New combinations, new names, typifications, and a new section, sect. <I>Hispanica</I> in <I>Koeleria</I> (Poeae, Poaceae)

Abstract

Based on morphological and molecular evidence we transfer the species of Trisetum sect. Trisetaera, T. hispidum, and Trisetokoeleria taymirica into Koeleria, describe Koeleria sect. Hispanica, and provide a new generic emendation. A total of 49 new combinations or new names are included. Additionally, we lectotypify Avena clarkei Hook f., Avena micans Hook. f., Avena subalpestris Hartm., Avena subspicata var. agrostidea Laest., Trisetum pubiflorum Hack., Trisetum spicatum f. minor Kom., and Trisetum spicatum f. umbrosum Kom.
