The essential oils of species of Leptospermum allied to L. blakelyi have been examined. L. brevipes, L. neglectum, L. parvifolium, L. sp. (Woodgate, P. I. Forster, PIF 13959) produced oils which were monoterpene in character, with α‐pinene usually being the major component. The oil yield in these species was up to 0.7%. L. blakelyi, L. multicaule, L. namadgiensis and L. sericatum gave oils which were sequiterpenoid in character. These species usually gave oil trace yields (0.2%). L. divaricatum and L. microcarpum both showed mixed monoterpenoid and sequiterpenoid forms. The oil yields for the mixed and sequiterpenoid forms was <0.1%, while for the monoterpenoid form the yield was up to 0.6%. © 1998 John Wiley & Sons, Ltd.
