Echinocactus californicus Monville (Labouret, Monogr. Cact. 199. 1853), first grown 
from seed supposed to have come from California, but without definite locality, may 
belong here although it has been referred to other species such as F. orcuttii. E. cali- 
fornicus Hortus is referred here by Riimpler (Forster, Handb. Cact. ed. 2. 472. 1885).
