Echinocactus calif ornicus 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- 

 fomicus Hortus is referred here by Rumpler (Forster, Handb. Cact. ed. 2. 472. 1885).
