Note 86 — Chapter XVII · ON THE GOOD EFFECTS OF CROSSING, AND ON THE EVIL EFFECTS OF CLOSE INTERBREEDING.
Reading edition
Mr. D. Beaton, in ‘Journal of Hort.,’ 1861, p. 453. Lecoq however (‘De la Fécond.,’ 1862, p. 369), states that this hybrid is descended from G. psittacinus and cardinalis; but this is opposed to Herbert’s experience, who found that the former species could not be crossed.
