Species

Angiosperms > Poales > Juncaceae > Luzula

Characteristics

Stoloniferous erect or ascending perennial, 25-70 cm high. Lower leaves crowded at the base of the stem; the higher ones more remote and gradually diminishing in size; all leaves linear from a sheathing base, flat, with a much tapering apex, terminated by a very short, shortly triangular not thickened point, along the smooth margins and often also on the surfaces with a few scattered long very fine white hairs, the larger leaves 6-12 cm by 6-12 mm. Flowers in an elongate very lax panicle, the lower branches of which arise from the higher leaf-axils; branches often nodding or drooping; flowers for the greater part solitary on pedicels 4-12 mm long, for the rest shortly pedicelled or subsessile. Perianth 2-2½ mm long. Tepals narrowly ovate-lanceolate, very acute. Stamens 6, slightly shorter than the perianth; filaments very thin, ± 1 ¼ mm long; anthers oblong, ½-¾ mm. Capsule about as long as the perianth, broadly ellipsoid-obovoid, trigonous, crowned by the style-base. Seeds usually 3, erect, oblong or oblong-ob-ovoid, brown, faintly reticulate-ribbed, on the rounded top with a minute pale elaiosome, 1 ¼-l ½ mm long.

Plants 20--70 cm tall. Stolons short. Stems terete, 1--6 mm in diam. Basal leaves several, basal one smaller than others and usually withered and persistent at anthesis. Cauline leaves 3--5; leaf blade lanceolate to narrowly so, flat, 5--18 cm × 2--25 mm, margin sparsely long pilose especially near juncture with leaf sheath, apex chestnut brown, acuminate. Inflorescence borne in axils of 2 or 3 apical cauline leaves, a decompound, corymbose cyme; bracts ovate-lanceolate to lanceolate, 1.5--3(--6) mm, margin sparsely ciliate. Flower solitary; pedicel divaricate, to 3 cm, unequal; bracteoles 2, ovate, 1--1.5 × 0.6--0.9 mm, margin lacerate or pilose. Perianth segments yellowish green to pale brown or reddish brown to dark brown, ovate-lanceolate, 2--2.5 × 0.8--1.2 mm, subequal or inner ones slightly longer than outer, apex mucronate. Filaments 0.8--1 mm; anthers 0.6--0.8 mm. Stigmas 0.8--1.6 mm. Capsule trigonous ovoid, slightly longer than perianth, apex mucronate.
