Table S1. Volatiles means (nanograms per gram of dry leaf tissue) after one round of outlier removal (outlier values greater than three standard deviations about full data mean were removed). apinene = α-pinene, chexylac = cis-hexeyl acetate, cocimine = cis-ocimene, dimeth = dimethyl-3-methylene-2-vinylcyclohexane, dodec = dodecane, ciclyclop = bicyclopentyl-2-one, trideca = tridecane, caryphy = caryophyllene, tetradec = tetradecane, farnesen = α-farnesene, pentadec = pentadecane.
