|The green fleshy pads, reaching up to 3 inches long, tend to cross over each other in growth pattern. Plenty of yellow glochids cover areoles at about 1 inch apart. The spines are awl shaped and spreading. In summer the slightly warty, scaly large red flowers are borne singly on the edge of the pads and then produce red fruit. This genus has the largest membership of sun loving species. Australia has even banned a few because of their rapid growth.
