Résumé :	The leaf oils of the Australian members of the genera Geijera and Coatesia have been examined by GC and GC/MS. Coatesia paniculata gave a consistent oil in which the principal components were α-pinene (27–57%) and β-caryophyllene (4–12%). Geijera linearifolia gave a leaf oil dominated by spathulenol (10–17%), geranyl acetate (4–9%), bicyclogermacrene (3–6%) and (E,E)-farnesol (23–30%). Four chemotypes of Geijera parviflora were detected: (1) in which geijerene/pregeijerene and linalool predominated, (2) in which linalool and α- and β-eudesmol predominated, (3) in which α-pinene and camphene predominated and (4) in which phloroacetophenone dimethyl ether predominated. Geijera salicifolia also existed in several chemotypes, one of which contained large amounts of phloroacetophenone dimethyl ether (> 65%). Also present in this particular chemotype was the geijerene/pregeijerene and attendant C12H18 complex, totaling approximately 5%. In a second sample of this chemotype, this complex was absent. A second chemotype of this species contained α-pinene (38.6%), camphene (22.4%) and limonene (7.5%) as principal components.
