Culms | cespitose, 9–35 cm. |
loosely cespitose, light green, 15–25 cm. |
Leaves | basal leaves 6–11.5 cm × 1.5–4 mm, apex not callous, sparingly ciliate. |
sheaths dull brown-gray at base, becoming green distally, throats hairless; basal leaves flat toward base, channeled toward apex, 4–16 cm × 3–8 mm, apex abruptly pointed, callous, glabrous. |
Inflorescences | umbellate-paniculate; glomerules 4–30 (each with 9–24 flowers), central glomerules sessile or nearly sessile, cylindric, 6–10 × 4 mm; branches straight, erect, to 3 cm; proximal inflorescence bract conspicuous, leaflike, equal to much longer than inflorescence; bracts clear, sometimes variegated with purple; bracteole margins dentate to lacerate. |
asymmetric in appearance; glomerules (1–)2–5, central glomerules sessile or nearly sessile, 3–9 × 2.5–6 mm; capillary branches 2–8, arched in 1 direction, to 3.5 cm; proximal inflorescence bract bladeless. |
Flowers | tepals clear to straw-colored throughout or centers brown with clear margins and apex, 1.5–2.6 mm; outer whorl exceeding inner whorl, (outer whorl apex awned); anthers equaling to 1.5 times filament length. |
tepals brownish translucent (apex lacerate to entire), 2–3 mm, apex lacerate to entire; anthers equal to or exceeding filaments. |
Capsules | light or dark reddish, shining, spheric, usually equaling inner tepal whorl. |
light chestnut brown, broadly 3-angled, shorter than tepals. |
Seeds | translucent brown, ellipsoid, 0.7–1 mm; caruncle 0.2–0.3 mm. |
most failing to mature, brown (with few hairs present), 3-angled, 0.9–1.1 mm, few hairs present; caruncle barely visible. |

Discussion | Basal leaves of Luzula pallidula are sparingly ciliate. For discussion of the change of the widely known name for this species, see J. Kirschner (1990). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Luzula kjellmaniana has light green culms, sheath throats essentially without hairs, and glabrous basal leaves that are flat toward the base and channeled toward the apex (the apex is abruptly pointed). Most seeds fail to mature. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
