The same order (_Scrophulariaceæ_) contains the handsome and favourite Foxglove (_Digitalis purpurea_), which grows abundantly in most dry woods and shady wastes, flowering from June to August. Its stout, unbranched stem varies from two to six feet in height, a large proportion being the axis of a long one-sided raceme of beautiful, drooping, purple or, occasionally, white flowers. The fruit is an ovate, pointed capsule that splits into two valves and contains many seeds. It is remarkable that this plant does not grow freely on chalk and limestone soils, yet it will often make a sudden appearance in great profusion as we pass over the edge of a calcareous district. The flower is shown on Plate II, Fig. 2. Of the order _Labiatæ_ we shall note one species only, and that is the pretty Wood Betony (_Stachys Betonica_), a very common plant in the woods and thickets of the south of Britain. It is a hairy species, with a slender, simple or slightly-branched stem from one to two feet high; and deeply-crenate, oblong leaves. The lower leaves have long stalks, and are heart-shaped at the base; but those of the stem are narrower, sessile or shortly stalked, tapering at the base. The flowers, which bloom from June to August, vary much in colour, ranging from a deep purple or crimson to a rose-pink or (rarely) white; and they form a dense oblong, terminal spike, consisting of whorls of six or more, with a bract at the base of each calyx, and a pair of sessile leaves just below the lowest whorl. The calyx is ribbed, with five very sharp teeth; and the corolla, which is much longer than the sepals, has an erect, oval, upper lip, and a spreading, three-lobed, lower lip. The stamens are in two pairs, immediately under the upper lip; and the fruit consists of four little rounded nuts. [Illustration: SLENDER FALSE BROME.] In the dry woods of South Britain we occasionally meet with the Wood Scorpion-grass or Wood Forget-me-not (_Myosotis sylvatica_), of the order _Boraginaceæ_. This plant is very much like the favourite Water Forget-me-not, and has equally large flowers, but it is much more hairy. Its stem is erect, without runners; and the blue flowers form a one-sided raceme without bracts. As the flowers expand the stalk lengthens considerably, with the result that the fruits are very distant. Among other features by which we may distinguish between the Wood Forget-me-not and the commoner Water Forget-me-not we may mention that the corolla of the former is flatter; and the calyx, cleft to its base into narrow segments, is very rounded below, and covered with stiff, hooked bristles. The plant flowers from June to August.
