Festuca loricata
HABIT Perennial; caespitose. Culms erect; 50–80 cm long; 1 -noded. Culm-internodes smooth. Leaf-sheaths tubular for much of their length; smooth, or antrorsely scabrous; glabrous on surface. Ligule a ciliolate membrane; 0.5 mm long. Leaf-blades conduplicate; 10–35 cm long; 2–3 mm wide; coriaceous; stiff. Leaf-blade surface puberulous; hairy adaxially. Leaf-blade apex obtuse, or abruptly acute.
INFLORESCENCE Inflorescence a panicle.
Panicle open; ovate; 17–25 cm long. Primary panicle branches ascending, or spreading; 5–11 cm long. Panicle branches smooth, or scaberulous.
Spikelets solitary. Fertile spikelets pedicelled. Pedicels smooth, or scaberulous.
FERTILE SPIKELETS Spikelets comprising 4–5 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 10–12 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes smooth, or scaberulous.
GLUMES Glumes persistent; similar; subequal in width; shorter than spikelet. Lower glume lanceolate; 4.5–5.3 mm long; 0.75–0.9 length of upper glume; chartaceous; without keels; 1 -veined. Lower glume primary vein smooth, or scaberulous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 5–7 mm long; 0.8–1 length of adjacent fertile lemma; chartaceous; without keels; 3 -veined. Upper glume primary vein smooth, or scaberulous. Upper glume lateral veins obscure. Upper glume apex acute.
FLORETS Fertile lemma oblong; 6–7 mm long; chartaceous; without keel; 5 -veined. Lemma surface glabrous, or puberulous; hairy above. Lemma apex acute; awned; 1 -awned. Principal lemma awn 0.5–1 mm long overall. Palea 2 -veined. Palea keels scabrous. Palea surface puberulous. Apical sterile florets resembling fertile though underdeveloped.
FLOWER Lodicules 2. Anthers 3; 2.5–3 mm long. Ovary glabrous.
FRUIT Caryopsis with adherent pericarp. Hilum linear.
DISTRIBUTION South America: western South America.
NOTES Poeae. Tovar 1995.
