If one considers behavior in the field, ecology, and geography in conjunction with morphologic characters, there is little doubt that M. capillaris, M. expansa, and M. sericea are biological species. Distribution and typical habitat are different for the three species, but M. capillaris can be found growing with or in proximity to each of the other two. In such situations, the two taxa present are readily distinguishable at a glance, and there is no evidence of intermediates or hybrids, per Weakley's Flora (2022)
