Our own observations reveal that the achenes of this taxon, and especially the way these are very loosely involved by the strongly inflated utricles, are an almost perfect match for the achenes and utricles of C.

The phylogenetic position of Carex baldensis is particularly significant because it suggests that rachillae axes in fertile utricles have evolved into complete androgynous lateral spikes (Reznicek, 1990; Starr et al.
