NORTH AMERICAN AMYGDALUS WIGHT 137 



A shrub or small tree 5 m. high with irregular more or less spinescent 

 branches and reddish bark, originally described from "Coast Ranges of 

 Southern California; Oriflamme Canon, San Diego County (D. Cleveland) ; 

 San Bernardino, Parry and Lemmon, n. 108, 1876. Also collected by Fre- 

 mont in 1846, locality uncertain." The species occurs in southern Cali- 

 fornia from the Chuckawalla Mountains southward to northern Lower Cali- 

 fornia. 



The type sheet of this species in the Gray Herbarium at Cambridge 

 contains with other specimens a fragmentary one collected by Fremont 

 probably in 1846, but this is Primus subcordata and was evidently taken by 

 Watson to be identical with the other material and Fremont's name was ac- 

 cordingly given to the species, though it is doubtful if he ever collected it.
