One species, Acrachne racemosa, which is widely distributed in the tropics, was recently found in southern California. The genus resembles Eleusine and Dactyloctenium in its fruits and ornamented seeds, but differs from both in its mode of disarticulation.</p> |tables= |references={{Treatment/Reference |id=clifford1996a |text=Clifford, H.T. 1996.
