Fig. 3 in Comparing essential oils from Australia's 'Victorian Christmas Bush' (Prostanthera lasianthos Labill., Lamiaceae) to closely allied new species: Phenotypic plasticity and taxonomic variability

Fig. 3. PCA Analysis of essential oils from taxa currently circumscribed as P. lasianthos or P. eungella. LL = P. lasianthos subsp. lasianthos; LS = P. lasianthos subsp. subcoriaceae; Eu = P. eungella; BM = P. sp. Bald Mountain; MK = P. sp. Mount Kaputar; PL= P. sp. Point Lookout; SG = P. sp. Schofields Gap; WG = P. sp. Wollomombi Gorge. A) The PCA scores plot, conveying the pronounced grouping of essential oil profiles according to the presence and absence (or trace amount) of 1,8-cineole. B) The loading plot, showing principle components that influenced chemometric clusters. See Fig. 4 for a clearer clustering pattern of individual taxa.
