| | The genus of Stanhopea (occurring throughout much of the Neotropics from northwestern Mexico to southeastern Brazil) was used as a detailed example of the variation and species specificity in floral fragrance composition. Components of the floral fragrance (adsorbed at a Tenax tube and desorbed with microdistillation) of S.tigrina were p-cymene (2.0%), phenylethanol (6.5%), benzyl acetate (1.0%), phenylethyl acetate (69.4%), indole (3.4%), (Z?)-cinnamyl acetate (1.0%), and (E?)-cinnamyl acetate (15.8%). \\ |

| "Its diffusive, 'aromatic-spicy-floral' scent is extremly sweet. One would not expect to contain more than 90% phenylethyl acetate; in fact, it is difficult even to detect this well-knwon substance in the scent... the unusual accord is attributeable to minor constituents accompaning phenylethyl acetate, in particular β-ionone and derivatives, coumarin, p-hydroxy phenylbutanone (raspberry ketone), and vanillin." \\ | "Its diffusive, 'aromatic-spicy-floral' scent is extremly sweet.
