dosely aniK'ct with sniall brown prickles, or ra- 

 ther stifl" bristly I'.airs, like raspljcrries and some 

 SOI ts of roses : the leaves ar^- like those of the 

 first sort, but the leaflets are larger and rounder : 

 ■the Ho\\trs arc larger, and of a deep nwe co- 

 lour, but ihey have no scent: they come out 

 early in June, and make a fine appearance ; 

 each flovscr is on a short separate pedicel ; the 

 leoumes flat oblong. It is a native of Carolina. 



The third has arboreous trmiks, commonly 

 branched from the bottom, slejider, with a 

 smooth, shining, coriaceous bark, covered by a 

 arcenish asii-coloured skin : branches alternate, 

 very nnicli divided ; twigs rod-like, weak, very 

 leafy, ash-coloured or greenisli, with longitu- 

 dinal nerves running from bud to bud : buds al- 

 tc'rnate, frequent, bearing both leaves and flow- 

 ers, unarmed, with the stipules of the bud- 

 leaves soft, but in the new branches spinesccnt, 

 divaricating, riiL'id. It is a native of Siberia, 

 flow cring in April and May. 



The fourth species has a branched trunk frotn 

 the bottom, with a dusky or greeni?h-asli-co- 

 loured baik ; there are commonly many lateral 

 shoots or 'iuckers from the root : the branches 

 rod-lil;c, pliant, loaded with leaves and flowers, 

 of a shining yellowish colour, with longitudinal 

 gray nerves, u lt!i irijile spii:es : the leaves on 

 the shoots of tiie year alternate, with spinescent 

 stipules; from the buds in bundles, with un- 

 armed stipules : the leaflets clustered, obovate, 

 attenuated at the base, with a. spinulc at the 

 end : petiole spinescent, after the leaves are 

 fallen, hardening with the stipules into a triple 

 spine : the peduncles on the braiTches of the pre- 

 ceding year from each bud, one, two, or three, 

 bent a little at the joint, one-flowered. It is a 

 native of Siberia, by the Volga, &c. 



The. fifth has trunks covered with a shining 

 yellowish hark : wood of a Very deep bay, almost 

 as hird as horn : the older twigs round, with 

 -a beautifully golden shining cuticle ; branchlets 

 gray, with very frequent two-spined buds : the 

 spinules slender like needles, spreading, arising 

 from the stipules, in the older branches decidu- 

 ous : the leaflets four or six in the spontaneous 

 shrub clustered in bundles, quite sessile, linear 

 acuminate, a little hispid : the peduncles spring- 

 ing singly froiTi most of the buds on the branch- 

 lets among the leaves, the length of the leaflets, 

 bent at the joint. In this climate it is a low 

 shrub, seldom rising more than three feet. The 

 flowers are yellow, and appear in April. It is a 

 native of Siberia. 



The sixth species resembles the third sort, but 

 is distinguished by its stiff or thorny stipules: 

 3t is a shrub above the height of a man : tlie leaf- 

 lets six or eight, ovate, even : common petiole

woody, the wiiole of it peremrud, thorny at,.tbc 

 end: the stipules awl shaped, thorny, perijn- 

 nial : the trunk is scarcely an inch and half in 

 diameter, with branches oi'ten a faihom in le.ngth, 

 subdivided, twisted and dilfused, so. as to form 

 a hemispherical head, full of branches antl 

 thorns. Being covered with fiower.-; during the 

 whole summer, it appears verv beaiitifu! : the 

 wood bay-coloured within, on ' the outside yel- 

 low, and very hard : the cuticle on. the younger 

 branches gieenish yellow, less shining, and 

 more strigose than in the fifth sort, with a;;h- 

 coloured longitudinal nerves, running from 

 branch to branch : the branches are rc\md, di- 

 varicating, alternate : the thorns spreading out 

 every way almost at right anales, alterna'e, very 

 large, arising from the pi^rmanent petioles en- 

 lariied, marked also with the scars of the leaf- 

 lets, and having at the base on each side a small, 

 bristle-shaped s])inu!e, standing up, and arising 

 from the stipules : there are several leaves and 

 two or three flowers from the axils of all the 

 spines on the branches : the petioles are spines- 

 cent : the leaflets commonly two pairs, but 

 sometimes three and even four, linear-lanceo- 

 late, mucronate at the end with a spiiiulc, op- 

 posite 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 lar-ge 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 leaf- 

 lets on each side, sometimes two, very seldom 

 five ; these are ovate, blunt, emarginate, entire, 

 petioled, opposite, two inches long : the ra- 

 cemes axillary, half a foot in length; pedicels 

 short, two-flowered, numerous : the flowers 

 have the smell and colour of violets. It is a na- 

 tive of Carthagena. 



The eighth species has a shrubby stem, three 

 feet high, upright, branched : the leaflets ovate- 

 lanceofate, 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, un- 

 armed : the leaflets five, ovate, smooth, quite 

 entire : the racemes have three flow ers fixed at 

 each tooth, eacli on its proper pedicel : the calyx 

 subtruncate. It is a native of the East Indies, 

 &c. 



Culture. — The first six hardy sorts are all ca- 

 pable of being raised from seeds, cuttings, layers, 

 and suckers ; but the seed method is said to af- 

 ford the best plants.
