Type 3 - Cluster of Balls. Small round stems forming a large clump.

This type of cactus has small stems, no more than two inches (6cm) wide, but multiplies forming a large clump just above the soil. Many genera of cacti do this. However, several families are primarily characerized by this behavior. Those would be Lobivia, Rebutia, and Sulcorebutia. Some of the other families that do this (but are not limited to this kind of behavior) are Mammillaria, Echinopsis, Gymnocalycium, and Notocactus.

Flowers: Like hedgehogs, small clumping cacti like Rebutia are prized for their brightly colored flowers. Almost every color in the rainbow is represented. However, most commonly seen are magenta, pink, orange, and red.
