"Datura quercifolia is a plant of dry hillsides, plains, and disturbed areas. It has lobed leaves that mimic to some extent the look of the Gambel Oak leaf. The white flowers are similar to those of Datura wrightii when fresh, turning more purplish with age. The fruit are thorny. The two celled ovary develops into a four chambered capsule that opens from the top into the four chambers containing the black seeds. The seeds are shaped remarkably like a human brain complete with temporal lobe and sulci." (Western New Mexico University


Description
