--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>without deciduous distal leaves. <b>Leaf</b> apex acute (but with terminal 4–5 cells often truncated); costa subpercurrent; sheath orange but appearing red when still on stem; limbs green, pellucid; limb-sheath transition abrupt, sharply angled; limb margins strongly dentate in distal 1/3–1/2, less dentate to entire proximally, occasionally crenulate or entire throughout; limb lamina cells 8–14(–16) × 8–12(–13) µm, with low conical or rounded mamillae on the adaxial surface, abaxial surface smooth; distal sheath lamina cells smooth or with 1–6(–8) large round, often verrucose papillae over the abaxial surfaces of lumen; cells at leaf insertion not hyaline and fragile; abaxial surface of costa limb smooth, toothed or papillose near apex, adaxial cells with conical or rounded mamillae. <b>Sexual</b> condition dioicous; perichaetial leaves more strongly dentate than vegetative leaves, sheath up to half the leaf length. <b>Calyptra</b> without longitudinal split, not persistent on seta. <b>Capsule</b> spirally plicate (even when young and operculate); exothecial cell walls sinuose; stomata mostly on the neck; endostome cilia without appendiculations on the interior surfaces.</span><!--

|discussion=<p>A polymorphic yet remarkably well-defined species, <i>Timmia austriaca</i> has the most well-delimited sheath of all <i>Timmia</i> 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 <i>T. megapolitana</i>, while its habit, leaf angularity, and non-deciduous leaves will separate it from <i>T. norvegica</i> and <i>T. sibirica</i>. The perigonial leaves are short and broad, consisting mostly of sheath.</p>
