Opuntia rioplatensis

A prickly pear named for the Río de la Plata region, where low-growing Opuntia occur on rocky outcrops, coastal dunes and grassland in Uruguay, northeastern Argentina and southern Brazil. There are no usable wild records, so these conditions come from that region's climate and the genus; it is a sun-loving, fairly cold-tolerant cactus.
