Micropsis dasycarpa is known in the flora area from one gathering (Victoria County, Gulf Coast prairie with Mimosa strigillosa Torrey & A. Gray, in 1987). For this treatment, I have assumed the Texas population to be a recent introduction; R. Barneby provided evidence that M. dasycarpa could be an overlooked amphitropical native (J. D. Morefield 2004; see also discussion under 101. Psilocarphus).
