|discussion=<p>A polymorphic yet remarkably well-defined species, Timmia austriaca has the most well-delimited sheath of all Timmia taxa, with an abrupt change in color and sharp angle at the limb-sheath transition, and it is the only taxon where the costa widens slightly just at the limb-sheath transition. Its distinct habit and leaf angularity, dioicous sexuality, non-appendiculate endostome cilia, and orange sheaths separate it from T. megapolitana, while its habit, leaf angularity, and non-deciduous leaves will separate it from T. norvegica and T. sibirica. The perigonial leaves are short and broad, consisting mostly of sheath.</p>
