Some plants give about one-third scintillans and two-thirds lamarckiana, while the progeny of individuals of another strain show exactly the reverse proportion. Two points deserve to be noticed. First the progeny of the scintillans appears to be mutable in a large degree, exceeding even the lamarckiana.
Soon the smaller ones show their deeper green and broader leaves, and thereby display the attributes of the scintillans. The other grow faster and stronger and exhibit all the characteristics of ordinary lamarckianas. The numerical proportion of these two groups has been found different on different occasions.
When they had had their breakfast, and the old people were ready for church where they would listen a little, sleep a little, sing heartily, and hear nothing to wake hunger, joy or aspiration, Dawtie put a piece of oat-cake in her pocket, and went to join Andrew where they had made their tryst and where she found him waiting at his length in a bush of heather, with Henry Vaughan's "Silex Scintillans," drawing from it "bright shoots of everlastingness" for his Sabbath day's delight.
It had been very bad weather, and he and Sydney seemed to have been doing a great quantity of fretwork together, and to have had much music, only chaperoned by old Sir James, for Fordham had been paying for his exertions at the wedding by being confined to his room. He had sent Babie a book, namely, Vaughan's beautiful "Silex Scintillans," full of marked passages, which went to her heart.
They obey the same general laws, become active under similar conditions, some of them being more easily awakened than others. The germs of the oblonga, lata and nanella are especially irritable, and are ready to spring into activity at the least summons, while those of gigas, rubrinervis and scintillans are far more difficult to arouse.
They repeat their character, from pure seed, only in part of the offspring. I have tried to deliver the scintillans from this incompleteness of heredity, but in vain. The succeeding generations, if produced from true representatives of the new type, and with pure fertilization, have repeated the splitting in the same numerical proportions.
I have already given the names of the only two forms, which deserve to be mentioned here. One of them is called scintillans or the shiny evening-primrose, because its leaves are of a deep green color with smooth surfaces, glistening in the sunshine. On the young rosettes these leaves are somewhat broader, and afterwards somewhat narrower than those of O. lamarckiana at the corresponding ages.
All about the room lay books that were not of my culling, from the oak cases, whose every door stood ajar, novels innumerable, "The Arabian Nights," Vaughan's "Silex Scintillans," with a scarlet leaf laid in against "Peace," and "Tennyson" turned on its face at "Fatima," a heavy volume of French moral philosophy, a Methodist hymn-book, Sir Thomas Browne's "Hydriotaphia," and a gilded red-bound history of "Five Little Pigs."
But, on the contrary, the atavists, which are here the individuals with the stature and the characteristics of the lamarckiana, have become lamarckianas in their hereditary qualities, too. If their seed is saved and sown, their progeny does not contain any scintillans, or at least no more than might arise by ordinary mutations.
The other head comprises two fertile forms, O. scintillans and O. elliptica, which may easily be fertilized with their own pollen, but which gave a progeny only partly similar to the parents. The Oenothera lata is a very distinct form which was found more than once in the field, and recently in a luxuriant flowering specimen.
