HISTORICAL SUMMARY AND REVIEW OF LITERATURE. Chesnut and Wilcox (1901, p. 52)1 say that "the earlier explorers of the Western, and especially of the Northwestern, United States fre- quently mention the poisonous character of the bulbs of one or the other of the various species of Zygadenus and refer to them as poison camas or poison sego in order to distinguish them from bulbs of two other groups of plants, Quamasia and Calochortus, which were com- monly known as camas and wild sego and were much used for food, both by the Indians and by travelers. Accounts of the poisoning of stock from eating the roots and leaves of various species have but recently been sent to this ; This statement, perhaps, covers the knowledge of the subject up to that date, although the writers have failed to find much in the way of definite statement among the earlier writers that can be re- ferred to this plant. In Wyeth's journal of his second expedition to Oregon (Wyeth, 1899) occurs this statement: 16th. Made down the Sandy S. W. by W. 15 miles then 4 S.
