A comparison of genetic distances between the short-beaked species (C. saxatilis, C. membranacea, and C. rotundata) and some long-beaked species (C. utriculata, C. rostrata, and C. vesicaria) of Carex section Vesicariae indicates that the short-beake

Carex (sect. Albae) mckittrickensis is described as a new species from Guadalupe Mountains National Park, Texas. It is similar to C. eburnea but has larger staminate and pistillate scales and larger perigynia with a longer beak. It is over 1000 km di

Within the short-beaked taxa of Carex sect. Vesicariae, C. membranacea and C. rotundata were found to form a close species pair with anatomical data providing the most convincing evidence for the separation of these two species. Carex membranacea has

Morphological studies of the short-beaked members of Carex sect. Vesicariae have indicated that three species can be recognized: C. saxatilis (incl. C. miliaris and C. physocarpa), C. membranacea, and C. rotundata. To assess genetic relationships amo
