Abies spectabilis var. densa(Griff.) Silba

Abies densa, the Bhutan fir, is a conifer species in the family Pinaceae. It is sometimes included in the East Himalayan fir (A. spectabilis) as a variety.

Found in Bhutan, China, India, and Nepal, it is not considered a threatened species by the IUCN.

Also called the Himalayan alpine fir, Abies densa is a dominant conifer in the upper coniferous belt of the central and eastern Himalayas from Nepal, Sikkim, Bhutan, and adjacent Tibet to Burma (Myanmar) in altitudes between 2800 and 3700 m. It is a tree up to 3040 (sometimes to 60) m, with trunk diameters sometimes reaching 2.5 m. The bark is breaking to thick angular plates, the branchlets light grayish-yellow when young, later grayish-brown to gray. The needles are up to 4.5 cm long, with somewhat recurved margins. The cones are up to 10 cm long, bluish gray or dark blue to bluish brown, with bract length varying among individuals (slightly included or with more or less protruding, straight or recurving tips). Sometimes lumped with Abies spectabilis, a species of more westerly distribution, Abies densa differs from the former in several traits, e.g., its leaves are shorter, narrower, somewhat recurved, and are less silvery-white below; Abies densa also has smaller cones with bracts relatively longer than in Abies spectabilis.

Fir Genus of plants in the conifer family Pinaceae

Firs (Abies) are a genus of 48–56 species of evergreen coniferous trees in the family Pinaceae. They are found through much of North and Central America, Europe, Asia, and North Africa, occurring in mountains over most of the range. Firs are most closely related to the genus Cedrus (cedar). Douglas firs are not true firs, being of the genus Pseudotsuga.

<i>Abies recurvata</i> Species of conifer

Abies recurvata is a species of conifer in the family Pinaceae. It is found only in China.

It occurs in the drier, colder northern regions of central China in Sichuan and Gansu provinces at elevations between 2300 and 3600 m, usually on windy cliffs or in deep river valleys. Sometimes, however, also appears in dry low scrub on exposed mountain slopes. The most typical associated conifer species include Juniperus convallium, Juniperus formosana var. mairei, Juniperus squamata var. fargesii, Juniperus tibetica, Picea asperata, and Picea wilsonii. Abies recurvata is a small to medium-sized tree mostly with conical crown, occasionally reaching a height of 40 m, and a trunk diameter of 0.8 metres. It has rather smooth gray or rusty brown bark, at first shedding in thin plates, becoming grayish-brown and detaching in thick plates. The branchlets are grayish-white or light yellow with 1.2–2.5 centimetres (0.47–0.98 in) long needles horizontally outspreading on shade branches, radially outspreading on fertile branches; often thick and recurved, green to gray above and densely set with stoma-lines, with 2 light grayish-green stomatal bands below. Abies recurvata has 4–8 centimetres (1.6–3.1 in) long ovoid or cylindrical-ovoid, gray- or purplish blue cones; the bracts are somewhat shorter than the cone-scales, included or with slightly exposed tips.
