Definition: "Anethum" refers to a type of wild cactus, typically found in arid climates, where it grows in the deserts of North America. It's characterized by its distinctive leaves that are often gray-brown in color and resemble green or yellow stems. The stem itself is usually brown or gray, with large, glossy woolly hairs on one side. This plant has no true leaves and instead exhibits a dense mat of cactus spines covering the surface.
