|discussion=<p><i>Acrachne</i> has four species, all of which are native to the Eastern Hemisphere. One species, <i>Acrachne racemosa</i>, which is widely distributed in the tropics, was recently found in southern California. The genus resembles <i>Eleusine</i> and <i>Dactyloctenium</i> in its fruits and ornamented seeds, but differs from both in its mode of disarticulation.</p>
