Betula pubescens Ehrh. - Betulaceae - downy birch, moor birch, Moor-Birke
Betula pubescens subsp. pubescens - syn. Betula alba L. - white birch
Betula pubescens subsp. tortuosa - syn. Betula tortuosa Ledeb. - mountain birch

Deciduous tree, up to 20m tall, native to North Europe and West Asia.

Fresh birch leaves own a very pleasant „green“ smell. Analyses showed that (Z)-3-hex-en-1-ol and 1-hexanol are major constituents of the birch-leaf volatiles from both B.pubescens (27%) and B.pendula (19%). Other compounds present are (E)-2-hexenal, (E)-beta-ocimene, hexyl acetate, (E)-2-hexen-1-ol, and (E)-alpha-farnesene.

The rectified oil of birch bark tar is used in perfumery for smoky-leathery-phenolic notes. The tar is manufactured by controlled heating of bark of various birch species (mainly white birch). Several methyl- and methoxy-substituted phenols and some naphtalene derivatives are found in the headspace of the tar (which is used in ancient times as adhesive for hafting lithic tools on wooden shaft or for repairing and decorating ceramic vessels). Volatile components of the liquid tar include phenol and derivatives like 2-methylphenol, 2-methoxyphenol (guaiacol), dimethylphenol, trimethylphenol, 2-methoxy-4-methylphenol, 4-ethyl-2-methoxyphenol e.g.; naphtalenes like methylnaphtalene, ethylnaphtalene, and trimethylnaphtalene, and sesquiterpenes like calamenene.
