-Shrub or tree, native to northern Europe (European Bird Cherry, Prunus padus var. padus) and Asia (Asian Bird Cherry Prunus padus var. commutata). White flowers with strong sweet and amine-like smell.
+Shrub or tree, native to northern Europe (European Bird Cherry, Prunus padus var. padus) and Asia (Asian Bird Cherry Prunus padus var. commutata); leaves ovate to obovate, rounded or cordate at the base, serrulate; flowers in erect to pendent racemes, white, fragrant, calyx receptacle hairy within; fruit black, globular, with bitter taste. \\

-"The volatiles of European bird cherry flowers were enriched by the vacuum headspace method. In the obtained odor concentrate more than 70 compounds were identified by GC/MS. The compounds, which are responsible for the typical odor, are benzaldehyde, 2-phenylethyl alcohol, phenylacetaldehyde, phenylacetonitrile, linalool and a number of nitrogen-containing constituents like indole, methyl anthranilate, anthranilic aldehyde, 2-aminoacetophenone and nicotinic aldehyde. Some compounds have previously not been found in nature (methyl esters of N-formyl-leucine and N-formyl-isoleucine, N-(2-acetylphenyl)-formamide and 1, 4-dihydro-2-methyl-2H-3, 1-benzoxazine)." \\
+"Literature illustrated a wide geographical range. The species thrives in different habitats. Literature further describes three subspecies and more than twenty varieties. The taxonomical subdivision of the species is disputed and unsolved yet." \\

+"Bark and seeds contain the cyanogenic glycoside amygdalin." \\

+"The flowers are hermaphroditic and pollinated by bees and flies. The fruit is readily eaten by birds, which do not taste astringency as unpleasant. Bird-cherry Ermine moth (Yponomeuta evonymella) uses bird-cherry as its host plant, and the larvae can eat single trees leafless." \\
+[[http://en.wikipedia.org/wiki/Prunus_padus]]
+The odor of the flowers "... can be described as clear cherry-flower-like with spects of orange flower, jasmin and elder flower and a characteristic undertone of anthranilate-like compounds." Main constituents of the vacuum headspace concentrate were benzaldehyde, anthranilic aldehyde, benzyl alcohol, 2-phenylethanol, linalool, (E)-8-oxolinalool, and (E,E)-α-farnesene.  1,4-Dihydro-2-methyl-2H-3,1-bezoxazine (odor: quinoline-like) as the cyclic product of anthranilic alcohol and acetaldehyde is found in the vacuum headspace concentrate in amounts of 0.1-1%. In pure form it cleaves acetaldehyde in perceptible amounts. \\
+"The compounds, which are responsible for the typical odor, are benzaldehyde, 2-phenylethyl alcohol, phenylacetaldehyde, phenylacetonitrile, linalool and a number of nitrogen-containing constituents like indole, methyl anthranilate, anthranilic aldehyde, 2-aminoacetophenone and nicotinic aldehyde." \\
