Notes
Very similar to C. nigra (L.) Reich., a common European and N. American species, and sharing with it an extreme polymorphism. Carex gaudichaudiana is characterized by the strongly nerved, more distinctly beaked utricles, and the lower bracts usually exceeding the terminal spikelet.
The type of C. gaudichaudiana is from Australia. The Asiatic plants have been distinguished as var. thunbergii (Steud.) Kuk.
The differences between the Australian plants and the Asiatic ones are but slight; see Koyama, l.c.
Carex appendiculata (Trautv.) Kuk., from E. Siberia, according to Koyama also only a variety of C. gaudichaudiana, is C. nigra (L.) Reich.
