Morphology General Habit
Perennial herb from a thick rhizome up to 6 cm long, 2.5 cm in diameter, with spreading fleshy yellowish roots 1.5–3 mm in diameter.
Morphology Leaves
Leaves in a basal rosette, lanceolate to linear-lanceolate, 30–150 cm long, 1–3.5 cm wide towards the base, 3-angled and channelled, the outer leaves reduced to membranous sheaths up to 5.5 cm long.
