Puccinellia macquariensis (Cheeseman) Allan & Jansen
Perennial tufts, 4-25 cm, with culms completely enclosed by leaf-sheaths and panicles overtopped by the soft, dull green leaves; branching intravaginal. Leaf-sheaths smooth, hyaline, whitish green, much wider than leaf-blades; ligule 0.7—1.5 mm, erose; leaf-blades 2—8 cm × c. 1 mm, flat or folded, sometimes with inrolled margins, smooth throughout, tip obtuse. Culms erect, or geniculate at base. Panicle 1.5-6 × 0.5—1 cm, lanceolate, with few, short, erect, sharply angled, smooth to sparsely scabrous branches. Spikelets 4—6.5—(8) mm, 3—5-flowered, pale green, sometimes purplish. Glumes ± unequal, elliptic-ovate to elliptic-oblong, obtuse; lower glume 1.6-2.6 mm, 1-3-nerved; upper glume 2-3.5 mm, 3— (5)-nerved. Lemma 3-4 mm, 5-nerved, elliptic-ovate to elliptic-oblong, glabrous or with a few hairs at base and on nerves near base, midnerve almost reaching obtuse tip. Palea ± = lemma, keels conspicuously long-ciliate at midway with shorter prickle teeth in upper ¼, and glabrous in lower ¼, tip truncate to bifid with the keels not excurrent. Rachilla 0.7-1.2 mm. Anthers 0.4-0.9 mm. Caryopsis 1.5-1.7 × 0.6-0.8 mm. 2n = 28. Endemic.

Perennial tufts, 4-25 cm, with culms ± hidden by leaf-sheaths and panicles overtopped by the soft, dull green leaves; branching intravaginal. Leaf-sheath glabrous, hyaline, whitish green, much wider than leaf-blade. Ligule 0.7-1.5 mm, erose. Leaf-blade 2-8 cm ×c. 1 mm, flat or folded, sometimes with inrolled margins, glabrous throughout, tip obtuse. Culm erect, or geniculate at base, internodes glabrous. Panicle 1.5-6 × 0.5-1 cm, lanceolate; branches few, short, erect, sharply angled, smooth to sparsely scabrid. Spikelets 4-6.5-(8) mm, 3-5-flowered, pale green, sometimes purplish. Glumes ± unequal, elliptic-ovate to elliptic-oblong, obtuse; lower 1.6-2.6 mm, 1-3-nerved, upper 2-3.5 mm, 3-(5)-nerved. Lemma 3-4 mm, 5-nerved, elliptic-ovate to elliptic-oblong, glabrous or with a few hairs at base and on nerves near base, midnerve almost reaching obtuse apex.
