 WESTERN MEXICO AND ARIZONA IN 1890. 



By J. N. Rose. 



The plants upon which this report is based were collected by Dr. 

 Palmer, in 181)0, in Mexico and Arizona. I>r. Palmer returned to 

 Guaymas March 18, after finishing his collection at Santa Rosalia;^ 

 from this place he went to Alamos, remaining three weeks, and then 

 returned to Guaymas ; from here he proceeded to Arizona, staying 

 three months, and then went to San Francisco and remained until 

 August 23, when he again left for the Gulf of California, expecting to 

 land at Carmen Island, but owing to some regulations of the custom 

 oflficials of Mexico he was carried to Guaymas. He was planning 

 again to visit Carmen Island,^ when an opportunity offered to return 

 to Alamos, and as he was desirous of getting the summer as well as 

 the winter flora, he postponed the trip to Carmen Island and embarked 

 by steamer for Agiabampo, the seaport of Alamos. This second trip to 

 Alamos lasted two weeks, and was very successful, notwithstanding it 

 was interrupted by a severe attack of intermittent fever, which com- 

 pelled him to return to the seacoast. 



The total number of new species collected by Dr. Palmer and reported 

 in this paper is 45, with several new varieties.
