Taxonomy

The first recorded description of the species is attributed to Giovanni Antonio Scopoli, who referred to it as Phleum autumnale in the second edition of his book, Flora Carniolica, which was published in 1771. Friedrich Wilhelm Schultz gave the species its current name, Sesleria autumnalis in his book Archives de Flore.[7]

The species has been referred to by several heterotypic synonyms, including: Sesleria elongata, Aira alba, and Sesleria argentea var. elongata.[8]

Description

Sesleria autumnalis is a perennial. Its blades are phyllotactic and overhanging, with v-shaped cross sections. In the autumn it changes in color, from light-green to a yellowish brown. It flowers in late summer, when spikelets grow in groups of three on the end of leafless stems.[9][10]

Distribution and habitat

In its natural habitat, S. autumnalis is often found in wooded regions and grassy or sparsely covered areas.[11] The species is common in the Balkan Peninsula and on the calcite mountains of the eastern Alps.[12]
