THE BUDS

“Let us take a branch of lilac or any shrub. In the angle formed by each leaf and the branch that bears it, an angle called the axil of the leaf, we shall see a little round body enveloped in brown scales. That is a bud or, as it is also named, an eye.

“Buds make their appearance at fixed points, and it is the rule for one to form in the axil of each leaf; it is also the rule for the tip-end of the branch to bear one. Those situated in the axils of the leaves are called axillary buds, and those that are found on the ends of branches, terminal buds. They are not all equally vigorous, the strongest being at the top of the branch, the weakest at the bottom. The lower leaves even shelter such small ones in their axils that only the closest scrutiny will reveal them. These diminutive buds often perish without developing unless artificially encouraged to do so. On a lilac branch it is easy to note these differences of size from bud to bud.

“Both terminal and axillary buds are divided into two classes. In developing some sprout up and produce only leaves; these are called leaf buds. When fully developed they become shoots or scions, and [81]finally branches. Others push upward but little and bear only flowers or leaves and flowers simultaneously. They are called flower buds, or simply buds. It is very easy to distinguish one kind from the other on our fruit-trees, the leaf buds being long and pointed, the flower buds round and thicker.

“All summer long the leaf buds grow in the axils of the leaves; they are gaining strength to go through the winter. Cold weather comes and the leaves fall, but the buds remain in their place, firmly implanted on a ledge of the bark, or a sort of little cushion, situated just above the scar left by the falling of the adjacent leaf. To withstand the rigors of cold and dampness, which would be fatal to them, winter clothing is indispensable. It consists of a warm inner envelope of flock and down, and a strong outer casing of well varnished scales. Let us examine for instance the bud of a chestnut-tree. Within we shall find a sort of wadding enswathing its delicate little leaves, while on the outside a solid cuirass of scales, arranged with the regularity of tiles on a roof, wraps it closely. Furthermore, to keep out all dampness, the separate pieces of this scale armor are coated with a resinous cement which now resembles dried varnish, but softens in the spring to let the bud open. Then the scales, no longer stuck together, separate, all sticky, and the first leaves unfold covered with a velvety red down. Nearly all buds, at the time of their spring travail, present in different degrees this stickiness resulting from the softening of their resinous coating. I will mention [82]especially the buds of the ash, alder, and, above all, the poplar, which when pressed between the fingers emit an abundant yellow glue, of bitter taste. This substance is diligently gathered by the bees, which use it to make their bee-glue, that is to say the cement with which they stop the fissures and rough-coat the walls of their hive before constructing the combs. Under its modest appearance the bud is a veritable masterpiece: its varnish excludes dampness; its scales protect it from harmful atmospheric influences; its lining of flock, wadding, downy red hair, keeps out the cold.

“The scales form the most important part of the bud’s winter clothing. They are nothing more nor less than tiny leaves hardened and toughened, in short so modified as to serve the purpose of protection. The leaves immediately under them and constituting the heart of the bud have the usual form. They are all small, pale, delicate, and arranged in a marvelously methodical manner so as to take up the least possible room and at the same time to be contained, all of them, despite their considerable number, within the narrow limits of their cradle. It is surprising what a quantity of material a bud can make room for under its sheath of scales in a space so small that we should find it difficult to pack away there a single hemp-seed; and yet it holds leaves by the dozen or a whole bunch of flowers. The bunch enclosed in a lilac bud numbers a hundred and more blossoms. And all this is contained in that narrow cell, with no tearing or bruising of any [83]portion of it. If the various parts of a bud were disconnected, one by one, if the delicate arrangement were once undone, what fingers would be clever enough to put it together again? The principal leaves lend themselves to a thousand different modes of arrangement in order to occupy the least space possible. They take in the bud the form of a cornet; or they roll themselves up in a scroll, sometimes from one edge only, sometimes from both; or they fold up lengthwise or crosswise; or they may roll up into little balls, or crumple up, or fold like a fan.”
