The Corn Bellflower or Wild Venus's Looking-glass (_Campanula hybrida_), of the order _Campanulaceæ_, is not uncommon in the cornfields of the chalky districts of South and East England. It is an erect plant, from six to ten inches high, bearing purple, blue, or (occasionally) white flowers from July to September. In addition to the general features shown in our illustration we may note that its long, inferior ovary is three-angled; and that the fruit splits, when ripe, by the formation of slits near the top. In the order _Boraginaceæ_ we have the Small Bugloss (_Lycopsis arvensis_), a branched plant, from six inches to two feet in height, covered all over with stiff bristles that are swollen at the base. Its leaves are oblong or very narrow, wavy, and sometimes toothed; the upper ones sessile and often clasping the stem; and the lower frequently shortly stalked. The flowers are small, pale blue, in simple or branched, one-sided spikes. They have a deeply-cleft calyx of five segments; and the species may be distinguished from other, somewhat similar plants of the same order by the form of the tube of the corolla, which is always bent in the middle. This plant is very common in the corn fields of most parts; and flowers during June and July. [Illustration: THE DWARF SPURGE.] Our next flower is the pretty little Scarlet Pimpernel or Poor Man's Weather Glass (_Anagallis arvensis_) of the Primrose order (_Primulaceæ_), which is very common in cornfields and on other cultivated ground, flowering from May to very late in the autumn. The stem of this plant is procumbent and much branched, the branches sometimes reaching a length of considerably more than a foot; and its leaves are opposite, sessile, broadly ovate, undivided, and dotted beneath. The little flowers are solitary in the axils of the leaves, on long, slender peduncles that are always curved backwards as the fruits ripen. The calyx is deeply cleft into five pointed segments; and the bright scarlet (occasionally pink or white) corolla, fringed with minute hairs, spreads its five lobes only in sunny weather. The fruit is a little globular capsule, enclosed in the persistent calyx, splitting transversely into two hemispheres when ripe.
