Solanum triflorum Nutt., a newly naturalized species of Solanum in China

Solanum triflorum Nutt. (Solanaceae) is reported as a newly recorded species in China. It is a distinctive species with prostrate habit, fleshy and usually pinnatifid leaves, deeply stellate flowers with long, thin anthers, and inflorescences with (usually) a small leaflike bracteole at the apex. The species is significantly different from other species of the genus Solanum in China. The species is native to the Americas with an amphitropical distribution between temperate South and North America. Introduced outside its native range in Europe, South Africa, and Australia, the species was recently found to have naturalized in the Inner Mongolia Autonomous Region of China.
