The Marantaceae are a family, the arrowroot family, of flowering plants known for its large starchy rhizomes. It is sometimes called the prayer-plant family. Combined morphological and DNA phylogenetic analyses indicate the family originated in Africa, although this is not the center of its extant diversity.
