of the other.
Sends seeds of Lychnis Githago: he observed the hypocotyledenous stem, not the root, contracting.
Thanks for copies of HdV’s two articles on climbing plants (Vries 1873a and 1873b).
