Schedonorus
See list of 3 species in this genusSchedonorus has traditionally been included in Festuca. However, many morphological features unite this genus with Lolium rather than Festuca (e.g., auricle morphology, ovary indumentum, style attachment, leaf blade morphology). Reference: Darbyshire (2007).
-
1a. Lemma awns 10–18 mm long; leaf blades (4–) 6–18 mm wide
-
1b. Lemma awns absent or up to 2 (–4) mm long; leaf blades 2–10 (–12) mm wide
-
2a. Auricles of leaves eciliate; basal sheaths brown to red-brown, soon shredding into many fibers; internodes of the rachilla smooth or nearly so; upper glumes 3–5 mm long
-
2b. Auricles of leaves ciliate (often sparsely so) [Fig. 266]; basal sheaths white-brown to light brown, persistent, not soon shredding into fibers; internodes of the rachilla antrorsely scabrous; upper glumes 4.5–7 (–9) mm long
