A reappraisal of the Carex arenaria complex in Flanders (Belgium)

The taxonomy of Carex section Ammoglochin is complex due to the faint morphological species boundaries and overlapping ecological niches. This study focusses on species boundaries within the C. arenaria complex, in particular C. arenaria, C. brizoides and C. pseudobrizoides. Carex pseudobrizoides is morphologically very similar to C. arenaria, but also shares some features with C. brizoides, which has sometimes led to the assumption of a hybridogenic origin. We studied the morphology, ecology and distribution of these species in Flanders, and combined this with DNA sequence data (plastid encod... Mehr ...
