Description
Pinus roxburghii is a large tree reaching 30–50 m (98–160 ft) with a trunk diameter of up to 2 m (6.6 ft), exceptionally 3 m (10 ft). The bark is red-brown, thick and deeply fissured at the base of the trunk, thinner and flaky in the upper crown. The leaves are needle-like, in fascicles of three, very slender, 20–35 cm (7.9–14 in) long, and distinctly yellowish green.
The cones are ovoid conic, 12–24 cm (4.7–9.4 in) long and 5–8 cm (2.0–3.1 in) broad at the base when closed, green at first, ripening glossy chestnut-brown when 24 months old. They open slowly over the next year or so, or after being heated by a forest fire, to release the seeds, opening to 9-18 cm broad. The seeds are 8–9 millimetres (0.31–0.35 in) long, with a 40 mm (1.6 in) wing, and are wind-dispersed.
Pinus roxburghii is closely related to Pinus canariensis (Canary Island pine), Pinus brutia (Turkish pine) and Pinus pinaster (maritime pine), which all share many features with it. It is a relatively non-variable species, with constant morphology over the entire range.

Famous quotes containing the word description:
“To give an accurate description of what has never occurred is not merely the proper occupation of the historian, but the inalienable privilege of any man of parts and culture.”
—Oscar Wilde (1854–1900)
“The type of fig leaf which each culture employs to cover its social taboos offers a twofold description of its morality. It reveals that certain unacknowledged behavior exists and it suggests the form that such behavior takes.”
—Freda Adler (b. 1934)
“The Sage of Toronto ... spent several decades marveling at the numerous freedoms created by a “global village” instantly and effortlessly accessible to all. Villages, unlike towns, have always been ruled by conformism, isolation, petty surveillance, boredom and repetitive malicious gossip about the same families. Which is a precise enough description of the global spectacle’s present vulgarity.”
—Guy Debord (b. 1931)
