Description
The leaves are thick, tough and scale-like, triangular, 3–4 cm long, 1–3 cm broad at the base, and with sharp edges and tip. They persist for 10–15 years or more, so cover most of the tree except for the older branches.
It is usually dioecious, with the male and female cones on separate trees, though occasional individuals bear cones of both sexes. The male (pollen) cones are oblong and cucumber-shaped, 4 cm long at first, expanding to 8–12 cm long by 5–6 cm broad at pollen release. The tree is wind pollinated. The female (seed) cones, which mature in autumn about 18 months after pollination, are globose, large, 12–20 cm diameter, and hold about 200 seeds. The cones disintegrate at maturity to release the 3–4 cm long nut-like seeds, which are then dispersed by jays and squirrels.

Famous quotes containing the word description:
“I fancy it must be the quantity of animal food eaten by the English which renders their character insusceptible of civilisation. I suspect it is in their kitchens and not in their churches that their reformation must be worked, and that Missionaries of that description from [France] would avail more than those who should endeavor to tame them by precepts of religion or philosophy.”
—Thomas Jefferson (1743–1826)
“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)
“Do not require a description of the countries towards which you sail. The description does not describe them to you, and to- morrow you arrive there, and know them by inhabiting them.”
—Ralph Waldo Emerson (1803–1882)
