While treating the data on Asiatic lily cultivars by means of the principal components method we came across a new variation pattern that combines several correlated features and reflects interspecific variation level. We suggest, that the pattern revealed might be considered in the light of two directions of home biological thought. On the one hand, that is revelation and comparison of feature variation patterns; these investigations are connected with N. Vavilov’s name and in later period - with S. Meien’s name and his work on organism typology. On the other hand, that is research on correlation in feature variation; in this area the works of P. Terentiev on correlation pleiads method and later works of other authors, applying the principal components method, are known. Variation patterns, revealed by the methods of correlation pleiads and principal components, might correspond to the definite taxonomic level, and that is of particular importance. Botanical collections, combining cultivars and species of one genus, give the richest material for typological investigations.
