Arum palaestinum is a species of flowering herbaceous perennial plant in the family Araceae (also known as black calla, Solomon's lily, Priest's Hood, Noo'ah Loof and kardi) This plant is native to the Levant and other parts of the Mediterranean Basin, and has been naturalized in North America, Europe, and Australia
Arum palaestinum has more than 3 other additional names.
There are 5 other names for it listed, and 5 is certainly more than 3. It's difficult because this is not stated explicitly I guess and has to be calculated, so this confused the system.
