Marah (the manroots, wild cucumbers, or cucumber gourds) are flowering plants in the gourd family (Cucurbitaceae), native to western North America. They are also commonly called Old man in the ground. The genus (which Kellogg noted was characterized by extreme bitterness) was named for Marah in Exodus 15:22-25, which was said to be named for the bitter water there.
