alt. 6500 ft., in the San Bernardino Mountains, June 18, 1916, 
Chandler. The type of this species was a plant grown at Wash- 
ington from seeds collected in 1872 somewhere in Arizona by 
Palmer. A second collection was cited from Topo Canyon, 
Lower California, Orcutt in 1884, but I can learn of no later 
collections. 
* STANLEYA ELATA Jones, Zoe 2:16. 1891.—On dry banks near 
the head of Wild Rose Canyon, Panamint Mountains (10004, 
May 14, 1915). Only a few plants.were seen, just beginning to’ 
flower. The type was collected at Hawthorn, Nevada. 
OXYSTYLIS LUTEA Torr. and Frem. Frem. 2d Rept. 313. 1845.— 
A few specimens were seen in dry soil at several places along the 
Amargosa River, but only in dry remains (Zabriskie, 9889, May 29, 
1915), but living plants were found in the almost obliterated ancient 
channel of that river near Salt Spring (9877, May 21). The plant 
appears to be strictly endemic in this limited region.
