Discussion | Dichelostemma congestum can be recognized by its congested racemose inflorescence and deeply bifid perianth appendages that stand away from the anthers to form a corona. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.
