Here are the list of the plants - specifically these Alocasia type which is commonly known as Jewel Alocasia which is quite sensitive and highly sought after considering them as a rare plants.
This is my Jewel Alocasia Collection which I find them more of the sensitive & slow growing type in comparison the the Elephant Ear type Alocasia which are more hardy and easily grown outdoor with direct sun & rain.
