Summary

Envelope containing specimens (apparently mentioned in the letter from Daniel Oliver 27 February 1863 (S 4015)).

Summary

Compliments DO on his wealth of information.

Henrietta’s relapse.

Thanks for extract on Drosera.

Summary

Ferdinand Cohn has already sent a copy of his article, [possibly: "Über die Function der Blasen von Aldrovanda und Utricularia", Beitr. Biol. Pflanz. 1 (1870–5) pt 3: 71–89].

Summary

Delighted to try experiments on Drosera spathulata.

Summary

CD never dreamed primroses did not abound with DO; apologises for trouble and sends flowers.

Will repay DO for cost of Cypripedium and for the Dionaea, if any can be got.

Summary

Congratulations on DO’s marriage.

Summary

Finds no trace of nectar in Stanhopea saccata.

Summary

Gives a reference to a paper.

Summary

Thanks for correcting Fritz Miller’s paper on climbing plants. CD will send it to Linnean Society.

Summary

Thanks for the information about the action of roots on rocks.

Summary

Sends capsules with results from Genlisea specimens and fragments of Polypompholyx.

Summary

Thanks for Forms of flowers.

Alexander Dickson would like to know whether anyone has described the epidermal cells lining the pitcher of Cephalotus.

Summary

Wants to amend request [see 2946] if DO wants to try carbonate of ammonia experiment. Put third drop on midrib of leaf [of Dionaea] or inside upper side.

Sorry DO already has Origin. Would he like Journal of Travels [Journal of researches]?

Summary

Requests Oxalis acetosella, which he suspects is dimorphic.

Summary

Distinguishes two kinds of floral dimorphism: that affecting sexual organs and that affecting outer envelopes.

Summary

Thanks for Oxalis. Only experimentation will show whether disproportion of long- to short-styled flowers is a functional dimorphism.

Case of aestival flowers is very curious.

Summary

Thanks for information on Primula ovules. From what DO says the pollen-tubes ought to find their way to the micropyle.

Summary

Recommends Wyman’s short notice ["Report on Dr Jeffries Wyman’s experiment on the cause of contractility in vegetable tissues"] in the Proceedings of the American Academy of Arts and Sciences 3 (1852–7): 167.
