| Sumario: | Using flavonoid and phenolic compound constituents, methods of numerical taxonomy were applied to ten species and some cultivars of three species of the genus Colica. The purpose was to investigate the genetic relatiottships among them The results pointed out C. eugcnioides as one parent of the allotetraploid species C. arabica, but could not decide between C. liberica and C. canephora as the other parent. No evidence for a relationship between C. congensis and C. arabica has been found. It is suggested a taxonomic review of the genus Coffea, since species belonging to separated subsections according to Chevalier (3), showed more affinity than some species belonging the same subsection.
