This interesting fruit, the Meyer lemon, a hybrid of lemon and some sort of orange, has apparently been known in the U.S. since the early 20th century, but I had not heard of it until yesterday. Neither did my wife knew about it. How do you explain that?
The Meyer lemon is named after Frank N. Meyer, a.k.a. Frans Nicholas Meijer (1875-1918), a USDA employee who discovered it in China.

The Meyer lemon is sweeter than an ordinary lemon and has a nice, strong, spicy aroma. I have discovered that its juice mixed with a little bit of Bacardi Gold rum and some tropical fruit juice, such as pineapple, makes a great cocktail.
More info about Frank N. Meyer with photographs and documents from his Asian expeditions are at this USDA site.
