H4 Errors in Southern California Plants. [ZOE 



shrub, 2-6 ft. high, is frequent in dry washes of the desert along 

 the eastern base of the San Bernardino Mountains, from the true 

 type station to Byrne's Spring, at 1,000-4,000 ft. alt. It does not 

 grow in or near Cajon Pass. 



Astragalus Coulteri Benth. PI. Hartw. 307. 



Parry and L,emmon's reported station for this plant, "on the 

 Mojave River" is an error. Their specimens came from thesand- 

 drifts about Whitewater Station, on the Colorado Desert, where 

 the plant is abundant. It appears not to reach the higher al- 

 titude of the Mojave Desert. 



Tribulus maximus Linn. Sp. PI. 386. 



The basis on which this species has been included in the Cali- 

 fornian flora appears to be Dr. Torrey's note: "New River 

 Region, Parry." 19 If this was founded on more than a field-note 

 of Parry's, the specimen probably has perished. There are no 

 Californian specimens in either the Gray, Torrey, or National 

 herbaria. Yet both this species and T. grandiflorus Benth. & 

 Hook, may be expected confidently from the region indicated by 

 Dr. Torrey. 



Bernardia myricEholia Watson, Bot. Cal. 2:70. 



This is a plant of the lower altitudes of the deserts. It certainly 

 does not reach the "headwaters of the Mojave River," where Dr. 

 Watson reports Parry and L-emmon as collecting it. They probably 

 got it at Whitewater or Palm Springs, in the Colorado Desert. 

 It may occur on the lower part of the Mojave River, but they 

 made, I think, no collections so far down. 



Euphorbia setiloba Engelm.: Torr. Pac. R. Rep. 5:364. 



Dr. Watson gives "San Bernardino, Parry," as a station for 

 this plant. 20 This is an error; Dr. Parry probably got this strict- 

 ly desert Euphorbia in its type neighborhood, Ft. Yuma, where 

 it has been collected by several other botanists. 



Cereus giganteus Engelm. Emory's Rep. 159. 



This species was inserted in the "Additions and Corrections" 

 at the end of the second volume of the Botany of California, but,
