LIST OF PLANTS COLLECTED BY DK. E. PALMER IN ARIZONA 



IN 1890. 



By J. N. Rose. 



Dr. Palmer, after haviiip: made large and valuable collections in Lower 

 California and Mexico in tlie early months of the year, visited Arizona 

 during the latter part of April, remaining there through May and June 

 and a part of July. He made collections at Camp Huachuca, Willow 

 Springs, and Fort Apache. A small collection made in 1889 at Oamp 

 Huachuca which Dr. Palmer purchased is included in this report; these 

 plants are designated by letters only. 



Camp Huachuca is about 15 miles from the Mexican border at the 

 base of the Huachuca Mountains, in the extreme southeastern part of 

 Arizona. Its elevation is 5,100 feet above sea level. The mountains 

 are rough and rocky. Tlie soil is of decomposed granite. Dr. Palmer 

 was here from April 20 to May 21, and collected about one hundred 

 species. The season was unfavorable for his work as no rain had fallen 

 for seven mojiths and the mountains and valleys were dry and barren, 

 and the only plants found in proper condition for collecting were in the 

 gardens and in two moist canons. The plants of this collection are 

 numbered fiom 416 to 478; unfortunately the numbers 450 to 459 were 

 repeated, hence the latter are designated by the letter a in addition. 



The only other important collection^ made at this place is that of Mr. 

 J. G. Lemmon and wife in 1882, a very large and valuable one, of which 

 over fifty species wore new. 



Willow Springs is in the White Mountains near the pass leading to 

 Tort Apache, at an altitude ^ of 7,000 feet. It is 75 miles south of Hol- 

 brookon the Atlantic and Pacific Kailroadand is reached only by stage. 

 The mountains here are covered with oaks and pines, and the two large 

 meadows from which this collection was largely made, kept damp by the 

 springs, were covered with vegetation. Dr. Palmer remained here from 

 June 10 to 25; the nights at this season are very cool, often thin ice is 



1 Mr. Lemmon writes me that Dr. Palmer viaiterl this place once before; as it was 

 ditring the dry season nothing of importance was obtained. 



2 Dr. Rothrock gives the altitudeof the pass 7,400 feet and of Willow Springe 7,195.
