[26] One species possesses a beautifully brownish-red coloured pod, which when ripening turns to violet and blue. Trials with this character were only begun last year. [Of these further experiments it seems no account was published. Correns has since worked with such a variety.]
[27] [This is often called the Mummy Pea. It shows slight fasciation. The form I know has white standard and salmon-red wings.]
[28] [In my account of these experiments (R.H.S. Journal, vol. xxv. p. 54) I misunderstood this paragraph and took “axis” to mean the floral axis, instead of the main axis of the plant. The unit of measurement, being indicated in the original by a dash (′), I carelessly took to have been an inch, but the translation here given is evidently correct.]
[29] [It is somewhat surprising that no mention is made of Thrips, which swarm in Pea flowers. I had come to the conclusion that this is a real source of error and I see Laxton held the same opinion.]
[30] [This also happens in Sweet Peas.]
[31] [Mendel throughout speaks of his cross-bred Peas as “hybrids,” a term which many restrict to the offspring of two distinct species. He, as he explains, held this to be only a question of degree.]
[32] [Note that Mendel, with true penetration, avoids speaking of the hybrid-character as “transmitted” by either parent, thus escaping the error pervading modern views of heredity.]
[33] [Gärtner, p. 223.]
[34] [It is much to be regretted that Mendel does not give the complete series individually. No one who repeats such experiments should fail to record the individual numbers, which on seriation are sure to be full of interest.]
[35] [This paragraph presents the view of the hybrid-character as something incidental to the hybrid, and not “transmitted” to it—a true and fundamental conception here expressed probably for the first time.]
