Oreocereus
Template:Short description Template:Automatic taxobox
Oreocereus is a genus of cacti (family Cactaceae), known only from high altitudes of the Andes. Its name means "mountain cereus", formed from the Greek prefix Script error: No such module "lang". (Script error: No such module "Lang"., mountain)[1] and the Neo-Latin Script error: No such module "Lang"., meaning wax or torch.
Description
The species of the genus Oreocereus grow shrubby, branching only sparsely from the base and reach heights of growth of 2 to 3 meters. Trunks are rarely formed. The erect, pendulous or rarely extended cylindrical shoots are notched or warty between the ribs. The areoles often have long white hairs and dense spines. As they are covered with woolly white fuzz (modified spines), a few species in this genus are sometimes known as the old-man cactus,[2][3] a generic name that also refers to Cephalocereus senilis or Espostoa lanata. More rarely, the old man of the mountain is also used for some species.Template:Refn
The tubular to funnel-shaped, more or less radially symmetrical, orange to red to violet flowers arise near the shoot tip, or sometimes from the terminal cephalium, and open during the day. The flower-tube is straight to slightly curved and sometimes laterally compressed. The numerous areoles on the pericarpel and the flower tube are hairy. The spherical to oblong fruits contain broadly oval, dull or shiny black seeds.[4][5]
