Two natural hybrids, Carex ×doroyuensis (C. angustisquama × C. otayae) and C. ×thermalis (C. angustisquama × C. thunbergii), are newly reported from the Tohoku region of northern Japan. Based on morphometric and molecular genetic analyses, the hybrids were intermediate morphologically and genetically between their co-occurring parental species. The two hybrids can be distinguished from their parents by several morphological traits, including in their spikes and habitats.
