Because it somewhat resembles the sour orange, the myrtle-leaf orange (chinotto of Italy, chinois of France) is commonly considered to be a botanical variety of C. aurantium L. Indeed, the presumption is that the myrtle-leaf orange originated as a mutation from the sour orange. The differences are sufficiently great and the degree of variation exhibited so wide, however, as to appear to justify separate species standing (The Citrus Industry Vol. 1 (1967))
