Parodia buiningii
Template:Short description Template:Speciesbox
Parodia buiningii is a rare species of cactus native to South America. It is a solitary spherical or oblate cactus only a few inches in height with long, yellow spines. It bears yellow flowers, and produces hairy fruit and black seeds. It is found surrounding the towns of Santana do Livramento, Brazil and Rivera, Uruguay.
Taxonomy
The species was first described as Notocactus buiningii by F. Buxbaum in 1968, and was given its current name by N. P. Taylor in 1968, based on Buxbaum's earlier description.[1] Despite objections from hobbyists (among whom Notocactus species were popular) Notocactus (and others) have now been synonymised under Parodia.[2]
