 "east of the Lower Colorado, lat. 35°, alt. 2,000 feet." 



Surprise Canon, Panamint Mountains (No. 629). This species was published by 

 the same author in the same year under the name if. incina 1 , hut the statement has 

 been made by Gray and Trclease- that, " by an oversight this name was substituted 

 for E. incina, employed in Ives's Report, part 4, p. 27, and has priority of publica- 

 tion." 



Euphorbia serpillifolia Pers. Syn. PL ii. 14 (1807). Type locality, "in Amer[ica]

Croton californicuB Mull. Arg. in DC. Prodr. xv. pt. ii. 691 (1886). Typclocality, 

 "in California prope San Francisco et in arenosis pascuisque prope Monterey." 



This plant is one of the common and characteristic species of the San Bernardino 

 Valley (Nos. 32, 39), often occurring as a weed in neglected fields. It was not seen 

 in the ultramontane region, but was met with again in intramontane California 

 when we entered the Tulare Plains from the Canada de las Uvas. 



Croton setigerua Hook. Fl. Bor. Amer. ii. 141 (1838). Type locality, "on Men- 

 zies' Island, and on sandy banks of the Columbia upwards." 



Commonly known under the name Eremocarpux setigerue. I follow Professor 

 Greene 1 in calling this plant a Croton; not as expressing an opinion that it does not con- 

 stitute a distinct genus, but in order to avoid making a new generic name, since Ere- 

 mocarpus was first used by Reicheribach, in 1837, as a designation for a genus of 

 Hypericaceai.
