Abstract
Biochemical and morphological components of 16 Pelargonium species and the P. xhortorum interspecific complex were examined. Inflorescences and leaves of each species were analyzed for anacardic acids and the p resence of glandular trichomes. Three species of the section Ciconium, P. acetosum, P. frutetorum, and P. inquinans, produced anacardic acid s in association with glandular trichomes. Only P. inquinans and P. fr utetorum contained omega 5-anacardic acids. An evolutionary model for the origin of anacardic acids and omega 5-desaturation is proposed.
