Phenetic relationships among Argentine species of Alstroemeriaceae

Cluster analysis and ordination by principal component analysis (PCA) were used to study phenetic relationships among the Argentine species of Alstroemeriaceae and to point out the characters that contribute to the differentiation between Alstroemeria L. and Bomarea Mirb. A total of 123 specimens (a...
