„Magnolia stellata, commonly called star magnolia, is native to Japan. It is a small deciduous tree that typically grows 15-20’ tall with a spreading, rounded crown. It is also often grown as a large oval to rounded shrub. It is noted for its compact size and late winter to early spring bloom of star-shaped white flowers. Each flower typically has 12-18 narrow strap-like tepals.“ http://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?kempercode=l130
The subtle white-flower-scent of M.stellata is mainyl due to a mixture of (E)-cinnamyl alcohol (2.8%), (Z)-cinnamyl alcohol (1.1%), (E)-cinnamaldehyde (0.4%), 3-phenylpropanol (0.2%), 2-phenylethanol (0.3%), benzyl tiglate (0.7%), benzyl isovalerate (0.2%), benzyl 2-methylbutyrate (3.6%), 2-aminobenzaldehyde (0.2%), and benzaldehyde (15.1%) embedded in a matrix of benzyl alcohol (52.6%) and benzyl benzoate (17.3%).
