The Charles Darwin Collection
The Darwin Correspondence Project is publishing letters written by and to the naturalist Charles Darwin (1809–1882). Complete transcripts of letters are being made available through the Project’s website (www.darwinproject.ac.uk) after publication in the ongoing print edition of The Correspondence of Charles Darwin (Cambridge University Press 1985–). Metadata and summaries of all known letters (c. 15,000) appear in Ɛpsilon, and the full texts of available letters can also be searched, with links to the full texts.
Struck with corresponding positions of tendrils and flower-stalks in Passiflora. Sends [W. E. Darwin’s] dissection drawings of earliest stages. Infers that tendril is a modified flower peduncle.
Requests DO look at mode of climbing in Tecoma.
Thanks for information on Tecoma.
Cannot believe DO’s statement about Catasetum; is sure C. tridentatum sets seeds in its native country.
CD erred on Acropera, but how is it naturally fertilised?
Thanks for DO’s Lessons in elementary botany [1864].
Asks him to inquire whether there are any twining species of Passiflora.
Asks DO to draw diagram of Lythrum on board at Linnean Society for reference during the reading of CD’s paper.
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)].
If CD understood Nepenthes, he would understand every class of climbers.
Will DO observe whether leaf [of Nepenthes] with pitcher ever wound round a stick? CD’s plant is improving.
Glad that Oliver is to review John Scott’s paper in the Natural History Review (Scott 1864a). Apologises that his enclosed references (now missing) are so paltry.
Thanks for correcting Fritz Miller’s paper on climbing plants. CD will send it to Linnean Society.
Requests addresses of J. E. Planchon, W. F. Hofmeister and M. J. Schleiden so he can send them copies of Lythrum paper [Collected papers 2: 106–31].
Sends Fritz Müller’s paper ["Notes on some of the climbing plants near Desterro, in S. Brazil", J. Proc. Linn. Soc. Lond. (Bot.) 9 (1867): 344–9] to be refereed.
Extracts from botanical literature dealing with Dionaea, intercrossing, and sensitivity. [Bot. Ztg. (1833): 96; Thomas Nuttall, Genera of N. American plants (1818)].
Cites descriptions of melastomads in C. V. Naudin, Annales des Sciences Naturelles 3d ser., vols. 12–18.
CD’s observations on preference of Drosera for milk and nitrogenous fluids, and the effect of nitrate of ammonia are interesting. Asks whether CD is satisfied that the effect is not due to density of fluid or to a chemical irritant. His own observations suggest such possibilities.
His results with pure gum on Drosera spathulata entirely support CD’s opinion. Other observations on insectivorous plants.
Quotes note by Julius Milde on Drosera rotundifolia from Botanische Zeitung (1852): 540.
Dr Hooker has given him CD’s memorandum on the fly-catcher.
Copies out extract from Curtis’ Botanical Magazine [On Apocynum androsæmifolium, 8 (1794): tab.]: 280 and gives a further reference in Erasmus Darwin’s The loves of plants [1789]. Suggests that they look at Apocynum.
List of references on orchid structure and fertilisation.
Finds no trace of nectar in Stanhopea saccata.
Refers CD to a paper which he ought to know: Ch. Fermond, "Faits pour servir à l’histoire générale de la fécondation chez les végétaux", Recueil des travaux de la Société d’émulation pour les sciences pharmaceutiques 3 (1859).
