The composition of the essential oils of six populations of Thymus villosus L. ssp. villosus , an endemic species of Portugal belonging to the section Pseudothymbra Bentham of the genus Thymus (Lamiaceae), was investigated mainly by GC and GC–MS. In order to study the infraspecific variability, the results obtained by the analysis of individual plants were submitted to a principal component analysis and a cluster analysis. Four types of essential oils were found: p ‐cymene/camphor/linalol, p ‐cymene/borneol, linalol/geraniol/geranyl acetate, and α‐terpineol/camphor/myrcene. © 1997 John Wiley & Sons, Ltd.
