Festuca hartmannii

HABIT Perennial; caespitose. Culms erect; 10–35 cm long. Ligule an eciliate membrane; 0.3 mm long. Leaf-blades filiform; conduplicate; elliptic in section; 5–15 cm long; 1 mm wide; mid-green. Leaf-blade venation comprising 5–7 vascular bundles; with sclerenchyma strands widened to form a discontinuous subepidermal layer, or with continuous uniform subepidermal sclerenchyma layer on the underside. Leaf-blade surface smooth.

INFLORESCENCE Inflorescence a panicle.

Panicle contracted; oblong; 2–6 cm long. Primary panicle branches appressed. Panicle branches scabrous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 3–5 fertile florets; with diminished florets at the apex. Spikelets elliptic, or oblong; laterally compressed; 4.5–7 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; dissimilar; shorter than spikelet. Lower glume lanceolate; 2.2–3 mm long; 0.7–0.8 length of upper glume; chartaceous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 3–4.2 mm long; 0.9 length of adjacent fertile lemma; chartaceous; without keels; 3 -veined. Upper glume apex acute.

FLORETS Fertile lemma oblong; 3.3–4.5 mm long; chartaceous; without keel; 5 -veined. Lemma surface scaberulous; rough above. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn 1–2 mm long overall. Palea 1 length of lemma; 2 -veined. Palea keels scaberulous; adorned above; with 0.33–0.66 of their length adorned. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 2. Anthers 3; 1.4–1.8 mm long. Ovary glabrous.

FRUIT Caryopsis with adherent pericarp. Hilum linear.

DISTRIBUTION Asia-tropical: India.

NOTES Poeae. Fl Pak 1993.
