spines on the branches: the petioles are spinescent: the leaflets com- 

 monly two pairs, but sometimes three and even four, linear-lanceo- 

 late, mucronate at the end with a spinulc, opposite and remote: the 

 peduncles are so short that the flowers seem to be sessile. It is a 

 native of Siberia. 



On account of the length and toughness of the branches, and its 

 large stout thorns, it is admirably adapted to form impenetrable 

 hedges, and is sufficiently hardy to bear our climate. 



The seventh is an upright tree without thorns, growing to the 

 height of twelve feet: the leaves alternate, numerous, shining; having 

 three leaflets on each side, sometimes two, very seldom five; these 

 are ovate, blunt, emargiuate, entire, petioled, opposite, two inches 

 long: the racemes axillary, half a foot in length; pedicels short, 

 two-flowered, numerous: the flowers have the smell and colour of 

 violets. It is a native of Carthagena. 



The eighth species has a shrubby stem, three feet high, upright, 

 branched : the leaflets ovate-lanceolate, smooth, bright green, two or 

 three- paired: the racemes terminating, short: the corolla yellow: 

 the legume oblong, narrowing to each end, smooth: the branches 

 round, unarmed: the leaflets five, ovate, smooth, quite entire: the 

 racemes have three flowers fixed at each tooth, each on its proper 

 pedicel : the calyx subtruncate. It is a native of the East Indies, &c. 

 Culture. The first six hardy sorts are all capable of being paised 

 from seeds, cuttings, layers, and suckers; but the seed method is 

 said to afford the best plants. 



The seeds should be sown about the end of March or beginning 

 of the following month, on a bed of light mould, being covered to 

 the depth of half an inch. In the first sort and varieties the plants 

 mostly appear in the course of six or eight weeks; but in the other 

 kinds often not till the next spring. They should be well weeded and 

 watered, and when sufficiently strong be set out in the spring or 

 autumn in nursery-rows, for two or three years, in order to remain 

 to have proper growth for final planting out. 



The cutlings should be made from the young shoots, and planted 

 out in the beginning of autumn, in a shady border where the soil is
