194 ARBORETUM ET FKUTICETUM BRITANNICUM. 
Orper XXV. LEGUMINA‘CE/#. 
Ord. Cuar. Calyx with 5 divisions, either partitions, teeth, or clefts, the odd 
one anterior to the axis of inflorescence. Fruit a legume. Seed with the 
radicle next the hilum, (Lind/.)— Trees and shrubs natives of every climate. 
Leaves alternate, stipulate, generally compound; deciduous, or soinetimes 
evergreen ; petiole tumid at the base. Stipules 2 at the base of the petiole, 
and 2 at the base of each leaflet. Pedicels usually articulated, with 2 bract- 
lets under the flower. 
The name of Legumindcez is applied to this extensive and truly natural 
order, on account of the seeds of all the species being produced in leguminous 
pods, bearing more or less resemblance to those of the common pea or bean ; 
and quite different from the siliquose pods of cruciferous plants. 
The ligneous species are trees and shrubs, for the most part deciduous; and 
they are disposed through almost every part of the world. The order contains 
some of our finest ornamental shrubs and low trees, such as Robinia, CYtisus, 
Wistaria, Genista, U‘lex, Amérpha, Halimodéndron, Acacia, Gleditschia, 
Cércis, and various others. It also contains some considerable trees, which 
belong to the genera Robinia, Gleditschia, Sophora, &c. The genera ‘con- 
taining hardy ligneous plants are in number twenty-three, which, after De 
Candolle and G. Don, we place in characterised sections, and ascribe to them 
short characters, that are more or less contradistinctive.
