(1916) Teratology In Iris by Lynch

Teratology in Iris (see p. 203
).-I was much interested in the valuable information given by Mrs Armitage on the teratology of Iris flowers, but with regard to her belief that hybridity cannot encourage abnormality, I would say that, given a sufficient number of hybrids, between plants that can only cross with difficulty, it is sure to appear. The late Sir Michael Foster had once an Oncocyclus hybrid with flowers that might be described as a mix-up of parts. Bits of anther, I remember, were produced where they ought not to be, and, though I could hardly vouch for it after many years, I believe that even the leaves attempted to produce anthers. I have had a very similar case myself in Nicotiana but with regard only to the flowers. I -crossed N. Tabacum with, I think, N. affinis, and the resulting hybrid produced very much deformed flowers, and the flowers varied among themselves. They were chiefly N. Tabacum in appearance, but hybridity was unquestionable, I believe, and I should expect that crosses of N. Tabacum with another not nearly allied species might produce it again. I daresay I have to apologize to the Gardeners' Chronicle for not sending a note at the time. R. Irwin Lynch,
