Species
Trisetum formerly included over 70 species. Over the past decade the genus has been split into smaller genera (including Graciliotrisetum and Sibirotrisetum) and some species placed in other genera.Barberá, P., Soreng, R.J., Peterson, P.M., Garcia-Porta, J., Romaschenko, K., Aedo, C. and Quintanar, A.
