The importance of pollen morphology has long been recognized and applied by the paleobotanist (Stone 1963). However, the recent use of pollen as a taxonomic character by systematists has simulated greater interest and research in the area of palynology (Graham 1963).

Several investigators have found pollen to be of significant taxonomic value while others have not. Xavier and Rogers (1963) were able to construct a key to the species of Linum by using characteristics of the pollen alone while Stern (1962) noted interspecific differences in the surface characteristics of pollen grains of all but two species of Dicentra.

This current paper is the result of an investigation of the pollen morphology in the Solanaceae (Nightshade family) that occur in Michigan. No intensive survey of the pollen in this economically important family of plants has been done to date. Erdtman (1952) described the pollen of some species of the Solanaceae, but only a few of them were found in Michigan.
