The Fertilisation of Orchids

The heavily revised second edition (1877) shortens the title to The Various Contrivances by which Orchids are Fertilised by Insects, dropping the opening 'On,' 'British and Foreign,' and the closing clause on intercrossing, and incorporates new material including additions drawn from Darwin's 1869 French edition; it is a different, later text, not a reprint of the 1862 book.
