The five petals joined together form a bell, which is cut into deep teeth at the edge. Within this bell, there are five stamens clinging to the sides, and from the seed-vessel, a long, slender white thread rises. You can see this white thread best after the yellow bell is withered, and the seed-vessel is left sitting in the centre of the calyx. The green calyx-cup is very shallow, with fine, sharply pointed teeth round the mouth. The stem of the Comfrey is covered with hard, rough hairs. It has ridges running from top to bottom, and it is hollow in the middle. The leaves on the stem grow in tufts of three or four, without any stalks. They are narrow and pointed, with wavy edges, and are covered with hairs. Many other coarse leaves rise from the root. These leaves, too, have no stalks, and they are broad and hairy. 1. SNEEZEWORT YARROW This sturdy flower is the parent of the snow-white Bachelor's Buttons, which grow in our garden: it is a cousin of the Millfoil or Yarrow. It is common all over the country, where you find it in meadows and ditches, and by the roadside. It blooms in autumn. The flowers resemble small daisies. You find about a dozen growing together on short stalks, near the top of the main stem. Each daisy consists of a disc which is closely covered with greenish-white tube-flowers. The mouth of these tube-flowers is cut into points which bend outward, and coming out of the centre of each tube, you can see the yellow tip of the seed-vessel, round which the heads of the stamens are placed edge to edge like a deep collar. Round the outer edge of the disc there is a small circle of tube-flowers, each of which has a broad white strap, and these straps are nicked at the ends. Underneath these small daisies stands a circle of tiny green pointed leaves; these form a cup which protects the plant when it is in bud. The stem of the Sneezewort is very sturdy. The leaves are sword-shaped, with long veins running from the base to the tip. They clasp the stem, and all round the edge they are cut into very fine teeth, like a saw. 2. MOUNTAIN EVERLASTING This woolly little plant is common over most of the north country, on heaths and sandy pastures and in upland districts; but you do not find it in the south of England. It is in flower all summer. The root of the Mountain Everlasting is like a thin brown worm lying on the surface of the ground, and from this root, long, slender brown threads go down into the ground and keep the flower steady. The flowers resemble small woolly daisies. They grow in clusters of four or more, at the end of the main stem, and each cluster has a short, stiff stalk of its own. These woolly daisies are made up of a great many tiny pink flower-tubes, each with a ring of fine white hairs round it. These tubes are surrounded by a double row of woolly, downy leaves which stand out like the strap-shaped rays of the daisy.
