Discussion | Solanum torvum is listed by the United States federal government and several states as a noxious weed. It is occasional to rare in peninsular Florida and could possibly become invasive elsewhere in subtropical climates. The green fruits are used in Asian and West Indian cuisine, often as an addition to soups and curries. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Solanum nitidibaccatum has often been confused with and misidentified as S. sarrachoides, which has a much longer fruiting calyx that nearly covers the mature berry. Solanum nitidibaccatum also differs from S. sarrachoides in its smaller leaves, larger number of flowers per inflorescence (four to eight versus three or four in S. sarrachoides), and fruits with usually two or three sclerotic granules (versus four to six in S. sarrachoides). Most references to Solanum sarrachoides in North American floras are actually S. nitidibaccatum. Solanum nitidibaccatum has also been confused with S. villosum Miller (R. L. McGregor 1986). J. M. Edmonds (1986) regarded S. nitidibaccatum as a variety of S. physalifolium, but the two taxa are now recognized as distinct species, with S. physalifolium restricted to South America. The name S. physalifolium, however, has been used for S. nitidibaccatum in a number of North American floras. Solanum nitidibaccatum is currently considered to be native to both North and South America. It is a common weed in cultivated fields in the Great Plains, Pacific Northwest, and adjacent parts of Canada. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
