Agrostis personata Edgar
Lax, slender tufts 6.5-30-(60) cm, with delicate panicles equalling or overtopping the usually soft flaccid leaves; branching extravaginal. Leaf-sheath membranous, light green to light brown; lower sheaths often with minute retrorse prickle-teeth or hairs, upper sheaths glabrous. Ligule 0.8-2 mm, truncate to ± obtuse, slightly erose, abaxially finely scabrid. Leaf-blade 2-8 cm × 0.5-1.5-(3) mm, flat, or folded and inrolled at margins, abaxially smooth, or sometimes scabrid, especially towards tip and on uppermost culm-leaves, adaxially ciliate-scabrid on ribs; margins sparsely scabrid, occasionally almost smooth, tip acute, scabrid. Culm usually geniculate at base or erect, internodes glabrous. Panicle (2)-4.5-8.5-(16) cm, ovate-lanceolate to pyramidal with filiform branches naked below and spreading widely at maturity; rachis, branches and pedicels sparsely scabrid. Spikelets c. 2-2.5-(3) mm, purplish green. Glumes subequal, acute, with greenish central portion and wide, colourless to purplish margins scabrid near tip; lower narrow-lanceolate, keel scabrid in upper ⅔, upper ovate-lanceolate, keel scabrid in upper ⅓ to ½. Lemma 1.4-2-(2.2) mm, glabrous, 5-nerved, ovate-oblong, truncate, ± denticulate, awnless or with delicate awn 1-3 mm, inserted at c. midpoint to c. upper ⅓ of lemma. Palea 0.3-0.6 mm, orbicular. Lodicules 0.3-0.6 mm, = or usually > palea. Callus with tufts of minute hairs. Anthers 0.4-0.7-(0.9) mm. Caryopsis 1-1.5 × 0.4-0.6 mm. 2n= 42.

Lax, slender tufts 6.5-30-(60) cm tall, with delicate panicles equalling or overtopping the usually soft, flaccid leaves; branching extravaginal. Sheaths membranous, light green to light brown, lower sheaths often minutely ciliate-scabrous, upper sheaths glabrous; ligule 0.8-2 mm, truncate to ± obtuse, slightly erose, abaxially finely scabrous; lamina 2- 8 cm × 0.5-1.5-(3) mm, flat, or folded and inrolled at margins, abaxially smooth, or sometimes scabrous, especially towards tip and on uppermost culm-leaves, adaxially ciliate-scabrous along nerves, margins sparsely scabrous, occasionally almost smooth, tip acute, scabrous. Culms usually geniculate at base or erect, smooth. Panicle (2)-4.5-8.5-(16) cm long, ovate-lanceolate to pyramidal with filiform branchlets bare at base and spreading widely at maturity; rachis, branchlets, and pedicels sparsely scabrous. Spikelets c. 2-2.5 mm, rarely to 3 mm, purplish green. Glumes subequal, acute, with greenish central portion and wide, colourless to purplish margins, keel scabrous above, margins scabrous near tip; lower glume narrow-lanceolate, keel scabrous in upper 2/3, upper glume ovate-lanceolate, keel scabrous in upper 1/3 to ½. Lemma 1.4-2-(2.2) mm, smooth, glabrous, 5-nerved, ovate-oblong, truncate, ± denticulate, awnless or with delicate awn 1-3 mm, inserted just above mid point or higher, to c. upper 1/3 of lemma. Palea 0.3-0.6 mm, orbicular. Lodicules 0.3-0.6 mm, = or usually > palea. Callus with tufts of min ute hairs. Anthers 0.4-0.7-(0.9) mm. Caryopsis 1-1.5 × 0.4- 0.6 mm.
