Showy trees, natives of India, with the branches usually spinescent, alternate exstipulat'e ovate-lanceolate, 

 acuminate feather-nerved quite entire leaves, and the flowers which are white rising in fascicles from the 

 axilla? of the leaves ; the fruit is edible. The order only consists of one genus ; it differs from Myrtacea? in the 

 petals being more numerous and in the anthers being adnate, as well as in the fruit being one-celled. Cuttings.

This consists at present of a single genus, which was formerly referred to Myrtaceas, but which has lately 

 been separated with much acuteness by Mr. Don. The species are hardy ornamental shrubs, natives of North 

 America, with white flowers ; in some cases fragrant. Nothing is known of their properties. Cuttings and 

 layers.

Dotted leaves with marginal ribs, and an inferior ovarium and single style, are the great features of 

 Myrtacea?. They are all fine evergreen shrubs or trees, generally bearing white flowers, and in the first section 

 producing fleshy fruit. It is there that the Allspice, the Clove, the Rose-apple, and the Guava find their 

 station, by the side of the common myrtle. The section with capsular fruit comprehends, with the exception 

 of the gigantic Eucalyptuses, almost wholly handsome hard-wooded New Holland or South Sea shrubs, witli 

 white or crimson flowers and stamens : yellow flowers are very uncommon. The volatile oil contained in the 

 \ttle reservoirs of the bark, the leaves, and the floral envelopes, gives these plants the fragrance which has 

 caused them to be celebrated by poets of all ages. It is very aromatic, a little acrid, and slightly tonic and 

 stimulant, whether it is under the form of Cajeputi oil, the produce of Melaleuca Leucadcjndron, or of oil ot 

 cloves or of myrtle. In the clove this oil is so abundant as to constitute nearly a fifth of the whole weight ot 

 the calyxes that produce it. There is also a considerable proportion of astringent principle in these plants ; in 

 the bark of A/yrtus ZJ'gni and multiflijra of Chile, and Jambbsa malaccensis, it is so abundant as to render a 

 decoction of those plants of great use in cases of dysentery. Eucalyptus resinifera produces an astringent 

 subresinous substance resembling gum kino. The leaves of the Chilian myrtles, Leptospermum scoparium, 

 and some other species, have been used as substitutes for tea. Cuttings and seeds.

 Here is the station of the gourd, the melon, and the cucumber, succulent climbing vegetables, the fruit ot 

 which administers to us many of our comforts and necessities. The importance of the gourd in hot countries 

 is of the highest degree, where, from the nature of the climate, few of those culinary vegetables that are so 

 abundant in the north can be made to succeed. Among these tribes of climbing annuals, the papaw tree is a 

 remarkable deviation from the ordinary character of the vegetation. Its fruit, however, and flowers are in all 

 respects those of Cucurbitacea?. The fruit is mostly sweet, watery, refreshing, and pleasant to the palate ; but 

 the coloquintida gourd, the spirting cucumber, and the Trichosanthes amara, are all possessed of violent 

 bitter, drastic, purgative qualities, which are, indeed, to be found, in a slight degree, even in the mildest of 

 the eatable gourds. M. Decandolle observes, that as the violent action of the Colocinth resin is much 

 softened by the mixture with it of gum, it is probable that the difference in the fruits of the order depends 

 upon the different proportions between these two substances. The seeds of the gourd, like those of the 

 passion-flower, possess none of the properties of the pulp ; they are sweet and nutty, and readily form an 

 emulsion. The roots of the bryony are purgative, but also contain a wholesome fa?cula. It is said that the roots 

 of a species of bryony are eaten in Abyssinia, after being merely boiled. There are some Cucurbitacea?, the 

 roots of which are intensely bitter ; those of one of this description are used in Peru, to remove the pains 

 attendant upon inveterate venereal disorders. Seeds.
