Frequent in every county of the state, although the map shows no specimens from a few central counties that have not been botanized. This is a woodland species and is found in dry soil on the crests of ridges, on wooded slopes, and on the high banks of streams. I am citing my [Deam] no. 54623 as exceptional. In 1933 I found this plant in a sandy black and white oak woods on the northeastern side of Simonton Lake, Elkhart County. In 1935 I again collected it under my no. 56864. This form covered an area about 50 feet wide and 125 feet long. It was associated with a thick stand of Solidago caesia which covered an acre or more. The leaves of this form are on distinct short petioles, the base rounded, the teeth of the margin fewer and wide apart, the blades distinctly much longer than in the typical form. It has been suggested to me by a student of the genus as a possible hybrid of Solidago caesia and Solidago ulmifolia.
