Calathea allouga

Calathea allouga Steud. (1840) is an old name with no records of its own; it appears to be a spelling variant of Calathea allouia, now Goeppertia allouia, the Guinea arrowroot or lerén grown for its crisp edible tubers in tropical America and the Caribbean. The profile below assumes that identity.
