text: # Cactinae
  
  Cactinae is a subtribe of cacti in the tribe Cacteae. It is notable to cactus-lovers, as it contains the large genus Mammillaria. They all produce globular (turning cylindrical) stems and most produce offshoots freely, although this may take some species up to 30 years. The tubercles are generally arranged in spirals. The principal genera of this subtribe are Coryphantha and Mammillaria.
