2. =Cercis siliquastrum= (EUROPEAN JUDAS-TREE.), from Europe, with
obtusely pointed, somewhat kidney-shaped leaves, and white to purple
flowers, is sometimes cultivated. It is not so tall or tree-like as the
American species.

Tall trees with alternate, very large (2 to 4 ft. long), unequally
twice-pinnate leaves. Flowers white, conspicuous, in racemes at the ends
of the branches. Fruit a large pea-like pod. Some trees are without

ovate, of a dull bluish-green color. Shoots cane-like, blunt and stubby,
quite erect. Bark exceedingly rough. Pod large, 6 to 10 in. long, 2 in.
broad, with seeds over 1/2 in. across. A large (50 to 80 ft. high) tree

1. =Gleditschia triacanthos=, L. (HONEY-LOCUST.) Leaflets
lanceolate-oblong, somewhat serrate. Pods linear, 1 to 1 1/2 ft. long,
often twisted, filled with sweet pulp between the seeds. A large,
handsome, clean tree, with usually many stout, much-branched thorns,
especially abundant on bruised portions of the trunk and large branches;
thorns compressed at base. Wild from Pennsylvania southward and
westward, and extensively cultivated throughout.

A variety without thorns is frequently met with (var. _inermis_), also
one with drooping foliage (var. _Bujotii pendula_).
