New subspecies are recognised in E. leucophloia Brooker subsp. euroa (tree to 10 m), E. oligantha Schauer subsp. modica (tree to 15 m tall), and E. pruinosa Schauer subsp. tenuata (tree or mallee to 6 m tall). All new taxa fall within subgenus Symphyomyrtus, in the three sections Transversaria, Exsertaria and Adnataria. New taxa are mapped, and keys are presented in cases where existing keys will not discriminate taxa. Selected taxa are illustrated.
