 "The major oxygenated constituents [of the hexan extract from concrete of G.taitensis flowers] were found to be linalool (4.4%), methyl salicylate (2.5%), (Z)-3-hexenyl benzoate (2.2%), dihydroconiferyl alcohol (1.1%), [[http://www.thegoodscentscompany.com/data/rw1010652.html|(Z)-3-hexenyl salicylate]] (0.7%), benzyl benzoate (6.2%), dihydroconiferyl acetate (12.2%), 2-phenylethyl benzoate (6.2%), benzyl salicylate (2.5%), geranyl benzoate (2.1%) and 2-phenylethyl salicylate (2.2%). The identification of numerous dihydroconiferyl esters appears to be unique to this species." \\ "The major oxygenated constituents [of the hexan extract from concrete of G.taitensis flowers] were found to be linalool (4.4%), methyl salicylate (2.5%), (Z)-3-hexenyl benzoate (2.2%), dihydroconiferyl alcohol (1.1%), [[http://www.thegoodscentscompany.com/data/rw1010652.html|(Z)-3-hexenyl salicylate]] (0.7%), benzyl benzoate (6.2%), dihydroconiferyl acetate (12.2%), 2-phenylethyl benzoate (6.2%), benzyl salicylate (2.5%), geranyl benzoate (2.1%) and 2-phenylethyl salicylate (2.2%).

 +The headspace (SPME) of G.taitensis growing in New Caledonia contained mainly esters of (Z)-3-hexen-1-ol (free alcohol 0.8%) like (Z)-3-hexen-1-yl tiglate (39.6%), (Z)-3-hexen-1-yl acetate (2.7%), (Z)-3-hexen-1-yl butanoate (1.2%), (Z)-3-hexen-1-yl 2-methylbutanoate (0.5%), (Z)-3-hexen-1-yl (Z)-3-hexenoate (2.7%), and (Z)-3-hexen-1-yl benzoate (0.5%), together with linalool (11.8%), phenylacetaldoxime methyl ether (9.0%), methyl salicylate (18.0%), and 1H-indole (2.9%). Minor components were also 2-phenylethanol (0.7%), phenylacetonitrile (1.3%), 2-phenyl acetate (0.6%), hexyl tiglate (1.8%), and butyl benzoate (1.3%) e.g. \\
 +An inhouse-prepared absolute of the flowers contained as key odor contributors linalool (5.5%),  1-nitro-2-phenylethane (0.13%), phenylacetonitrile (0.88%), methyl salicylate (6.86%), together with 1H-indol (1.1%), (Z)-3-hexen-1-yl benzoate (9.0%), and (Z)-3-hexen-1-yl salicylate (5.1%) e.g. \\
