The new evening primroses which have sprung in my garden from the old form of Oenothera Lamarckiana, and which have evidently been derived from it, in each case, by a single mutation, do not differ from their parent species in one character only, but in almost all their organs and qualities.

Oenothera gigas, for example, has stouter stems and denser foliage; the leaves are larger and broader; its thick flower-buds produce gigantic flowers, but only small fruits with large seeds.

The production of the dwarf evening primrose, or Oenothera nanella, is assumed to be due to one of the factors, which determines the tall stature of the parent form, becoming latent; this would, therefore, afford an example of retrogressive mutation.

The external causes of this curious period of mutability are as yet wholly unknown and can hardly be guessed at, since the origin of the Oenothera Lamarckiana is veiled in mystery.

Cast a glance as you hurry onwards on the _Oenothera pumila_, a kind of evening primrose, on the false Hellebore--the one-sided Pyrola, the Bladder Campion--_silene inflata_, the sweet-scented yellow Mellilot, the white Yarran, the Prunella with blue labrate flowers the Yellow Rattle, so called from the rattling of the seeds.
