Glossapetalon spinescens. 



This species was found on the Charleston Mountains, Nevada, near 

 Mountain Spring. 



Rhamnus crocea. 



Common in California in the Canada de las Uvas, and also on the 

 Sierra Liebre; not recorded elsewhere. 



Ceanothus fendleri. 



Common on some of the desert ranges in the Great Basin, where it was 

 observed in the following localities : 



NEVADA. 



Mount Magruder. — Commou-on the main peak with Symplwricarpos. 



Charleston Mountains. — Common on the west slope, in the neighbor- 

 hood of Mountain Spring, from 1,550 to 1,770 meters (5,100 to 5,800 feet), 

 and perhaps higher. 



Highland Range. — Found on the west slope. 



UTAH. 



Beaverdam Mountains. — Common on the east slope, at an altitude of 

 1,340 to 1,370 meters (4,400 to 4,500 feet). 



Ceanothus divaricatus and C. cuneatus. 



These species are common in the chaparral of the west slope of the 

 Sierra and Coast Ranges in California. In Walker Pass they are com- 

 mon on the west slope from 1,430 meters (4,700 feet) downward, and 

 range thence southerly along the west slope of the Sierra nearly to 

 Caliente. 



They are common also on the south slope of the Sierra Liebre. 



.aUsculus californica. 



The handsome California buckeye, Avhich grows to be a small tree, 

 was in full bloom when Ave first saw it, the last week in June, on the 

 west slope of the Sierra Nevada between Kernville and Walker Basin, 

 and in the Canada de las Uvas in the Tejon Mountains, a few days 

 later. It usually grows on the sidehills, towering above the chaparral. 



Acer negundo. 



The box elder requires too much water to be common anywhere in 

 the desert region proper. We found it along a running stream below 

 Old Fort Tejon in the Canada de las Uvas, in California, and along the 

 Santa Clara River, in Utah, but not elsewhere. 



Rhus trilobata. 



In California this species was common on the west slope of the Sierra 

 between Walker Basin and Caliente, and on the Sierra Liebre. In 

 Nevada it was found in scattered clumps on the Charleston Mountains, 

 where it reaches its lower limit on the west slope at 1,550 meters (5,100 

 feet), and on the Pahranagat Mountains, where it ranges down on the 

 east slope to 1,580 meters (5,200 feet). On the Beaverdam Mountains
