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.[2]
Description
The plants usually have underground rhizomes or tubers. The leaves are arranged in two rows with the petioles having a sheathing base. The leaf blade is narrow or broad with pinnate veins running parallel to the midrib. The petiole may be winged, and swollen into a pulvinus at the base. The inflorescence is a spike or panicle, enclosed by spathe-like bracts. The flowers are small and often inconspicuous, irregular, and bisexual, usually with an outer three free sepals and an inner series of three petaloid-like segments, tube-like in appearance. The fruit is either fleshy or a loculicidal capsule.
Taxonomy
The APG II system, of 2003 (unchanged from the APG system, 1998), also recognizes this family, and assigns it to the order Zingiberales in the clade commelinids in the monocots. The Marantaceae are considered the most derived family in this group due to the extreme reduction in both stamens and carpels.
The family consists of 29 genera with about 570 known species,[3] found in the tropical areas of the world except in Australia. The biggest concentration is in the Americas, with seven genera in Africa, and six in Asia.

Phytochemistry
Rosmarinic acid can be found in plants in the family Marantaceae such as species in the genera Maranta (Maranta leuconeura, Maranta depressa) and Thalia (Thalia geniculata).[5]
Uses
The most well-known species in the family is arrowroot (Maranta arundinacea), a plant of the Caribbean, grown in parts of the Caribbean, Australasia, and sub-Saharan Africa for its easily digestible starch known as arrowroot. It is grown commercially in the West Indies and tropical Americas.
Several species of genus Calathea are grown as houseplants for their large ornamental leaves, which are variegated in shades of green, white, and pink. Other genera grown for houseplants includes Stromanthe and Maranta.
Calathea lutea has tough, durable leaves used to make waterproof baskets, and in the Caribbean and Central America, its leaves are used for roofing. Two Mexican species - C. macrosepala and C. violacea - have flowers that are cooked and used as vegetables. C. allouia or leren, from the West Indies and tropical America, is known as sweet corn root for its edible tuber.
Schumannianthus dichotomus is used for weaving mats to use on floors and beds.
