Croton lindheimeri is very similar to C. capitatus, and the two can sometimes be found growing together in northeastern Texas. Croton lindheimeri can be distinguished by its more ochraceous pubescence on young growth, consistently acute leaf tips, somewhat more elongated pistillate part of the raceme, and pistillate sepal tips that do not recurve after anthesis. Croton lindheimeri was reported from Indiana, adventive on ballast in 1898, and from Kansas based on a single 1883 collection from Miami County, but apparently did not become established in either state.
