During the month of August, 1915, the writer and Mrs. Pammel spent a month visiting California. Our journey took us over the Western Pacific railroad from Salt Lake City. This railway passes over the Sierra divide and down the Feather River canyon, down the Yuba and Sacramento flood plains, thence into San Francisco. At several points along the line stops were made and some collecting was done. From San Francisco we went over the Southern Pacific to Big Trees, Santa Cruz, Monterey, Santa Barbara and Los Angeles —from the latter point over the Santa Fe to San Diego and return up to San Bernardino. At each of these places we stopped and had an opportunity to collect plants and make notes on the more common weeds.
