Scape 2-10 dm. Inflorescences racemose. Flowers each subtended by 2 subulate, unequal bracts, short-pedicellate; perianth white, yellow, or golden orange, cylindrical, campanulate , or obovoid , abaxial surfaces rough; tepals 6, connate basally; stamens 6, included ; filaments adnate to perianth; anthers oblong-lanceolate, longer than filaments; ovary half inferior with proximal portions of perianth adnate at maturity; style 3-branched at apex. Fruits capsular , 3-locular, beaked . Seeds amber, deeply sulcate , ellipsoid to ovoid , 0.5-0.8 mm, lustrous .

Physical Description

Species Aletris lutea

Leaves 7-18 × 1-2.6 cm; blade bright green, linear to lanceolate. Scape 5-10 dm. Flowers: perianth usually yellow to golden yellow, rarely white, cylindrical, 9-12 mm, more than 2.5 times as long as broad, lobes spreading . Fruits: beaks gradually narrowed distally. 2n = 26. [source]

A white-flowered form of Aletris lutea was described as forma albiflora E. T. Browne. Hybrids of A. lutea × obovata occur commonly in intermixed populations and have pale yellow corollas of intermediate shape (V. I. Sullivan 1973). These hybrids have been named as A. ×tottenii E. T. Browne. [source]
