Ferobergia ( Ferocactus sp. X Leuchtenbergia )
Leuchtenbergia is closely related to Ferocactus and they can apparently hybridize producing the plant commonly called Ferobergia hybrid (they're genetically close enough for it to work). These very variable hybrids often have a “chin” at the base of each tubercle.

Family: Cactaceae

Scientific Name: X Ferobergia Glass
Published in: Cactus & Succulent  Journal  (America)  38(5): 177-178. Sept. /Oct - 1966

Origin Garden origin (Nursery produced intergeneric hybrid)

Etymology: The name of the hybrid genus " X Ferobergia " derives from  the contracted names of the two parent genera "Ferocactus" and "Leuchtenbergia " from which this plant has been originated. The  “X” before the name means “hybrid”
 

Description: X Ferobergia is a horticultural intergeneric hybrid, made by crossing one of the various species of Ferocactus (as a female) and Leuchtenbergia principis (as a male). These hybrids are very variable, due to the intersection of characters deriving from the parents. The length of the tubercles and spines are the more variable of the trait and a great variety of forms can be found in cultivation.
Sometime a seedling loses some chlorophyll on the way, and the plants became variegated (see: variegated Ferobergia).
Tubercles:
Generally they have more or less long, three-sided tubercles, often with a basal “chin”, rather than arranged along ribs. The areoles are at the tips of tubercles. Some Ferobergia produce drops of nectar from areolar glands like Ferocactus.
Spines: Very variable, some plants have long, harmless, and papery spines (similar to those of Leuchtenbergia), while other others have short and stout, eventually hooked spines (more similar to those of Ferocacti).
Flowers: Usually yellow, but also pink or magenta.
Phenology: Blossoms intermittently from spring to fall.

Cultivation: It grow easily from seed in cultivation. Despite being revered by many collectors, they are not too difficult to cultivate. Use a very quick-draining mineral mix and water just enough, if possible from below. Water carefully. Lack of water will make the tip of the tubercles yellow. Too much water will make it rot. The Ferobergia has a strong tap root, and should have a deep pot to accommodate it. This can complicate things as a deeper pot dries out more slowly. Keep dry at minimum temperature of 5° C in winter, although it will tolerate brief periods down to -5 degrees. It should be grown in light shade.

Propagation: Seeds or graft, occasional offsets and even cuttings of tubercles (but with little success)
