Leptospermum scoparium Myrtaceae

New Zealand showing general locations of the three chemotypes of Leptospermum scoparium 

Compound Australian N.Z. North. N.Z. East Cape N.Z. South 

Included in the table are data for L. scoparium obtained from five sites in Australia. The Australian material exhibited a level of a-pinene approaching that of the northern race from New Zealand, but was clearly characterized by the highest level of 1,8-cineole observed in the study, along with the highest value for total monoterpenes and lowest value for total sesquiterpenes. The authors noted the need for further taxonomic study, particularly of the Australian material. 

Returning to the terpenes for a moment, it is interesting to note that Perry et al. (1997b) also examined the essential oils of Kunzea ericoides (A. Rich.) J. Thompson 

Chionochloa, known locally as snow tussock, consists of 22 species, 21 of which are native to New Zealand. The remaining species occurs in southeastern Australia and does not figure in the discussion. Studies of triterpene methyl ethers (TMEs) have revealed the existence of different chemodemes (Connor and Purdie, 1976, 1981). In some instances, it was shown that TMEs were present in populations of a given species in one part of its range but absent from others arundoin [57] (see Fig. 2.12 for structures 57-59) was identified from plants collected at Harpers
