This order differs from Crucifera in the capsules being unilocular and the stamens indefinite, a3 well as 

 iu the seeds being destitute of an umbilical cord. Weeds of no interest, except the iJeseda odorata for its 

 delicious fragrance. R. Luteola, a common annual in waste places, yields a yellow color fit for dyeing. All 

 natives of Europe and North Africa. Seeds.

 Differs from the preceding order in having an inferior ovarium, and in the seeds being furnished with 

 albumen. This order consists only of one genus, containing three species, natives of the south of Europe, 

 Nepal, and North America. They are strong coarse hardy perennials, with the appearance of hemp.

These are nearly related to Crucifera, of the properties of which they partake. Many are very pretty plants, 

 especially Cleome rosea, and the various species of CratseVa. The common caper is an elegantbush, 'remark- 

 able for its large white flowers and long purple stamens. The species are found occasionally in various parts 

 of the world The different kinds of G'apparis are reputed to be stimulating, antiscorbutic, and aperient. The 

 bark of the root of the common caper passes for a diuretic medicine. Several species of Cleome have an acrid 

 taste, which has been compared by travellers to that of mustard. The root of Cleome dodecandra is employed 

 as a vermifuge in the United States ; and the leaves produce an inflammation of the skin, whence they are 

 used in Cochin-China as a sinapism. Dec. Cuttings or seeds.

A very small order, formerly comprised in Tiliacea?. It is remarkable on account of the structure of its 

 fruit, to the inner lining of which the seeds are attached upon a branched placenta. Nothing is known of the 

 properties of the Flacourtias. The berries of Flacourtw Ram<sntchi are eaten in Madagascar. The order 

 consists entirely of small tropical trees or bushes. Cuttings.

The plants of this order are few in number, and not remarkable either for beauty or use. TheBixa Orellana 

 is chiefly known for producing the seed called in the shops Arnotta {Rocon, Ft.) and used for coloring 

 cheese ; the properties of the Arnotta are slightly purgative and stomachic. They are all bushes or small 

 trees, and mostly tropical. Azaras, Chilian shrubs with fragrant flowers, are not yet known in the gardens of 

 Europe. Cuttings.

The common rock roses of our gardens give an accurate idea of this order, which contains little else. They 

 are all very ornamental, and particularly well calculated for covering rockwork. They are natives of most 

 parts of the world in dry elevated places. The gum called Ladanum is the produce of some kinds of C'istus ; 

 it exhales a fragrant perfume when burnt, and possesses slightly tonic and stomachic properties. Cuttings or 



seeds.

This is one of the most favorite orders with gardeners ; consisting, as it chiefly does, of the Violet genus, 

 rrom which most of the others are recent dismemberments. The greater part are hardy herbaceous plants, 

 some of which are remarkable for their perfume, others for their brilliant colours, and all for their neatness. 

 They are natives of the temperate or cold zones of both hemispheres, often growing at great elevations above 

 the sea. Among them is a tribe called Alsodineffi, consisting of suffrutescent tropical plants ; but none of them 

 have been introduced into the gardens of this country. The attention of collectors should be directed to pro- 

 curing the shrubby Violaceae of Brazil, some of which possess great interest The medical properties of the 

 order are found principally in their roots, which appear to possess, in all cases, emetic properties, in a greater 

 or less degree. One of the Ipecacuanhas is the root of a Brazilian violet. M. Decandolle has the following 

 observations upon the affinities of the Violaries : — They are very nearly akin, he observes, to the Polygaleas 

 and Droseracea?, and especially to the Passifloreae. From the first they are distinguished by their unilocular 

 fruit, leaves furnished with stipules, and two-celled anthers; from Droseraceje by their solitary style, length-
