|discussion=<p>Solanum chenopodioides has been introduced sporadically and is occasionally adventive in North America. It is distinctive in having the fruiting peduncles strongly reflexed downward, but is otherwise difficult to distinguish from S. pseudogracile, with which it may be conspecific.</p><!--
--><p>The illegitimate superfluous name Solanum gracile Dunal has often been used for S. chenopodioides (for example, J. K. Small 1913; A. E. Radford et al. 1968). W. G. D’Arcy (1974) included S. gracile (and its replacement name S. ottonis) in the synonymy of S. nigrescens but the taxa are distinct.</p>
