Darwin-Hooker Letters : Letter from Hooker, J. D. to Darwin, C. R. on 11 June 1864 : 225r
'Hooker, J. D.'
Darwin's photograph looks like J. R. Herbert's Moses in the fresco in the House of Lords. Hooker is delighted about oxlip, but hybridity does not explain some large patches that are uniform and do not vary towards either cowslip or primrose. Encloses letter from W. H. Harvey discussing Myosotis sylvatica and the common dandelion.
