Parry and Southern California Botany 161 



however, still to be found in many places in the San Bernardino 

 and San Jacinto mountains. Late in the summer Parry re- 

 turned to his eastern home. 



He next visited the Pacific coast in 1880, when he accompanied 

 Dr. Sargent and Dr. Engelmann in an exploration of the Pacific 

 coast forests, in connection with the forestry report of the 10th 

 U. S. census. Dr. Parry left the party at San Francisco in 

 September, where he remained until the middle of December, 

 when he came to Colton for the winter. From this place he made 

 numerous excursions by the Southern Pacific Railway to both 

 the Colorado and the Mojave deserts. In the latter desert he 

 discovered Oxytheca luteola growing in the moist sand formed 

 by seepage from the railway water tank at Lancaster, and in the 

 neighboring alkaline soil Kochia calif ornica and Atriplex Parry i. 

 The summer of 1881 was spent in San Francisco, with a June 

 trip to the Yosemite, returning early in December to Colton. 

 In March he went to San Diego, and thence to Ensenada, in 

 Lower California. This trip was made by wagon, and with 

 the party were Pringle, Marcus E. Jones and Orcutt. A num- 

 ber of interesting discoveries were made, among them Rosa 

 minutiflora, Aesculus Parryi and Ribes viburnifolium. 



Dr. Parry soon after returned to San Francisco for the sum- 

 mer, but in November once more settled himself in Colton, and 

 in January, 1883, with Mr. W. G. Wright and Orcutt repeated 

 his Lower California trip of the previous year. Ptelia aptera was 

 then first collected. The summer of this year was spent in the 

 Bay region, and the middle of September he returned to Daven- 

 port, where he remained until the following April (1884), when 

 he sailed for England, passing a year in the land of his birth, 

 studying at Kew, or resting at Ilfracombe, on the Devonshire 

 coast. 



November, 1886, found Dr. Parry again in California, 

 where he remained until the winter of 1888-9, and he again re- 

 turned for the summer of the latter year. He was now devoting 

 himself mostly to monograph work, and traveled much over the 

 state to study the living plants. This led him to make several 

 visits to the southern counties, the last in June, 1889. These 

 studies resulted in valuable papers on such difficult genera as 

 Caeonothus, Arctostaphylus, Oxytheca and Chorizanthe. A re-
