Xanthosoma riedelianum (Xanthosoma riedelianum)
Description
Xanthosoma is a genus of flowering plants in the arum family, Araceae. The genus is native to tropical America but widely cultivated and naturalized in other tropical regions. Several are grown for their starchy corms, an important food staple of tropical regions, known variously as malanga, otoy, otoe, cocoyam (or new cocoyam), tannia, tannier, yaut-a, macabo, ocumo, macal, taioba, dasheen, quequisque, -ape and (in Papua New Guinea) as Singapore taro (taro kongkong). Many other species (including especially X. roseum) are used as ornamental plants, and in popular horticultural literature are known as -ape or elephant ear (from the purported resemblance of the leaf to an elephant's ear), although the latter name is sometimes also applied to members with similar appearance and uses in the closely related genera Caladium, Colocasia (i.e., taro), and Alocasia. The leaves of most Xanthosoma species are 40-200 cm long, sagittate (arrowhead-shaped) or subdivided into three or as many as 18 segments. Unlike the leaves of Colocasia, those of Xanthosoma are usually not peltate- the upper v-notch extends into the point of attachment of the leaf petiole to the blade.
