PlaceOfPublication Sp. P1. 113. 1753.-FIG. 2.
Description Persistent herb with a short, inconspicuous rhizome, the roots tough and appearing fibrous. Leaves numerous, lanceolate, to 30 cm long, gradually narrowed into the petiole, strongly ribbed with usually 5 parallel veins, glabrous when mature except for the ribs beneath and a dense tuft of whitish hairs at the base of the petiole. Scape slender, longer than leaves, glabrous or pubescent. Flowers in a dense, capitate, globose, or cylindrical spike, the lowermost bracts enlarged to form an involucre, flowering proceeding from the bottom upwards giving the spike a very different appearance at different stages; bracts in the inflorescence cucullate, with a light green midrib and hyaline, often erose margins, broadly ovate with an elongate stipe, 4-7 mm long; sepals 3-3.5 mm long, erose-margined, emarginate apically; corolla lobes 2 mm long; anthers
