DO thinks an essay [Alexander Braun's "Rejuvenescence", Ray Society (1853)] is not worth reading with respect to some difficulty concerning phyllotaxy.

My dear Sir
Next to save you throwing away valuable time, the connection with the phyllotaxy
difficulty it is not worth y
Ever Yours Sincerely | D. Oliver
- f1 8770.f1The reference is to Henfrey trans. 1853. In the letter to J. D. Hooker, 13 January , CD mentioned that he had been attempting to read this English translation of Braun 1851, continuing: `literally I cannot read it'. Apparently, CD had sought Oliver's help in searching the book for information on phyllotaxy (see n. 3, below). An annotated copy of Henfrey trans. 1853 is preserved in the Darwin Library--CUL (see Marginalia 1: 366--7).
- f2 8770.f2Braun cited Bravais and Bravais 1838, Naumann 1845, Schleiden 1842, and Silfverstrahle 1839 (Henfrey trans. 1853, pp. 116--17).
- f3 8770.f3CD's interest in phyllotaxy was stimulated by Hugh Falconer's discussion of Origin in his article `On the American fossil elephant of the regions bordering the Gulf of Mexico', published in the Natural History Review in January 1863 (Falconer 1863a). See letter to J. D. Hooker, 13 January  and n. 22. CD may have discussed Falconer's statements with Oliver during his visit to the Royal Botanic Gardens, Kew, on 11 February 1863 (Emma Darwin's diary (DAR 242)). CD wanted to understand the force of Falconer's objections to natural selection (see letter to Daniel Oliver, 20 [February 1863]), and began his own research on phyllotaxy. CD prepared a rough draft of a paper on phyllotaxy on 9 June 1863, which is in DAR 51: A1--32, together with a series of undated diagrams; however, the work was never published.
