197 ページ - Each side of the leaf is a little concave on the inner side, where are placed three delicate, hairlike organs, in such an order, that an insect can hardly traverse it, without interfering with one of them, when the two sides suddenly collapse and enclose its prey with a force surpassing an insect's efforts to escape. The fringe or hairs of the opposite sides of the leaf interlace, like the fingers of the two hands clasped together.
197 ページ - ... the prey with a force surpassing an insect's efforts to escape. The fringe or hairs of the opposite sides of the leaf interlace, like the fingers of the two hands clasped together. The sensitiveness resides only in these hairlike processes on the inside, as the leaf may be touched or pressed in any other part without sensible effects. The little prisoner is not crushed and suddenly destroyed, as is sometimes supposed, for I have often liberated captive flies and spiders, which sped away as fast...
197 ページ - It is found in great abundance for many miles around Wilmington, in every direction. I venture a short notice of this interesting plant, as I am not aware that any popular description of it has been published in this country. The leaf, which is the only curious part, springs from the root, spreading upon the ground, or at a little elevation above it. It is composed of a petiole or stem with broad margins, like the leaf of the orange tree, two to four inches long, which at the end, suddenly expands...
5 ページ - The design of this work is to illustrate the Botany of the United States by figures, with full analyses of one or more species of each genus, accompanied by descriptive generic characters and critical observations. The figures are in all cases drawn directly from nature.
198 ページ - I have not examined sufficiently to pronounce on the universality of this result, it will require further observation and experiment on the spot, to ascertain its nature and importance. It is not to be supposed however, that such food is necessary to the existence of the plant, but like compost, may increase its growth and vigor.
198 ページ - Dionaea muscipula. I therefore deem it no credulous inference, that its leaves are constructed for that specific object, whether insects subserve the purpose of nourishment to the plant or not. It is no objection to this view that they are subject to blind accident, and sometimes close upon straws as well as insects. It would be a curious vegetable indeed, that had a faculty of distinguishing bodies, and recoiled at the touch of one, while it quietly submitted to violence from another.
127 ページ - ... genera of very different forms, some of which may, with sufficient clearness, be described. In many cases no other appearance exists ; in some, however, the axis of the septum resembles either a single nerve, or two distinct parallel nerves ; and from this axis, whether formed of one or two nerves, tubes having the appearance and ramification of the veins of a leaf, and which generally terminate within the margin, not unfrequently proceed.
197 ページ - Carolina. Dr. Bachman has received it from Georgetown, SC ; and Mr. Audubon informed me, with the plant before us, that he has seen it in Florida, of enormous size.
197 ページ - Pinckney, that it grows along the lower branches of the Santee in South Carolina. Dr. Bachman has received it from Georgetown, *SC ; and Mr.
106 ページ - Immediately below the surface it is very smooth and polished, and still lowerjt is beset with sharp hairs, in most species long and slender, or else like those of the hood (in S. Drummondii extremely short and close), but in all pointing directly downwards so as to allow insects to descend, but effectually to obstruct their return. The inner surface of the hood is likewise lined with stiff and sharp retrorse bristles, which subserve a similar purpose, except in S. flava, which is smooth; but in that...
