290 NORTH AMERICAN FAUNA. [No. 7. 



UTAH. 



Beayerdam Mountains. — Abundant, ranging down to 1,350 meters 

 (4,400 feet) on toe west slope, and to 1,100 meters (3,000 feet) on the 

 east slope. In full bloom May 11 ; flowers deep rich yellow. 



Upper Santa Clara Valley. — Begins about 13 kilometers (8 miles) 

 northwest of St. George, at an altitude of about 1,280 meters (4,200 

 feet), and ranges thence northerly, scattering over the rocky hillsides. 



Arctomecon californicum. 



One of the most interesting incidents in the botanical line connected 

 with the present expedition is the rediscovery of this elegant poppy, 

 the type of which was collected by Fremont in Vegas Desert, southern 

 Nevada, May 3, 1844.* On the very same spot, and within forty-eight 

 hours of the same day of the month (May 1, 1891), Mr. Bailey and I 

 found the species in full bloom, growing in large patches, and secured 

 a fine series of specimens. With it was a second species equally large 

 and hauclsome, but having white instead of yellow flowers, which proved 

 to be undescribed, and which has been since named A. merriami. A. 

 californicum was afterward found near Bitter Springs in the Muddy 

 Mountains (May 5), and in the Amargosa Desert between Ash Meadows 

 and Oasis Yalley (May 31). 



Arctomecon merriami. 



As stated above, this new and handsome poppy, with white flowers 

 measuring 50 mm (about 2 inches) in diameter, was discovered by Mr. 

 Vernon Bailey and myself in Vegas Desert, southern Nevada, between 

 Lower Cottonwood Springs and Vegas Spring, May 1, 1891. It was 

 found in company with the yellow-flowered species (A. californicum), 

 from which it differs in the leaves and fruit as well as in the flower. 

 The botanist of the expedition, Mr. F. V. Ooville, has paid me the 

 compliment of attaching my name to the species and has figured it in 

 his forthcoming report.! 



Stanleya pinnata. 



This miserable crucifer, which attains a height of 4 or 5 feet, has a 

 woody base, while the top is herbaceous. It was not seen in Utah nor 

 eastern Nevada, but was common in some of the deserts of western 

 Nevada and eastern California. It or a closely allied species was noted 

 at the following localities : 



CALIFORNIA. 



Owens Valley. — Common in places, and ranging up the west slope of 

 the White Mountains to 1,970 meters (6,500 feet). 

 Beep Spring Valley. — Common in the higher parts of the valley.
