Rytidosperma racemosum (R.Br.) Connor & Edgar APNI*
Synonyms: Austrodanthonia racemosa (R.Br.) H.P.Linder APNI*
Description: Variable, erect, rather slender, caespitose perennial to c. 0.6 m high.
Culms slender, glabrous, smooth, mostly 3-noded. Sheaths striate, more or less glabrous; ligule reduced to very short cilia, 0.25 mm long; blade fine, narrow, usually closely inrolled, 5–15 cm long, shallowly grooved, almost glabrous to more or less pilose, very finely and obsurely scabrous on the inner surface.
Inflorescence much exserted, 5–15 cm long, few- many-flowered, linear, the branches laxly spreading at anthesis when fresh. Spikelets 6–10-flowered, pale greensih to straw coloured, the groupd of florets usually exceeding the glumes. Glumes with membranous margins, 5–7-nerved, 7–16 mm long. Lemmas 3.5–5.5 mm long, linear to oblanceolate when folded, pilose, pale; lateral lobes often broad, narrowing abruptly into fine setae, variable in length, or awnless; central awn much exserted, brown and twisted in the lower part, straight above; palea elliptic, glabrous on the back.
