Morphological variation in Astragalus muelleri (Fabaceae) from Balkan and Italian populations
Morphological variation in Astragalus muelleri (Fabaceae) from Balkan and Italian populations
A morphometric study aimed at comparing Italian and Balkan populations of Astragalus muelleri is carried out. Based on univariate (ANOVA, Tukey HSD test) and multivariate (DA) analysis results, a new subspecies to accommodate the Italian populations (A. muelleri subsp. etruscus subsp. nov.) is described. This subspecies is slightly distinct from the typical Balkan populations for its fewer and larger flowers, producing shorter fruits.
