Alocasia flabellifera

A massive New Guinea Alocasia described by Alistair Hay in 1991, with a thick decumbent stem, petioles to 1.4 m and near-vertical leaf blades around 60 cm long. Unlike most of the genus it grows in very open, wet, disturbed sites, so it wants more light than a typical forest-floor Alocasia and a lot of heat and room.
