The flowers have five petals, and each petal has V-shaped notches cut in the outer edge. The lower part of the petals is hidden from sight in the calyx-cup. The five sepals which form this calyx-cup are joined together, and they are swollen like a bladder. This bladder is covered with a fine network of reddish veins, and has five teeth round its mouth. You will easily recognise the Common Bladder Campion by this curious calyx. In this white Bladder Campion the stamens and the seed-vessel are found in the same flower, and you can always see the forked tip of the seed-vessel, rising among the dark green heads of the stamens. The leaves of the Common Bladder Campion are smooth and shiny. They grow opposite each other in pairs, and wherever a pair joins the main stem, the stem is swollen like the joint of a finger. 3. SEA CAMPION The Sea Campion grows by the seashore, by the side of mountain streams, or on wet rocks among the hills. It blooms all summer, and although it is really a smaller plant than the Common White Campion, the flowers are larger. These flowers have five white petals, each with a V-shaped notch in the outer edge. Half way down these petals there is a white-fringed scale. These scales stand up like a crown round the inside of the flower. The calyx is swollen like a bladder, and is covered with fine veins, the same as in the Common Campion. Round the mouth it has five sharp teeth. In this plant the flowers do not grow in groups of two or three. Each flower appears singly at the end of a slender stalk, and there are several pairs of small leaves a good way below the flower. These leaves are slightly thick and juicy. They grow so close together on the ground that it looks as if it were covered with a green mat. PLATE XXVI: 1. COMMON EYEBRIGHT. 2. WHITE DEAD NETTLE. 3. SPOTTED ORCHIS. 1. COMMON EYEBRIGHT This humble little plant is to be found everywhere on heaths and meadows and pastures. It blooms plentifully in summer and autumn. The flowers of the Eyebright grow in clusters of four to six at the end of the main stem. They are white, or pale lilac streaked with pink, and they are small and unattractive. The petals are joined together into a tube, with two lips at the mouth. The upper lip has two divisions, and the lower lip is cut up into three. They appear to be five unequal petals standing round the mouth of the tube. Inside the tube are four purple-headed stamens, two long and two short. You can see them appearing at the mouth of the tube, also the slender white point which rises from the seed-vessel. The calyx is a green cup with four deeply pointed teeth at the mouth. The tube of the flower goes down into the cup, and the five unequal petals stand round its mouth. The Eyebright stem varies much in height. Sometimes you find it only about two inches from the ground, and in other places it has straggled eighteen inches high. These stems are very hairy.
