PCA scatter-plot of the geometric morphometric analysis excluding Carex macrosolen. Squares represent sect. Abditispicae taxa, triangles represent C. phalaroides gr. taxa, and circles represent C. herteri and C. hypsipedos taxa. Utricles shapes at the margins of the graph display the extreme shapes of the morphospace for a better visualization of the utricle morphological features with greater weight within the principal components.
