Xerophyte

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 of this Ferobergia produce drops of nectar from areolar glands like Ferocactus.

Flowers

Mostly pink or magenta.

Blooming Season

Blossoms intermittently from spring to fall.

Spines

Variable, some plants have long, harmless, and papery spines (more similar to those of Leuchtenbergia), while other others have stouter spines, eventually hooked spines (more similar to those of the Ferocactus).
