Summary

Thanks for "multitudinous" references.

Thanks Hooker for orchids.

Summary

Fertile flowers of violets, except Viola tricolor, require insect visits.

Summary

Sends Hermann Crüger’s paper ["A few notes on the fecundation of orchids and their morphology", J. Proc. Linn. Soc. Lond. (Bot.) 8 (1865): 127–35] for publication.

"Boasts" of confirmation that sexes are separate in Catasetum.

Summary

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.

Summary

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?

Summary

Thanks for DO’s Lessons in elementary botany [1864].

Asks him to inquire whether there are any twining species of Passiflora.

Summary

Asks DO to draw diagram of Lythrum on board at Linnean Society for reference during the reading of CD’s paper.

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

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

Summary

Will DO observe whether leaf [of Nepenthes] with pitcher ever wound round a stick? CD’s plant is improving.

Summary

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.

Summary

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

Summary

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].

Summary

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.

Summary

Is it now thought that the spongioles of rootlets secrete carbonic acid which acts on bones and rocks?

Summary

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

Summary

Thanks him for specimens.

Summary

Returns insectivorous plants to Kew, with questions about their range. Most species seem to have remarkably confined ranges.

Asks for a Bengal Aldrovanda leaf so that he can see whether it differs from the German species.

Roridula interested him extremely.

Summary

Asks four favours: sort out confusion about the name Byblis gigantea or grandiflora; can he see dried specimens of Genlisea ornata; is there a more recent list of Drosera spp. than Steudel 1841; are there at Kew any dried specimens of Utricularia montana collected from the plant’s native haunts.

Summary

Returning the plants DO had sent him from Kew
