[92] Mr Hurst, of Burbage, tells me that in varieties having coats green or white, e.g. American Wonder, the white coats are mostly from early, the green from later pods, the tints depending on conditions and exposure.
[93] In the first case Knight’s Marrow with Victoria, both ways; in the second Victoria with Telephone, both ways.
[94] Gärtner’s macrospermum was evidently one of these, though from the further account (p. 498) it was probably more wrinkled. There are of course mange-touts which have perfectly round seeds. Mendel himself showed that the mange-tout character, the soft constricted pod, was transferable. There are also mange-touts with fully wrinkled seeds and “grey” peas with small seeds (see Vilmorin-Andrieux, Plantes Potagères, 1883).
[95] Correns found a similar result.
[96] “Entweder kugelrund oder rundlich, die Einsenkungen, wenn welche an der Oberfläche vorkommen, immer nur seicht, oder sie sind unregelmässig kantig, tief runzlig (P. quadratum).”
[97] The colour is the peculiarly deep yellow of the “grey” mange-tout.
[98] It is certainly subject to considerable changes according to conditions. Those ripened in my garden are without exception much larger and flatter than Vilmorin’s seeds (now two years old) from which they grew. The colour of the coats is also much duller. These changes are just what is to be expected from the English climate—taken with the fact that my sample of this variety was late sown.
[99] Thus avoiding the error of Seton, see p. 144. There is no xenia perhaps because the seed-coat of mother was a transparent coat.
[100] As heterozygotes often do.
[101] Dominance of the purple form.
