Most carnivorous plants stand alone in the plant world not only in their unique method of 1SUPPLEMENT nutrition but in the extraordinary degree to which the leaves have become changed from our idea of a typical leaf-blade to meet this end. Some have evolved into pitcher forms, often 2REMINISCE of strange flowers, while others have developed the power of movement, reminding one in their actions of steel traps, mouse traps, or even sea anemones. The 3USUAL to bizarre appearance of most is curious enough, but the varied and often 4ASTONISH artful methods employed in the 5SEDUCE of the prey frequently combined with added 6REFINE of technique which may be peculiar to a species, cannot fail to fascinate. Carnivorous plants occur both amongst the flowering plants and in the Fungi. While some reference will be made to the principal trap types of the latter, they remain a subject in themselves, and it will be the former which concerns us here. On these, a number of works have already been published in English, mainly in the United States. While the 7MAJOR of these have been brief works of a popular kind there have been some 8NOTE exceptions. Quite apart from the interest provided by their traps, it should not be forgotten that they are attractive plants in themselves; some are indeed beautiful.
