Summary

CD, commenting on a case of peloric flowering in Auricula, urges readers to send in their observations on whether flowers nearest the axis tend to differ from others on the plant. Such a law of variation would be worth discovering.

Summary

Trusts DO’s opinion on Acropera ovules.

Summary

Comments on the travels of JDH.

Genera plantarum a most worthy undertaking.

Criticisms of the Darwin–Hooker understanding of HCW’s views of convergence.

Orchid anatomy. Wind as agent of self-fertilisation in orchids.

Summary

Thanks for mentioning J. G. Kurr on nectaries [Untersuchungen über die Bedeutung der Nektarien in den Blumen (1833)]. Requests observations on flowers with curved pistils. Finds they curve toward nectary, thus lying in path of insect.

Summary

Lieut. F. W. Hutton’s original review [Geologist 4 (1861): 132–6, 183–8] understands that mutability cannot be directly proved.

CD met Bentham at Linnean Society and asked him to write up his views on mutability.

Praises his paper ["Contributions to an insect fauna of the Amazon valley", read before Linnean Society, 21 Nov 1861, Trans. Linn. Soc. Lond. 23 (1862) : 495–566] which solves "one of the most perplexing problems which could be given to solve".

Discusses the difficulties of writing and expresses disappointment at Wallace’s book [Travels on the Amazon (1861)].

Summary

JDH’s letter on grounds of generalisation in plant morphology.

Faunal distribution and the glacial period.

Orchid homologies.

Summary

Thanks Mr Beaton for his answer [to 3147].

Asks further questions on points raised in Beaton’s previous papers: whether crossing white and blue varieties of Anemone apennina produced many pale shades; whether the Mathiola incana and M. glabra which crossed freely were artificially or naturally crossed.

CD is delighted by Beaton’s assertion that "not a flower in a thousand is fertilised by its own immediate pollen".

Recounts his experiments with Leschenaultia formosa to show insect fertilisation.

Summary
