About

Alocasia longiloba is a species of flowering plant in the family Araceae. It is the namesake of a species complex. The complex has a widespread distribution; Guangdong, Hainan, and southern Yunnan in China, mainland Southeast Asia, and western and central Malesia.

In the houseplant trade, many of the former species that were subsumed into Alocasia longiloba are now considered types or varieties, these include 'argyrea', 'korthalsii', 'lowii', and 'watsoniana'. The placement and validity of such varieties, and of any potential hybrids and cultivars within the complex is unclear, including 'Jackrabbit' and 'Thibautians'. Similarly, a cross of Alocasia lowii with the kris plant Alocasia sanderiana produced Alocasia × mortfontanensis, which may or may not be the same as the well-known hybrid Alocasia × amazonica, the African mask, formed by crossing A.
