 Fragrance is the predominant property of the jasmine, and has made it for ages the favourite of poets and 

 of the people ; this arises from the presence of an oil which can be extracted so as to retain its perfume. In 

 medicinal qualities, the jasmines do not differ materially from the last ; they are neatly distinguished by 

 botanists by the direction of their ovula, which are erect in Jasminea?, and pendulous in Oleina?. Cuttings.

Tropical trees, nearly allied to Apocynea?, and like them truly poisonous. The Strychnos nux v6mica 

 is remarkable for its bitterness and acrid deleterious effects, which are indicated not only when introduced into 

 the stomach, but still more violently when introduced into the system by inoculation. Theophrastas are fine 

 stove trees, with simple stems, and undulated spiny-toothed leaves, which are disposed in something like 

 whorls. Cuttings and seeds.

We now turn from the contemplation of plants endued with mild and agreeable properties, and fragrant 

 flowers, and often bearing food for man, to others which are among the most dangerous and fatal poisons; 

 whose juices though milky are not a wholesome and delicious beverage like those of Sapbteae,but, on the contrary, 

 acrid, caustic, or bitter. They are readily known by the twisted direction of the segments of the corolla, which 

 have been compared to the rays of a Catherine's wheel, whence they were called by Linneeus, Cont6rtae. By 

 far the greatest part of the order consists of tropical trees and shrubs ; a few Apocynums, Amsonias, and 

 Vincas, are natives of the colder zones of the earth. Many are elegant climbers, as the different species of 

 JEchites and Melodinus. The splendid Oleander belongs to JVerium ; the different species of Plumier/a, Cam- 

 erhria, Strophanthus, and Arduina are stove plants of the greatest beauty. The medicinal action of these 

 plants is highly powerful. In general, the Apocynea? are acrid, stimulating, and astringent ; these principles, 

 when in excess, act so powerfully on the nerves as to produce stupefaction. The root of Ophioxylon is very 

 bitter and purgative: under the name of snake-root it is used in India as an antidote to the bites of serpents. 

 The bark of Cerbera Mdnghas is purgative ; of Zchites antidysent^rica, and the Wrlghtia of the same name, 

 astringent and febrifugal ; the leaves of the V'mca. are so astringent, that they have been used successfully in 

 tanning ; those of ^ferium Oleander are said to abound in free gallic acid. The inspissated juice of a species 

 of Cerberfl, known in Mexico under the name of Ycotli. is a fatal poison.

 These differ from the last only in having the stamens united into a sort of fleshy crown, and the pollen 

 coherent in masses of a waxy substance like that of Orchideas; their properties, habit, and geographical 

 range, are much the same. Periploca is a singular instance of an asclepiadeous plant being a hardy shrub, 

 every other frutescent species of the order being natives of countries where frost is unknown. Hoya compre- 

 hends climbing plants, with waxen, clustered, odoriferous flowers distilling honey. Pergularia is valued for its 

 fragrance, Ceropegia for its singularity, and ^sclepias for beauty and hardiness. But the most extraordinary 

 genera of the order are Stapeh'a, Piaranthus, and Hue>ni«, in which the place of leaves is supplied by fleshy 

 short stems of various forms, and whose flowers are not less singular for their curious and complex organisa- 

 tion, than they are remarkable for their strange colouring and spotting, and offensive for their fcetor. The root 

 of Dipl61epis vomitorium, ^sclepias curassavica, Cal6tropis procera, and some others, is employed in different 

 countries for ipecacuanha. An infusion of the root of ^sclepias decumbens has the singular property of 

 exciting general perspiration; whence it is successfully used in Virginia for pleurisy. It is very singular 

 that, in a tribe of plants so generally poisonous as these are, the young shoots of some species should be 

 an article of food : of this nature are Pergularia ediilis, Oxystelma escul^nta, Hemidesmus indicus, and 

 several more. Cuttings or divisions.
