The leaves are long and narrow, and they have little hooks along the edge. They grow in a circle of eight round the square stem, with a short space between each circle. You will notice that the stalks which bear the tiny white flowers spring from the same part of the main stem as the leaf circles. 2. WOODRUFF The sweet-smelling Woodruff is common all over the country, and when dried its perfume is like new-mown hay. It grows in woods and on shady hedge-banks, and it flowers in early summer. The flowers are small and white, with four petals which stand round the mouth of a tiny tube. Inside this tube are four yellow-headed stamens, and there is a small green sepal-cup in which the white tube stands. The flowers grow in clusters at the end of the main stem. They do not rise from each circle of leaves as in the Goosegrass. The tiny seeds are black, and each seed is thickly covered with soft bristles, which are hooked at the end. The ridged stem of the Woodruff is often a dull red colour. This stem is very feeble, so the Woodruff is usually found lying in a tangle along the ground. It has not so many hooks as the Goosegrass with which to catch hold of other plants, and so raise itself. The leaves grow about an inch apart on the stem, in beautiful circles. In each circle there are eight narrow leaves which are pointed at the end. The circles nearest the foot of the stem lie flat open like a rosette, but those that are further up are usually half closed, with all their points standing upwards. 3. YARROW OR MILLFOIL The Yarrow or Millfoil is a very common plant all over Britain. It grows on waste ground and in the corners of fields, and it is in flower in late summer and autumn. It is one of the daisy plants, and you must look at it carefully. The flowers grow in clusters, three or four together, at the end of stalks which branch from the main stem. They are white, and look like tiny daisies. You must pick one of them gently to pieces, and then you will find that each daisy is really made up of a great many small flowers crowded together on a disc. The outer flowers consist of a white tube, with one long white strap, and there is a row of these white straps standing out like a frill round the yellow centre. Inside this white border there are a great many tiny yellow tube flowers, with five points at the mouth of each tube, but these you will not see without a microscope. Outside this mass of flowers grows a ring of small green leaves, which are closely packed together and are very woolly. The stem of the Yarrow is stiff and smooth and is slightly tinged with red. The leaves are long and narrow, and each leaf is made up of many tiny pairs of leaflets placed opposite each other on the stem. Each leaflet is cut up into many divisions, so that the whole leaf is light and feathery like a small fern. PLATE XXII: 1. OX-EYE DAISY 2. DAISY 3. SCENTLESS MAYWEED 1. OX-EYE DAISY
