The
Restionaceae, also called
restiads and
restios, are a
family of perennial, evergreen rush-like
flowering plants native to the Southern Hemisphere; they vary from 10 cm to 3 m in height. Based on evidence from fossil pollens, the Restionaceae likely originated more than 65 million years ago during the
Late Cretaceous period, when the southern continents were still part of
Gondwana.
