Plants acaulescent, cespitose; rosettes from vertical, subterranean, branched caudices. Leaf blades stiff, wiry, concavo-convex, 80–130 cm × 4–6 mm, not glaucous; margins entire or remotely serrulate, with widely separated, noncartilaginous teeth; apex lacerate. Scape 0.5–2 dm. Inflorescences paniculate, usually conspicuously tinged purple, 3.5–7.5 dm × 10–20 cm, held partially within rosettes; main rachis and divisions slender, flexible; bracts mostly persistent, to 30 cm, apex curled; bractlets erose, 1.5–3 mm, margins hyaline. Flowers: tepals 1.9–3.2 mm; fertile stamens: filaments 0.9–1.3 mm, anthers 0.7–0.9 mm; infertile stamens: filaments 0.5–0.7 mm, anthers 0.4–0.5 mm; fruiting pedicel erect, slender, articulate near middle, not noticeably dilated, proximal to joint to 1.5 mm, distal to joint to 2.5 mm. Capsules firm-walled, inflated, 3–4 × 4.3–5.5 mm. Seeds closely invested in capsules, rounded, bursting ovary walls, 3–4 mm diam.
Phenology: Flowering late spring–early summer.
Habitat: Rocky limestone slopes or sandy soils, in grasslands
Elevation: 1100–1400 m
Discussion
Nolina micrantha is similar to N. texana except for the purple pigment throughout its inflorescences, later flowering dates, and less robust habit.
Selected References
