--><p><i>Micropsis</i> 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, <i>Micropsis</i> is known only from temperate South America. It appears to be monophyletic, with ancestors possibly near Evax or Stuartina Sonder (J. D. Morefield 1992). <i>Micropsis</i> 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).</p>
