Notes: Scent was collected from whole flowers, petals or anthers from stamens (staminodes) of hermaphrodite and female flowers. Wounding volatiles have been excluded from this table. Values are mean percent of total blend ± SE.
† Compound identity verified by co-retention with known standards on 2 GC columns;
‡ Compounds consistent with published accounts of relative retention time, but no standard was available.
