'''''Tsuga dumosa''''', commonly called the '''Himalayan Hemlock''' is a species of [[conifer]] native to the eastern [[Himalayas]]. It occurs in parts of [[India]], [[Burma]], [[Vietnam]], [[Tibet]], and [[China]]. Within its native range the tree is used for construction as well as for furniture. In [[Europe]] and [[North America]], it is occasionally encountered as an ornamental species and was first brought to the [[United Kingdom]] in 1838.
''T. dumosa'' is a tree growing 20 to 25 metres (65 to 80 ft) high and exceptionally to 40 m (130 ft). The [[diameter]] at breast height is typically 40 to 50 cm (16 to 20 in), but can be beyond 100 cm (40 in).<ref name="Data"/> The crown on small trees is ovoid and their form is like that of pendulous bushes. Older trees tend to have multiple stems from one or two sinuous [[bole]]s, especially in cultivation. The crown of mature trees is broad, irregular-pyramidal and open. The [[bark]] is a similar to that of an old [[larch]]: somewhat pinkish to grey-brown and heavily ridged with broad, shallow, flaky fissures.<ref name="Mitchell">{{cite book

Branches that are 2 to 3 years old are greyish brown or dark grey with leaf scars. The [[wood]] from the tree is a brownish yellow with a fine structure and straight veins.<ref name="Data"/>
The [[leaves]] are spirally arranged, pointing forward on the branches and placed distantly from one another compared to other species in the genus ''[[Tsuga]]''. They are linear in shape, and 10 to 25 mm (0.5 to 1 in) long by 2 to 2.5 mm (0.07 to 0.1 in) wide. The ends are obtuse or rounded, and very occasionally emarginate. The upper surface of the leaves is green and shiny, while the undersides have 2 wide silvery [[stomata]]l bands. The upper half of the leaves usually have small dents on the margins, i.e. the margins are rarely entire. The [[midrib]] is concave on the upper surface. <ref name="Data"/><ref name="Mitchell"/>
The stamenate [[flower]]s are globose in shape, solitarily arranged and axillary. The [[anther]]s are a green-yellow in colour and they lack an air sac. The pistillate flowers are round-ovate in shape, also solitarily arranged, terminal and slightly down-curved. They have many spiral scales with 2 [[ovule]]s contained within each scale. The [[seed]]s are about 9 mm (0.4 in) long, ovate in shape, brown in colour and have thin wings in their upper parts. Flowering occurs from April to May and fruiting from October to November.<ref name="Data"/>
