Solanaceae (Potato Family)
Synonym(s): Solanum ptychanthum

A smooth plant with few-flowered, lateral umbels of small, white, star-like, drooping flowers.
This native species, which some authorities claim includes S. americanum, often appears in open areas. Other similar nightshades with small white flowers include the western and Great Plains species Cut-leaved Nightshade (S. triflorum), with deeply dissected leaves, which occurs from the West Coast to Minnesota, Iowa, and Missouri and occasionally eastward, and Hairy Nightshade (S. villosum), with very hairy stems and yellow or red berries, which occurs sporadically from Maine south to Florida.
Some authorities accept the orthographic variant, Solanum ptychanthum.
