Inga. This is an American name adopted by Marcgraaf. A fine genus of plants, remarkable for their beautiful foliage and flowers; but in cultivation they seldom blossom. I. purpurea is a remarkably elegant plant, and so is Inga biglobosa. 1. unguis-Cati, the Cat's claw, Mimosa, is so called from the form of its curved spines. All the species require the greatest heat of the bark stove; they increase very slowly by cuttings. 2124. Mimosa. Said to be derived from μiμoς, a buffoon, because the leaves of the sensitive species appear as if to play with the hand that touches them.

The cause of the well known motion in the leaves of the sensitive plant, has been the subject of many ingenious explanations; but it has not been treated by any botanist with so much ingenuity and address as by Dr. Dutrochet, whose theory we give, as explained by Mr. Lindley in the Botanical Register. M. Dutrochet states, that having ascertained hot nitric acid to possess the power of separating and reducing to its simplest form the whole mass of vegetable tissue, and that the action of the same acid produced other effects equally advantageous for the examination of the most obscure parts of vegetable structure, he was induced to give his attention to that of the Mimosa pudica, in the hope of gaining some evidence respecting the cause to which its sensibility is to be ascribed. Beginning with the pith, he observed a considerable number of minute globules of a greenish color, intermingled among the cells, and adhering to them in an irregular manner. After attempting to shew the probability of these globules having deceived M. Mirbel in various points of his analysis of vegetation, and especially in regard to the pores, which that botanist supposes to exist in the cellular tissue of plants, Dr. Dutrochet proceeds to remark, that the application of hot nitric acid to these globules renders them perfectly opaque, whence he concludes, that they are, in fact, minute cells filled with a particular fluid, which is subject to become concrete by the application of acids. Now, it is known, that such fluids as are thus altered by acids, are usually dissolved and liquefied again by the application of alkalies. A few drops, therefore, of a solution of hydrate of potash were suffered to fall upon a portion of the pith on which nitric acid had been acting, and the mixture was exposed to the heat of a lamp. Being examined after a few minutes, the globules were found to have resumed their natural appearance. This curious fact indicated, in the opinion of Dr. Dutrochet, a strong and unexpected point of analogy between plants and animals. According to the microscopical researches of some modern observers, it has been ascertained that all the organs of animals are composed of a conglomeration of minute corpuscles, similar to those just described; the corpuscles which constitute the muscles are soluble in acids, but those which compose the nervous system are insoluble in the same acids, and only soluble in alkalies. Now, as the chemical properties and the external appearance of the particles scattered among the cellular tissue of plants, and constituting the nervous system of animals, are the same, the author is induced to infer, that the spherical particles of plants are, in fact, the ORDER I.

This hypothesis receives additional strength from the great similarity which exists between the medullary substance of the brain of Mollusca Gasteropoda and the cellular medullary tissue of plants. In pursuit of this idea, Dr. Dutrochet made a variety of experiments upon the sensitive plant, the results of which seem to be these. - The principal point of locomotion, or of mobility, exists in the little swelling which is situated at the base of the common and partial petioles of the leaves; this swelling is composed of a very delicate cellular tissue, in which is found an immense number of nervous corpuscles; the axis of the swelling is formed of a little fascicle of tubular vessels. It was ascertained by some delicate experiments, that the power of movement, or of contraction and expansion, exists in the parenchyma and cellular tissue of the swelling, and that the central fibres have no specific action connected with the motion. It also appeared that the energy of the nervous powers of the leaf depended wholly upon an abundance of sap, and that a diminution of that fluid occasioned an extreme diminution of the sensibility of the leaves. Prosecuting his remarks yet further, the author ascertained, that in the motion of the sensitive plant, two distinct actions take place, the one of locomotion, which is the consequence of direct violence offered to the leaves, and which occurs in the swellings already spoken of; the other of nervimotion, which depends upon some stimulus applied to the surface of the leaflets, unaccompanied by actual violence, such as the solar rays concentrated in the focus of a lens. As in all cases, the bending or folding of the leaves evidently takes place from one leaf to another with perfect continuity; it may safely be inferred, that the invisible nervous action takes place in a direct line from the point of original irritation, and that the cause by which this action of nervimotion is produced, must be some internal uninterrupted agency. This was, after much curious investigation, determined by the author to exist neither in the pith, nor in the bark, nor even in the cellular tissue filled with nervous corpuscles, and on which, he supposes, the locomotion of the swelling at the base of petioles to depend. It is in the ligneous part of the central system, in certain tubes supplied with nervous corpuscles, and serving for the transmission of the sap, that Dr. Dutrochet believes he has found the true seat of nervimotion, which he attributes to the agency of the sap alone, while he considers the power of locomotion to depend upon the nervous corpuscles alone.

Some of the species ripen seed; others may be increased by cuttings from the points of the young shoots planted in sand and kept closely covered. in sand and kept closely covered.

From δεσμη, a bond, and avθoς, a flower, on account of the fascicles of flowers, which seem as if bound up together. These plants are chiefly aquatic; a few are prickly; and they all have the habit of Mimosa. D. natans is used in China as a pot-herb; and is described by Loureiro, under the name of Neptunia oleracea. Willdenow, the author of the genus, observes, that the neuter florets have always a different color from that of the hermaphrodites, whence the spikes appear parti-colored, by which character the genus may be known at a distance. Culture as in Mimosa. D. natans should be grown in water. 2127. Acacia. This was the Greek name of some plant of the present genus, and not being appropriated, was taken by Willdenow, in his reformation of the old genus Mimosa, as the designation of one of his new divisions. This is one of the most ornamental families of the greenhouse plants, and some are curious as well as beautiful. A. Julibrissin, the Gul ebruschim, or rose of silk of the Persians, and the Gazia of Italian gardeners, is an elegant hardy tree with beautiful tufts of pink colored flowers, which resemble tassels of silken threads.

The decoction is afterwards evaporated by the heat of the sun, stirring it several times in the day; and when it is reduced to a considerable thickness, it is spread upon a mat or cloth, which has previously been covered with the ashes of cowdung. The mass is lastly divided into square or quadrangular pieces by a string, and completely dried by turning them in the sun, until they are fit for sale. This extract, when first introducd as a medicine into Europe, was named Terra Japonica, from the supposition that it came from Japan and was an earth." Medicinally catechu is one of the most valuable of the vegetable astringents; and as the dark colored contains the greater quantity of tannin, on which its astringency depends, it is to be preferred for medicinal use. It is employed with the best effects in dysentery and diarrhea, when the use of astringents is admissible; in alvine and uterine hæmorrhages, leucorrhœa, gleet, and in obstinate catarrhal affections. As a local astringent, it is used in sponginess of the gums, and aphthous ulcerations of the mouth and fauces, and we have found the slow solution of a small piece of it in the mouth, a certain remedy for the troublesome cough induced by a relaxed uvula hanging into and irritating the glottis. Dr. Paris recommends it as a dentifrice, especially when the gums are spongy.

It is a hard withered looking low tree, with a crooked stem, and a grey bark. The gum exudes naturally from the bark of the trunk and the branches, in a soft, nearly fluid state, and hardens in the air without losing its transparency. It is collected about the middle of December. It has a faint smell when first stowed in the warehouses, and is heard to crack spontaneously for many weeks. Medicinally gum exerts no action on the living system, but is a simple demulcent, serving to lubricate abraded surfaces, and involve acrid matters in the primæ viæ. In the solid form it is scarcely ever given, unless to sheath the fauces, and allay the tickling irritation which occasions the cough in catarrh and phthisis pulmonalis; in which cases a piece of it is allowed to dissolve slowly in the mouth. It is chiefly used in a state of mucilage.

According to Sweet, all the species of Acacia are of easy culture. Those of the hothouse he recommends to be grown in loam and peat. "Cuttings," he says, " of most kinds will strike root. From the strongest growing kinds, take off large cuttings at a joint, and plunge them in a pot of sand under a hand-glass in the bark-bed. ORDER I.

Of the smaller kinds take younger cuttings, and put them under a bell-glass, also plunged in heat. The sooner the plants are potted off after they are rooted the better. If they stay too long, the sand injures their roots: they should be kept under a close glass, and shaded for a few days after potting off, and exposed to the air by degrees." (Bot. Cult. 11.) The greenhouse species are particularly valuable as flowering for the most part in winter, or early in spring; they are very hardy and grow freely in loam, peat, and sand well drained. Cuttings of most kinds, Sweet observes, will root pretty freely, taken off in the young wood and planted in sand, under a bell-glass, and plunged in a little bottom heat. The kinds that do not root readily from cuttings may be increased by taking off roots, as large pieces as can be spared, and planting them in the same kind of soil as the old plants, when they should be plunged under a hand-glass in a little bottom heat. Most of the kinds might be propagated by that means. (Bot. Cult. 126.) 2128. Veratrum. Said by Lemery to be so called, because its root is vere-atrum, truly black. V. album has a fleshy fusiform root, beset with strong fibres, gathered into a head; this root and every part of the plant is POLYGAMIA MONŒCIA.
