San Jose del Cabo, February 17, Dawson 1165. 



Known only from the Cape District; type from Sierra San Fran- 

 cisco, Baja California. This is a low, stiff, tortuously twigged shrub, 

 the old branches gray, the new reddish brown. The reddish-yellow 

 flowers are described as glabrous, but the above specimen shows a few 

 whitish hairs on both the calyx and corolla. 



Calliandra californica Benth., Bot. Voy. Sulph. 14. 1844. 



San Juanico Bay, Baja California, March 2, Re?npel 31. 



Scattered through middle Baja California from the latitudes of Ro- 

 sario south along the outer coast to Magdalena Bay, the type locality. 

 Goldman (C.N.H. 16:332) cites it also from the Cape District, but 

 the cape population is referrable rather to C. peninsularis Rose. It forms 

 a low stiff bush broadly spreading, its specific ecologic niche being the 

 rocky arroyos. When in bloom through the spring the bright red flowers 

 make it one of the most attractive of the Calliandra.
