Cladophylls

Cladophylls are usually called the prickly part of a cactus. They are flattened and somewhat leaf-like in appearance. The center of each cladophyll usually has a node with small scalelike leaves complete with axillary buds. The scaly look to asparagus is cladophylls. These specialized stems are not only restricted to cacti but are found in some orchids and green briars.
