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 Ferobergia produce drops of nectar from areolar glands like Ferocactus.

Flowers

Usually yellow, but also pink or magenta.

Blooming Season

Blossoms intermittently from spring to fall.

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).
