Calochortus syntrophus
Callahan's mariposa lily is a rare bulbous wildflower from northern California, found in open rocky oak woodland with moist soil. It is a species, not a commonly grown garden plant, and grows best where its bulb can stay damp in spring and rest dry in summer.
Calochortus syntrophus is a rare species of flowering plant in the lily family known by the common names Callahan's mariposa lily and clustered mariposa lily. It is endemic to northern California, where it occurs in a remote area north of Montgomery Creek in Shasta County. It has also been spotted in adjacent Tehama County. Its habitat includes open, rocky areas with moist or wet soils in oak woodland territory. It was first discovered in 1993 and its description was published the following year.
This plant produces a thick, waxy stem 40 to 60 centimeters in maximum height. It grows from a bulb which sometimes divides and sends up new stems nearby. The leaves are up to 20 or 30 centimeters long near the base of the plant and those occurring higher on the stem are shorter. The inflorescence is a solitary flower or an umbel-like cluster of up to five flowers.
