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?

Asks DO to give enclosed [letter?] from John Scott to Hooker.

JS’s work on orchid self-sterility; Acropera has 371250 seeds in one capsule.

Wishes something could be done for Scott.

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.

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.

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

Asks DO to identify a plant grown from earth adhering to the foot of a woodcock.

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

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

Thanks him for specimens.

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.

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.

Returning the plants DO had sent him from Kew

CD’s observations [for Insectivorous plants] seem to indicate that the same species of Genlisea may bear two kinds of bladders, so he asks for rhizomes and leaves of three species to test this possibility.

Asks DO to return enclosed post-card with locality of Genlisea aurea specimen that DO had sent.
