The order _Rosaceæ_ contains the Great Burnet (_Sanguisorba officinalis_), the only British representative of its genus. It is very much like the Lesser Burnet (p. 301) in general appearance, but much taller and larger. It is a smooth plant, with an erect stem from one to two feet high, the upper part of which is almost leafless. The leaves are mostly radical or on the lower part of the stem, and are pinnate, with from seven to thirteen oval or oblong, toothed leaflets. The long peduncles each bear an oval head of crowded flowers of a dark purple colour. Each flower has a calyx of four coloured lobes, enclosed within bracts; and four stamens. There are no petals. The plant is moderately common in the damp meadows of England and South Scotland, and flowers from June to August. The Lady's Mantle (_Alchemilla vulgaris_) is a common plant in the hilly pastures of North England, but is much less frequent in the South. It varies from six to eighteen inches in height, and bears loose, terminal clusters of small yellowish-green flowers from June to August. The little flowers have a free calyx of eight segments in two whorls of four, the outer ones smaller than the inner; no petals; a few stamens; and an ovary of one or two one-seeded carpels enclosed in the tube of the calyx. In moist meadows and other damp places we commonly see the fragrant Meadow Sweet or Queen of the Meadows (_Spiræa Ulmaria_), of the same order. This is an erect plant, from two to four feet high, bearing densely-crowded cymes of small, creamy-white flowers from June to August. Its stem is rather thick, often reddish in colour; and the leaves are large, pinnate, with from five to nine ovate, irregularly-toothed leaflets, two or three inches long, and also several smaller leaflets at the base of the stalk or between the larger ones. Each of the little flowers has a five-lobed, free calyx; five petals; numerous stamens; and an ovary that ripens into from five to eight little twisted capsules. [Illustration: THE MEADOW SWEET.] The Burnet Saxifrage (_Pimpinella Saxifraga_), of the order _Umbelliferæ_, is a common plant in dry pastures, and is very generally distributed. Its stem is from one to two feet high, and but little branched; and the leaves are very variable in form--the radical ones usually pinnate, with from three to nine oval or round leaflets that are either lobed or deeply toothed; and the upper also pinnate, with the segments of the leaflets few and very narrow. The umbels are terminal, with from eight to sixteen slender rays, and no bracts. The flowers are small and white, and appear from July to September.
