erate peduncles. It is possible that the two species of Kunzia(K. tri- 

 dentata and K. glandulosa) have been confounded in some of the follow- 

 ing localities : 



CALIFORNIA. 



White Mountains. — Common on the east slope, ranging down to 

 1,700 meters (5,600 feet) on the Fish Lake Valley side. 



Mount Magruder. — Common in places, ranging down into Tule 

 Canon. 



Gold Mountain.— Common, ranging down on the south side nearly 

 as low as sagebrush (a little above 1,800 meters or 6,100 feet). 



Hungry Hill Summit. — Common just north of the summit, whence 

 it ranges over the divide (1,760 meters or 5,800 feet) and passes south 

 toward the north arm of Indian Spring Valley to about 1,520 meters 

 meters (5,000 feet). 



Timpalmte and Desert mountains. — A little was seen near Mud or 

 Summit Spring. 



Pahranagat Mountains. — Common, ranging down to 1,580 meters 

 (5,200 feet) on the east slope. 



HyTco Mountains. — Common in places, descending into the broad wash 

 that leads from Pahroc Plain into the middle of Pahranagat Valley. 



Pahroc Mountains. — Common, mixed with Cowania mexicana, Arte- 

 misia tridentata, and Primus fasciculata. 



Juniper Mountains. — Common in the juniper forest between Meadow 

 Creek Valley, Nevada, and Shoal Creek, Utah, where it was just com- 

 ing into flower May 18. A week earlier (May 10-11) it was past flow- 

 ering in the Beaverdam Mountains. 



UTAH. 



Upper Santa Clara Valley. — Common from an altitude of 1,640 meters 

 (5,400 feet) upwards to 1,830 meters (6,000 feet), and ranging thence 

 northward to the Upper Santa Clara Crossing and Shoal Creek. 

 Mostly past flowering in the Upper Santa Clara Valley May 17. 



Beaverdam Mountains. — Common, descending to 1,280 meters (4,200 

 feet) on the east or northeast slope, and ranging down on the west 

 slope to 1,340 meters (4,400 feet). Past flowering and petals all off 

 May 11. 



Coleogyne ramosissima. 



This important zone plant grows in the Grayia belt just above the 

 upper limit of the Larrea; it belongs therefore to the upper division 

 of the Lower Sonoran Zone. The altitude which it requires takes 

 it out of most of the desert valleys and places it on the sides of the 

 desert ranges, where it commonly grows in a narrow belt between the 

 creosote bush {Larrea tridentata) and the sage (Artemisia tridentata).
