Having trouble understanding laws of phyllotaxy in order to grasp Hugh Falconer's objections.
L. C. Treviranus on Primula [see 3980] misses the "prettiness" of the adaptations.
John Scott says P. scotica is never dimorphic.

Many thanks about Phyllotaxy. Your cases seem sufficient & when next in London,
I shall hear what Falconer has to say. Do not look for any
more cases; but if you sh

Treviranus in his Review of the Orchids does not seem to appreciate at all the prettiness of the adaptations, which seems to me the cream of the case.

- f4 4052.f4In his review of `Dimorphic condition in Primula' (Treviranus 1863a, p. 4), Ludolph Christian Treviranus stated that Primula longiflora was homostyled. Treviranus had arranged for his review to be sent to CD earlier in the month (see letter from L. C. Treviranus, 12 February 1863). CD's annotated copy of Treviranus 1863a is in the Darwin Pamphlet Collection--CUL; at the head of the fourth page, CD noted that according to Treviranus P. longiflora was found `alone' and was `nondimorphic' and `shortstyled'.
- f5 4052.f5John Scott sent CD three specimens each of P. scotica and P. farinosa on 6 January 1863 (see letter from John Scott, 6 January 1863). See also letter from John Scott, 17 December  (Correspondence vol. 10). CD communicated Scott's observations on P. scotica to the Linnean Society on 4 February 1864 (Scott 1864a, p. 82).

Bentham worked with Oliver at the Royal Botanic Gardens, Kew.
