'''''Tsuga sieboldii''''', also called the '''Southern Japanese Hemlock''', or in [[Japanese (language)|Japanese]], simply '''Tsuga''', is a [[conifer]] native to the [[Japan|Japanese]] islands. In [[Europe]] and [[North America]] the tree is sometimes used as an ornamental and has been in cultivation since 1861. The tree is often multiple-stemmed from the base and the dense crown is broadly conical and pointed. The [[bark]] is a dark pink-grey in colour. It is smooth with horizontal folds when the tree is young, but later cracks into squares and become flaky. The glabrous [[shoot]]s are a pale shining buff, but they may vary to white or pale brown. The base of the [[petiole (botany)|petiole]] is red-brown. The [[leaf|leaves]] are densely set in irregular flat rows. They are broad and stubby in comparison to other species of the genus ''[[Tsuga]]'', and they vary in length from 0.7 cm to 2 cm long by about 0.2 cm wide. They are blunt with notched tips and shiny dark green above. The underside of the leaves has two broad, dull white [[stomata|stomatal]] bands. The [[buds]] are narrow based and ovoid, dark orange in colour. Their scales are convex.<ref name="Mitchell">{{cite book | last =Mitchell | first =Alan | authorlink =Alan Mitchell | coauthors = | title =Trees of Britain & Northern Europe | publisher =Harper Collins Publishers | date =1974 | location =London | pages = 146 | id =ISBN 0-00-219213-6 }}</ref> The stamenate (i.e. male) [[flower]]s are terminal on weak shoots.
