Passing now to the order _Leguminosæ_ we note first the Dyer's Green-weed (_Genista tinctoria_)--a shrubby plant, common in the thickets and bushy places of South Britain, flowering from July to September. The stem is woody and stiff, but green; its base rests on the ground, but it sends up erect flowering branches from one to two feet high. The yellow flowers are arranged in terminal racemes, each flower having a lanceolate bract at the base of its short stalk, and very small bracts at the base of the calyx. The calyx has five teeth, the three lower ones much narrower than the other two, all terminating in a sharp point; the corolla is much longer than the calyx, with an oblong standard or upper petal; the stamens are all united by their filaments, forming a complete sheath round the ovary; and the pods are smooth, about an inch long, and compressed. In the thickets of most parts of Britain, but more especially those of the eastern counties, we may often meet with the Sweet Milk Vetch (_Astragalus glycyphyllos_) of the same order. It is a prostrate plant, with pale yellow or cream-coloured flowers that bloom from June to August. The flowers are about half an inch long, in short, dense, shortly-stalked racemes. The calyx has five teeth; the upper stamen is free from the other nine, which form a divided sheath round the ovary; and the pod is smooth, round, curved, over an inch long, and divided by a double membrane into two cells, each of which contains about seven seeds. [Illustration: THE WILD RASPBERRY.] In the same order are two species of Everlasting Pea (_Lathyrus_), both of which grow in thickets and other bushy places. One is the Tuberous Everlasting Pea or Tuberous Bitter Vetch (_L. macrorrhizus_), an erect plant, from six inches to a foot in height, flowering from May to July. Its rootstock has small tubers, and the stem is winged. The leaves are pinnate, with from two to four pairs of narrow leaflets and half arrow-shaped stipules; they have no tendrils, but the leafstalk terminates in a fine point. The flowers are of a red-purple colour, changing to greenish blue as they fade; and are in loose racemes of from two to four. The other is the Narrow-leaved Everlasting Pea (_L. sylvestris_), a straggling plant, from two to six feet long, flowering from June to August. It is not so common as the last, but may be found in similar situations. Its stem has very narrow wings; and the leaves have very narrow leaflets, flattened stalks, branched tendrils, and half arrow-shaped stipules. The flowers are rather large, of a pale purple colour, with a greenish keel, and a green spot on the large upper petal. They are arranged in loose racemes. [Illustration: THE ROSE BAY WILLOW HERB.]
