Franklinia alatamaha W. Bartram ex Marshall - Theaceae - Franklin tree, Franklinie
„Franklinia is a monotypic genus in the tea plant family, Theaceae. The sole species in this genus is a flowering tree, Franklinia alatamaha, commonly called the Franklin tree, and native to the Altamaha River valley in Georgia in the southeastern United States. It has been extinct in the wild since the early 19th century, but survives as a cultivated ornamental tree.“ http://en.wikipedia.org/wiki/Franklinia
The scent of Franklinia flowers is „strongest and most equilibrated between 9 a.m. and 1 p.m… individual flowers showed remarkable differences… The first one was characterized by pleasant henna-, freesia-, and tea flower main note, in the second methyl benzoate and methyl salicylate came somewhat on top, and in the third one the spiciness of eugenol became clearly recognizable… The analytical investigation of the trapped headspace samples revealed that the aromatic/spicy compounds mentioned above are embedded in a matrix dominated by carotenoid-derived compounds as β-ionone, dihydro-β-ionone, and α-ionone which tend to a quick adaption, provoking after a while a temporary anosmia.“
