To quickly assess the difficulty of the text, read a short excerpt:
Muricata, with small corollas and narrow leaves, was introduced in the year 1789 by John Hunnemann, and 0. Suaveolens, or sweet- scented primrose, a form very similar to the biennis, about the same time, in 1778, by John Fothergill. This form is met with in dif- ferent parts of France, while the biennis and muricata are very common in the sandy regions of Holland, where I have observed them for 522 Mutations more than 40 years. They are very constant and have proven so in my experiments. Be- si...des these three species, the large-flowered evening-primrose, or Oenothera Lamarckiana, is found in some localities in Holland and elsewhere. We know little concerning its origin. It is supposed to have come from America in the same way as its con- geners, but as yet I have not been able to ascertain on what grounds this supposition rests. As far as I know, it has not been seen growing wild in this country, though it may have been overlooked. The fact that the species of this group are subject to many sys- tematic controversies and are combined by dif- ferent writers into systematic species in differ- ent ways, being often considered as varieties of one or two types, easily accounts for it having been overlooked.
