while, and smelling very sweet: they appear in June, and when the 

 trees are full of flower, make a fine appearance and perfume the air 

 round them; but they seldom continue more than a week. Jtisa 

 native of North America, where it grows to a very large size, and 

 the wood is much valued for its duration. 



There is a variety which has no thorns on the branches, but 

 which is easily known at first sight by its peculiar appearance. 



And the Echinated, or Prickly-podded American False Acacia, 

 in which the pods are much shorter, and closely beset with short 

 prickles, but in other respects agrees with the common sort. 



The second species rises in its native situation sometimes to the 

 height of twenty feet, but in this climate seems to be of low growth; 

 the branches spread out near the ground, and produce their flowers 

 very young; the young branches, and also the peduncles and 

 calyxes, are closely armed with small brown prickles, or rather stiff 

 bristly hairs, like raspberries and some sorts of roses : the leaves are 

 like those of the first sort, but the leaflets are larger and rounder: 

 the flowers are larger and of a deep rose colour, but they have no 

 scent: they come out early in June, and make a fine appearance ; 

 each flower is on a short separate pedicel: the legumes flat oblong. 

 It is a native of Carolina. 



The third has arboreous trunks, commonly branched from the 

 bottom, slender, with a smooth, shining, coriaceous bark, covered 

 by a greenish ash-coloured skin: branches alternate, very much 

 divided; twigs rod-like, weak, very leafy, ash-coloured or greenish, 

 with longitudinal nerves running from bud to bud: buds alternate, 

 frequent, bearing both leaves and flowers, unarmed, with the stipules 

 of the bud-leaves soft, but in the new branches spinescent, divarica- 

 ting, rigid. It is a native of Siberia, flowering in April and May. 



The fourth species has a branched trunk from the bottom, with a 

 dusky or greenish-ash-coloured bark; there are commonly many 

 lateral shoots or suckers from the root': the branches rod-like, pliant, 

 loaded with leaves and flowers, of a shining yellowish colour, with 

 longitudinal gray nerves, with triple spines: the leaves on the shoots 

 of the year alternate, with spinescent stipules; from the buds in.
