Discussion | Solanum furcatum is found in coastal environments in the western United States. M. Nee (1993) stated that the name S. gayanum (J. Remy) F. Philippi has been misapplied to plants of S. furcatum, but no basis can be found for this assertion and the two species are morphologically very different. Solanum gayanum, a synonym of S. crispum Ruiz & Pavon, and native to Chile, is cultivated and perhaps naturalized in San Francisco, California (P. A. Munz 1968). Solanum furcatum can be distinguished from the similar and sympatric S. douglasii by its usually forked inflorescences and fruits with usually more than ten sclerotic granules. A distinctive character of S. furcatum is the long style that is about twice the length of the anthers. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Many accounts of Solanum sarrachoides in North America actually refer either to S. nitidibaccatum or to a mixture of the two species. In North America, S. sarrachoides is much less widespread and common than S. nitidibaccatum. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
