The four largest petals are so deeply cut round the edge that they appear to be fringed. But there are two long thin ones which are each in one piece. These petals are all joined together at the bottom, with the bunch of fluffy stamens and the seed-vessel inside. Behind this little ball there are six thin green sepals. These are very narrow and pointed, and they stand round the flower like the legs of a spider. The leaves are dark green, and they are very much lighter underneath than above. They are very narrow, with crinkled edges, and the upper half of the leaf branches into three or four parts, like a stag's horn. 2. COMMON DANDELION The Dandelion is as well known as the Buttercup and Daisy. It grows in all kinds of places, and it is in flower from early spring to late autumn. The large yellow flower-heads are made up of a great many separate little flower-tubes, which widen out at the mouth into a long yellow strap. These yellow tubes are placed on a round disc with the straps standing out in a circle, like a rosette. Each flower-head grows singly at the end of a long green stalk. The stalks are hollow, and when you break them a white milky juice oozes out. At the top of the stalk you find a cup made up of narrow pointed green leaves. Some of these leaves curve back over the top of the stalk. When the yellow flowers are withered, the round disc is covered with the tiny seed-vessels. Each seed-vessel ends in a slender green spike which has a beautiful tuft of starry down at its tip. This ball of starry down is one of the most beautiful things in the flower world. The leaves of the Dandelion are a smooth glossy green. They are shaped like a blunt arrow-head, and they have a white line running up the centre. The edges are cut up into huge teeth which are said to resemble the teeth of a lion. From this the plant gets its name. 3. TANSY The Tansy is to be found in hedge-banks, and by the roadside, or on the borders of the fields in many places all over the country, though in the North it is not very common. It flowers in autumn, and is a tall, bushy plant, with large green, ferny leaves. The Tansy has a short, green stem rising stiff and straight from the ground, and this stem branches at the top into three or four forks. Each of these forks divides again into two or three smaller forks, and there is a flower which looks like a yellow button at the end of each fork. If you pick one of these yellow buttons to pieces you find that it is made up of a great many yellow tubes, with a swollen green part at the bottom. These yellow tubes are of two kinds. In some the mouth of the tube is cut evenly all round into small scollops, and in others there is a yellow strap at one side of the tube. These tubes stand on a round disc, and at the back of this disc there is a thick double row of small green pointed leaves, which form a green cup behind the yellow buttons.
