Abstract
The author presents the results of a statistical and populational analysis of the morphological characters of the genus Dactylis. Biometric studies of natural populations were carried out simultaneously with observations of samples from experimental cultures. It has been recognized that in Poland the genus Dactylis is represented by one species, D. glomerata L., within which three subspecies have been distinguished: subsp. glomerata, subsp. aschersoniana (Graebn.) Thell. and subsp. slovenica (Dom.) Dom. The author gives a key to the determination of these subspecies.
