The last family of the Coniferæ is the Cupressinæ, so named after the great and beautiful cypress tree, which is said to have given its name to the island of Cyprus, which in turn gives its name to cupreous metal, or copper. The cypress tree similarly gives its name to "coffers" and "coffins" made of its wood, as the Buxus or box-tree has given its name to a "box." The cypress is the Gopher tree of the Hebrews. The family includes many species of junipers (Juniperus) and the American and Japanese Arbor vitæ (Thuya) and its allies. In the common cypress (Cupressus sempervirens) the leaves are singular, small, scale-like growths, which are flattened on to the delicate branchlets which bear them. In other trees of the family both such leaves and also upstanding lancet-like leaves are present. The main character is the small size and globular shape of the cones and the very few swollen scales, more like solid wedges adherent to one another, which build them up. These wedge-like scales are not arranged in whorls, but are opposite to one another on the short axis or stem of the cone. The common juniper (Juniperus communis), the _génévrier_ of the French, grows abundantly on the chalk downs of the South of England, where it appears as a small bush, not exceeding 5 feet in height, but in favourable conditions reaches a height of 20 feet. The cones of the juniper are numerous, and each consists of only three ovuliferous scales, and is only one-fifth of an inch in diameter when ripe, and of a blackish violet colour. At the close of this compressed survey of the order Coniferæ, let me put the chief forms and groups at which we have looked in a tabular form, thus: =Order CONIFERÆ:= _FAMILY_ 1.--ABIETINÆ.
