Dichelostemma multiflorum is similar to D. capitatum and D. congestum. Dichelostemma capitatum is distinguished by its six fertile stamens, and D. congestum by perianth appendages that are deeply bifid and lean away from the inner anthers; racemose inflorescences; and a weakly constricted perianth tube.
