Abstract
Coprosma robusta, C. repens, and C. crassifolia all have distinctive complements of 5 to 13 flavonoid compounds (quercetin and kaempferol derivatives). Two putative hybrids, C. robusta × C. repens and C. repens × C. crassifolia, both show additivity of the parental flavonoid sets (with the possible exception of some compounds present as traces in one parent). Flavonoid profiles should provide a useful tool in identifying the parentage of hybrids in Coprosma.
