About plant names...

This is a cross between Ferocactus peninsulae and Ferocactus emoryi (once called Ferocactus rectispinus.) This cross occurs naturally in the California and the northern Mexico desert, at least in Baja California Sur.

Identification: I found very little about this cactus, except that it is available from several vendors. It is 10-20" (25-50 cm) tall, rounded or flat-topped, with orange or yellow flowers. It has clusters of long central spines, the longest up to [Measure5 cm)] and typically hook-shaped. Spines are reddish brown or white. Radial spines—thin, almost hairlike white spines underneath the central spines, may also be present.
