A regular column is to appear in the Proceedings of the Royal Horticultural Society on successful and failed interspecific crosses.
CD’s climbing plant experiments make it impossible to deny nerve force in plants.
Has discussed Frankland’s new glacial theory with Lyell.
Bishop Colenso’s trial.
Possibility of Scott’s coming to Kew as a curator.
Is sending his monograph ["A revision and arrangement of the North American species of Astragalus and Oxytropis", Proc. Am. Acad. Arts & Sci. 6 (1863): 188–236].
Death of Francis Boott.
U. S. is now determined to do away with slavery.
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.
Thinks the paper by H. Crüger should appear in the Journal of the Linnean Society.
Does not know Scott’s qualifications to be curator at Kew.
Frankland’s theory of glaciers is absurd.
Has JDH heard claim that plants in Northern and Southern Hemispheres turn in opposite directions?
Are there plant families with no twining and climbing plants?
Sends a Corydalis.
Hermann Crüger’s paper [see 4394] splendid, but he has made a mess of propagating Cinchona in Trinidad.
JDH’s opinion of Germans.
Asks for a Smilax to study movement.
Has not worked for six months due to illness.
Has been looking at climbing plants.
Hermann Crüger’s paper shows that CD was right about Catasetum pollination. Crüger’s account of pollination of Coryanthes "beats everything".
Has drawn all three forms of primroses CD sent "with same result". Has found no pink variety with middle style.
Encloses memorandum on tendrils. Nature of tendrils in Modecca.
Observations on climbing species of Tacoma. [Tecoma!?]
Has received EH’s Die Radiolarien. Drawings admirably executed. Had no idea such low animals could develop such beautiful structures.
Acknowledges cancelled bond and thanks CD for declining to accept interest. Suggests 4 Mar 1865 as date for payment of the bill CD holds.
Thanks for paper ["Über die Entwicklungstheorie Darwins", Amtl. Ber. Versamml. Dtsch. Naturforsch. Aerzte 38 (1863): 17–30]. Delighted EH confirms his views. Many in England afraid to express views openly.
Has left his position at Edinburgh Botanic Garden.
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.
Discusses homologies of plant organs.
The passion-flower tendril should be considered a modified branch rather than a modified flower. Considers the distinction between the peduncle and the leaf midrib.
List of four plants sent.
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?
