Toxicoscordion fontanum, common name Small-flower death camas is a rare plant species known only from serpentine marshes in California. It is found primarily in the Coast Ranges from Mendocino County to San Luis Obispo County, with an additional report of an isolated population in the Sierra Nevada foothills in Kern County east of Bakersfield. Toxicoscordion fontanum is a bulb-forming perennial herb. Bulbs are egg-shaped, up to 40 mm (1. 6 inches) long, not clumped together. Inflorescences are paniculate, sometimes with as many as 100 flowers. Tepals are cream-colored, up to 12 mm (0. 5 inches) long; filaments shorter than the tepals.
