Much like no 6 [Solanum rostratum Dunal]; stellate-hairy in the infl and also glandular-villous; lvs to 2 dm, stellate-hairy, deeply and irregularly pinnatifid, the segments coarsely toothed or shallowly lobed; cor pale violet or blue, 3 cm wide; anthers yellow, equal; 2n=24. Native of S. Amer., established as a weed in s. U.S., and often adventive in waste places along the coast in our range. S. citrullifolium A. Braun, a related sp. mainly of Mex. and Tex., has been reported, perhaps mistakenly, from our range. It has unequal anthers, one of them much the longer, outcurved, and violet.
