Cedrela odorata (Spanish cedar, Mexican cedar, Cigar- box cedar, Cedro-cheiroso). The genus Cedrela has undergone two major systematic revisions since 1960. The most recent revision reduced the number of species in the genus to seven (Styles, 1981). The common cedro, Cedrela odorata L., embraces 28 other named species, including C. mexicana M. J. Roem. The taxon "C. angustifolia," a very vigorous type now in demand because of its apparent resistance to the shootborer, was left in an indeterminate status due to insufficient herbarium material. The result is that C. odorata as now constituted is a species showing a high degree of population variation.
