Here we are on the limits of Monocotyl£dones and Dicotyledones. The species are herbaceous or half- 

 shrubby plants, with simple, often reniform, leaves ; and mottled grotesque flowers, usually brownish purple. 

 Their roots are all bitter, and possessed of tonic and stimulating properties ; but the degree in which they 

 exist in different species is not at present ascertained. The Aristolochias have been in former days praised as 

 emmenagogues, and many are still used in South America as a remedy for the bite of serpents. A sarum 

 europae\jm is a purgative and emetic when fresh, but its powers are much diminished by drying ; its dried 

 leaves are occasionally used by the country people in some parts of England as a sternutatory. Division and 

 cuttings.

 The famous pitcher-plants of China and the East Indies belong to Nepenthes, and bear leaves, the 

 extremities of which are hollowed out into cup-like appendages that are generally filled with water, which 

 seems as if confined within them by a little lid by which the pitchers are surmounted. Seeds.

 Weeds and lofty trees, of such varied appearance and property, that it is scarcely possible to frame a brief 

 character by which they can be expressed. Their vegetation in cold countries is mostly herbaceous, in hot 

 countries frutescent or arborescent ; their juice is milky, and their flowers mostly inconspicuous. It is for 

 their medicinal properties that they are chiefly known, and these are as various as their aspect ; mostly, how- 

 ever, dangerous, and always to be suspected. In a few of them the smell and taste are aromatic ; but in most 

 there is either no smell or it is nauseous, and the taste constantly acrid and pungent. Some possess also an 

 acrid limpid fluid, which is given out by the leaves when touched. Many of them act strongly upon the 

 kidneys, as several species of Phyllanthus, the leaves of Mercuria/is annua, and the root of /Zicinus communis. 

 Many are said to be powerful medicines in cases of dropsy. The bark of several Crotons, the wood of C'ruton 

 Ttglium and Buxus, the leaves of the same, and also of Cicca disticha, several Euphorbias, and others, are 

 recorded as sudorifics, and useful against syphilis ; as emetics, we find the roots of the Euphorbias, the juice 

 of Commia, A'nda, Mercurialis perennis, &c A great number are purgative, especially the leaves of Z?uxus 

 and Mercurialis, the juice of Euphorbia, Commia, Hura, the seeds of i?icinus, Crc ton Ttglium, A'nda, and 

 Jatropha. The effects of some others are so dangerous, particularly ifippomane, that it is not advisable to 

 administer them even in very small doses ; even in many Euphorbias it is difficult to draw a line between the 

 quantity in which they are poisonous, and that in which they are harmless or useful. The nature of their 

 poison is mostly acrid, occasionally, however, mixed with something narcotic, as is apparent from the effect of 

 those which are used for poisoning or rather stupefying fish. The purgative oil in which the seeds of many 

 are found to abound, has been determined to reside wholly in the albumen ; hence the embryo of some, as 

 Omphalea diandra, is eaten as nuts. Boiling or roasting has also the effect of dissipating their noxious effects ; 

 thus Janipha Munihot, than which there scarcely exists a more dangerous poison, affords a food when sub- 

 mitted to fire, called cassava, the flour of which is often used in London as a luxury for making puudings, 

 than which few are reputed to be more wholesome. But the most curious of all the products of Euphorbiacea? 

 is the Caoutchouc, that singular substance which, although the produce of dangerous acrid trees, possesses 

 nothing whatever which has been found capable of acting upon the human system in whatever way applied, 

 which is unalterable either in air, in water, or in spirits, although it softens at a high temperature. It is 

 chiefly produced by Siphonia elastica, but also exists in the juice of very many others, as Excaecaria agallocha, 

 i/ippomane Mancinella, Hiira crepitans, Sapium aucuparium, Plukenet/rt volubilis, the Jatrophas, Mabea, 

 Omphaleas, and many others. Tournesole, another curious chemical preparation, is the juice of Croton 

 tinctbrium, but is also found in several others. Many other properties belong to this order, which it would be 

 too long to detail in this place. The curious reader will find ample information in the medical division of 

 M. Adrian de Jussieu's monograph of the order, from which most of the foregoing remarks are taken. Cuttir.gs,
