Sexton Mountain Mariposa Lily (Calochortus indecorus)

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.

Calochortus monanthus Ownbey

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.
