Description
It is a large to very large tree, ranging up to 65–70 metres (213–230 ft) tall and 3–4 metres (9.8–13 ft) in trunk diameter, exceptionally even larger. Trees growing in the open may have a crown that reaches the ground, whereas trees densely spaced together will only exhibit a crown at the top, where light can reach the leaves. It is long-lived; some individuals can live well over a thousand years, with the oldest verified being 1,460 years.
The foliage forms flat sprays with scale-like leaves in opposite pairs, with successive pairs at 90° to each other. The foliage sprays are green above, and green marked with whitish stomatal bands below; they are strongly aromatic, with a scent reminiscent of pineapple when crushed. The individual leaves are 1–4 mm long and 1–2 mm broad on most foliage sprays, but up to 12 mm long on strong-growing lead shoots.
The cones are slender, 10–18 mm long and 4–5 mm broad, with 8–12 (rarely 14) thin, overlapping scales; they are green to yellow-green, ripening brown in fall about six months after pollination, and open at maturity to shed the seeds. The seeds are 4–5 mm long and 1 mm broad, with a narrow papery wing down each side. The pollen cones are 3–4 mm long, red or purple at first, shedding yellow pollen in spring.

Famous quotes containing the word description:
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
“Why does philosophy use concepts and why does faith use symbols if both try to express the same ultimate? The answer, of course, is that the relation to the ultimate is not the same in each case. The philosophical relation is in principle a detached description of the basic structure in which the ultimate manifests itself. The relation of faith is in principle an involved expression of concern about the meaning of the ultimate for the faithful.”
—Paul Tillich (1886–1965)
“The next Augustan age will dawn on the other side of the Atlantic. There will, perhaps, be a Thucydides at Boston, a Xenophon at New York, and, in time, a Virgil at Mexico, and a Newton at Peru. At last, some curious traveller from Lima will visit England and give a description of the ruins of St Paul’s, like the editions of Balbec and Palmyra.”
—Horace Walpole (1717–1797)
