From Flora of Indiana (1940) by Charles C. Deam
This species prefers a very sandy or sandy, clay soil. I have infrequently found it in a few of the southern counties. The reports from Lake, Marshall, and Putnam Counties were of specimens collected in railroad ballast and may have been introduced. The seed of all our species are mealy-pubescent. The pubescence is easily detached in this species while in the preceding species [Strophostyles umbellata] it is persistent.
