Improved Meyer
By the mid 1940s the Meyer lemon had become widely grown in California. However, at that time it was discovered that a majority of the Meyer lemon trees being cloned were symptomless carriers of the Citrus tristeza virus, a virus which had killed millions of citrus trees all over the world and rendered other millions useless for production. After this finding, most of the Meyer lemon trees in the United States were destroyed to save other citrus trees.
A virus-free selection was found in the 1950s by Don Dillon of the California company Four Winds Growers, and was later certified and released in 1975 by the University of California as the 'Improved Meyer lemon' — Citrus × meyeri 'Improved'.

—Henry David Thoreau (1817–1862)
“... the separation of church and state means separation—absolute and eternal—or it means nothing.”
