Summary

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

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

Gives a reference to a paper.

Summary

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

Summary

Has been copying out references from Natural History Review [possibly D. Oliver, "The structure of the stem in dicotyledons; being references to the literature of the subject", Nat. Hist. Rev. n.s. 2 (1862): 298–329].

Suggests DO study high incidence of separate sexes in freshwater plants.

Summary

Sends addresses of Planchon, Hofmeister, and Schleiden.

Hermann Crüger left no widow.

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

Finds no trace of nectar in Stanhopea saccata.

Summary

If CD understood Nepenthes, he would understand every class of climbers.

Summary

Requests DO apply carbonate of ammonia to sensitive hair of Dionaea and measure reaction time. Wants to compare Drosera and Dionaea.

Summary

Cares more for dimorphism now than for orchids. Today saw the three forms of Lythrum, which means there should be 18 different practicable crosses.

Summary

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

Summary

L. H. Palm [Über das Winden der Pflanzen (1827)] is better on climbing plants than H. von Mohl [Über den Bau und das Winden der Ranken und Schlingpflanzen (1827)].

Summary

The best way to see cell movement in Drosera hair, is to cut off those lately inflected over a fly, sketch shape of red matter under high power, and repeat after one or two minutes.

Summary

Discusses the female parts of the Primula flower; the true character of the free placenta is not completely understood.

Summary

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

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.

Summary

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

Summary

Discusses primrose ovules,

Atlantis paper [Nat. Hist. Rev. (1862): 149–70],

plant migrations;

Corydalis.
