Calochortus bruneaunis is a species of flowering plant in the lily family, and is known by the common name Bruneau mariposa lily.

Description

Calochortus bruneaunis is a perennial herb producing a mostly unbranching stem up to 40 centimeters tall. The leaf at the base of the stem is narrow in shape, reaching 10 to 20 centimeters long and withering away at flowering.

The inflorescence bears 1 to 4 erect bell-shaped flowers. The pointed sepals and larger, rounded petals are white to lilac-tinted in base color. The sepals are marked with a reddish or greenish spot or streak toward their bases and the petals have a greenish streak on the outer surface and a base of yellow, purple, and red coloration on the inner surface.

In 1940 Francis Marion Ownbey described it as a variety of Calochortus nuttallii, but it is an accepted species according to Plants of the World Online. It has one heterotypic synonym, Calochortus discolor, described and named by Anstruther Davidson in 1915.[2]
