Abstract
The essential oils of 23 species of Austromyrtus sens. lat. have been examined. Austromyrtus gonoclada contains 2-hydroxy-4,6-dimethoxy-3,5-dimethylacetophenone as its principal component. The remaining 22 species fall into two groups in which the leaf essential oils are either dominated by sesquiterpenes or have monoterpenes accounting for 50% or more of the oil. Into the first group fall both chemotypes of A. floribunda, one chemotype of A. hillii, A. inophloia, A. minutiflora, A. pubiflora, A. shepherdii, A. sp. (Bamaga, B. P. Hyland 10235), A. sp. (Brookfield, L. W. Jessup 155), A. sp. (McIlwraith Range, B. P. Hyland 11148), A. sp. (Pinnacle Track, P.I. Forster PIF15535). The second group, which has monoterpenes accounting for 50% or more of the oil, comprises Austromyrtus acmenoides, A. bidwillii, A. dallachiana, A. fragrantissima, one chemotype of A. hillii, A. racemulosa, A. sp. (Byerstown Range, G. P. Guymer 2037), A. sp. (Forty Mile Scrub, G. C. Stocker 1758), A. sp. (Mt. Beatrice, P. I. Forster PIF14662), A. sp. (Mt. Lewis, P.I. Forster PIF15613), A. sp. (Mt. White, P.I. Forster PIF13461), A. sp (Danbulla, L. S. Smith 10123), and A. sp. (Spencer Creek, P. I. Forster PIF13701).
