Beautiful, rare Alocasia Melo, sometimes called "Rhino Skin". This is considered one of the Jewel Alocasias, similar to the dragon scale Alocasias. The leaves are amazing, you'd almost think they are plastic, they are so strong and hardy.
Alocasia Rhino Skin
They grows best in bright, indirect light. Care also requires that the soil be free draining but hold some water. If you are growing this plant as a houseplant, half and half mix of potting soil and orchid soil or perlite will provide the kind of soil anthuriums prefer.
