The tree typically grows to 40–70 m (130–230 ft) in height, and may be the tallest Abies species in the world. There are two varieties, the taller coast grand fir, found west of the Cascade Mountains, and the shorter interior grand fir, found east of the Cascades. It was first described in 1831 by David Douglas. [3]
Many are also decorative garden trees, notably Korean fir and Fraser's fir, which produce brightly coloured cones even when very young, still only 1–2 m (3 ft 3 in – 6 ft 7 in) tall. Many fir species are grown in botanic gardens and other specialist tree collections in Europe and North America. [20]
Abies sachalinensis, the Sakhalin fir, is a species of conifer in the family Pinaceae. It is found in Sakhalin island and southern Kurils ( Russia ), and also in northern Hokkaido ( Japan ). [ 2 ] The first discovery by a European was by Carl Friedrich Schmidt (1832-1908), the Baltic German botanist, on the Russian island of Sakhalin in 1866 ...
The leaves ("needles") are flattened, 2–4 cm (3 ⁄ 4 – 1 + 1 ⁄ 2 in) long and 1.5–2.5 mm (1 ⁄ 16 – 3 ⁄ 32 in) thick, spread at right angles from the shoot, and end in a point. [1] They spread on two sides, but not flat like for example in silver fir. Usually they more or less rise up forming with the shoot a V-shape empty ...
The red vole nests almost exclusively in the foliage of the trees, typically 2–50 metres (5–165 ft) above the ground, and its diet consists chiefly of Douglas-fir needles. [13] Douglas-fir needles are generally poor browse for ungulates, although in the winter when other food sources are lacking it can become important, and black-tailed ...
Abies numidica is a medium-sized to large evergreen tree growing to 20–35 meters tall, with a trunk up to 1 meter diameter. The leaves are needle-like, moderately flattened, 1.5–2.5 centimeters long and 2–3 millimeters wide by 1 millimeters thick, glossy dark green with a patch of greenish-white stomata near the tip above, and with two greenish-white bands of stomata below.
The tree produces spiky green fruits about the size of a golf ball, which turn brown and drop off the tree over an extended period beginning in fall and continuing over the winter.
The leaves are needle-like, among the longest of any fir, 4–9 centimetres (1.6–3.5 in) long, flattened in cross-section, glossy dark green above, with two whitish stomatal bands on the underside; they are arranged spirally on the shoots, but twisted at the base to lie in a flat plane either side of the shoot.
