FIGURE 1 in Taxonomic position and circumscription of Cardamine barbaraeoides (Brassicaceae), a systematically challenging taxon from the Balkan Peninsula
FIGURE 1. Map showing our sample sites and the localities of herbarium specimens from Greece revised by us. The sample sites used in the morphometric analyses are indicated by grey symbols: grey stars denote Cardamine barbaraeoides and grey crosses C. acris (see Table 2 for more details). The localities of the revised herbarium specimens are indicated by white symbols: white stars represent specimens confirmed as C. barbaraeoides (see Appendix 1) and white circles denote specimens of C. acris that were previously misidentified as C. barbaraeoides (see Appendix 2). Floristic regions of Greece according to Strid (1986) are delimited by dashed lines and named in italics.

Canonical discriminant analyses based on individual plants and two predefined groups in each analysis: Cardamine barbaraeoides and C. amara (A), C. barbaraeoides and C. acris (B), and C. barbaraeoides and C. raphanifolia (C). The analyses were based on nine morphological characters and ten ratios.
