These are also known under the name of Hesperldece. They consist of trees or shrubs of the greatest beauty 

 and utility. The well-known orange and lemon are the representatives of the order, the characters of which 

 are so well defined that there is no material deviation from the type afforded by those species. The thick 

 leaves, articulated with the petiole, and abounding in transparent reservoirs of odoriferous oil, are the most 

 obvious peculiarities. The flowers are fragrant, and the fruit in all cases fleshy, and generally eatable. The 

 wood is particularly close-grained. The volatile oil contained in the reservoirs of the leaves and fruit possesses 

 powerful tonic and stimulating properties. M. Decandolle thus explains the singular structure of the fruit of 

 the orange. In the opinion of this learned botanist it consists, first, of a thick, valveless, indehiscent indusium 

 or coat, which is most likely to be considered a continuous torus. Secondly, of several carpella, verticillate 

 around an imaginary axis, often separable without laceration ; membranous, and either containing seeds only, 

 or filled with pulp, lying in innumerable little bags proceeding from the inner coats of the cells. Cuttings, and 

 sometimes by layers, budding, grafting, and inarching.

The whole of these abound in a resinous juice, and are in most cases glandular in some degree. Their leaves 

 are all dotted, and, which is very remarkable, the dots are often black, even upon the yellow petals. These 

 latter have a singular obliquity, which is not indicated by their outline, but by the arrangement of their 

 veins. The juice just noticed as abundant in this order is yellow, viscid, rather bitter, often purgative or 

 anthelmintic, and so very analogous to Gamboge, that the juice of Hypericum baccatum, and some other 

 Guiana species, has received the name of American Gamboge. Most Hypericineas are bitter, and slightly 

 astringent, whence they have been used as febrifuges. A small part of the order is tropical ; but in its most 

 genuine form it consists of herbaceous or undershrubby plants, delighting in the shade of groves and thickets 

 in the cooler parts of Europe and Asia. Nearly all the flowers are yellow j those of H. cochinchinense are 

 dull red. Seeds, division, or cuttings.

Trees or shrubs found in the hottest parts of the world, and well known by their thick entire opposite leaves 

 and resinous juice. In the countries where they grow they are of great importance. One, the Garcim'a 

 Mangoslana, bears a fruit, the equal of which is supposed not to exist. The well known Gamboge is the in- 

 spissated juice of Garcin&« Gambbgia, and, perhaps, other species ; the juice of others is found an efficacious 

 vermifuge, and also a remedy for the chiggers, one of the worst pests of equinoctial America. The bark and 

 fruit of many Garcinias are astringent. The unripe fruits of Grias caulifl6ra are pickled. The flowers of all 

 the order being showy, the foliage good, and the properties interesting, every species deserves cultivation.

Very curious half-climbing shrubs, all natives of hot countries. Some of them bear among the flowers, 

 which are large and showy, singular hollow bodies, like the pitchers of Sarracfema. The order has been well 

 illustrated by Sir.W. J. Hooker, in the 160th article of his Exotic Flora. Cuttings.

Little is known of this order. The species are tropical arborescent or climbing shrubs, with opposite simple 

 leaves, and small inconspicuous flowers. The genus Tonsdlla contains some species known in Sierra Leone as 

 bearing poisonous fruit. Cuttings.
