Research concerning the variability of the flowers morphological features of some orchid species from Anina Mountains

The Anina Mountains is one of the areas where the field literature indicates a whole variety of orchid species. The purpose of this paper was to evaluate the variability of the flowers morphological features of six orchid species identified in this area. The identified species were divided into two groups considering the appearance of the lip: species with three - lobed lip and species with the lip composed of two parts. The variability of the features was assessed by biometric measurements made during the flowering season of species. The analyzed features were divided into two groups: the general morphological features of the flowers and the elements of the flowers morphological features. The general morphological features of the flowers had the highest variability in all analyzed species.
