    The cones are pendulous, slender cylindrical, 6–10 cm (2 + 1 ⁄ 2 –4 in) long [5] and 2 cm (3 ⁄ 4 in) broad when closed, opening to 3 cm (1 + 1 ⁄ 4 in) broad. They have thin, flexible scales 15–20 mm ( 5 ⁄ 8 – 3 ⁄ 4 in) long; the bracts just above the scales are the longest of any spruce, occasionally just exserted and visible ...

    Coast Douglas-fir is the fourth tallest conifer and fifth tallest of all trees in the world (after sitka spruce).Currently, coast Douglas-fir trees 60–75 metres (197–246 ft) or more in height and 1.5–2 metres (4.9–6.6 ft) in diameter are common in old growth stands, [4] and maximum heights of 100–120 metres (330–390 ft) and diameters up to 4.5–5.5 metres (15–18 ft) have been ...

    Other researchers have developed models of maximum height for Coast Douglas-fir (Pseudotsuga menziesii var. menziesii) trees that yield similar estimates of 109–138 meters (357–452 feet), [46] a range that includes the height of the tallest reliably-measured historical (dead) specimen, a 126-meter tree.

    The buds are a distinctive narrow conic shape, 3–6 mm (1 ⁄ 8 – 1 ⁄ 4 in) long, with red-brown bud scales. The leaves are spirally arranged but slightly twisted at the base to be upswept above the shoot, needle-like, 2–3 cm ( 3 ⁄ 4 – 1 + 1 ⁄ 4 in) long, gray-green to blue-green above with a single broad stomatal patch, and with ...

    American Forests, for example, uses a formula to calculate Big Tree Points as part of their Big Tree Program [3] that awards a tree 1 point for each foot of height, 1 point for each inch (2.54 cm) of girth, and ¼ point for each foot of crown spread. The tree whose point total is the highest for that species is crowned as the champion in their ...

    It can grow to 25 metres in height, with a stem diameter of up to 16 cm, [1] but is more typically 15–20 m tall and 12 cm in diameter. [2] It has unusual stilt roots, the function of which has been debated. Many species of epiphyte have been found growing on the palms. The palm is pollinated by beetles, and various organisms eat its seeds or ...

    The Fouquieria columnaris trunk is up to 24 inches (61 centimeters) thick, off-white in color, with few or no major branches and with numerous thin, twiggy branches sticking out at right angles, all covered with small leaves 1.5–4 cm (0.59–1.57 in) long. They can grow to a height of 20 meters (almost 70 feet), but the tallest, in Montevideo ...

    The cones are small (but much longer than those of any other species of hemlock), pendulous, cylindrical, 3 to 8 cm (1 to 3 in) long and 8 to 10 mm (5 ⁄ 16 to 3 ⁄ 8 in) broad when closed, opening to 12 to 35 mm (1 ⁄ 2 to 1 + 3 ⁄ 8 in) broad, superficially somewhat like a small spruce cone.
