Micropsis species occur in moist or dry, often sandy or alkaline habitats of Mediterranean to humid temperate climates. Other than a recently discovered population in the flora area, Micropsis is known only from temperate South America. It appears to be monophyletic, with ancestors possibly near Evax or Stuartina Sonder (J. D. Morefield 1992). Micropsis is most easily recognized by bisexual paleae enlarged, ± saccate, usually apically lacerate, often distally gibbous, resembling straitjackets tightly enveloping their florets and cypselae, and pistillate cypselae densely strigose (known in other Filagininae only in Old World Evax and relatives).
