wings the largest. There are ten stamens, free, and of unequal length. The legume is oblong and many-seeded; and it opens only on the dorsal suture, the other side to which the seeds are attached being slightly winged. The flowers are each on a separate flower-stalk or pedicel, but they rise from the trunk and branches in tufts or fascicles. The leaves are simple and cordate; and they do not appear till the flowers have faded. [Illustration: FIG. 19.—FLOWERS OF THE KENTUCKY COFFEE-TREE.] The Kentucky Coffee-tree (_Gymnocladus canadensis_) is the last plant belonging to this division that I shall attempt to describe. This tree is called in Canada, Chicot, or the stump-tree, from its having no visible buds, and thus appearing like a dead stump in winter. The flowers of this plant are white, and they are produced in racemes, but they bear no resemblance to the pea flowers, having rather a star-like appearance, like those of the Jasmine (see _fig._ 19). The calyx (_a_) is tubular; and the upper part or limb is divided into five parts (_b_), which alternate with the petals of the corolla (_c_). There are ten stamens, but they are completely enclosed in the tube of the calyx. The pod is very large, the valves becoming hard and bony when dry; and the seeds are like large beans, the pod being deeply indented between the seeds. The leaves are bi-pinnate, with from four to seven pairs of pinnæ; the lower having only one small leaflet, but the rest bearing from six to eight pairs of leaflets each. This tree must not be confounded with the true Coffee-tree, which belongs to Rubiaceæ, and from which it is perfectly distinct in every respect; and it only takes its American name from its beans having been used as a substitute for coffee. The outer bark of this tree, when it becomes old, splits off in narrow strips and rolls up; and its timber, like that of the Robinia or False Acacia, having very little sap wood, is thus very strong in quite young trees, though it is of little value when the tree is full-grown. The species contained in the first and second divisions of this order will be easily recognised by botanical students; and though those of the third division are much more difficult to find out, still there is a kind of family likeness, particularly in the leaves, which will enable the eye, with a little practice, to recognise them. The student should visit the hothouses of botanic gardens and nurseries, and should there endeavour to pick out plants belonging to this order. CHAPTER III.
