Festuca amblyodes subsp. erectiflora (Pavlov) Tzvelev; F.erectiflora Pavlov. F. violacea var. kaschmiriana Hackel. Subg. Festuca L. sect. Aulaxyer.
Vegetative morphology. Plants stiffly erect. Plants loosely tufted, or turf forming. Plants clumped loosely. Plants with non-flowering shoots more common than flowering shoots. Plants with leaves mostly basal. Plants with tillering leaves over half the length of the culms. Culms 15–30 cm tall. Culms 0.6–0.7 mm wide. Culms strict, erect. Culms internodes glabrous. Culms nodes 1–2. Uppermost culms nodes in mid 1/3 of the culm. Sheaths shorter than the internode (sometimes longer than internoeds). Sheaths glabrous. Sheaths open more than half their length. Sheaths not conspicuous at the base of the plant. Sheaths remaining entire, not conspicuously splitting between the veins. Sheaths, of uppermost culm leaf not inflated. Collars glabrous. Auricles erect swellings. Ligules (0.2–)0.4–0.6 mm long. Ligules membranous. Ligules margins ciliolate. Ligules apices erose, or lacerate. Leaf blades more or less lax. Leaf blades filiform, or linear. Leaf blades conduplicate. Leaf blades 5–15 cm long. Leaf blades adaxial surfaces glabrous, or with trichomes. Leaf blades adaxial surfaces glabrescent. Leaf blades abaxial surfaces glabrous. Flag leaves blades 2.5–3 cm long. Flag leaves blades distinctly shorter than the sheath. Leaf blades 0.3–0.5 mm wide. Leaf blades 0.5–0.6 mm deep. Veins 5. Adaxial to abaxial sclerenchyma strands absent. Abaxial sclerenchyma poorly developed. Abaxial sclerenchyma in narrow or discrete strands. Ribs 5 (central ribs and 4 lateral ribs well defined).
Floral morphology. Inflorescences lanceolate, or broadly lanceolate. Inflorescences loosely open. Inflorescences not nodding. Inflorescences 3–5 cm long. Inflorescences branches 1–2(–4) cm long. Inflorescences lowest internodes 1–1.3 cm long. Inflorescences branches at the lowest nodes 1. 2 fertile spikelets on the longest branches. Inflorescences branches angular in cross section. Inflorescences branches scabrous on the angles. Inflorescences branches vestiture sparse. Pedicels 3–7 mm long. Spikelets aggregated towards the ends of the branches (a few spikelets), or lower half of the branches without spikelets. Spikelets 6–7(–11) mm long. Spikelets 1.3–3 mm wide (before anthesis). Spikelets greenish, or purplish, or brown. Florets 3–4(–5). Glumes membranous. Glumes glabrous. Glumes margins ciliolate (on second glume margins). Glumes margins narrowly membranous (narrowly). Glumes apices accuminate. First glume narrowly lanceolate, or lanceolate. First glume 2–2.8 mm long. First glume 1 nerved. First glume 0.6–0.7 as long as second glume. Second glume narrowly lanceolate, or lanceolate. Second glume 3.4–4.1 mm long. Second glume 3 nerved. Second glume shorter than first lemma. Second glume 0.5–0.6 as long as the spikelets. Rachilla internodes 1.2–1.6 mm long. Rachilla internodes antrorsely scabrous. Rachilla internodes flattened. Lemmas 4.5–6.2 mm long. Lemmas lanceolate. Lemmas membranous. Lemmas rounded on the back. Lemmas veins 5. Lemmas with distinct veins in dorsal view. Lemmas with trichomes. Lemmas punctiform. Lemmas trichomes on the upper portion. Lemmas margins smooth. Lemmas upper margins not membranous. Lemmas apices accuminate. Lemmas apices awns 1–1.5 mm long. Lemmas apices awns much shorter than the lemmas. Paleas 5–5.3 mm long. Paleas 0.4–0.6 mm apart. Paleas equal or subequal to the lemmas. Paleas keels scaberulous, or scabrous. Paleas inter-keel regions puberulent, or punctiform. Lodicules 1 mm long. Anthers 1.8–2.4 mm long. Ovary apices hairy (a few hairs).
