THE YEW1. Yew Tree2. Leaf Spray3. Stamen Flower4. Seed Flower5. Spray with Fruit
In history books we read how important the Yew tree once was. Long before the invention of guns and gunpowder, many of our soldiers carried bows made of Yew tree wood, and from these they shot deadly arrows with tremendous force. Three of England’s Kings—Harold, William Rufus, and Richard Cœur de Lion—were slain by such arrows, and it was from a Yew tree bow that Tell sent the arrow that halved the apple placed on his son’s head.
The Yew tree (1) grows very, very slowly; it never becomes a tall tree, not even when it has lived hundreds and hundreds of years, because, instead of sending up one thick trunk, it has thestrange habit of dividing into a cluster of trunks, three or four or more of equal thickness, which rise from one root. These trunks are covered with browny red bark and are very smooth; the red bark peels off in thin flakes, and you can see that the wood beneath it is a deep orange red.
From the clustered trunks many branches stretch out to form a densely bushy tree; these branches are closely covered with small twigs, on which grow short narrow leaves (2), ending in blunt points, and with the edges slightly curved backwards. These leaves grow alternately all round the twig, and they are dark and glossy above but much paler beneath. They do not fall from the tree in winter, as the Yew, like the Holly, is one of our evergreen trees. Yew tree leaves are very poisonous, and many tales are told of cattle and horses which have died from eating them.
Some people believe that the Yew tree is planted in churchyards because it is poisonous and is associated with death; while others think just the opposite, and say that it is placed among the tombstones to remind us that the soul is undying, like the Yew tree leaves.
In February or March if you strike a Yew tree bough with a stick you will see clouds of fine yellow powder rising from the tree. This powder is the stamen dust, and if you pull a spray of leaves and examine it you will discover clustersof small oval yellow flowers (3) nestling close to the main stem where the leaf joins it. The Yew tree belongs to the great family of trees whose fruit is a cone and which bear their flowers in catkins. Take a magnifying-glass, and it will show you that each catkin is composed of a bunch of stamens rising from a slender pillar at the foot of which are a few dry, papery scales. Each stamen has six dust-bags at the end, and when the stamen powder is ripe these dust-bags open, and the fine yellow powder is blown like meal over the leaves and seeds.
The Yew tree has seed flowers (4) as well as those which bear the stamens. Usually they grow on a different tree, but occasionally you will find them on the same Yew, but on a separate branch. It is a curious thing about the Yew tree and its relations that these seeds are not covered in any way, but lie naked to the sun and rain. They always grow on the under-side of the stem, and at first they look like tiny acorns. You notice a small disc surrounded by a few scales, and on this disc sits the little green acorn with its olive green skin. This acorn is waiting for the stamen dust to reach it. As soon as the wind has blown the yellow powder over it a beautiful cup of pale pink wax grows round the green seed. There is no hard, woody cone on the Yew tree; the fruit (5) is this palepink waxen berry, shaped like a fairy cup and filled with sticky juice. The walls of the pink cup are soft and fleshy, and you can just see the tip of the green seed standing up in the centre. They are very lovely, these waxy pink berries on the dark green spray, but they are said to be poisonous.
Sometimes at the end of a Yew spray there grows a curious-looking cone like a small artichoke, made of soft green leaves. This is caused by a tiny gnat which lays its eggs in a Yew tree bud, and in some strange way that we do not understand causes it to develop this tuft of strange leaves. You will remember that in the Oak a similar growth is found.
The wood of the Yew tree is very hard and durable, as are all woods which grow slowly. “A Yew tree post will outlast a post of iron” is a saying often repeated by farmers; but the Yew wood is not much in demand for manufacturing purposes.
