Baillon, 'Adansonia,' v, p. 177, 'Sur la regularite transitoire de quelques fleurs irreg.,' shows that during the development of some flowers which begin and end by being irregular, there is an intermediate state when all the parts are regular. Helye, 'Revue Horticole,' Sept., 1868, p. 327. In this last paper, published as this sheet is going through the press, the author states that he has raised from seed three generations of plants of _Antirrhinum_ with regular spur-less flowers. The original wild plant was only partially peloric, but all the flowers produced on its descendants were regular. FOOTNOTES: [221] "On the existence of two forms of Peloria," by M. T. Masters. 'Nat.
