Genus 1, Species 1 ; Hot-house Species 0 ; Green-house Species 1 ; Hardy Ligneous Species 0 ; 

 Hardy Herbaceous Species 0. J 0 feet ; j£ 0 feet ; =fe 0 feet. 



This order contains only three genera, Chailietia, Leucusia, and Tapura. It agrees with Teiebinthaceas in 

 being furnished with a corolla and calyx. Fruit furnished with a dry covering, including a two or three celled 

 nut, each cell containing one pendulous seed. Shrubs with entire alternate leaves, furnished witli stipules and 

 axillary and terminal panicled racemes of small white flowers ; chiefly natives of tropical Africa and its islands. 

 The kernel of the fruit of Chaillet/a toxicaria is used by the natives of Sierra Leone for poisoning rats and 

 mice. Cuttings.

The plants contained in this order are very imperfectly known. It differs from the preceding in the seeds 

 being erect, not inverted, as well as in the capsules being 2-valved. Trees with alternate entire leaves, natives 

 of Asia. Cuttings.

This order is, notwithstanding the labours of several botanists, in a very confused state; from want of 

 sufficient knowledge of many of the genera, which have been hitherto imperfectly described, it is difficult 

 either to determine the value of the characters assigned to the tribes, or the dignity of the tribes themselves. 

 All the species are shrubs or trees, with alternate exstipulate leaves, and inconspicuous flowers, and abound 

 in a balsamiferous resin, which is chiefly present in the leaves and bark, and from which the denomination of 

 the order has been derived. Notwithstanding the minuteness of their flowers, many of the species are valuable 

 as ornamental plants, on account of the beauty of their foliage, others for the sake of their utility in arts or 

 medicine, and others for their fruit. The Cashew and the Pistachio are valuable for their nuts, which 

 are well known articles in the markets of Europe. The Spondias and Mango are equally famous in the tropics. 

 The well-known balsam of Mecca is the produce of the Balsamodendron gilead^nsis ; and balm of Acouchi, 

 of the I'cica heterophylla ; gum comes from^myris elemifera and I'cica leptophylla ; mastich from Pistacia 

 atlantica and Lentiscus ; and Venetian turpentine fromPistacia Terebinth us. Scbinus Mblle produces a resin, 

 which in Peru is used as a dentrifke, as myrrh is with us. Some of the best varnishes are prepared from the 

 exudation of I'cica guiane~nsis, A'hus vernix, copalfina, Melanorrhce r a, and others; the finest kinds of incense 

 are also afforded by plants of this order, such as the wood and resin of the different species of I'cica, of Amyris 

 balsamifera, and of Canarium commune, the Coumia, which is used in Guiana for such purposes, and finally, 

 the Boswelh'u serrata, which is the true frankincense of Indian temples. But among the fragrant and whole- 

 some plants of which the order chiefly consists, lie concealed others in which acrid and poisonous qualities 

 no less abound. Such are several species of Phus, the juice of which produces blisters upon the skin ; 

 and the Amyris toxifera, the juice of which is accounted poisonous. To conclude this long list of the uses 

 and dangers of Terebinthacea?, the bark of Phiis glabra is used as a febrifuge and as a mordant for red 

 colors, and that of Phus Coriaria as a powerful means of tanning the skins of animals. Cuttings, layers, 

 and seeds.

The family to which the various kinds of pulse belong is one of the most familiar to the world, and at the 

 same time one of the most useful to mankind. Their papilionaceous flowers characterise a large number, and 

 their pods and pinnate leaves the remainder, with a few exceptions which it is not necessary to particularise. 

 As objects of ornament, many are possessed of unrivalled beauty, for example, among hardy flowering trees, 

 the Robima and the Laburnum ; among shrubs, for decorating the borders of the flower-garden, the various 

 tribes of Cytisus, Caragana, Colutea, Amorpha, and others ; among hardy climbers, the far-famed Wistaria of 

 China, and its sister of North America, with the species of the herbaceous genera V icia and Lathyrus ; and, 

 lastly, among hardy herbaceous plants, the numerous species of Lupinus and Astragalus. Great, however, as 

 is the beauty of the Leguminbsae which can brave the inclemencies of the seasons of Northern Europe, it must 

 give way before the splendor and elegance of their brethren of the tropics. The flowers of the Erythrlna, or 

 Coral tree, are of the deepest crimson, and borne in profusion upon some of the loftiest trees of the forest. 

 The Bauhinias, with their twin leaves, hang in festoons of flowers from branch to branch, and are only 

 rivalled by the less vigorous and elegant, but more richly colored blossoms of the Mucunas. But all these, 

 with their broad heavy foliage and gaudy colors, are far surpassed by the rugged trunks, trembling airy 

 foliage, and golden flowers of the fine-leaved Acacias, which cast a charm over even the most sterile deserts of 

 burning Africa. While the forests of hot countries are thus indebted to species of this order for their timber, 

 the meadows and pastures of the same latitudes are enamelled with the flowers of myriads of Hedysarums 

 and Desmodiums, and animated by the wonderful motion of sensitive plants. As in our own country, the gayest 

 part of our scenery is in many places indebted to the yellow flowers of our furze and broom, so in other 

 countries the same effect is produced by other genera of Leguminbsa;; by Liparia, Borbum'a, and Aspalathus
