Botanists believe that this relatively new lemon-family member is really a cross between a lemon and an orange. Meyer lemons have a a rounder shape and smoother skin than common commercial lemons. Their color ranges from deep yellow to yellow-orange. The aromatic juice is sweeter and less acidic than that of regular lemons, making it possible to actually eat the lemon as is. Meyer lemons are named after F.N. Meyer who imported them from China where it's been grown for centuries.
