A Natural Hybrid between Carex curvicollis and C. forficula (Cyperaceae), and the Lectotypification of C. ×musashiensis

Abstract

Carex ×musashiensis Ohwi is newly reported from Miyoshi-shi, Tokushima Pref., Shikoku. This plant was described from Mt. Takao, Tokyo, as a hybrid between C. curvicollis Franch. & Sav. and C. thunbergii Steud. However, this plant is reinterpreted as a hybrid between C. curvicollis and C. forficula Franch. & Sav. by the ecological and morphological evidence at the new locality. The lectotype of C. ×musashiensis is deginated here.
