Corn Lily (Veratrum californicum), NorCal [OC]
Fun Fact: Pregnant ewes ingesting the plant from the 12th to the 14th day of gestation may have prolonged gestation due to the absence of the pituitary gland in the malformed offspring. The most striking malformation is partial or complete cyclopia in which one eye or two fused eyes are in a single orbit with a median skin protuberance above.
Columbian Lily (Lilium columbianum) were also quite prolific
Just a random field we stumbled across in the forest. Northern California.
