Coast Manroot aka Wild Cucumber (Marah oreganus)
This vine of the cucumber family, also known as Bigroot, can climb over shrubs or small trees. The small cucumber-like fruits shown below are not edible, the leaves however, may be. Both are said to be very bitter. There are some reports that the seeds are hallucinogenic; those reports seem to be about Marah fabaceus, a close relative to this plant. We do not advise eating any part of this plant for food or supposed psychoactive effects.
