The present paper is an attempt to trace, as far as possible from available data, the history of the Oenotheras, particularly the large-flowered forms, in cultivation. An effort is also made to recognize, as far as this can be done, the precise characters of the various forms which have been figured or described during the last three centuries. Such records of course vary greatly in accuracy and value, for they are contemporaneous with the development of the science of botany itself. Judging from the number of polynomials applied to them by different authors, the Oenotheras would appear to have been as variable then as they are now. And I may say that my cultures of Oenotheras derived from various sources indicate that at present many of these forms are no less variable or mutable than the O. Lamarckiana of DeVries' experiments.
