✦ Synopsis

The essential oils of the five indigenous myrtaceous species of Lord Howe Island have been examined. Leptospermum polygalifolium Salisb. subsp. howense J. Thompson produced an oil in 0.9-1% yield in which the major compounds were the a-, Band yeudesmols. These three compounds accounted for over 75% of the oil. Melaleuca howeana Cheel yielded an oil in approximately 0.1% yield in which the major compounds were 1,8-cineole (5-40%) and globulol(8-l8'Y0). Cleistocalyxfullageri (F. Muell.) Merr. & Perry gave an oil, in approximately 0.1% yield, in which the major compound was a-pinene. Metrosideros sclerocarpa Dawson ex P. S. Green produced an oil in at most 0.05% yield in which the major compound was allo-aromadendrene (75%), while Metrosideros nervulosu C. Moore & F. Muell. gave an oil in approximately 0.01% yield in which the major compounds were sesquiterpene alcohols together with n-hexadecanol.
