Plants (10–) 25–50 (–65) cm tall. Leaves of sterile shoots (when present) to 30 cm long,
c. 5–7 mm wide; cauline leaves usually 4–5, usually (7–) 9–13 cm long, 4–8 (–9) mm wide.
Lower bract herbaceous, usually (2–) 4–8 cm long, ±equalling or shorter than inflorescence.
Inflorescence usually 4–7 × 3–6 cm; main branches long; secondary branches short; flowers
usually in 2–3 (–5)-flowered clusters, some borne singly. Tepals (2.0–) 2.5–2.8 (–3.3) mm
long. Anthers 0.7–0.8 (–1.0) mm long, 2–3 times longer than filaments; filaments 0.3–0.4 mm
long; style 0.6–0.7 mm long; stigmas 1.0–2.0 mm long.
S Europe, confined to Balkan Peninsula: Albania, Bulgaria, F.Y.R. Macedonia and Greece.

MACEDONIA: Shar Planina, above Shtrbtse, 1900 m, K.Vandas (PR).
Very variable in size, tepal length and leaf width. In many characters it overlaps with those
of subsp. obscura. Plants intermediate between subsp. obscura and subsp. deflexa occur in
N Bulgaria; plants from Greece probably are similar.
Presumed hybrids
Luzula parviflora (Ehrh.) Desv. × L. piperi (Coville) M.E.Jones
Reputed hybrid, fide L.Hämet-Ahti, Ann. Bot. Fenn. 8: 378 (1971). The only specimen
