Abstract
THE rust fungi evolve in genetic balance with their host plants, and inevitably reflect their interrelationships. Although rust investigations usually merely confirm accepted classifications, occasionally, like studies in comparative biochemistry, they may suggest modifications of accepted ideas. A few such suggestions have already been presented1, among them the indication that the occasional occurrence of Puccinia asparagion Alliumthrew doubt on Hutchinson's2transfer of Allieae to Amaryllidaceae, a disposition followed by several recent authors. Hutchinson maintained, with apparent reason, that the umbellate inflorescence with an involucre of bracts, seen in Allieae and typical Amaryllidaceae, was of greater significance than the position of the ovary. However, new and more significant evidence from the rust fungi requires a reconsideration of this disposition.
