Marantaceae Major Species
qiazhan English name: Marantaceae
Sub Title:
Marantaceae, the prayer plant or arrowroot family (order Zingiberales), composed of about 31 genera and about 550 species. Members of the family are native to moist or swampy tropical forests, particularly in the Americas but also in Africa and Asia. Several species are cultivated as ornamentals or as a source of edible starch.
Physical description
Marantaceae members are largely rhizomatous perennial herbs. They vary from plants with slender, reedlike stalks to leafy spreading or dense bushes nearly 2 metres (about 6.5 feet) high. The petioles (leaf stalks) have a sheathed base, and the simple leaves usually are arranged in two rows. The asymmetrical flowers are borne characteristically in mirror image pairs. The fruit commonly is a berry or a capsule.
The genus Maranta has 40–50 members, which are native to Central and South America and the West Indies. The smooth white rhizomes (underground stems) of some species, such as Maranta arundinacea, furnish the starch known as arrowroot. Other members of the family are popular ornamentals, such as the prayer plant (M. leuconeura).
The number of species of the genus Calathea is contentious, with some taxonomists placing the large genus Goeppertia in Calathea. The leaves of some species are used in basket weaving and for wrapping food. Several Calathea species produce wax, and some have edible flowers and tubers. A number are cultivated as houseplants for their striking patterned foliage.
Other houseplants and ornamentals include the water canna (Thalia dealbata), Stromanthe sanguinea, and various members of Ctenanthe.
Murta, or Indian matcane (Schumannianthus dichotomus), is used traditionally for bed mats and baskets in parts of south Asia.
