چکیده
DOWNIE, S. R., and MCNEILL, J. 1990. A note on the taxonomic status of Euphrasia randii (Scrophulariaceae). Can. J. Bot. 68: 1531-1535. A reexamination of the phenetic relationships among the previously recognized infraspecific taxa of Euphrasia randii using principal component analyses and four clustering methods indicates that the recognition of these infraspecific taxa is unwarranted. This complex exists as one morphologically variable taxon, E. randii.
