Note the difference in the two images above. The upper image has numerous basal leaves at the time the flower emerges. The lower image has none, thus the change in species name.
Most Alabamians are apt to call it Cahaba Lily due to its large populations in the shoals of the Cahaba River in Central Alabama. The same flower is also found on other streams in Alabama, Georgia, South Carolina and parts of North Carolina, where it's known as the Shoal Lily or Shoals spider-lily. In fact, this lily was first observed by naturalist William Bartram in 1783 in the Savannah River near Augusta, Ga. Whatever the name, these unique aquatic plants require clean, swift water and rocky shoals to thrive. When they bloom in May and June (usually between Mother's Day and Father's Day) each year, thousands of people make pilgrimages to canoe or wade into Alabama's streams to take in a spectacular panorama. -- "Rivers in Bloom" by David Haynes.
