(We see in Table 5 6. that the long-styled flowers fertilised with pollen from the short-styled yield more capsules, especially good ones containing more than one or two seeds, & that these capsules contain a greater proportional weight of seeds then do the long-styled flowers fertilised with pollen from a distinct plant of the same form. So it is with the short-styled flowers, when treated in an analogous manner. Therefore I have called the former method of fertilisation a legitimate union, & the latter an illegitimate

[Forms of flowers, p. 26: "We here see that the long-styled flowers fertilised with pollen from the short-styled yield more capsules, especially good ones (i.e. containing more than one or two seeds), and that these capsules contain a greater proportional weight of seeds than do the flowers of the long-styled when fertilised with pollen from a distinct plant of the same form. So it is with the short-styled flowers, if treated in an analogous manner. Therefore I have called the former method of fertilisation a legitimate union, and the latter, as it fails to yield the full complement of capsules and seeds, an illegitimate union."]
