The flowers of the Holly, though small, are conspicuous by their great number and white colour. They are about a quarter of an inch across, with four petals and four stamens or stigmas. Sometimes flowers with stamens are produced by the same tree that bears flowers with stigmas; but often the male and the female flowers are borne by separate trees, so that the possessor of a Holly that is solely male is sometimes puzzled by the fact that his tree, though covered with blossom, never produces a berry. The fruit is analogous in structure to that of the Plum and Cherry, and is technically termed a _drupe_; but instead of the single stone of these fruits, in the Holly-berry there are four bony little stones, each with its contained seed. The berries ripen about September, and are then scarlet and glossy, though here and there one finds a tree whose fruit never gets beyond the yellow stage of coloration. [Illustration: _Pl. 83._ Fruits of Holly.] [Illustration: _Pl. 84._ Bole of Holly.] Most parts of the tree have had their uses in medicine; the leaves, for example, being said to have value as a febrifuge, and the berries as a purgative, or in large doses (6 to 8) as an emetic. The smooth bark of large Hollies is often attacked by one of the most striking of our native lichens--_Graphis elegans_--whose black fruiting portions look like a raised cuneiform inscription. The Holly is not greatly subject to the attacks of insects, but many of its leaves will be found to have been tunnelled between the upper and lower skins by the larva of a minute moth, one of the Leaf-miners. It also provides the pabulum for the caterpillar of the Holly-blue butterfly (_Lycaena argiolus_). The dead leaves may be examined for the minute Prickly Snail (_Helix aculeata_). The wood of the Holly has an exceedingly fine grain, due to its slow growth, and it is very hard and white. These qualities make it valuable for many purposes, often as a substitute for Box-wood, and, when dyed black, in lieu of Ebony. * * * * * [Illustration: _Pl. 85._ Spindle--winter.] The Spindle-tree (_Euonymus europaeus_). The Spindle is right on the borderland between trees and shrubs, for though it will grow into a tree twenty feet high, yet our hedgerow specimens are usually bushlike, and only ten or twelve feet high. Until the autumn the Spindle, we fear, is rarely recognized as such, but gets confused with Buckthorn and Dogwood. In October, however, its quaint fruits have changed to a pale crimson hue, which renders them the most conspicuous feature of a hedgerow--even of one plentifully decorated with scarlet hips and haws and bryony-berries. The unusual tint of the Spindle, and the fact that it swings on a slender stalk, at once mark it out from the rigid-stalked hips and haws.
