Abstract

Using gas-liquid chromatography and analyzing terpenoid contents the clarification of some taxonomic problems in Bursera is attempted. Initial experiences indicated a considerable intraspecific chemical variability and it was found that sampling of various individuals per population is necessary in order to achieve an adequate characterization of most of the species. A concrete case is studied of a population from the region of Cañón del Zopilote (state of Guerrero, Mexico), distinguished by a conspicuous pubescence and apparently reproductively isolated from remaining individuals of B. schlechtendalii Engl., which are perfectly glabrous. The terpenoid spectrum of this population is shown to be significantly different and such fact allows to determine its status of independent species, described as such in this paper.
