This species was described in 1953 on the basis of a specimen that had been collected in 1948 at the foot of the western slope of Sexton Mountain in northwestern Josephine County, Oregon, USA. [1]
The Sexton Mountain Mariposa Lily was never again since and is considered extinct now, it is thought to have vanished due to the construction of the Interstate 5, the main Interstate Highway on the west coast of the USA.
