THE OPUNTIA TRIBE 
Opuntias form a very large section of 
the Cactus Family. They are usually 
large and quick growing plants. Some 
have flat joints or pads and this group 
is called “Prickly Pear,” “Tuna” or 
“Pletyopuntia.” Tree-like types with 
round cylindric branches are called 
“Cylindropuntias,” “Chollas” (Choy- 
yahs), “Jumping Cactus” and “Cane 
Cactus.” There are also minor groups 
of creeping, clustered and small, 
woody, branching types. 
Grusonia. This is a subdivision of the 
Opuntia Tribe. They resemble the 
Cylindropuntias except that the spine 
clusters are borne on ribs instead of 
separate prominences called tubercles.
