Lepidosperma viscidum
R.Br. Sticky Sword-sedgeClump-forming perennial with short rhizome. Culms rigid, erect, flat or with one surface slightly convex, glabrous, smooth, 35–60 cm high, 2.5–9 mm wide; margins scabrous, viscid (yellowish, turning red) and often ciliate. Leaf-blades similar in form and length to culms, 2–7 mm wide; sheaths straw-coloured or rarely reddish near apex, dark brown to blackish at base, ± viscid, shining. Inflorescence oblong to ovate in outline, erect, occasionally viscid, 7–22 cm long, 1.5–3 cm diam.; involucral bract shorter than inflorescence. Spikelets numerous, 4–7 mm long; glumes 5 or 6, puberulous near apex or glabrous, red-brown to blackish brown, the 2 lowest empty, shorter than fertile glumes, obtuse to acute, mucronate; fertile glumes 4–6 mm long, long-acute; hypogynous scales 6, pale red-brown, to one-quarter length of nut. Nut narrow-ellipsoid to narrow-ovoid, pale to dark brown, smooth, shining, 2.3–3.0 mm long, 1.2–1.5 mm diam. Flowers spring–summer.

On sandy sites in the north-west where common, scattered in rocky areas in the north and a few areas in the east (e.g. Heyfield district, East Gippsland beyond the Snowy River). Occurs in heaths, woodlands and dry open-forest.
In mallee regions of Victoria there is a form or possibly separate taxon which differs from typical L. viscidum in having less viscid, less scabrous, non-ciliate margins, in having more of the leaf-sheath dark-coloured, and with the culm surface rather like that of L. sieberi. This form occurs also in far south-west NSW and adjacent areas of SA.
