quently, also, weeds, which, from their creeping roots, are difficult to extirpate. \11 parts of the world 

 produce them, from the cold regions of the north to the burning soil of the equator, Cuscuta is a singular 

 parasite, wholly destitute of leaves. The root of many is filled with a milky acrid juice, which is very 

 purgative. Scammony, jalap, and some other drugs, are the produce of Convolvulaceae. The roots of 

 Ipomce N a fl6rida, scoparia, and Quambclit, are stimulatory ; that of Ipomce v a Batatas, which is the sweet 

 potato of America and Southern Europe, and that of Ipomceva edulis are wholesome articles of food. Their 

 botanical characters are very nearly the same as those of Polemoniacea?. Cuttings, divisions, or i

 True Boraginea? are chiefly herbaceous plants, with alternate exstipulate leaves, the surface of which is 

 covered over with minute asperities, and with flowers arranged in one-sided spikes or racemes, occasionally 

 solitary. Each flower has also four distinct little nuts or seeds, as they are commonly called. Some Echiums 

 and a few more are shrubs. They are found abundantly in Europe, Siberia, and the north of Africa, less 

 commonly in India, and the equinoctial parts of the world; in some quantity in North America, and in 

 tolerable abundance in New Holland. Within the tropics the order is principally represented by Heliotropiums 

 and Tournefortias ; in colder latitudes by Anchusas, Cynoglossums, herbaceous Echiums, and the like. 

 Some are mere weeds, quite unworthy of culture ; others are eminently beautiful, as many Echiums, 

 Onosmas, Onosmodiums, Symphytums, and others. In general they are mucilaginous and emollient, qualities 

 which are especially abundant in the root of Symphytum and Cynoglossum. Pure nitre has been found in 

 several plants of the order. A red colour is given out by ^4nchusa tinctoria, iithosptrmum tinctorium, and 

 0n6sma echioldes, which is used in dyeing. Several plants are employed on the same account in America. The 

 Hydrophylleaa are often considered as distinct, on account of their capsular fruit and cartilaginous albumen. 

 One or two of these are pretty plants, but most of them mere weeds. Cuttings, division, and seeds.

 divide them. Little is known of their properties, except that the flesh of their fruit is emollient and muci- 

 laginous. The nuts of C6rdia Sebestena are employed sometimes as laxatives. Cuttings.

 The baneful nightshade represents this order, which participates very generally in its qualities, although 

 they are frequently hidden beneath a fairer form, and often much mitigated. Many of the Solanums are very 

 handsome. The Verbascums, Daturas, and Solandras are all plants of great beauty, although the former, on 

 account of their frequency, are despised in gardens. Capsicums are famous for their pungent fruit and seeds ; 

 Brunsfelsias for their fragrance, and Nicotianas, or Tobacco, for their foetor. The leaves, indeed, of the whole 

 order are disagreeably scented. The usual effect of Solanea? is narcotic; but it is thought that this has been 

 exaggerated, on account of the intense and deleterious properties of A'tropa Belladonna. These, accord- 

 ing to the observations of Vauquelin, depend upon the presence of a bitter nauseous matter which is soluble 

 in spirits of wine, forming with tannin an insoluble compound, and giving out ammonia when decomposed by 

 fire. Notwithstanding the narcotic power of the roots of the Mandrake, the Belladonna, and others, those of 

 the Potato are found to contain an abundant fa?cula, which is among the most valuable food of man. The 

 leaves of many Solaneae are exciting and narcotic, but in very unequal degree, as in Tobacco, Physalis, 

 Henbane, &c. ; those of the Nightshade excite vertigo, convulsions, and vomiting. The juice of Strambnium 

 is given in North America, in doses of from twenty to thirty grains, in cases of epilepsy. The fruit of 

 Physalis AlkeMngi is a veterinary diuretic ; that of P. edulis is used in tarts ; that of Solanum Lycop^rsicum, 

 and Melongena, is served at table in various forms, under the name of Tomatoes and Aubergines. Cuttings, 

 division, and seeds.
