In very dense woods, where the light is so much reduced that but few flowers will grow, we may generally find the Wood Sanicle (_Sanicula europæa_), a smooth umbelliferous plant with a short, hard rootstock, and a simple stem from one to two feet high. The leaves, which are all radical, are on long stalks, and are palmately divided into three or five shining lobes that are themselves cut and sharply toothed. The flowers are sessile, in little rounded heads; the whole inflorescence forming an irregular umbel or a loose panicle. They are very minute, of a pinkish white colour; and the outer ones of each head usually have no pistil. They bloom during June and July, and are followed later by little prickly fruits about a sixth of an inch long. [Illustration: THE ALEXANDERS.] In damp woods we commonly meet with the tall, stout, branching Angelica (_Angelica sylvestris_) of the same order (_Umbelliferæ_), with a thick, furrowed stem, two to four feet high, downy above, and usually more or less shaded with purple. Its lower leaves are very large, with stalked, ovate leaflets, from one to two inches long, often three-lobed, and always sharply toothed. The upper leaves are much smaller, with fewer leaflets, and often consist only of a broad sheath with a few small leaflets at its summit. The flowers are white, generally tinged with pink, and form a large terminal umbel of from sixteen to forty rays, with two or three narrow primary bracts, and several fine secondary ones. They bloom during July and August, and are succeeded by flattened fruits with three ribs on the back of each of the two carpels. The carpels are also broadly winged; and, as the wings do not adhere, each fruit is surrounded by a double wing. [Illustration: THE ELDER.] The order _Caprifoliaceæ_ includes the Common Elder (_Sambucus nigra_), the white or cream-coloured flowers of which are so conspicuous in our woods and hedgerows in June. This tree grows to a height of fifteen or twenty feet, and its young branches are remarkable for the large quantity of pith they contain. The general form of the leaves and the arrangement of the flowers are seen in our illustration. Each flower has a calyx with five small teeth; a corolla with a short tube and five spreading limbs; five stamens attached to the base of the corolla; and an inferior ovary. The fruit is a black, berry-like drupe containing (usually) eight little, seedlike stones. [Illustration: THE GUELDER ROSE.]
