Single-flowered Mariposa Lily (Calochortus monanthus)

The Single-flowered Mariposa Lily, also known as the Shasta River Mariposa Lily, is known only from the type that was found in 1876 along the Shasta River in Sisiyou County, California, USA.

As its name implies, the species beared a single flower that was pinkish white with chevron-shaped dark red spots above each of the nectar-secreting glands.

There were attempts to relocated the species in 1990, but these were unsuccessful, it is now considered extinct.
