Bishop's flower (Visnaga daucoides)
Description
Ammi visnaga is a species of flowering plant in the carrot family known by many common names, including toothpick-plant, toothpickweed, bisnaga, and khella. Also known as Bishop's weed. It is native to Europe, Asia, and North Africa, but it can be found throughout the world as an introduced species. This is an annual or biennial herb growing from a taproot erect to a maximum height near 80 centimeters. Leaves are up to 20 centimeters long and generally oval to triangular in shape but dissected into many small linear to lance-shaped segments. The inflorescence is a compound umbel of white flowers similar to those of other Apiaceae species. The fruit is a compressed oval-shaped body less than 3 millimeters long. This and other Ammi species are sources of khellin, a diuretic extract.
