The leaf essential oils of four members of the genus Austromyrtus sens. lat. (three undescribed and one described species), the A. lasioclada group have been examined. All species produced oils in 0.1‐0.4% yields, based on fresh leaves. The oils were almost entirely sesquiterpenic in nature. In A. lasioclada (F. Muell.) L.S. Sm. the main compounds were δ‐cadinene (8‐14%) and germacrene‐D (4‐12%). A. . sp. (Blackall Range P.R. Sharpe 5387) gave an oil in which the main components were α‐copaene (12‐16%), β‐caryophyllene (4‐20%) and allo‐aromadendrene (3‐13%). A sp. (Upper Mudgeeraba Creek N.B. Byrnes +4069), also yielded an oil with α‐copaene (8‐15%), β‐caryophyllene (3‐8%) and allo‐aromadendrene (8‐14%) as the principal components. The last member of the group, A. sp. (Main Range P.R. Sharpe 4877) produced an oil in which the main components were spathulenol (8‐12%) and allo‐aromadendrene (7‐9%).
