Beaver Dam, Utah, and all the collection of this cactus made by 

 the Death Valley expedition were in Utah or Nevada. 2il 



Erythr^a trichantha Griseb. Gent. 146. 



Schumacher is reporte d to have collected this plant on Santa 

 Catalina Island, 30 but subsequent collectors there have not found 

 it. There is no specimen from Schumacher, or any Santa Cata- 

 lina specimen, in the Gray herbarium, and the authenticated 

 range of the plant does not indicate its presence on the island. 



Erythr^a floribunda Benth. PI. Hartw. 322. 



This has been reported from the mountains of San Diego 

 County, by Mr. Orcutt; 31 but a specimen of his, so labeled, is 

 E. Douglasii Gray. 



Con volvulus Californicus Choisy in DC. Prodr. 9.405, 



This plant is mentioned in Mr. Lvon's paper on Santa Cata- 

 lina, 32 but there appear to be no specimens in existence from him, 

 and others have not found it on the island. Mr. Lyon's plant 

 may have been a form of C. occidentalis Gray. 



Gilia demissa Gray, Proc. Am. Acad. 8: 263. 



The type-region of this species is "S. E. California, and 

 adjacent parts of Arizona," In the Botany of California the 

 supposed California station is "Ft. Mojave, Dr. Cooper." 33 While 

 I am unable to find any evidence of the actual collection of 

 specimens in the state, I have no doubt that it yet will be found 

 in the north-eastern part of San Bernardino County. 



Lemmonia California Gray, Proc. Am. Acad. 12: 162. 



Mr. Lemmon's type is reported to have been collected at "Bear 

 Valley Creek, on the headwaters of the Mojave River." Bear 

 Creek, which drains the valley of the same name, is a tributary 

 of the Santa Ana River, on the intramontane slope of the 

 mountains, and Lemmonia is not found on it. This is a desert 

 plant, and grows, in dry open soil, along the desert base of the 

 San Bernardino Mts. from Cajon Pass to Cox's Ranch, at altitudes 

 between 3,000 and 4,000 feet. And here the Lemmon collection, 

 no doubt, was made.
