EDWARD PALMER 353 



gether with a short list of plants from Lerdo, in the state of Sonora, 

 Mexico, at the head of the Gulf of California. At the latter place he 

 collected great quantities of a parasitic fleshy plant, Ammobroma son- 

 oroB, the " oyutch," or sand-food, of the Cocopa Indians. 



In 1890 he spent three months in Lower California, collecting at 

 La Paz, Santa Eosalia and Santa Agueda, as well as upon Kaza Island 

 and the island of San Pedro Martir, in the GuK of California; and 

 three months in southern Arizona, collecting at Camp Huachuca, Fort 

 Apache, and Willow Springs. He also made two trips to Alamos in 

 the mountains of southern Sonora, the first during the latter part of 

 March and beginning of April, the second in the month of September. 

 The results of these expeditions were published by Dr. Eose in the 

 " Contributions from the IT. S. National Herbarium, Vol. 1, pp. 91- 

 128, 1891. In 1893 he collected in southern Idaho. 



He afterwards collected in the more tropical regions of Sinaloa and 

 Colima; at Acapulco, the seaport of Guerrero, from which the galleons 

 of the ancient conquistadores sailed to the Philippines; and in the 

 Territory of Tepic. Several times he has revisited the interior states 

 of Coahuila and San Luis Potosi, collecting among the pines and oaks 

 of the mountains, as well as on the arid plateau and in the warm moist 

 region of the lower land near the Gulf of Mexico. He has penetrated 

 into the heart of Durango, making two trips to the Sierra Madre of 

 that state, once in 1896 and again ten years later, in each case going 

 as far as the newly built railroads would take him and making extensive 

 and often painful journeys to lumber camps and mining regions in the 

 mountains. In 1907 he revisited Tamaulipas, collecting especially near 

 Victoria and Gomes Farias. In 1908 he revisited Chihuahua, this 

 time collecting near the capital and at the neighboring stations of 

 Santa Eulalia and Santa Rosalia. 



His last trip, in 1910, was to the gulf coast, in the vicinity of 

 Tampico, Tamaulipas. 



From all of these expeditions he returned laden with a wealth of 

 material, his specimens remarkable among those of all collectors, not 

 for their prettiness, though they were often beautiful, but for their com- 

 pleteness, showing when possible bark, root, wood and seed-pods or 

 fruit, as well as leaves and flowers. He did not content himself with a 

 single example, but in spite of difficulties would often bring a whole 

 series, to illustrate vegetative foliage and branches as well as flowering 

 branches, knowing that the aspect of the foliage might vary on different 

 parts of the same plant, and that entire plants might differ according to 

 their situation. He accompanied the specimens by accurate notes as to 

 locality, habitat and season, not disdaining to give local names however 

 barbarous they might sound to ears tolerant only of classic Greek and 

 Latin; and he noted the taste and odor of bark and wood and leaves
