Inflorescences racemose, 1(-2)-flowered; proximal 2 flowers, when present, not paired; bracts (2-)3-7(-8) mm. Flowers: tepals (6-)7-10(-13) × 0.9-2.4 mm (chasmogamous flowers), shorter to longer than pedicel, 1.5-2 times as long as ovary; anthers 1.1-2.2 mm; ovary oblanceoloid, (3-)4-5(-6) × 1.5-2.5 mm, densely pilose; pedicel (2-)3-7(-8) mm, equaling or slightly shorter than bracts. Seeds black beneath loose, iridescent, membranous coat, (1.3-)1.4-2 mm, with rounded pebbling. Flowering spring--summer. Mesic to moist pinelands; 0--200 m; Ala., Ark., Fla., Ga., La., Miss., N.C., Okla., S.C., Tex., Va. Although there is a strong tendency for summer flowering in Hypoxis sessilis, in the southern part of its range it will flower at any time of year in response to fire or other disturbances.
