The nearest affinity of this order is probably with Sapindacea?. It is particularly distinguished by the 

 stamens being united into a tube bearing the anthers. The leaves are usually pinnated, .and most of the 

 species, which are all either trees or shrubs, are natives of tropical forests. 3/elia bears bunches of fine lilac- 

 colored flowers, but few of the genera are interesting on account of theii inflorescence. The qualities of the 

 different species are little known. The bark of Guarea trichilidides is said by Aublet to be purgative and 

 emetic. The pulpy fruit of 3/elia Azedardch is said to be poisonous ; both this part and the inner bark have 

 been used as anthelmintics either in substance or in decoction. It is asserted by Michaux, that the pulp that 

 surrounds the kernel is considered in Pekin a specific in scrophulous cases. The oil expressed from the 

 seeds of the same plant is said to have strong antispasmodic powers. Cuttings or layers,

The vine is the type and representative of this order. Cissus and Ampelopsis differ little from it in botanical 

 characters, and not at all in habit. The common grape is the only species that bears really good fruit ; the 

 American kinds, with large fleshy berries, being spoiled by a disagreeable foxy flavor, which is not found to 

 be removed by cultivation. Cuttings.

The Geraniums are well known to all gardeners for their beauty, and the facility with which hybrid 

 varieties are produced among them. Geranium and Erodium are chiefly natives of the northern hemisphere, 

 and Pelargonium of the southern. Different as they appear from Vinifera? in most respects, there are some 

 points in which a curious resemblance may be found between the two orders. The young stems of both are 

 articulated and separable at the articulations ; and the lower leaves are opposite, while the upper ones are 

 alternate. In Geraniacea? no tendrils are produced, but the peduncles are opposite to the leaves, as in Fitis, 

 and occupy the place of tendrils. M. Decandolle observes, that of the true Geraniacea?, some are slightly 

 acid, especially those of which the leaves and bark are succulent ; several exhale a resinous smell which is 

 sometimes agreeable, but occasionally so powerful as to be unpleasant. The resinous principle is so abundant 

 in Sarcocaulon L'Heritien, that its stem burns like a torch, and exhales an agreeable perfume. The most 

 common property of European geraniums is to be astringent, which is chemically determined by their juice 

 being blackened by sulphate of iron ; this is particularly remarkable in G. Rdbextianvm and sanguineum, 

 which are both accounted vulnerary, and in E. rnoschatum, G. pratense, and others, in which it is united to a 

 slight aromatic principle, whence 'they have been recommended for various purposes, and among others for 

 removing calculous disorders. The astringent property of the geraniums is also present in G. maculatum, 

 which grows in much abundance about Philadelphia ; the root of this plant, boiled in milk, is used for the 

 cholera in children. Barton is of opinion, that it would be a good substitute for gum kino in nephritis and 

 obstinate diarrhoeas. Cuttings, division, or seeds ; or sometimes by cuttings of the roots.

These are climbing or trailing herbs with handsome solitary axillary flowers, and fleshy stems and leaves. 

 They are distinguished from Geraniaceas by their stamens being separate, and not agreeing in number with the 

 petals ; by their axillary flowers, and fleshy indehiscent fruit. It is very curious, that this is the only order 

 in which the peculiar acrid flavour of CruciferEe is found to exist. Tropas^olum pentaphyHum, with probably 

 olher species, is a powerful antiscorbutic. All are natives of shady places in various parts of South America. 

 The roots of some are fleshy and eatable. Seeds or cuttings.

The flower of this order has been remarked by a learned botanist to be that of Fumariacea?, the capsule of 

 O'xalis, the embryo of ilnum, and the habit peculiar. The well-known elastic spring with which the seeds 

 are ejected constitutes a principal character of the order. All the species are annuals, with the exception of 

 Impatiens fruticosa ; they delight in moist hot situations, generally within the tropics; and are remarkable 

 for the singularity and varied colors of their flowers. Seeds, and sometimes by cuttings.
