Leguiminose—Sophora. 137 
The genus Hdwérdsia is usually incorporated with this. 
E. grandiflora or, as it should be here termed, Sophdra tetra- 
ptera, is a small tree or bush from New Zealand, very variable 
in size, foliage and flowers, the extreme forms having been de- 
scribed as distinct species. The leaflets are small, and usually 
very numerous, and the flowers conspicuous, bright yellow, in 
pendulous racemes. The pod is 4-winged, and constricted 
between the seeds. This requires a wall and extra protection 
in severe weather. 
Sun-Orver 11.—Ceegalpines. 
Calyx usually deeply partite. Petals imbricate, the upper 
one innermost. Stamens usually free. 
30. GLEDITSCHIA. 
Deciduous trees often furnished with simple or branched 
rigid spines. Leaves bipinnate, and on the same tree simply 
abruptly pinnate. Flowers polygamous, small, greenish or white, 
in axillary clustered racemes or fascicled cymes. Pod flattened, 
coriaceous or somewhat fleshy. There are four or five species, 
from North America and temperate and tropical Asia. So 
named in memory of a German botanist. 
1. G. triacdnthos. Honey Locust.—This is the species 
usually seen in England. It is a handsome tall-growing tree 
with a large spreading top. The stem and branches are usually 
armed with formidable trifid thorns; but the most remarkable 
feature is the long thin flat twisted pendent pods. In Autumn 
when these are numerous they give the tree a very curious 
appearance. The leaves are pinnate or bipinnate, and 
slightly hairy. A native of North America, and perfectly 
hardy in this country. We must not omit to mention that 
there is amongst others an unarmed variety, and also a pen- 
dulous one. 
2. G. monospérma, syn. G. imérnis. Water Locust.— 
Another handsome North American tree, readily distinguished 
from the foregoing by its 1-seeded pod, but otherwise scarcely 
differing from it. It is usually a smaller tree in all its parts, 
with less rigid thorns. 
G. Sinénsis, syn. G. horrida, is an eastern species of similar 
habit. There are several varieties of it, including an unarmed
