Calochortus umpquaensis is a species of flowering plant in the
This plant was described to science in 1989 when an isolated population of what had been reported to be Calochortus howellii was shown to belong to a separate species.[3] The stem is 20 to 30 centimeters tall and the inflorescence contains one or more flowers. The bell-shaped flower has three hairy white or cream-colored petals, each with a bearded purple-black blotch at the base, measuring up to 3.5 centimeters in length. The fruit is a capsule up to 5.4 centimeters long.[2]

Though rare in general, the plant can be locally abundant, with the population at Ace Williams Mountain containing 400,000 to 800,000 individuals.[1]
Threats to this species include nickel mining, introduced species of plants, and poaching. Logging and grazing of cattle are threats, but these have been mitigated recently on federal lands.[1]
