JUNCACEAE (Luzula)
Lower bract usually 2.0–4.0 cm long, shorter than inflorescence. Inflorescence with one
subsessile and 1–6 pedunculate clusters; peduncles straight, smooth, usually without
secondary branches; longest peduncles (including clusters) 2.0–9.5 cm long. Clusters
±cylindrical, 8–25-flowered; basal flowers of the pedunculate clusters often slightly remote.
Bracteoles 1.6–1.9 mm long, ciliate or fimbriate-ciliate. Tepals pale brown; outer tepals
±equalling or slightly longer than inner ones, 2.4–2.8 mm long, subabruptly narrowing at the
apex. Anthers 0.8–0.9 mm long; filaments c. 0.4 mm long; ovary 0.7–0.8 mm long; style
0.3–0.4 mm long; stigma early deciduous, 0.8–1.0 mm long. Capsules subacuminate,
equalling or shorter than perianth; capsule segments 1.9–2.1 mm long. Seeds oblong-ovoid,
c. 0.9 mm long, 0.6–0.7 mm wide; appendage 0.2–0.3 mm long. 2n=24 [probably 24BL], fide

Rare endemic distinct in having slightly loose clusters at the base of the inflorescence; in
general habit it is similar to L. pallescens.

Perennials usually 15–20 cm tall, densely caespitose; stolons absent; rhizome short; stems erect,
slender. Basal leaves densely to subsparsely ciliate, 2–4 mm wide. Cauline leaves usually 2,
with densely papillose-serrate margin; upper cauline leaves 1.5–4.5 cm long, 2.0–3.0 mm
wide. Lower bract usually 1.2–2.5 cm long, shorter than inflorescence. Inflorescence
composed of 1–2 subsessile and 2–5 pedunculate clusters; peduncles straight or flexuose,
papillose in upper half or papillose throughout, usually without secondary branches; longest
peduncles (including clusters) 2.0–5.5 cm long. Clusters ovoid to hemispherical, 4.5–7.5 ×
5.0–6.5 mm, usually (2–) 4–6 (–8)-flowered; basal flowers of the pedunculate clusters not
remote. Bracteoles 1.0–1.5 mm long, ciliate above. Tepals pale to dark brown; outer tepals
±equalling inner ones, 2.6–3.0 mm long. Stamens 6; anthers (0.5–) 0.7–0.9 mm long;
filaments 0.4–0.6 mm long; ovary 0.7–0.8 mm long; style 0.7–1.0 mm long; stigma 1.7–2.2 mm
long. Capsules obovoid to subglobular, equalling or shorter than perianth; capsule segments
brown, 2.0–2.4 mm long, c. 1.3 mm wide. Seeds ovoid, (0.9–)1.0 mm long, 0.7–0.8 mm
wide; appendage c. 0.3 mm long. 2n=24 [24BL], fide J.Kirschner, Preslia 63: 86 (1991).

Characterized by small, few-flowered, usually hemispherical clusters, papillose peduncles
and relatively short seed appendages. Plants from E Bulgaria and the Sofia vicinity are
±variable in the diagnostic characters, perhaps due to hybridization. In the S Pirin Mtns,
introgression with L. campestris subsp. campestris was observed (J.Kirschner, Preslia 63:
81–112, 1991). The distribution is imperfectly known.
