''Solanum ptychanthum'', West Indian nightshade or eastern black nightshade, is an annual or occasionally perennial plant in the Solanaceae (Nightshade) family. It is typically 15–60 cm tall and many branched. The leaves of eastern black nightshade are triangular to elliptic. The stems are circular, and sometimes slightly hairy. The flowers are small, white, and star-shaped, and they occur in small umbels of 5-7. The flowers ripen into glossy, black berries, each 10 mm in diameter and containing between 50 and 100 seeds. The ripened fruits have been shown to be not poisonous in low to moderate amounts,〔Voss, Kenneth A, William J. Chamberlain, and Lucas H. Brennecke. "Subchronic toxicity study of eastern black nightshade (''Solanum ptychanthum'') berries in Sprague-Dawley rats." Journal of Food Safety Vol 13 No. 2, pp. 91-97.〕 however the unripened berries are toxic. The berries are eaten and dispersed by birds. == Nomenclature == The original spelling is “ptychanthum”, from the Greek (ptyche, a fold + anthum, flowered). Some sources mistakenly refer to this plant as S. ptycanthum (without the first 'h'). Also, some sources list ''Solanum americanum'' as a synonym, however it is a misaplication of the name. The Germplasm Resources Information Network lists ''Solanum americanum'' as a synonym of ''S. ptychanthum'', but as S. americanum auct. (i.e. a misapplication of the name), not ''S. americanum'' Mill. Other sites have not make this distinction and the two have become confused.〔http://www.efloras.org/browse.aspx?flora_id=0&name_str=Solanum+ptycanthum&btnSearch=Search〕
