My dear Dyer

I thank you for a heap of things. The Arachis arrived in admirable condition, & I have been observing it ever since. I have no doubt the pointed gynophores c^d. penetrate the ground without any aid; but they seem to be always in movement: I c^d not resist dissecting one & what a curious structure it is!² I also received a fine Pinus which has likewise been under observation: I have written to M^essrs Barron to know what I am indebted to them.³ Pray thank M^r Smith for trouble he has kindly taken about the Pinus.—⁴

I had forgotten about Tropæolum & will raise some plants. Many thanks for Oxalis seeds; they are treasures to me.—⁵

Please tell Sir Joseph that I am particularly obliged for name of Trifolium, which by accident was sent me from Kew as T. resupinatum: it has removed a load off my mind, for I thought I must have been mad last year, the two Trifoliums behaved so differently.— If at end of month or later in autumn I could any how get seeds of true T. resupinatum, they w^d be of great value to us, for Sachs has been suggesting a notion about bloom to Frank, which the leaves of T. resupinatum & of no other plant in world would perhaps solve.—⁶ This is my sole request at present.

Yours very truly | Ch. Darwin

I remember the roots, which you showed me at Kew, but forget whether they were positively or negatively heliotropic & what kind of plant it was.—⁷
