Lolium remotum

HABIT Annual. Culms erect; 23–104 cm long; 3–4 -noded. Leaf-sheaths glabrous on surface. Leaf-sheath auricles absent, or falcate; 1–2 mm long. Ligule an eciliate membrane; 1–2.5 mm long; truncate. Leaf-blades 10–26 cm long; 1–6.5 mm wide. Leaf-blade surface smooth, or scaberulous; rough adaxially. Leaf-blade apex attenuate.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 1; single; bilateral; 20–23 cm long; bearing 3–20 fertile spikelets on each. Rhachis semiterete; 0.5–1.4 mm wide; smooth on margins, or scaberulous on margins. Spikelet packing adaxial; regular; 2 -rowed.

Spikelets appressed; solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 2–10 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 5–16 mm long; 1–5 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 0.8–2 mm long.

GLUMES Glumes one the lower absent or obscure; persistent; shorter than spikelet, or reaching apex of florets, or exceeding apex of florets; similar to fertile lemma in texture. Upper glume lanceolate; 5–16 mm long; 1 length of spikelet; coriaceous; without keels; 3–7 -veined. Upper glume apex obtuse, or acute.

FLORETS Fertile lemma ovate; 3.5–4.5 mm long; 1.2–1.8 mm wide; coriaceous; much thinner above; without keel; 3–7 -veined. Lemma apex erose; obtuse; muticous, or awned; 1 -awned. Principal lemma awn subapical; 0–10 mm long overall. Palea 1 length of lemma. Palea keels smooth, or scaberulous; adorned above. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Anthers 3; 1.6–2.2 mm long. Ovary glabrous.

FRUIT Caryopsis with adherent pericarp; oblong, or ovoid; 3.2–4.5 mm long. Hilum linear.

DISTRIBUTION Europe: eastern. Africa: north and Macaronesia. Asia-temperate: Siberia, Soviet far east, and China. Australasia: Australia. South America: southern South America.
