Descriptions
Elymus tenuis (Buchanan) Á.Löve & Connor
Prostrate flat, bronze-leaved stoloniferous ope n grass, rooting and shooting from nodes on stolons; branching extravaginal; upper culm internode greatly elongating after anthesis and the long weak culm trails along the ground. Leaf-sheath 5–7 cm, glabrous or sometimes retrorsely pilose. Ligule 0.25–0.3 mm, very finely ciliate. Collar glabrous, curved and thickened. Auricles ± 1 mm or smaller, clasping, with 1–2 long hairs. Leaf-blade 10–15 cm × 2 mm, bronzed, flat sometimes ± involute, abaxially glabrous, smooth, nerves evident, adaxially with short antrorse prickle teeth; margins prickle-toothed. Culm to 2 m, slender, trailing along ground, upper internode elongating after flowering sometimes reaching 1.5 m. Inflorescence 10–15 cm, of up to 15 spikelets. Spikelets 25–40 mm, of 6–8 florets. Glumes 9–15 mm, produced into barbed awn up to 3 mm, 3-nerved, keeled; margins shortly toothed. Lemma 6–10 mm, glabrous except for prickles on central nerve, near bifid apex and on margins below; awn 15–35 mm. Palea 7–10 mm, apex pointed and bifid. Rachilla 1.5–2.5 mm short hairy. Callus 0.5 mm, shortly hair surrounded. Lodicules 1.5– 1.7 mm, linear, irregularly hair tipped. Anthers 2– 3 mm, yellow. Gynoecium: ovary 1.25–1.5 mm; stigma-styles 2–2.5 mm. Caryopsis 4.5–5 mm, embryo 1 mm.
