aboriginal. The Latin word for
bitter, amarus, may have come from the biblical reference. Sigg, Jake “Wild Cucumbers (Marah)”, (California

General: Common throughout the study area; very common on the Castaway's bluffs. Photographed on the Castaway's Bluffs and along Back Bay Dr. between Big Canyon and the old Salt Works dike. (my comments). The Indians of California used the seeds as food, the roots and seeds were used as a fish poison, red paint was made from the seeds and the roots were used as medicine. (Heizer & Elsasser 247). Seeds of Echinocystis spp. were roasted and eaten for kidney trouble by the Calif. Indians. (Murphy 41). The Calif. Indians made necklaces of the seeds, polishing them by rubbing them along their oiled bodies. It is said that Indian children used them as marbles. There is nothing edible about this plant even though it is called cucumber. The enormous root is intensely bitter and Marah refers to the bitter waters of that name in the Bible (Exodus 15:23). (Dale 104). The Indians used the stems for string. (lecture by Charlotte Clarke, author of Useful and Edible Plants of California, April 1987. The seeds have a very interesting method of germinating. The two large radical leaves remain underground sending up the terminal shoots only. They are so tender and succulent that they would be eaten forthwith if they showed themselves above the ground. Oil expressed from the roasted seeds has been used by the Indians to promote growth of the hair. (Parsons 28). The skin of the fruit was used as a luffa. (Forgione, Mary. "Herbology class unearths smorgasbord of edible plants," Glendale Daily News, 7 May 1992, p. 10. (luffa or
